Aligned and oblique dynamics in recurrent neural networks

Friedrich Schuessler, Francesca Mastrogiuseppe, Srdjan Ostojic +1

The relation between neural activity and behaviorally relevant variables is at the heart of neuroscience research. When strong, this relation is termed a neural representation. The…

Charting and navigating the space of solutions for recurrent neural networks

Elia Turner, Kabir Dabholkar, Omri Barak

Recurrent Neural Networks (RNNs) were recently successfully used to model the way neural activity drives task-related behavior in animals, operating under the implicit assumption t…

Cancer Progression as a Learning Process

Aseel Shomar, Omri Barak, Naama Brenner

Drug resistance and metastasis - the major complications in cancer - both entail adaptation of cancer cells to stress, whether a drug or a lethal new environment. Intriguingly, the…

Quality of internal representation shapes learning performance in feedback neural networks

Lee Susman, Francesca Mastrogiuseppe, Naama Brenner +1

A fundamental feature of complex biological systems is the ability to form feedback interactions with their environment. A prominent model for studying such interactions is reservo…

Mapping low-dimensional dynamics to high-dimensional neural activity: A derivation of the ring model from the neural engineering framework

Omri Barak, Sandro Romani

Empirical estimates of the dimensionality of neural population activity are often much lower than the population size. Similar phenomena are also observed in trained and designed n…

Implementing Inductive bias for different navigation tasks through diverse RNN attractors

Tie Xu, Omri Barak

Navigation is crucial for animal behavior and is assumed to require an internal representation of the external environment, termed a cognitive map. The precise form of this represe…

Dynamics of random recurrent networks with correlated low-rank structure

Friedrich Schuessler, Alexis Dubreuil, Francesca Mastrogiuseppe +2

A given neural network in the brain is involved in many different tasks. This implies that, when considering a specific task, the network's connectivity contains a component which…
