Overview of this book

Machine learning makes it possible to learn about the unknowns and gain hidden insights into your datasets by mastering many tools and techniques. This book guides you to do just that in a very compact manner. After giving a quick overview of what machine learning is all about, Machine Learning Quick Reference jumps right into its core algorithms and demonstrates how they can be applied to real-world scenarios. From model evaluation to optimizing their performance, this book will introduce you to the best practices in machine learning. Furthermore, you will also look at the more advanced aspects such as training neural networks and work with different kinds of data, such as text, time-series, and sequential data. Advanced methods and techniques such as causal inference, deep Gaussian processes, and more are also covered. By the end of this book, you will be able to train fast, accurate machine learning models at your fingertips, which you can easily use as a point of reference.

Summary


In this chapter, we learned about time series analysis and white noise. We were introduced to the concepts of random walk, autoregression, autocorrelation, and stationarity, which describes how to figure out whether data is stationary. 

We also learned about differencing, taking the time series data and computing the differences between consecutive observations that lead to the formation of a new series. This chapter also talked about the AR model, which is a part of a stochastic process wherein the specific lagged values of yt are used aspredictor variables and regressed on yin order to estimate the values. We also learned two optimization parameters, namely the AR model and ARIMA model. 

In the next chapter, we will learn about natural language processing.
