TEM Learned Representations Reflect Transition Statistics
When the agent’s transition statistics mimic different behaviors, TEM learns new representations (left to right: different cells; top to bottom: environments 1, 2, real data).
(A) When biased to move toward objects (white dots) TEM learns structural cells with a vector relationship to the objects—object vector cells (Høydal et al., 2019). These cells generalize to all objects.
(B) TEM hippocampal cells reflect this behavioral transition change with similar cells, though they do not generalize to all objects—landmark cells (Deshmukh and Knierim, 2013).
(C) When biased toward boundaries, TEM learns border cell-like representations (Solstad et al., 2008).
