Surprisingly Strong Performance Prediction with Neural Graph Features

no code implementations25 Apr 2024 Gabriela Kadlecová, Jovita Lukasik, Martin Pilát, Petra Vidnerová, Mahmoud Safari, Roman Neruda, Frank Hutter

Performance prediction has been a key part of the neural architecture search (NAS) process, allowing to speed up NAS algorithms by avoiding resource-consuming network training.

Are Vision Language Models Texture or Shape Biased and Can We Steer Them?

1 code implementation14 Mar 2024 Paul Gavrikov, Jovita Lukasik, Steffen Jung, Robert Geirhos, Bianca Lamm, Muhammad Jehanzeb Mirza, Margret Keuper, Janis Keuper

If text does indeed influence visual biases, this suggests that we may be able to steer visual biases not just through visual input but also through language: a hypothesis that we confirm through extensive experiments.

Smooth Variational Graph Embeddings for Efficient Neural Architecture Search

2 code implementations9 Oct 2020 Jovita Lukasik, David Friede, Arber Zela, Frank Hutter, Margret Keuper

We evaluate the proposed approach on neural architectures defined by the ENAS approach, the NAS-Bench-101 and the NAS-Bench-201 search space and show that our smooth embedding space allows to directly extrapolate the performance prediction to architectures outside the seen domain (e. g. with more operations).

Surrogate NAS Benchmarks: Going Beyond the Limited Search Spaces of Tabular NAS Benchmarks

1 code implementation ICLR 2022 Arber Zela, Julien Siems, Lucas Zimmer, Jovita Lukasik, Margret Keuper, Frank Hutter

We show that surrogate NAS benchmarks can model the true performance of architectures better than tabular benchmarks (at a small fraction of the cost), that they lead to faithful estimates of how well different NAS methods work on the original non-surrogate benchmark, and that they can generate new scientific insight.
