Variational Stochastic Gradient Descent for Deep Neural Networks

1 code implementation9 Apr 2024 Haotian Chen, Anna Kuzina, Babak Esmaeili, Jakub M Tomczak

We model gradient updates as a probabilistic model and utilize stochastic variational inference (SVI) to derive an efficient and effective update rule.

Discouraging posterior collapse in hierarchical Variational Autoencoders using context

1 code implementation20 Feb 2023 Anna Kuzina, Jakub M. Tomczak

Hierarchical Variational Autoencoders (VAEs) are among the most popular likelihood-based generative models.

Equivariant Priors for Compressed Sensing with Unknown Orientation

no code implementations28 Jun 2022 Anna Kuzina, Kumar Pratik, Fabio Valerio Massoli, Arash Behboodi

In compressed sensing, the goal is to reconstruct the signal from an underdetermined system of linear measurements.

On Analyzing Generative and Denoising Capabilities of Diffusion-based Deep Generative Models

1 code implementation31 May 2022 Kamil Deja, Anna Kuzina, Tomasz Trzciński, Jakub M. Tomczak

Their main strength comes from their unique setup in which a model (the backward diffusion process) is trained to reverse the forward diffusion process, which gradually adds noise to the input signal.
