Minimum Description Length Control

no code implementations17 Jul 2022 Ted Moskovitz, Ta-Chu Kao, Maneesh Sahani, Matthew M. Botvinick

We propose a novel framework for multitask reinforcement learning based on the minimum description length (MDL) principle.

Bayesian Inference Continuous Control +2

Scalable Bayesian GPFA with automatic relevance determination and discrete noise models

no code implementations NeurIPS 2021 Kristopher Jensen, Ta-Chu Kao, Jasmine Stone, Guillaume Hennequin

We apply bGPFA to continuous recordings spanning 30 minutes with over 14 million data points from primate motor and somatosensory cortices during a self-paced reaching task.

iLQR-VAE : control-based learning of input-driven dynamics with applications to neural data

no code implementations ICLR 2022 Marine Schimel, Ta-Chu Kao, Kristopher T Jensen, Guillaume Hennequin

To achieve this, a common approach is to record neural populations in behaving animals, and model these data as emanating from a latent dynamical system whose state trajectories can then be related back to behavioural observations via some form of decoding.

Model Optimization Variational Inference

Natural continual learning: success is a journey, not (just) a destination

1 code implementation NeurIPS 2021 Ta-Chu Kao, Kristopher T. Jensen, Gido M. van de Ven, Alberto Bernacchia, Guillaume Hennequin

In contrast, artificial agents are prone to 'catastrophic forgetting' whereby performance on previous tasks deteriorates rapidly as new ones are acquired.

Continual Learning

Automatic differentiation of Sylvester, Lyapunov, and algebraic Riccati equations

1 code implementation23 Nov 2020 Ta-Chu Kao, Guillaume Hennequin

Sylvester, Lyapunov, and algebraic Riccati equations are the bread and butter of control theorists.

Manifold GPLVMs for discovering non-Euclidean latent structure in neural data

1 code implementation NeurIPS 2020 Kristopher T. Jensen, Ta-Chu Kao, Marco Tripodi, Guillaume Hennequin

A common problem in neuroscience is to elucidate the collective neural representations of behaviorally important variables such as head direction, spatial location, upcoming movements, or mental spatial transformations.
