In previous chapters, we focused on univariate forecasting: predicting one time series from its own historical data. In Chapter 3, we used ARIMA to forecast Google Trends data based solely on its past values. In Chapter 5, we built features from each M5 item-store pair's sales history to predict its future sales. While we trained one model across all 30,490 series, we treated each item-store as conditionally independent, assuming one product's sales don't directly influence another's orders.

That approach, known as univariate ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
