Hypernetwork approach to Bayesian MAML

1 code implementation6 Oct 2022 Piotr Borycki, Piotr Kubacki, Marcin Przewięźlikowski, Tomasz Kuśmierczyk, Jacek Tabor, Przemysław Spurek

Unfortunately, previous modifications of MAML are limited due to the simplicity of Gaussian posteriors, MAML-like gradient-based weight updates, or by the same structure enforced for universal and adapted weights.

Reliable Categorical Variational Inference with Mixture of Discrete Normalizing Flows

1 code implementation28 Jun 2020 Tomasz Kuśmierczyk, Arto Klami

Variational approximations are increasingly based on gradient-based optimization of expectations estimated by sampling.

Prior Specification for Bayesian Matrix Factorization via Prior Predictive Matching

2 code implementations27 Oct 2019 Eliezer de Souza da Silva, Tomasz Kuśmierczyk, Marcelo Hartmann, Arto Klami

The behavior of many Bayesian models used in machine learning critically depends on the choice of prior distributions, controlled by some hyperparameters that are typically selected by Bayesian optimization or cross-validation.

Correcting Predictions for Approximate Bayesian Inference

1 code implementation11 Sep 2019 Tomasz Kuśmierczyk, Joseph Sakaya, Arto Klami

Bayesian models quantify uncertainty and facilitate optimal decision-making in downstream applications.
