Overview of this book

We live in a serendipitous era where the explosion in the quantum of data collected and a renewed interest in data-driven techniques such as machine learning (ML), has changed the landscape of analytics, and with it, time series forecasting. This book, filled with industry-tested tips and tricks, takes you beyond commonly used classical statistical methods such as ARIMA and introduces to you the latest techniques from the world of ML. This is a comprehensive guide to analyzing, visualizing, and creating state-of-the-art forecasting systems, complete with common topics such as ML and deep learning (DL) as well as rarely touched-upon topics such as global forecasting models, cross-validation strategies, and forecast metrics. You’ll begin by exploring the basics of data handling, data visualization, and classical statistical methods before moving on to ML and DL models for time series forecasting. This book takes you on a hands-on journey in which you’ll develop state-of-the-art ML (linear regression to gradient-boosted trees) and DL (feed-forward neural networks, LSTMs, and transformers) models on a real-world dataset along with exploring practical topics such as interpretability. By the end of this book, you’ll be able to build world-class time series forecasting systems and tackle problems in the real world.

Setting a Strong Baseline Forecast

In the previous chapter, we saw some techniques we can use to understand time series data, do some Exploratory Data Analysis (EDA), and so on. But now, let’s get to the crux of the matter – time series forecasting. The point of understanding the dataset and looking at patterns, seasonality, and so on was to make the job of forecasting that series easier. And with any machine learning exercise, one of the first things we need to establish before going further is a baseline.

A baseline is a simple model that provides reasonable results without requiring a lot of time to come up with them. Many people think of baselines as something that is derived from common sense, such as an average or some rule of thumb. But as a best practice, a baseline can be as sophisticated as we want it to be, so long as it is quickly and easily implemented. Any further progress we want to make will be in terms of the performance of this baseline.
