Language models represent space and time

W Gurnee, M Tegmark - arXiv preprint arXiv:2310.02207, 2023 - arxiv.org
The capabilities of large language models (LLMs) have sparked debate over whether such
systems just learn an enormous collection of superficial statistics or a coherent model of the …

The influence of emotion on temporal context models

LJ Lohnas, MW Howard - Cognition and Emotion, 2024 - Taylor & Francis
Temporal context models (TCMs) have been influential in understanding episodic memory
and its neural underpinnings. Recently, TCMs have been extended to explain emotional …

Integration and competition between space and time in the hippocampus

S Chen, N Cheng, X Chen, C Wang - Neuron, 2024 - cell.com
Episodic memory is organized in both spatial and temporal contexts. The hippocampus is
crucial for episodic memory and has been demonstrated to encode spatial and temporal …

Interoceptive and bodily processing in prospective and retrospective timing

A Teghil - 2024 - Springer
This chapter reviews some directions along which Craig's proposal of subjective time as
emergent from interoceptive and bodily dynamics allows to frame recent findings on …

[HTML][HTML] Foundations of a temporal RL

MW Howard, ZG Esfahani, B Le, PB Sederberg - ArXiv, 2023 - ncbi.nlm.nih.gov
Recent advances in neuroscience and psychology show that the brain has access to
timelines of both the past and the future. Spiking across populations of neurons in many …

Temporal encoding in deep reinforcement learning agents

D Lin, AZ Huang, BA Richards - Scientific Reports, 2023 - nature.com
Neuroscientists have observed both cells in the brain that fire at specific points in time,
known as “time cells”, and cells whose activity steadily increases or decreases over time …

MTL neurons phase-lock to human hippocampal theta

DR Schonhaut, AM Rao, AG Ramayya, EA Solomon… - Elife, 2024 - elifesciences.org
Memory formation depends on neural activity across a network of regions, including the
hippocampus and broader medial temporal lobe (MTL). Interactions between these regions …

Formal models of memory based on temporally-varying representations

MW Howard - The new handbook of mathematical psychology, 2022 - cambridge.org
Human babies, while adorable, are remarkably incompetent. They know essentially no facts
about the world, are unable to perform any but the simplest motor actions, and perform very …

Constructing condensed memories in functorial time

S Dobson, C Fields - Journal of Experimental & Theoretical Artificial …, 2023 - Taylor & Francis
If episodic memory is constructive, experienced time is also a construct. We develop an
event-based formalism that replaces the traditional objective, agent-independent notion of …

Same principle, but different computations in representing time and space

S Sima, M Sanayei - Frontiers in Neuroscience, 2024 - frontiersin.org
Time and space are two intertwined contexts that frame our cognition of the world and have
shared mechanisms. A well-known theory on this case is “A Theory of Magnitude (ATOM)” …
