BrainSLAM: SLAM on Neural Population Activity Data

no code implementations1 Feb 2024 Kipp Freud, Nathan Lepora, Matt W. Jones, Cian O'Donnell

This system uses a convolutional neural network (CNN) to decode velocity and familiarity information from wavelet scalograms of neural local field potential data recorded from rats as they navigate a 2D maze.

Signatures of Bayesian inference emerge from energy efficient synapses

1 code implementation6 Sep 2023 James Malkin, Cian O'Donnell, Conor Houghton, Laurence Aitchison

The resulting networks revealed a tradeoff between circuit performance and the energetic cost of synaptic reliability.

Nonlinear slow-timescale mechanisms in synaptic plasticity

no code implementations13 Jun 2023 Cian O'Donnell

Learning and memory relies on synapses changing their strengths in response to neural activity.

Adaptive Estimators Show Information Compression in Deep Neural Networks

no code implementations ICLR 2019 Ivan Chelombiev, Conor Houghton, Cian O'Donnell

With two improved methods of estimation, firstly, we show that saturation of the activation function is not required for compression, and the amount of compression varies between different activation functions.
