a6f3043 Merge branch 'develop-2.0' of github.com:GPflow/GPflow into develop-2.0 27 October 2019, 17:21:33 UTC
5d6336f GPflow 2.0 notebook update: SGPR upper bound (#1116) This PR updates the understanding/upper_bound.ipynb to work in gpflow2. It fixes the upper_bound code in gpflow/models/sgpr.py and restores the original (tighter) test tolerance that had both been changed by commit 45efebc The plots don't quite match up to what was in the GPflow1 version (nor does the tight bound in the 1-inducing-point example at the end), but otherwise this seems to work. 27 October 2019, 16:46:49 UTC

d048736 Change GPflow 2.0 scipy default method to L-BFGS-B (as in GPflow 1.0) (#1112) Explicitly sets the default optimization method for Scipy() to L-BFGS-B (as in gpflow1), instead of letting scipy.minimize() figure it out. This resulted in BFGS, which may be too aggressive when encountering complex optimization surfaces, so L-BFGS-B may be a more sensible default. 27 October 2019, 16:28:49 UTC

330074a GPflow 2.0 notebook update: FITC vs VFE (#1104) * WIP * make it run * rerun notebook * rerun notebook after merging in bugfix * Call step_callback through scipy.minimize's callback procedure (at the end of each step); previous behaviour was to call step_callback at each evaluation of objective function * adjust callback signature * changes to make it work under gpflow2: method=L-BFGS-B, tol=1e-11. increase callback frequency * rerun notebook * remove from notebook test blacklist * fix Scipy 23 October 2019, 10:16:51 UTC
6e43fec Change step_callback behaviour of Scipy optimizer in gpflow2 to behave as in gpflow1 (#1111) Changes behaviour of step_callback so that the callback only gets called once per optimisation step, not once per objective function evaluation. Makes gpflow2's Scipy() behave more like gpflow1's ScipyOptimizer()/monitoring. * Call step_callback through scipy.minimize's callback procedure (at the end of each step); previous behaviour was to call step_callback at each evaluation of objective function * split off from unpack_tensors (now stateless) the new assign_tensors (assigns to variables) * change callback_func to pass variables and their current values to step_callback, not assigning/computing loss/gradients * fix type signature * Improve docstring 22 October 2019, 16:54:27 UTC

b0ddc6d Notebook for Variational Fourier Features (#1062) Adds a notebook that demonstrates how to add inter-domain inducing variables to GPflow without having to touch the core code base, at the example of variational Fourier features (Hensman, Durrande, Solin, JMLR 18 (2018)). 21 October 2019, 14:19:32 UTC
33ded03 Ensure all tf_probability distributions take the correct dtype parameters (#1103) 18 October 2019, 15:06:01 UTC
deb4508 Fix hidden bug in SGPR (#1106) 1. Fix hidden bug in SGPR 2. Add the sgpr.compute_qu method from gpflow1 1. [Bug]. SGPR likelihoods were previously using full rank matrices instead of diagonal ones in both upper bound and likelihood calculation. Ie `Kdiag` was not "diag". This error was being masked by the intentional deactivation of tests comparing to the SGPR to the GPR, and what appears to be a hack to make tests working on the upper bound case. 2. [Migration]. Fixing the above broke another test, originally used for sgpr.compute_qu. The method sgpr.compute_qu had not been migrated from gpflow1, and a test that was meant to check it had been patched up to pass, erroneously. After speaking to @markvdw, concluded this method is useful, in particular to compare to SVGP model. The test has been patched up and the method ported to gpflow2. 17 October 2019, 14:46:42 UTC
3b2a2ee Change gpflow.base.Module attributes `parameter` and `trainable parameter` to be wrapped in a tuple, not generators (#1102) This matches tf2 behaviour [here](https://github.com/tensorflow/tensorflow/blob/1cf0898dd4331baf93fe77205550f2c2e6c90ee5/tensorflow/python/module/module.py#L143) and prevents accidentally trying to reuse the same the generator once exhausted. 16 October 2019, 09:39:04 UTC

4aef40d fix bug in log_prior when a Parameter has a transform but no prior (#1099) Fixes a bug in the optimization objective for all `BayesianModel` subclasses when the model has parameters that have a `transform` (e.g. `positive()`, for kernel lengthscales and variances) but no `prior` (i.e. when doing Maximum Likelihood Estimation (MLE) inference). The objective should be independent of the parametrisation of the parameters, i.e. `log_prior()` of the parameters should be zero. 14 October 2019, 21:36:48 UTC
