Categorical Distribution & Indicator Function | Intro | with TensorFlow Probability

An introduction to the Categorical with a simple tutorial in TensorFlow Probability. Here are the notes: https://raw.githubusercontent.com/Ceyron/machine-learning-and-simulation/main/english/essential_pmf_pdf/categorical_intro.pdf

The Bernoulli Distribution allowed us to model discrete random variables with only two states (think of the weather, which can either be good or bad). Often, we, however, want to model discrete variables with more than two states, maybe even multiple hundred. That is where the generalization of the Bernoulli, the Categorical, comes in. In this video, we look at how to define such a kind of distribution and how to use it in TensorFlow Probability.
