Implicit Processes (IPs) can be used as a flexible framework to describe a wide variety of models, ranging from Bayesian neural networks to neural samplers, normalizing flows and many others. IPs also allow for approximate inference in function-space, and this formulation solves intrinsic degenerate problems of regular parameter-space approximate Bayesian inference. These issues concern the high number of parameters and their strong dependencies in large models. Because of this, previous works in the literature have attempted to employ IPs both to set up the prior and to approximate the resulting posterior. However, this has proven to be a challenging task, being unable to both (i) tune the prior IP parameters according to data, and (ii) produce flexible predictive distributions (mostly restricted to be Gaussian). We will study previous contributions and showcase some new ideas included in our recently proposed method, which can accomplish both goals simultaneously for the first time.

After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
