Rigid Body Flows for Sampling Molecular Crystal Structures

Jonas Köhler, Michele Invernizzi, Pim de Haan +1

Normalizing flows (NF) are a class of powerful generative models that have gained popularity in recent years due to their ability to model complex distributions with high flexibili…

Synthesizing Speech from Intracranial Depth Electrodes using an Encoder-Decoder Framework

Jonas Kohler, Maarten C. Ottenhoff, Sophocles Goulis +6

Speech Neuroprostheses have the potential to enable communication for people with dysarthria or anarthria. Recent advances have demonstrated high-quality text decoding and speech s…

This Looks Like That... Does it? Shortcomings of Latent Space Prototype Interpretability in Deep Networks

Adrian Hoffmann, Claudio Fanconi, Rahul Rade +1

Deep neural networks that yield human interpretable decisions by architectural design have lately become an increasingly popular alternative to post hoc interpretation of tradition…

Batch Normalization Provably Avoids Rank Collapse for Randomly Initialised Deep Networks

Hadi Daneshmand, Jonas Kohler, Francis Bach +2

Randomly initialized neural networks are known to become harder to train with increasing depth, unless architectural enhancements like residual connections and batch normalization…

A Sub-sampled Tensor Method for Non-convex Optimization

Aurelien Lucchi, Jonas Kohler

We present a stochastic optimization method that uses a fourth-order regularized model to find local minima of smooth and potentially non-convex objective functions with a finite-s…

Exponential convergence rates for Batch Normalization: The power of length-direction decoupling in non-convex optimization

Jonas Kohler, Hadi Daneshmand, Aurelien Lucchi +3

Normalization techniques such as Batch Normalization have been applied successfully for training deep neural networks. Yet, despite its apparent empirical benefits, the reasons beh…

Escaping Saddles with Stochastic Gradients

Hadi Daneshmand, Jonas Kohler, Aurelien Lucchi +1

We analyze the variance of stochastic gradients along negative curvature directions in certain non-convex machine learning models and show that stochastic gradients exhibit a stron…

Sub-sampled Cubic Regularization for Non-convex Optimization

Jonas Moritz Kohler, Aurelien Lucchi

We consider the minimization of non-convex functions that typically arise in machine learning. Specifically, we focus our attention on a variant of trust region methods known as cu…
