Description:
Each lecture requires 2 hrs; 12 lectures + 4 labs = 36 hours (7 weeks: 19/10 - 4/12)
- The multivariate Gaussian distribution: conditionals, marginals, and conjugate prior (and its problems)
- Laplace method and Fisher matrix
- Linear/ Gaussian models: probabilistic PCA and linear regression. Basis function regression.
- Gaussian processes for regression and Bayesian Optimization.
- Lab 1: linear regression and Gaussian Processes
- Bayesian inference in non-conjugate models: Markov Chain Monte Carlo (MCMC), rejection and importance sampling, Metropolis-Hastings algorithm. Convergence diagnostics and rules of thumb.
- Generalised linear models (GLMs) and inference; Gaussian processes for classification.
- Lab 2: Bayesian GLMs.
- Graphical models and hierarchical Bayesian models. Gibbs sampling.
- Mixture models and topic models.
- Variable augmentation: probit and logistic regression with auxiliary variables
- Lab 3: Gibbs sampling for mixture models.
- Variational inference: prelude, the EM algorithm
- Mean-field variational inference
- Variational inference for general models: black-box variational inference and variational autoencoders, Stein variational inference.
- Lab 4: Variational mean field for mixture models.
