Learning cognitive maps for vicarious evaluation

This paper introduces a cognitive graph structure called CSCG to model how the hippocampus forms abstract cognitive maps, explaining various cognitive phenomena and place cell behaviors.

Different clones for different contexts: Hippocampal cognitive maps as higher-order graphs of a cloned HMM

This paper introduces a cloned HMM to model hippocampal cognitive maps as higher-order graphs, showing it captures key properties of hippocampal cells in rodents and humans.

Memorize-Generalize: An online algorithm for learning higher-order sequential structure with cloned Hidden Markov Models

This paper introduces a biologically plausible learning algorithm for Cloned HMMs that enables rapid memorization and gradual generalization of higher-order sequential structures.
