Eureka-Moments in Transformers: Multi-Step Tasks Reveal Softmax Induced Optimization Problems

no code implementations19 Oct 2023 David T. Hoffmann, Simon Schrodi, Nadine Behrmann, Volker Fischer, Thomas Brox

In this work, we study rapid, step-wise improvements of the loss in transformers when being confronted with multi-step decision tasks.

Unified Fully and Timestamp Supervised Temporal Action Segmentation via Sequence to Sequence Translation

2 code implementations1 Sep 2022 Nadine Behrmann, S. Alireza Golestaneh, Zico Kolter, Juergen Gall, Mehdi Noroozi

This paper introduces a unified framework for video action segmentation via sequence to sequence (seq2seq) translation in a fully and timestamp supervised setup.

Ranking Info Noise Contrastive Estimation: Boosting Contrastive Learning via Ranked Positives

1 code implementation27 Jan 2022 David T. Hoffmann, Nadine Behrmann, Juergen Gall, Thomas Brox, Mehdi Noroozi

This paper introduces Ranking Info Noise Contrastive Estimation (RINCE), a new member in the family of InfoNCE losses that preserves a ranked ordering of positive samples.

Long Short View Feature Decomposition via Contrastive Video Representation Learning

no code implementations ICCV 2021 Nadine Behrmann, Mohsen Fayyaz, Juergen Gall, Mehdi Noroozi

We argue that a single representation to capture both types of features is sub-optimal, and propose to decompose the representation space into stationary and non-stationary features via contrastive learning from long and short views, i. e. long video sequences and their shorter sub-sequences.

Meta-Learning Runge-Kutta

no code implementations25 Sep 2019 Nadine Behrmann, Patrick Schramowski, Kristian Kersting

However, by studying the characteristics of the local error function we show that including the partial derivatives of the initial value problem is favorable.
