AlignNet: Self-supervised Alignment Module

no code implementations25 Sep 2019 Antonia Creswell, Luis Piloto, David Barrett, Kyriacos Nikiforou, David Raposo, Marta Garnelo, Peter Battaglia, Murray Shanahan

The natural world consists of objects that we perceive as persistent in space and time, even though these objects appear, disappear and reappear in our field of view as we move.

Object Question Answering

An Explicitly Relational Neural Network Architecture

2 code implementations ICML 2020 Murray Shanahan, Kyriacos Nikiforou, Antonia Creswell, Christos Kaplanis, David Barrett, Marta Garnelo

With a view to bridging the gap between deep learning and symbolic AI, we present a novel end-to-end neural network architecture that learns to form propositional representations with an explicitly relational structure from raw pixel data.

Relational Reasoning

Learning optimal spike-based representations

no code implementations NeurIPS 2012 Ralph Bourdoukan, David Barrett, Sophie Deneve, Christian K. Machens

We define a loss function for the quality of the population read-out and derive the dynamical equations for both neurons and synapses from the requirement to minimize this loss.
