Release 0.3.5

  • Update to work with TensorFlow 0.12.1.

Release 0.3.4

  • Changes to stop computations all being done on the default graph.
  • Update list of GPflow contributors and other small changes to front page.
  • Better deduction of input_dim for kernels.Combination
  • Some kernels did not properly respect active dims, now fixed.
  • Make sure log jacobian is computed even for fixed variables

Release 0.3.3

  • House keeping changes for paper submission.

Release 0.3.2

  • updated to work with tensorflow 0.11 (release candidate 1 available at time of writing)
  • bugfixes in vgp._compile

Release 0.3.1

  • Added configuration file, which controls verbosity and level of numerical jitter
  • tf_hacks is deprecated, became tf_wraps (tf_hacks will raise visible deprecation warnings)
  • Documentation now at gpflow.readthedocs.io
  • Many functions are now contained in tensorflow scopes for easier tensorboad visualisation and profiling

Release 0.3

  • Improvements to the way that parameters for triangular matrices are stored and optimised.
  • Automatically generated Apache license headers.
  • Ability to track log probabilities.

Release 0.2

  • Significant improvements to the way that data and fixed parameters are handled.

Previously, data and fixed parameters were treated as tensorflow constants. Now, a new mechanism called get_feed_dict() can gather up data and and fixed parameters and pass them into the graph as placeholders.

  • To enable the above, data are now stored in objects called DataHolder. To access values of the data, use the same syntax as parameters: print(m.X.value)

  • Models do not need to be recompiled when the data changes.

  • Two models, VGP and GPMC, do need to be recompiled if the shape of the data changes

  • A multi-class likelihood is implemented

Release 0.1.4

  • Updated to work with tensorflow 0.9
  • Added a Logistic transform to enable contraining a parameter between two bounds
  • Added a Laplace distribution to use as a prior
  • Added a periodic kernel
  • Several improvements to the AutoFlow mechanism
  • added FITC approximation (see comparison notebook)
  • improved readability of code according to pep8
  • significantly improved the speed of the test suite
  • allowed passing of the 'tol' argument to scipy.minimize routine
  • added ability to add and multiply MeanFunction objects
  • Several new contributors (see README.md)

Release 0.1.3

  • Removed the need for a fork of TensorFlow. Some of our bespoke ops are replaced by equivalent versions.

Release 0.1.2

  • Included the ability to compute the full covaraince matrix at predict time. See GPModel.predict_f
  • Included the ability to sample from the posterior function values. See GPModel.predict_f_samples
  • Unified code in conditionals.py: see deprecations in gp_predict, etc.
  • Added SGPR method (Sparse GP Regression)

Release 0.1.1

  • included the ability to use tensorflow's optimizers as well as the scipy ones

Release 0.1.0

The initial release of GPflow.
