B) Machine Learning

1. Definition

Machine learning is a branch of the broader field of artificial intelligence that uses statistical models to develop predictions. Often described as a form of predictive modeling or predictive analytics, it has traditionally been defined as the ability of a computer to learn without being explicitly programmed to do so.
In basic technical terms, machine learning uses algorithms that take in empirical or historical data, analyze it, and generate outputs based on that analysis. In some approaches, algorithms first work with so-called "training data" and then learn, predict, and find ways to improve their performance over time.
In one approach, ML systems also learn about data by finding similarities between them and making predictions based on that.
Machine learning is important because it provides businesses with insight into trends in customer behavior and business operating patterns, as well as supports new product development. Many of today's leading companies, such as Facebook, Google and Uber, are making machine learning a central part of their operations.
Machine learning has become a significant competitive element for many companies.

2. Prerequisite and skills

Below are some of the prerequisites for a career in machine learning

Statistics: Statistics contains tools that can be used to get some results from the data. There are descriptive statistics are used to transform raw data into meaningful information. Inferential statistics can also be used to extract important information from a sample of data instead of using the full data set.
Linear algebra: Linear algebra deals with vectors, matrices and linear transformations. It is very important in machine learning because it can be used to transform and perform operations on a dataset.
Calculus: Calculus is an important area in mathematics and plays an integral role in many machine learning algorithms. Multi-feature datasets are used to build machine learning models because the number of multivariate features plays an important role in building a machine learning model. Integration and differentiation are a must.
Probability: Probability helps predict the likelihood of events occurring and helps us reason about whether a situation may or may not happen again. For machine learning, probability is fundamental.
Programming language: To implement the entire process of machine learning, it is essential to know programming languages like R and Python. Both Python and R provide built-in libraries that make implementing machine learning algorithms very easy.

In addition to basic programming knowledge, it is also important that you know how to extract, process and analyze data. This is one of the most important skills required for machine learning.
