This library implements various Bayesian linear models (Bayesian linear regression) and generalised linear models. A few features of this library are:

  • A fancy basis functions/feature composition framework for combining basis functions like radial basis function, sigmoidal basis functions, polynomial basis functions etc.

  • Basis functions that can be used to approximate Gaussian processes with shift invariant covariance functions (e.g. square exponential) when used with linear models [1], [2], [3].

  • Non-Gaussian likelihoods with Bayesian generalised linear models using a modified version of the nonparametric variational inference algorithm presented in [4].

  • Large scale learning using stochastic gradient descent (ADADELTA).

Changes to previous version:
  • Partial application of basis functions
  • Bayesian GLM fully implemented with SGD
  • library refactor and removal of functionality that is also in sklearn
  • Many bug fixes and much more thorough unit testing
