The underlying structures of self-attention: symmetry, directionality, and emergent dynamics in Transformer training

1 code implementation15 Feb 2025 Matteo Saponati, Pascal Sager, Pau Vilimelis Aceituno, Thilo Stadelmann, Benjamin Grewe

Self-attention is essential to Transformer architectures, yet how information is embedded in the self-attention matrices and how different objective functions impact this process remains unclear.

The Role of Temporal Hierarchy in Spiking Neural Networks

no code implementations26 Jul 2024 Filippo Moro, Pau Vilimelis Aceituno, Laura Kriener, Melika Payvand

The temporal dynamics such as time constants of the synapses and neurons and delays have been recently shown to have computational benefits that help reduce the overall number of parameters required in the network and increase the accuracy of the SNNs in solving temporal tasks.

Two types of pyramidal cells and their role in temporal processing

no code implementations12 Dec 2023 Anh Duong Vo, Elisabeth Abs, Pau Vilimelis Aceituno, Benjamin Friedrich Grewe, Katharina Anna Wilmes

Recent work has provided new insights into the temporal specialization of Intratelencephalic (IT) and Pyramidal tract neurons (PT).

Bio-Inspired, Task-Free Continual Learning through Activity Regularization

no code implementations8 Dec 2022 Francesco Lässig, Pau Vilimelis Aceituno, Martino Sorbaro, Benjamin F. Grewe

We evaluate the new sparse-recurrent version of DFC on the split-MNIST computer vision benchmark and show that only the combination of sparsity and intra-layer recurrent connections improves CL performance with respect to standard backpropagation.

Disentangling the Predictive Variance of Deep Ensembles through the Neural Tangent Kernel

no code implementations18 Oct 2022 Seijin Kobayashi, Pau Vilimelis Aceituno, Johannes von Oswald

Identifying unfamiliar inputs, also known as out-of-distribution (OOD) detection, is a crucial property of any decision making process.

Credit Assignment in Neural Networks through Deep Feedback Control

3 code implementations NeurIPS 2021 Alexander Meulemans, Matilde Tristany Farinha, Javier García Ordóñez, Pau Vilimelis Aceituno, João Sacramento, Benjamin F. Grewe

The success of deep learning sparked interest in whether the brain learns by using similar techniques for assigning credit to each synaptic weight for its contribution to the network output.

Tailoring Artificial Neural Networks for Optimal Learning

1 code implementation8 Jul 2017 Pau Vilimelis Aceituno, Yan Gang, Yang-Yu Liu

As one of the most important paradigms of recurrent neural networks, the echo state network (ESN) has been applied to a wide range of fields, from robotics to medicine, finance, and language processing.
