The following figure summarises the notation we’ll use in this article ?:ĭictionary of mathematical expressions and their corresponding English traductions.Īs we have seen in the last post, $P(\text$ has already produced its outcome ($x$). As usual, it is important to ensure that every single piece of mathematical notation is crystal clear. Let’s start with some details about the notation. For instance, we would ask: “If I toss a coin two times, what is the probability to obtain exactly one ‘head’ and one ‘tail’? To answer this kind of questions we need to take into account multiple events. In some cases, it can be interested to see the probabilities of multiple events. In the preceding posts, we have seen the probability of one random variable at a time.

You’ll see that this is an expressive and synthetic way of expressing ideas! We’ll insist on the mathematical notation employed in probability. All of this corresponds to chapters 3.4 and 3.5 of the Deep Learning Book. Then, we will see the concept of conditional probability and the difference between dependent and independent events. In this second post/notebook on marginal and conditional probability you will learn about joint and marginal probability for discrete and continuous variables. The goal was also to gain more intuition for very used tools like derivatives, the area under the curve and integrals. While QM version 2 was used in the 9th edition, POM-QM for Windows Version 3 is now included with all textbooks.

We have learned what is a random variable, a probability mass function or a probability density function. POM-QM for Windows Software Using the full capabilities of Windows, this application gives students a tool to solve quantitative problems. We have studied the basics of probability in the last post/ notebook about chapters 3.1 to 3.3 of the Deep Learning Book. It aims to provide intuitions/drawings/python code on mathematical theories and is constructed as my understanding of these concepts. This content is part of a series following the chapter 3 on probability from the Deep Learning Book by Goodfellow, I., Bengio, Y., and Courville, A.
