Gradient Descent on Variational Free Energy
supports
Process by which neuronal dynamics minimize free energy; produces empirically observable neural phenomena.

cosine ≥ 0.65 · no typed edge

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

Place Cellsconcept0.891
Hippocampal neurons with spatially-specific firing; TEM-t memory neurons resemble these and remap randomly between environments.
Place Cell Remappingconcept0.810
Phenomenon where place cells change their spatial tuning across environments; TEM-t memory neurons exhibit this property.
cellsconcept0.771
Biological units that are considered unconventional media for problem-solving in diverse intelligence.
Band Cellsconcept0.741
Spatially periodic band-like firing neurons described by Krupic et al.; also recapitulated by TEM-t position encodings.
actionconcept0.735
Changing configuration to sample environment differently; minimizes free energy.
Grid Cellsconcept0.729
Spatially periodic firing neurons in medial entorhinal cortex; TEM-t learns representations resembling these.
Action Potentialsconcept0.720
Electrical signals that plants display, propagating along vascular networks, analogous to animal neural signals.
