Grid Cell Path Integration For Movement-Based Visual Object Recognition
Niels Leadholm, Marcus Lewis, Subutai Ahmad
Grid cells enable the brain to model the physical space of the world and navigate effectively via path integration, updating self-position using information from self-movement. Rec…
Long Distance Relationships without Time Travel: Boosting the Performance of a Sparse Predictive Autoencoder in Sequence Modeling
Jeremy Gordon, David Rawlinson, Subutai Ahmad
In sequence learning tasks such as language modelling, Recurrent Neural Networks must learn relationships between input features separated by time. State of the art models such as…
How Can We Be So Dense? The Benefits of Using Highly Sparse Representations
Subutai Ahmad, Luiz Scheinkman
Most artificial networks today rely on dense representations, whereas biological networks rely on sparse representations. In this paper we show how sparse representations can be mo…
Properties of Sparse Distributed Representations and their Application to Hierarchical Temporal Memory
Subutai Ahmad, Jeff Hawkins
Empirical evidence demonstrates that every region of the neocortex represents information using sparse activity patterns. This paper examines Sparse Distributed Representations (SD…
