Graph Neural Networks for Learning Equivariant Representations of Neural Networks

1 code implementation18 Mar 2024 Miltiadis Kofinas, Boris Knyazev, Yan Zhang, Yunlu Chen, Gertjan J. Burghouts, Efstratios Gavves, Cees G. M. Snoek, David W. Zhang

Neural networks that process the parameters of other neural networks find applications in domains as diverse as classifying implicit neural representations, generating neural network weights, and predicting generalization errors.

How to Train Neural Field Representations: A Comprehensive Study and Benchmark

1 code implementation16 Dec 2023 Samuele Papa, Riccardo Valperga, David Knigge, Miltiadis Kofinas, Phillip Lippe, Jan-Jakob Sonke, Efstratios Gavves

In this work, we propose $\verb|fit-a-nef|$, a JAX-based library that leverages parallelization to enable fast optimization of large-scale NeF datasets, resulting in a significant speed-up.

Data Augmentations in Deep Weight Spaces

no code implementations15 Nov 2023 Aviv Shamsian, David W. Zhang, Aviv Navon, Yan Zhang, Miltiadis Kofinas, Idan Achituve, Riccardo Valperga, Gertjan J. Burghouts, Efstratios Gavves, Cees G. M. Snoek, Ethan Fetaya, Gal Chechik, Haggai Maron

Learning in weight spaces, where neural networks process the weights of other deep neural networks, has emerged as a promising research direction with applications in various fields, from analyzing and editing neural fields and implicit neural representations, to network pruning and quantization.

Latent Field Discovery In Interacting Dynamical Systems With Neural Fields

1 code implementation NeurIPS 2023 Miltiadis Kofinas, Erik J. Bekkers, Naveen Shankar Nagaraja, Efstratios Gavves

Systems of interacting objects often evolve under the influence of field effects that govern their dynamics, yet previous works have abstracted away from such effects, and assume that systems evolve in a vacuum.

Graph Switching Dynamical Systems

1 code implementation1 Jun 2023 Yongtuo Liu, Sara Magliacane, Miltiadis Kofinas, Efstratios Gavves

Dynamical systems with complex behaviours, e. g. immune system cells interacting with a pathogen, are commonly modelled by splitting the behaviour into different regimes, or modes, each with simpler dynamics, and then learning the switching behaviour from one mode to another.

Roto-translated Local Coordinate Frames For Interacting Dynamical Systems

1 code implementation NeurIPS 2021 Miltiadis Kofinas, Naveen Shankar Nagaraja, Efstratios Gavves

Modelling interactions is critical in learning complex dynamical systems, namely systems of interacting objects with highly non-linear and time-dependent behaviour.
