Description:

A bare-bones TensorFlow framework for Bayesian deep learning and Gaussian process approximation with stochastic gradient variational Bayes inference.

Some of the features of Aboleth:

  • Bayesian fully-connected, embedding and convolutional layers using SGVB for inference.

  • Random Fourier and arc-cosine features for approximate Gaussian processes. Optional variational optimisation of these feature weights.

  • Imputation layers with parameters that are learned as part of a model.

  • Very flexible construction of networks, e.g. multiple inputs, ResNets etc.

  • Optional maximum-likelihood type II inference for model parameters such as weight priors/regularizers and regression observation noise.

Changes to previous version:

Some moderate changes to the API from:

  • Using TensorFlow's tf.distributions to replace Aboleth's likelihoods
  • Using TensorFlow's tf.distributions to replace Aboleth's distributions
