"Doing the Basecamp data science bootcamp was a great decision because it brought me a long way in the space of only two months and I am so much more confident with data and machine learning now. This is all thanks to the patience and encouragement of Juraj and the other mentors. Topics were taught by experts in their respective fields and were taught in an engaging way. Even though some of the topics were difficult to grasp, Juraj went out of his way to make sure we understood the most important points. I really enjoyed it and I have away so much from the experience."

"The courses were clearly built with love, and the instructors' enthusiasm for the subject shows in every exercise. Fantastic user experience! Not a fan of 'input box learning' like Codecademy etc. and in truth, you won't become a data scientist with Data Camp alone. However, data science is something that many people need a little hand-holding, so the format of instruction lends itself well to the content."

"I was on the K2 Data Science program part-time track. I had little experience with machine learning by doing some academic projects. I was working full-time and could not move to a location or quit my job to pursue my interest in Data Science. It has a great comprehensive study material and good assignments and projects which can be done at a flexible pace. My mentor and the TA's were very patient with my schedule. My mentor Pavitraa did a great job at making sure I got the concepts right and also helped me prep for my interviews. Overall it was a very pleasant experience."

"Being in the S2SD programme was a great experience for me. During the 5 weeks that it lasted, I worked full time with a team of 4 people in a real data science project, in which we were able to help a company and provide business insights for them. Apart from the technical skills that I acquired or improved (Python, SQL, machine learning libraries, natural language processing...), I gained a lot in terms of communication,team-work, and remote working.

The mentors from Pivigo were very helpful in keeping the team united and solving all sorts of technical issues. To sum up, being in the S2DS programme helped my career by improving my key skills (technical and non-technical) and giving me more confidence when facing new data science projects and meeting recruiters for interesting jobs."

"When I decided to join Data Science Europe I was not really sure what to expect and whether I will be able to learn all the things promised on the website. But already after the first week, I knew that I had made the right choice in taking the course and that I would learn a lot, e.g. Hive/SQL and machine learning models.

Without the course, I would have needed much longer first to find out what I need to learn and second to review the material."

Not only was Giulio a great teacher for the technical material, but he was also an excellent advisor for building a network, applying for jobs, and preparing for the interviews. What I liked best about the program was that the material we covered was well selected in terms of skills needed for getting a job as a data scientist."

"I attended Flatiron School's Access Labs program in Brooklyn and graduated this past January. Since then I have been hired as Junior Frontend Developer, and I can say that it was the absolutely right decision to attend Flatiron. I was very unsure how their reputation stacked up in the real world and what the quality of the education was. I looked into App Academy, and Fullstack as well, and was accepted at Fullstack, (I didn't apply to App Academy).

Ultimately I choose Flatiron because the timing of the cohort was better for me, and the financing option with the Access Labs program is awesome. I currently work with App Academy graduates and they are all top notch and know other people who are Fullstack graduates that are excellent programmers too. I didn't find the boot camp experience to be crazy overwhelming, it's hard work for sure, but if you have a mature attitude and work ethic you'll be fine. Flatiron will teach you how to code, how to build applications, provide a working understanding of how code operates and how the frameworks and languages communicate with each other. If you choose not to do the hard work, you'll still probably graduate but you've just cheated yourself. Like anything in life you get out of it what you put in, and Flatiron has a ton of resources for those who engage and want to learn. Flatiron does an excellent job of helping their students develop their soft skills too, and they offer talks and workshops with working developers.

When you graduate you'll still have a lot of knowledge to fill in, data types, and algorithms, CS concepts, etc. You need to do the work and learn this stuff. Flatiron has a robust career staffing team that actively engage and assist their graduates find jobs, lifetime career coaching support, job fairs, mock tech interviews, and more. This aspect of the school cannot be understated, they offer a lot of job hunting support. The teaching assistants are excellent and extremely helpful, the teachers, for the most part, are senior devs that have switched to teaching. Flatiron can improve by implementing more code reviews of student projects, and by having stricter requirements for passing course sections.

I saw some students that would have benefitted from more focused support from the teaching staff but instead were passed to advanced sections without fulling grasping the concepts. If you as a student feel like you are falling behind you need to take the initiative to get the help you need. All in all, I am very happy with my decision to attend Flatiron, I now have the best job I've ever had."

Never would I have thought I would be where I'm currently at in life. My instructors at the DTLA campus are amazing and very dedicated to teaching and preparing their students for a job in tech. Of course, at the end of the day, it is all up to the students to put in the work and apply those skills.

The curriculum is very well designed to take you to the level needed to be hirable after completing the course. As for the job search, it all comes down to you. It's a little hard at the beginning but once you have your foot in the door your in. Most tech interviews are the same so the repetition of interviewing helps in your favor. software engineers are in such high demand there are open positions everywhere in tech. The skills you learn at GA get you one of those positions but like I said it's all up to you.”

“Level is a very intensive 8-week course focused on teaching you data analytics and data science. I really enjoyed my time at Level. I believe I definitely got my money's worth and the capstone project was extremely useful. Though, ties with Northeastern and their resources proved to be a huge bonus as well. I'll start with the capstone because that is the most important part of this class. You are paired up with a real company with a real problem that you have to solve.

This is immensely motivating as I am very interested in education and was paired up with Raising A Reader in MA. Working with real data and real employers is the best way to test the skills you learn. The curriculum was very sound. Everything that you learn will be applicable and is exactly what employers are putting in job descriptions of their open Data positions. I was especially taken in by the section on R. Once I started using R, it was hard to turn away.

You should definitely have an idea of the very basics of programming. It will help you learn much more while you are there. My instructor was Dale Joachim, and I could not have asked for a more enthusiastic, professional person to lead the class. I believe his curiosity made the lectures much more intriguing and helpful”

“Attending SPICED Academy was one of the best decisions I have made. Since I was moving from the US to Berlin for this course, I did a substantial amount of research in order to find the right school for me and I ultimately chose SPICED. I applied in March 2018 to start in the October 2018 cohort and during that time I completed the prep course work several times to get a good grasp on the concepts.

I joined the bootcamp as a complete beginner and once I finished the course, I was amazed at the incredible progress I made, how much I learned, and the applications I was able to build. The teachers are incredibly helpful and always willing to help you work through a problem but also ensure you understand why that problem occurred in the first place. That being said, this course is also incredibly demanding - it is a bootcamp after all!

I spent an average of 10-12 hours every day at school for 6 days of the week. This is a fast-paced learning environment where you are challenged on a daily basis and expected to learn by doing. One of the first things I learned at SPICED was getting comfortable with certain parts of your application not working and how to patiently troubleshoot and work with your peers to figure things out together. This is all part of the learning process! There were times when I was incredibly frustrated and other times when I was overjoyed because I made something work on my own. In all, I absolutely recommend SPICED for anyone interested in making a commitment to learning programming.

It was a gratifying experience that provided me with the skills necessary to apply to the workplace as a junior developer. You just have to be willing to put in the work in order to truly see progress in your abilities and get the most out of this course.”

“I enrolled in the Data Science career track. I completed my course a couple of weeks back. I opted out of the career assistance because I already had a job which I am not planning to quit any time soon. I completed my course work. I had to interrupt my course twice. Once due to flooding and the other time when I was about to be a father.

On both occasions, Springboard paused my course and was supportive of me resuming it later.

Pros:-

1. Structure: The course is well structured and gives you a good idea of how to progress
2. Exercises: There were a lot of exercises which gave a very good insight into how a data science project progresses. This included basic and intermediate statistical analyses and advanced topics.
3. Projects: Two capstones make you practice a lot. The capstones along with mentor guidance solidified many concepts in my mind.
4. Mentors (Biggest Pro): Having a mentor was the biggest pro. I was matched up to an excellent mentor, an expert in the field and he was extremely patient with me and always pushed me in the right direction. I understand a mentor can be different for different people but if they match you up with a mentor who is helpful, extract everything from the opportunity.

Cons:-

1. I felt that not enough attention was paid to big data and data engineering. Maybe they will fix it in the future.
2. The content was...ok. You can find equally good video materials on YouTube if not better materials.

Overall:- It's a very good program for the amount of money you pay. I am not sure about the job support but based on the quality of my mentors, I am sure that is solid too..”

“I spent a good few weeks researching all the available boot camps - emailing alum and current students to find out what they thought. With Thinkful - the overriding feedback was that the course was great as long as you were willing to work hard and do what you need to succeed.

Thankfully, that's what I planned to do! What separated Thinkful from the others was that they offered the money back if they didn't help land you a role within 6 months of graduating. To me, that spoke highly of how successful they believe themselves to me.

They were willing to put their money where their mouth was - again, as long as I played my part! I attended the flex course, which meant I could continue working full time. It worked perfectly for me, and I loved that I was able to meet twice a week with a mentor to help me push through the barriers that slowed me down to allow me to keep on growing..”

Data Analytics

Data analytics involves the process of using specialized computer systems to extract meaning from raw data. During the process, patterns are identified and conclusions are drawn after transforming, organizing, and modeling the data. So basically, it is used to describe the analysis of large volumes of data. This presents unique data handling and computational challenges that can be overcome by skilled data analytics professionals.

To become a data analyst, one must have knowledge of a programming language like R or Python, statistical skills, machine learning skills, communication and data visualization skills, data wrangling skills and finally data intuition.

According to Glassdoor, the average annual salary of a data analyst is $60,476. With more and more sectors adopting data analytics, the demand for data analysts has increased. In the healthcare industry, a high volume of structured and unstructured data is used by data analytics to make quick decisions. Also, in the retail industry, data analytics is used to fulfill the demands of shoppers.

DATA ENGINEERING

Data Engineering is an aspect of Data Science that deals with the practical applications of data collection and data analysis. Data Scientists collect and validate the large set of information to deliver insights and answer questions.  So, there needs to be a mechanism for collecting that information and applying it to real-world operations. This is the job of a Data Engineer: applying science to practical and functional systems.

The role of a Data Engineer is to find how to harvest and apply big data. There is not much analysis or experimental design. They create the technology and interface for collecting and ensure the easy flow and access to that information. They are experts in programming, system architecture, interface and sensor configuration, and database design & configuration. They build the data store that is used in providing insights after combining and querying big data sources. Many organizations like Hadoop vendor, Cloudera Inc, and IBM have started offering certifications for data engineering professionals.

BIG DATA

Big data refers to the large volumes of data that can be structured or unstructured. If this data is analyzed and converted into insights, it leads to strategic business moves and better decisions. This data can enable time reductions, cost reductions, smart decision making, optimized offerings, and new product development. Combined with high-powered analytics, big data can be used for a lot of business-related tasks like determining the cause of issues, defects, and failures, calculating risk portfolios, generating coupons based on the buying habits of the customer, and detecting fraudulent behavior.

We have so much data that we have collected since the dawn of the digital age. Today, we create as much data from the beginning of time until 2000 in just 2 days. This growth is not going to reduce anytime soon. Almost every move that we make leaves a digital trail. Whether we are communicating with our friends, using social media or just shopping, we are leaving digital footprints. By 2020, the data available will have grown to 50 zetta bytes from just 5 zettabytes.

Machine Learning

Machine Learning is a branch of Artificial Intelligence that automates the analytical model building. We know that systems can not only just identify patterns after analyzing the data, but also make decisions without any human intervention. Most of the industries that deal with large volumes of data have understood the value of Machine Learning. Gaining insights from the data helps these industries work efficiently and gain an advantage over their competitors.

With a tremendous growth rate, we will soon be seeing the applications of Machine Learning in all of the major domains. According to IFI Claims Patent Services, between 2013 and 2017, there has been a growth rate of 34% in the Machine Learning patents. Most of these patients were from major tech companies like Microsoft, Google, IBM, LinkedIn, etc. In a survey done by Google Cloud and MIT, about 60% of the organizations have started implementing Machine Learning strategies. The Machine Learning technologies are helping these organizations automating several processes which in turn is increasing their productivity.

ARTIFICIAL INTELLIGENCE

Artificial Intelligence is the simulation of human nature and intelligence processes by computer systems or simple machines. These processes include learning (acquiring information and rules), reasoning (using the learned rules to reach conclusions), and self-correction. Artificial Intelligence has application in several fields including speech recognition, expert systems, and machine vision.

Artificial Intelligence has found major application for organizations looking to automate and optimize their processes by extracting the value from data and producing actionable insights. With Machine Learning, Artificial Intelligent systems are able to use a large volume of available data to discover patterns and deliver insights. This would be impossible for humans. Companies are now able to predict critical care events, deliver targeted & personalized communications, identify fraudulent transactions and much more.

According to Harvard Business Review, in the coming decade, the effect of AI is only going to increase. Slowly, every other industry including manufacturing, healthcare, retailing, entertainment, insurance, law, transportation, finance, advertising, education, etc. are going to transform their business models and core processes to take advantage of Machine Learning.

Named as the sexiest job of the 21st century by the 2012 edition of Harvard Business Review, the role of a data scientist has become a popular career choice for a number of good reasons. Big corporations like Facebook, Google, etc. accumulate the user data and sell them to the highest bidder to gain huge margins on their profits. Data is the answer to many questions like - how is a website like Amazon able to predict and recommend products that a consumer is more likely to buy? Or the fact that when surfing the net, you get ads specifically for items that you were looking to buy on the internet a few moments or days back? Some other major reasons why data science is a popular career choice today are:

1. The industry has started giving more importance to data-driven decisions.
2. The demand for data scientists is very high, while the supply is too low, so the salaries are still very high.
3. Due to data explosion in recent years, an enormous amount of data is being collected and data scientists are needed to make sense of them. The analysis also helps the market move in a consumer-centric direction.

Data Science Career Path :

A mathematician, a computer scientist, and even a trend spotter - all these are the characteristics of a data scientist. Their job is to decode and make sense of large amounts of data. This data is then efficiently analyzed with inferences made and presented to all the stakeholders who can be both, technical as well as non-technical. There are multiple career paths in data science which are explained below:

Business Intelligence Analyst: One of the most important applications of data science is used by a Business Intelligence analyst. It is the job of a business intelligence analyst to analyze the data to create a clear picture of the direction the business needs to go in and tap-in on both, business as well as market trends.

Data Mining Engineer: A data mining engineer, as the name suggests mines the relevant data for an organization. The main job of a data mining engineer is to examine the data for the needs of the business. Other than this, a data mining engineer also needs to keep on creating/improving algorithms that would further help improve the analysis of the data itself.

Data Architect: A data architect has to work together with developers, system designers, and users as well to create blueprints which are used by data management systems for the integration, protection, centralization as well as maintenance of the data sources.

Data Scientist: The main job of a data scientist is to further the interests of a business through the analysis of data given to them. They should drive a business case by analysis, development of a hypothesis, and the development of an understanding of data. This would help in exploring relationships between the different data points in the data set.

Senior Data Scientist: This is a role for someone who is experienced in this field. The responsibility of a senior data scientist is to predict and anticipate what the business needs could be in the future, and accordingly fine-tune projects and analysis.

We have compiled a list of 8 top skills one needs to become a successful data scientist:

1. Python Coding
2. R Programming
3. Hadoop Platform
4. SQL database and coding
5. Machine Learning and Artificial Intelligence
6. Apache Spark
7. Data Visualization
8. Unstructured data

1. Python Coding: Python is the language of choice for most when it comes to data science. There are many reasons for its popularity among the data scientists, some of which are - its versatile nature which allows Python to be used for many different kinds of applications; simplicity is also a major factor, Python language is easy to read and write; most important of all is the thriving open source community that Python has worldwide which keeps adding to the features of this programming language.
2. R Programming: R programming is preferred by many in the data science field due to the number of tools it offers while programming. Being proficient in at least one of the many analytical tools it offers is important if data science is going to be your choice of career.
3. Hadoop Platform: Although not mandatory, this is an important skill  to have for a career in data science. According to a study done by CrowdFlower on 3490 LinkedIn data science jobs, Hadoop is the second most important skill to become a data scientist.
4. SQL database and coding: Learning SQL database is an important task to do for any data scientist enthusiast. MySQL offers quick commands that save time while performing operations on the database while also decreasing the level of technical expertise required to manage it.
5. Machine Learning and Artificial Intelligence: Machine learning is becoming the next hot prospect in the tech industry and its applications are endless. It is a field of data science as all Machine learning algorithms are applied to data. If you want to become a successful data scientist then proficiency in these skills is necessary. A data science enthusiast should have good command over the following:
1. Reinforcement Learning
2. Neural Network
3. Adversarial learning
4. Decision trees
5. Machine Learning algorithms
6. Logistic regression etc.
   
   
6. Apache Spark: Apache Spark is a big data computation tool and is also one of the most used data sharing technologies around the globe. Data scientists prefer Spark over Hadoop due to its speed. Apache Spark is faster due to the fact that it makes caches of the computations inside system memory while Hadoop uses the disk for read/write operations.
   Easy to use and high-speed computations are what makes Apache Spark stand apart. The tool is used to make the algorithms run faster. It significantly helps in the division of data processing of large chunks as well as in the case of complex and unstructured data sets. Apache Spark prevents any loss of data.
7. Data Visualization: A data scientist is just given a large chunk of data and tasked with analyzing it. To make relations between different data points, it is imperative that a data scientist has skills to use visualization tools such as d3.js, Tableau, ggplot, and matplotlib. When data scientists create results from the data, these tools help to put these results in a visual format for everyone to understand it better. One of the most important aspects of data visualization is that it significantly helps the organization in a way that brings them closer to the customer’s experience and needs by working directly with the data. Data scientists are able to gain insights from a particular data and consequently use that result to act on a new outcome.
8. Unstructured data: Data given to data scientists is largely unstructured, so it is essential that a data scientist is aware of the necessary skills required to manipulate unstructured data as well. Unstructured data generally means content without any labels and unorganized into database values. For example, videos, social media posts, audio samples, customer reviews, blog posts, etc.
   

For any successful data scientist, below are the 4 essential behavioral traits that one must have -

• Curiosity – Dealing with a huge amount of data every day can become mundane and so it is important to stay curious to discover new insights from raw data.

• Clarity – Data Science is a huge field and you may end up getting confused about why you are doing what you are doing. It becomes imperative that you understand the need at every step and why it is the best way to do so as well.

• Creativity - Main aim in data science is to visualize or manipulate data in a way that makes its analysis simple and easy to comprehend, so data scientists should always keep thriving for innovative ways to do so. Keeping abreast of latest visualization tools can help.

• Skepticism – Skepticism is an important behavioral trait that distinguishes data scientists from other creative minds. As a data scientist, you would have to be skeptical about how you use and analyze data.

Being a part of the ‘Sexiest Job of the 21st century’, as quoted in Harvard Business Review, has its own benefits. Below are the top 5 proven benefits of being a data scientist-

Below are the steps which you can follow in order to become a successful, top-notch data scientist:

1. Getting started: First of all, choose a programming language of your preference. Be also wary of the tools it offers in the ML field. We recommend Python or R programming language.
2. Mathematics and statistics: Data science is nothing without mathematics and statistics. All the data given to a data scientist is in its raw form and with the help of tools, mathematics, and statistics, it is transformed into  patterns that exhibit different kinds of relationships between data points. It is, therefore, a must that you have a good command over both, mathematics as well as statistics.
3. Data visualization: A part of the job of a data scientist is to visualize the data. Sometimes it is the end result, but many times visualization of the data is needed to understand it and help it analyze better. For communication with all stakeholders, it is imperative that you know how to visualize the data and present to even a non-technical stakeholder.
4. ML and Deep learning: Data science and Machine learning go hand in hand, so if you want to become a successful data scientist then grasping and implementing machine learning techniques to tackle problems is mandatory. Deep learning is another aspect of ML that is heavily used because of the efficiency it provides with large data sets. It is strongly advised that you get yourself some valuable experience in both, Machine learning as well as Deep Learning.

Being declared as ‘The sexiest job of the 21st century’, the job of data scientist naturally demands an equally flashy academic background. If you are looking to become a successful and top-notch data scientist, look no further as we have compiled a list of key skills and steps you can follow on the path.

1. Degree/certificate: It is no secret that most of the data scientists are academic scholars. Most of them have completed their higher education be it Masters or even Ph.D.’s. Completing these degrees require you to do intensive research to help you get accustomed to the tools that real data scientists use for real-world problems. These courses impart fundamental knowledge and teach how to use cutting-edge tools. Certificates also help in a significant way. They garner global recognition by adding credibility to your skills and make your CV attractive to the employers.
2. Unstructured data: The primary data which data scientists have to work with is unstructured. It is the job of the data scientist to structure it and make it fit inside a database.
3. Software and Frameworks: Softwares and frameworks are the tools used by the data scientists to deal with the huge chunks of unstructured data. Therefore, it is essential to be proficient in using the software and frameworks to go along with a suitable programming language for you, preferably R.

1. It is important to know that at least 43% of data scientists use R language for their data analysis despite it having a steep learning curve. This really goes on to show that the benefits of R are huge and so are the returns you get after learning it.
2. When your data exceeds the memory capacity that is used to process it, tools such as Hadoop come in handy. This framework relays the data to different points in the machine. Spark, Hadoop’s counterpart, is also gaining popularity after Hadoop itself. It is also used for processing and computation work like Hadoop but is much faster than its counterpart. One major advantage of Spark is that it prevents loss of data during processing and this feature is not provided by Hadoop.
3. c. After you process the data, you would be needing a database to store it and use it for later analysis. Therefore, it is important that you are proficient in databases as well. The most popular skill found in most of the data scientists is of SQL.

4. Machine learning and Deep Learning: After gathering and preprocessing the data, comes the step to inject it into your model. This is where you employ your ML and deep learning skills.

5. Data visualization: Data visualization is an important part of the job for data scientists. As the industry is moving towards data-driven decision-making systems, it becomes essential that all the stakeholders, technical as well as non-technical, are able to understand the data and make customer-centric decisions through charts and graphs provided by the data scientists. Some of the famous tools which help fulfill this are matplotlib, ggplot2, etc.

According to a survey, more than 90% of data scientists hold a degree. That distribution is further divided such that 49% of them hold Master’s while 41% are Ph.D.’s.

A degree helps in various ways in the data science field  –

• Networking – Pursuing a degree helps you meet like minded individuals and network. This network can  eventually help you search for an appropriate opening or get good references that can increase your chances of landing a job.  

• Structured learning – A degree course imparts knowledge in a structured way so that every concept is clearly understood with a clear picture in mind of the whole syllabus. The curriculum is also designed in a way so that it incorporates all the latest trends and is, therefore, more effective when compared to doing learning in an unplanned manner.

• Internships – Internship is an important part of your degree program. The aim of an internship is to get real-world experience.

• Recognized academic qualifications for your résumé – A degree is something which you can show in your resume and will give you more preference in the race for top jobs.

Getting a Master’s degree is definitely beneficial to your career but it is not mandatory. You can determine whether you need a Master’s in Data science or not by evaluating yourself in the below questionnaire. If you score more than 6 points, then earning a Master’s degree is recommended.

Without a doubt, knowledge of programming languages is invaluable and a must for any data science enthusiast. Some major reasons why knowledge in programming is mandatory in the data science field include:

• Data sets: As is known, there is generally a huge amount of data that is to be processed by a data scientist and these data sets are not always preprocessed. Therefore, your programming language skills help you here by aiding you to tackle both, large as well as small data sets with much ease.

• Statistics: Ability to work with statistics is significantly improved by programming skills. If a data scientist is proficient in statistics and not in any programming language then even the knowledge of statistics decreases in its usefulness.
• Framework: Frameworks are important in a way that organizations use them to automate experimenting, visualization of data as well as managing the pipeline at some large organization. And programming is the key to create a suitable and appropriate framework.
