b41d4f3 | st-- | 23 April 2020, 18:17:42 UTC | refactor natgrads to be more efficient (#1443) Previously, GPflow's NaturalGradient optimizer would call the loss_function once for each (q_mu, q_sqrt) set in the var_list. This is a light refactor that separates out applying the natural gradient step from computing the gradients (`_natgrad_apply_gradients`), and changes `_natgrad_steps` to only evaluate the loss function once, computing the gradients for all (q_mu, q_sqrt) tuples passed in the var_list. Other changes: - The no-longer-used `_natgrad_step` method got removed. - NaturalGradient now takes a `xi_transform` argument that is used for all parameter sets without explicitly specified xi transform (i.e. tuples rather than triplets). - XiTransform has been changed to have staticmethods. None of this should affect any downstream code; this PR is backwards-compatible. | 23 April 2020, 18:17:42 UTC |

7e717cc | st-- | 31 March 2020, 12:17:12 UTC | refactor training objective methods (#1276) This gives all `BayesianModel` subclasses a consistent interface both for optimization (MLE/MAP) and MCMC. Models are required to implement `maximum_log_likelihood_objective`, which is to be maximized for model training. Optimization: The `_training_loss` method is defined as `- (maximum_log_likelihood_objective + log_prior_density)`. This is exposed by the InternalDataTrainingLossMixin and ExternalDataTrainingLossMixin classes. For models that keep hold of the data internally, `training_loss` can directly be passed as a closure to an optimizer's `minimize`, for example: ```python model = gpflow.models.GPR(data, ...) gpflow.optimizers.Scipy().minimize(model.training_loss, model.trainable_variables) ``` If the model objective requires data to be passed in, a closure can be constructed on the fly using `model.training_loss_closure(data)`, which returns a no-argument closure: ```python model = gpflow.models.SVGP(...) gpflow.optimizers.Scipy().minimize( model.training_loss_closure(data), model.trainable_variables, ... ) ``` The training_loss_closure() method provided by both InternalDataTrainingLossMixin and ExternalDataTrainingLossMixin takes a boolean `compile` argument (default: True) that wraps the returned closure in tf.function(). Note that the return value should be cached in a variable if the minimize() step is run several times to avoid re-compilation in each step! MCMC: The `log_posterior_density` method can be directly passed to the `SamplingHelper`. By default, `log_posterior_density` is implemented as `maximum_log_likelihood_objective + log_prior_density`. Models can override this if needed. Example: ```python model = gpflow.models.GPMC(...) hmc_helper = gpflow.optimizers.SamplingHelper( model.log_posterior_density, model.trainable_parameters ) hmc = tfp.mcmc.HamiltonianMonteCarlo( target_log_prob_fn=hmc_helper.target_log_prob_fn, ... ) ``` In this case, the function that runs the MCMC chain should be wrapped in tf.function() (see MCMC notebook). | 31 March 2020, 12:17:12 UTC |

72de787 | joelberkeley-pio | 30 March 2020, 17:58:43 UTC | rename jit to compile (#1392) | 30 March 2020, 17:58:43 UTC |
1e936e0 | Mark van der Wilk | 30 March 2020, 12:08:03 UTC | Increased tolerance for sqrt in kernels K_r2. (#1388) We had a report of numerical problems when the tolerance was 1e-40. So in GPflow 1 it got changed to 1e-36, but this wasn't ported to GPflow 2, hence why we're fixing it now. | 30 March 2020, 12:08:03 UTC |
792201d | Mark van der Wilk | 30 March 2020, 11:35:07 UTC | Added suggestion on how to open TensorBoard so it updates. (#1389) | 30 March 2020, 11:35:07 UTC |
c8e8f00 | ilia-kats | 30 March 2020, 11:20:14 UTC | enable pickling of frozen models (#1338) Changes setattr_by_path to delete the attribute before setting it again. When simply replacing a Parameter with tf.Constant, tensorflow did not update its internal list of tracked variables, which prevented deepcopying and pickling of frozen models. Explicitly deleting the tracked variable before assigning a constant value forces tensorflow to update its state. Workaround for https://github.com/tensorflow/tensorflow/issues/37806 | 30 March 2020, 11:20:14 UTC |
0b9e1f0 | st-- | 30 March 2020, 11:17:24 UTC | MCMC cleanup (#1374) * SamplingHelper: clean up docstrings * SamplingHelper: do not convert to numpy in convert_to_constrained_samples * MCMC notebook: clean up; make faster (ci_niter); remove opaque use of utility function * MCMC notebook: clarify MCMC over Z for SGPMC - inducing points should be non-trainable * tests: use pytest.raises * tests: clean up match argument | 30 March 2020, 11:17:24 UTC |

aff62bc | st-- | 30 March 2020, 09:32:58 UTC | Make Scipy more robust & faster (#1377) * Adds an explicit check to Scipy() that all elements of `variables` are actually tf.Variable instances (unconstrained variables) - accidentally passing `model.trainable_parameters` may work but give the wrong answers for parameters with transforms! Passing `model.trainable_variables` is the right thing to do. * Updates _compute_loss_and_gradients to only compute gradients wrt passed-in variables. * Fix mixture density network notebook, which had erroneously passed model.trainable_parameters instead of model.trainable_variables. | 30 March 2020, 09:32:58 UTC |
d41d6eb | Vincent Dutordoir | 30 March 2020, 08:49:58 UTC | Set kernelspec to Py3 in monitoring.pct.py (#1386) Quickfix for the failing monitoring.pct.py notebook during the doc generation on CircleCi. Problem was caused by an unknown Python version in the notebook's kernelspec. It has to be 'name: python3', whereas conda may add a user-specific custom name there. | 30 March 2020, 08:49:58 UTC |
82999c9 | st-- | 30 March 2020, 08:47:02 UTC | minimum required multipledispatch version is 0.6 (#1384) As shown by #1381, gpflow does not work with older versions of multipledispatch - this change reflects this in the setup.py version requirements. | 30 March 2020, 08:47:02 UTC |

cf35758 | Eric Hammy | 27 March 2020, 15:23:42 UTC | moved multioutput module files (#1353) Moved all `mo_` files to be in their own multioutput directory. This should be more sustainable as the number of multioutput items increases | 27 March 2020, 15:23:42 UTC |

8d0128c | ilia-kats | 26 March 2020, 21:02:24 UTC | fix Cosine kernel for multivariate inputs (#1357) The previous version operating on Euclidean distance was returning indefinite covariance matrices on multivariate data. This version, derived from eq. 4.7 of Wilson (2014), is always positive semidefinite. Closes #1328. This PR also changes the definition of the cosine kernel slightly, from sigma * cos(|x - x'| / l) to sigma * cos(2 * pi * (x - x') / l). This makes the lengthscale parameter directly interpretable as period length. It introduces new IsotropicStationary and AnisotropicStationary base classes. | 26 March 2020, 21:02:24 UTC |

118dcfe | joshuacoales-pio | 26 March 2020, 16:46:56 UTC | Fixing up broken notebook links (#1369) Fixing broken notebook links in the README, GPFlow intro, and gpflow2 upgrade guide. Mostly links to files which used to be .ipynb jupyter files, and are now jupytext files. Removing (commenting out) a couple links to now-removed notebooks. Updating link to monitoring notebook, such that #1344 just needs to uncomment that line | 26 March 2020, 16:46:56 UTC |
