RELEASE.md
# 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.
