Published in Towards Data Science·PinnedMember-onlyBayesian Inference — Intuition and Examplewith Python Code — Why did someone have to invent the Bayesian Inference? In one sentence: to update the probability as we gather more data. The core of Bayesian Inference is to combine two different distributions (likelihood and prior) into one “smarter” distribution (posterior). Posterior is “smarter” in the sense that the classic maximum likelihood estimation (MLE) doesn’t take into account a prior…Machine Learning9 min readMachine Learning9 min read
Published in Towards Data Science·PinnedMember-onlyConjugate Prior ExplainedWith examples & proofs — 1. What is Prior? Prior probability is the probability of an event before we see the data. In Bayesian Inference, the prior is our guess about the probability based on what we know now, before new data becomes available. 2. What is Conjugate Prior? Conjugate prior just can not be understood without knowing Bayesian inference.

Why did Poisson have to invent the Poisson Distribution? Why does this distribution exist (= why did he invent this)? When should Poisson be used for modeling? 1. Why did Poisson invent Poisson Distribution? To predict the #…Statistics7 min readStatistics7 min read
Published in Towards Data Science·PinnedMember-onlyBeta Distribution — Intuition, Examples, and DerivationWhen should we use the Beta distribution? — The Beta distribution is a probability distribution on probabilities. It is a versatile probability distribution that could be used to model probabilities in different scenarios. Examples include the Click-Through Rate (CTR) of an advertisement, the conversion rate of customers purchasing on your website, the likelihood of readers clapping for your…Data Science9 min readData Science9 min read
