Afternoon session with Qiong Zhang, Lila Davachi, Mike Katana, and @barense.bsky.social. Qiong starts us off with a talk about how (formal) theory of memory could be extended to account for more realistic setting.

Next up is @pstjacques.bsky.social discussing how the immersiveness (not a word?) of the real world affects memory.

First talk by Sudeep Bhatia on modeling unconstrained memory retrieval. When you decide what to eat during lunch break, which foods come to mind and why?

Finished preparing the lecture for tomorrow and I am so excited about teaching it. There are two reasons: 1. It's about Bayesian estimation, and 2. It's about my cat.
