There is nothing better than working with smart and genuinely kind people! We found that intellectual humility in science communication boosts trust in science. Preprint here and now in press at Nature Human Behaviour! osf.io/preprints/psya… 🧵
LLMs Can In-context Learn Multiple Tasks in Superposition We explore a bizarre LLM superpower that allows them to solve multiple ICL tasks in parallel. This is related to the view of them as simulators in superposition [cref:@repligate] arxiv.org/pdf/2410.05603 1/n
Our latest work got published nature.com/articles/s4158…. We found that behavioral time scale plasticity (BTSP), which is relevant for place cell induction, is synapse specific in proximal apical dendrite. Although it follows properties similar to Hebbian plasticity, (1/4)
