Chapter 1. Statistics and Probability

The purpose of this chapter is to instill in you the basic concepts of traditional statistics and probability. Certainly many of you might be wondering what it has to do with machine learning. Well, in order to apply a best fit model to your data, the most important prerequisite is for you to understand the data in the first place. This will enable you to find out distributions within data, measure the goodness of data, and run some basic tests to understand if some form of relationship exists between dependant and independent variables. Let’s dive in.

Chapter 2. Regression

Regression and time series analysis make predictions for quantitative target variables possible. This chapter aims to highlight the core concept of regression and its variants. The emphasis here is to take the readers through the journey of model selection when solving for real-world problems. Moreover, this chapter also features statistical tests to evaluate the findings of these regression techniques.

Chapter 3. Time Series

The goal of this chapter is to get you started with time series forecasting. A time series forecast is different from regression in that time acts as an exploratory variable and should be continuous along equal intervals. The chapter will cover the concept of stationary, its importance, and methodologies to check its existence in a time series object. Several time series models will be applied, and their forecasts will be checked using the most effective evaluation techniques.

Chapter 4. Clustering

The goal of this chapter is to solve real-world problems with the aid of supervised and unsupervised learning algorithms. First we will start off with the concept of clustering, determine how to organize the data, decide upon the number of components, and then end up seeing if the cluster outputs make any intuitive sense.

Chapter 5. Classification

This chapter aims to solve real-world problems that depend on a finite number of outcomes. These outcomes can be Boolean in nature, with only two choices (i.e., True/False or Yes/No). They can also be nominal in nature (boat name on which a passenger will embark, maximum education attainment a group of students will have, etc.). Throughout this chapter we will be talking about supervised learning whereby labeled data will be used to train the model. Training the models on this data will enable label predictions on an unseen dataset (i.e., future predictions). In this chapter we will be talking about feature extraction and selection and will conclude with methods to evaluate classification accuracy.
