Before any formula, Bayesian inference is a way of reasoning: hold beliefs as probabilities, and revise them in proportion to the evidence. This chapter sets up that worldview — probability as degree of belief, the contr

Now we make the update rule exact. Bayes' theorem is a short consequence of the definition of conditional probability, but its implications are deep enough to have reshaped statistics, science, and AI. This chapter deriv

In Chapters – the hypotheses were discrete (sick or healthy). The real power of Bayesian inference appears when the unknown is a continuous parameter — a probability, a rate, a mean — so the prior and posterior become di
Leggi l'articolo →Conjugate Priors and Updating
Computing the posterior means doing the integral p(D)= p(D )p( ) d — usually hard. Conjugate priors are a beautiful special case where the integral is free: prior and posterior belong to the same family, so updating is j
Leggi l'articolo →Choosing Priors
The prior is what makes Bayesian inference both powerful and controversial: it lets you inject knowledge, but it also forces you to be explicit about your assumptions. This chapter is a practical guide to choosing priors

The posterior is a full distribution, but people need answers: a single estimate, an interval, a yes/no decision. This chapter shows how to summarize a posterior responsibly (point estimates and credible intervals) and h

Real problems have many interacting variables. Bayesian networks (directed graphical models) make such joint distributions tractable by drawing the dependencies as a graph: an arrow means “directly influences,” a missing

Conjugacy is a luxury; most real posteriors have no closed form because the evidence integral p(D)= p(D )p( ) d is intractable. The modern Bayesian toolkit sidesteps it two ways: MCMC draws samples from the posterior wit

Now we put the machinery to work on the models practitioners use every day. Bayesian regression replaces point-estimate coefficients with full posteriors, delivering principled uncertainty on every prediction. Hierarchic

Inference within a model assumes the model is right. But which model should we use? Bayesian model comparison answers this with the very quantity we worked so hard to avoid — the evidence p(D) — which turns out to automa

This capstone gathers the threads into one claim: Bayesian reasoning is the theory of learning under uncertainty, and it quietly underwrites much of machine learning. The loss is a likelihood. Regularization is a prior.

Calculus studies how things change and how things accumulate. Before we can speak of change, we need the object that changes: the function. This chapter sets up functions and the handful of “essential” ones that appear e

The limit is the idea that makes calculus rigorous. “Instantaneous” rate of change and “infinitely thin” rectangles both hide a limit: a quantity we approach but may never reach. This chapter builds limits intuitively an
