Relative representations for cognitive graphs

1 code implementation9 Sep 2023 Alex B. Kiefer, Christopher L. Buckley

Although the latent spaces learned by distinct neural networks are not generally directly comparable, recent work in machine learning has shown that it is possible to use the similarities and differences among latent space vectors to derive "relative representations" with comparable representational power to their "absolute" counterparts, and which are nearly identical across models trained on similar data distributions.

Efficient search of active inference policy spaces using k-means

1 code implementation6 Sep 2022 Alex B. Kiefer, Mahault Albarracin

We develop an approach to policy selection in active inference that allows us to efficiently search large policy spaces by mapping each policy to its embedding in a vector space.
