Our postdoctoral researcher Mengcun Gao studies how we build a picture of the world out of the patterns in our experience 🧠 How do learners pick out what matters, organize what they find, and generalize beyond what they've directly seen? She'll be presenting at #psynom26 in November!

Our reward function compression work is now out in Nature Communications! 🎉 In it, we present and empirically test a computational framework that formalizes the trade-offs between goal flexibility and learning efficiency. @annecollins.bsky.social @natureportfolio.nature.com doi.org/10.1038/s414...
Conceptual model of goal-directed reinforcement learning with reward
function compression. In our proposed conceptual model, we break down goald-dependent learning into several parts. Combined with other learning components, an RL learning algorithm informs value estimates W on a given trial t, which are entered into a policy. The agent selects an action a through a joint policy, to which the environment responds by outputting outcome information o and a new state s. A working memory (WM) component organizes and maintains task-relevant information (here, broadly intended and dubbed the task information), used to support the reinforcement learning (RL) process. a Initially, value attribution to o is operated by WM,which maintains the current goal (g) and supports its matching to the experienced outcome to generate a reward r used by the RL agent. WM also holds a trace of recently experienced goals. b If goals share enough similar features,
a compressed reward function can be created, which replaces active goal maintenance and can, over time, be transferred to long-term memory storage. Eventually, the compressed reward function can be directly employed to assign value to experienced outcomes, sparing resources for other WM tasks.

I will say for both this and the de-obfuscated version the search is too consistent across trials so maybe entropy is a tell. But at that point you've paid the bot and then have to make a judgment call.

From maps to new thoughts: can place-cell indexing generate novel cortical states?
Constructing novel states from experience underpins imagination and abstraction. The hippocampal formation is thought to contribute by capturing the relational structure of experiences, but it remains unclear how its abstract relational codes are eventually translated into cortical content representations. I highlight that hippocampal–cortical indexing may scaffold the generation of new states.
