Chapter 10 Learning Probabilistic Model Parameters

Until the early 1990s, the DAG in a Bayesian network was ordinarily hand‐constructed by a domain expert. Then the conditional probabilities were assessed by the expert, learned from data, or obtained using a combination of both techniques. Eliciting Bayesian networks from experts can be a laborious and difficult process in the case of large networks. As a result, researchers developed methods that could learn the DAG from data. Furthermore, they formalized methods for learning the conditional probabilities from data. In a Bayesian network, the conditional probability distributions are called ...

Julian F.

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.
