Introduction to Bayes' Theorem

Bayes' Theorem calculates the probability of an event based on prior knowledge of conditions related to the event. It's foundational in machine learning for updating beliefs upon receiving new data.Bayesian Inference Explained

Bayesian inference uses Bayes' Theorem to update the probability estimate for a hypothesis as more evidence becomes available. It contrasts with frequentist inference that relies on sampling distributions.Bayesian Machine Learning

In machine learning, Bayesian methods enable robust probabilistic modeling. They excel in uncertainty estimation, crucial for fields like medicine, where decision-making involves significant risks.Bayesian vs. Frequentist

Bayesian approaches consider probabilities as beliefs, not frequencies. This perspective allows incorporating prior knowledge and evidential updates, unlike frequentist methods that interpret probabilities strictly from long-run frequencies.Bayes in Spam Filtering

A practical application of Bayes' Theorem is in spam filtering. Machine learning models calculate the probability of an email being spam, adapting over time with each new piece of information.Advanced: Gibbs Sampling

Gibbs sampling, a Markov Chain Monte Carlo algorithm, enables sampling from complex distributions. It's used in Bayesian machine learning to approximate the posterior distribution when direct computation is intractable.Surprising Bayesian Networks

Bayesian networks, a type of graphical model, represent variables and their conditional dependencies. Surprisingly, they can deduce the probabilistic relationships between unknown variables in large, complex datasets.What does Bayes' Theorem calculate?
