Another way to avoid overcounting would be to use the buffer for updating the linearization point without updating mu or sigma. For example, at the beginning of step t we...

Translate this theano/pymc code into blackjax https://github.com/TeaPearce/Expressive_Priors_in_BNNs/blob/master/code/timeseries_hmc_05.py This should reproduce fig 3 from te paper below (first 3 columns, ignore the GP part) T. Pearce, R. Tsuchida, M. Zaki, A....

The [API for build_xxx_kernel](https://github.com/jeremiecoullon/SGMCMCJax/blob/master/sgmcmcjax/kernels.py) has the form ``` build_kernel(varargs, loglikelihood, logprior, data, batch_size, kwargs) ``` where varargs is a variable number of arguments, depending on the kernel. For example ```...

- In examples/gmrf.ipynb, maybe replace `from jax.example_libraries import optimizers` with optax. Also the term "GMRF" usually refers to Gaussian MRF, not grid :) Finally the learning code is super slow,...

I added a very short new section on training objectives for deep generative models, going beyond the likelihood maximization approach adopted in most of the book. This is motivated by...

Computing the log parition function for a conjugate family is a very useful quantity eg for computing the marginal likelihood p(D), which is needed for empirical Bayes and model selection....

Objective should be max \sum_i ||z_i||^2 s.t. || z_i - z_j || = || x_i - x_j || for neighbors. This would give max Tr(K) s.t. K_ii _+ K_jj -...
