We can use Bayes’ theorem to update our hypothesis when new evidence comes to light. For example, given some data D which contains the one d_1data point, then our posterior is: Lets say we now acquire another data point d_2, so we have more evidence to evaluate and update our belief (posterior) on. … See more In my previous article we derived Bayes’ theorem from conditional probability. If you are unfamiliar with Bayes’ theorem, I highly recommend reading that article before carrying on … See more We can write Bayes’ theorem as follows: 1. P(H) is the probability of our hypothesis which is the prior. This is how likely our hypothesis is before we see our evidence/data. 2. P(D H) is the likelihood, which is the … See more In this article we have shown how you can use Bayes’ theorem to update your beliefs when you are presented with new data.
