Data Science with Python Training in Hyderabad, India

Hyderabad is home to many renowned technical universities such as IIIT Hyderabad, Havisha Institute, Indian School of Business, Imarticus Learning, University of Hyderabad, Data Analytics Park, etc.which offer courses in the field of data science. The essential skills needed to become a Data Scientist are as follows:

• Python Coding
• R Programming
• Hadoop Platform
• SQL database and coding
• Machine Learning and Artificial Intelligence
• Apache Spark
• Data Visualization
• Unstructured data

1. Python Coding: Python is one of the simplest and most popular coding systems used by Data scientists. It is a versatile and easy to use programming tool that takes various formats of data and processes them. Python also helps in creating datasets and allows data scientists to perform operations on those datasets.

2. R programming: The knowledge of at least one analytical tool is useful in taking forward your data science journey and becoming an expert. R programming is one such tool, knowledge of which will make any data science problem easier to solve.

3. Hadoop Platform: This is an open source framework that processes and analyzes huge volumes of data. It is provided by Apache and is a major requirement for most data science jobs even though there are better alternatives available for it.

4. SQL database and coding: SQL is the language in which data is created. Thus data scientists need to know this language in order to analyze, communicate as well as work on data and understand the structure and formation of a database. MySQL also possess concise commands to make operations on a database easier, while saving time and decreasing the number of technical skills needed by a data scientist.

5. Machine Learning and Artificial Intelligence: It is mandatory to have a proficiency in the subject of Machine Learning and Artificial Intelligence for professionals who want to pursue a career in data science. Some of the major concepts and knowledge of ML and AI that are necessary to learn are:

• Reinforcement Learning
• Neural Network
• Adversarial learning
• Decision trees
• Machine Learning algorithms
• Logistic regression etc.

6. Apache Spark: Apache Spark is a developed version of the Hadoop Platform. It is one of the most popular data computation and sharing platforms with the only difference from Hadoop being that Apache Spark is faster than Hadoop. While Hadoop reads and writes to the disk, Apache Spark creates caches of its computation in the system memory. Apache Spark is the effective way of running data science algorithms faster. It helps in the faster dissemination of processed data while making handling of unstructured data set easier. It also diminishes the loss of data and is a faster alternative making it easier for data scientists to carry out projects.

7. Data Visualization: Visualization tools like d3.js, ggplot, Tableau and matplotlib helps data scientists visualize data. Complex data obtained from performing processes on data sets needs to be transformed into easy formats that can be comprehended by data scientists. Data visualization enables organizations to work directly with the obtained data. The knowledge and outcome obtained from a particular data can be directly used on new data.

8. Unstructured data: These are the content that are not labelled and organized into database values like videos, social media posts, audio samples, customer reviews, blog posts etc. Data scientists need to work with such unstructured data.

5 behavioral traits are needed in order to become a successful data scientist. 

1. Curiosity: To work as a data scientist one needs to deal with a massive amount of data on a daily basis. For that one needs to have an insatiable hunger for knowledge to keep going.
2. Clarity: Having a thorough idea of what is going on around you and ‘why’ and ‘what’ you need to do is essential. Whether cleaning data or writing code, one should have clarity on what needs to be done and why.
3. Creativity: Creativity is absolute for any form of work, whether it is visualizing data, developing new tools or new modeling features. Being aware of what is missing and what needs to be done when faced with a problem is necessary to get the right results.
4. Skepticism: One of the perils of creativity and being a successful data scientist is getting carried away by your own creativity. Skepticism keeps a data scientist in check and rationalizes the creative mind to find the right solution and not get attached to their own invention.

Living in Hyderabad is highly beneficial for a data scientist as it is home to some of the elite universities such as IIIT Hyderabad, Indian School of Business, Imarticus Learning, University of Hyderabad, Data Analytics Park, etc. and companies like Microsoft, IBM, Amazon, Franklin Templeton, INVECAS, Thrymr Software, Woodcutter, PayZello, etc.

Moreover, when more than half of the world’s population is using something you are an expert in, you will definitely get to enjoy its benefits.

1. Highest paying job: It is said that the greater the peril better the reward. Qualifying as a certified data scientist needs a lot of training and hard work, thus the pay has to be proportionate to the work put into it. There is a high demand for data scientists but a limited number of trained professionals out there. Hence, data scientists earn one of the highest salaries in the IT sector today. Today, the average salary for a data scientist in Hyderabad is ₹8,55,143/yr.

2. Great bonuses: Apart from the salary, data scientists get huge bonuses including equity shares and signing perks.

Getting started: Learning any programming language is the best way to start your journey as a data scientist. The most common programming languages are the R and Python programming. Having an idea of what data science is and what type of jobs it entails should be the first priority.

Mathematics: Data science is the study of data. It requires raw data to be stored, segregated and finally interpreted, which requires both mathematics and statistics. Having good command over few of the aspects of statistics can be quite helpful in data science, like:

• Descriptive statistics
• Probability
• Linear algebra
• Inferential statistics

Libraries: Data science is an advanced level of inventory making. Thus it not only preprocesses the data, but plots it as structured data and then uses AI algorithms on it to create databases. Some of the most popular libraries are:

• Sci-kit learn
• SciPy
• NumPy
• Pandas
• ggplot
• matplotlib

Data Visualization: Having the presence of mind to categorize the raw data, finding similarities and being able to simplify the data for easy understanding is to visualize the data. One of the popular forms is graph. There are various libraries you can use to make it easier for you:

• matplotlib-Python
• gglpot2-R

Data preprocessing: Data scientists start with a large mass of data that needs to be preprocessed in order to be analysis ready. The preprocessing is done with feature engineering and variable selection. After this it is fed to ML tools for analysis.

Deep learning and ML: Machine Learning and deep learning are the medium through which data is analyzed. The preprocessed data will work only with deep learning algorithms in order to analyze such huge number of data. Both deep learning and ML are mandatory for your job application to be even considered. One should spend a few weeks reading up on CNN, RNN and neural networks.

Natural Language processing: One should have knowledge of NLP as it helps in analyzing text form of data and classifying them as well.

Polishing skills: There is no end to knowledge and competitions are a great way to brush up on your programming skills. Online platforms like Analytics Vidya or Kaggle have opportunities to keep working on your data science concepts. Outside online platforms you can make your own projects and study it.

If you think you are prepared to take an interview as a Data Scientist, the following ways might help you prepare for the interview.

Study: Reread whatever you have learnt till now. There are few things you could brush up on:

• Probability
• Statistics
• Statistical models
• Machine Learning
• Understanding of neural networks.

• Python is a versatile multi-faceted programming language: Python is easy to use and comes with various libraries and packages that are useful to data scientists. It is structured and object oriented making it perfect for data science.

• Python is the most simple and readable programming language that instantly attracts data scientists. It comes with appropriate analytic libraries and tools that are ideal for the kind of work done in data science. It is unique in relation to any other programming language making it the only choice for all data science projects.

• The diversity of resources available on Python makes it a safe option for data scientists. Even if faced with a problem data scientists have a broad area of resources available to quickly work up a solution while working on a Python program or developing a data science model.

• Another advantage of using Python is the availability of a community of developers using the same programming language. Python being the most popular programming language, the number of people working on it is high. Since the type of work being done with Python by data scientists are similar, if anyone faces difficulty at any point with their projects it is probable that someone else in the community faced the same problem and has already found a solution. Being part of a community with the most number of people makes it easier to brainstorm solutions. And people working with Python are always helpful.

Data Science is a huge field which requires working with a large number of libraries. Finding the right programming language to master is, therefore, important to work efficiently with all the libraries-

R programming: The only challenge of R is its steep learning curve, but it is an important language for various reasons

• It has a huge open-source community that provides numerous high quality open-source packages for R.
• It boasts of smooth handling of matrix operations and has large statistical functions.
• It has included with it ggplot2 that enables data visualization

Python: With lesser packages than R, Python is still considered to be popular with data scientists. The reasons for that is-

• Libraries like pandas, scikit-learn and tensorflow equip Python to provide most library needs for data science purposes.
• It is very easy to use and operate.
• It has an open-source community that is considered one of the largest one.

SQL: Working on relational databases, Structured Query Language has-

• Readable syntax
• Efficiency in updating, manipulating and querying data for relational databases.

Java: One of the oldest programming languages, Java has limited libraries limiting its potential. Nevertheless it has some advantages.

• Systems coded with Java at the backend makes it easier to integrate data science projects with it making it a compatible option.
• It is a high performance, general purpose, compiled language.

Scala: Working on JVM, it is considered rather complicated. But it does have some advantages-

• Running on JVM, Scala can run on Java as well.
• Used alongside Apache Spark it enables high performance computing cluster.

The following are the steps to downloading Python 3 for Windows:

Download and setup: Go to the download page and setup your python on your windows via GUI installer. While installing, select the checkbox at the bottom asking you to add Python 3.x to PATH, which is your classpath and will allow you to use python’s functionalities from terminal.

Alternatively, you can also install python via Anaconda as well. Check if python is installed by running the following command, you will be shown the version installed:

python --version

• Update and install setuptools and pip: Use below command to install and update 2 of most crucial libraries (3rd party):

python -m pip install -U pip

Note: You can install virtualenv to create isolated python environments and pipenv, which is a python dependency manager.

You can simply install python 3 from their official website through a .dmg package, but we recommend using Homebrew to install python as well as its dependencies. To install python 3 on Mac OS X, just follow the below steps:

• Install xcode: To install brew, you need Apple’s Xcode package, so start with the following 

command and follow through it: $ xcode-select --install

• Install brew: Install Homebrew, a package manager for Apple, using the following command: 

/usr/bin/ruby -e “$(curl -fsS https://raw.githubusercontent.com/Homebrew/install/master/install)”Confirm if it is installed by typing: brew doctor

• Install python 3: To install the latest version of python, use: brew install python
• To confirm its version, use: python --version

You should also install virtualenv, which will help you create isolated places to run different projects and may run even on different python versions.
