EEG/fNIRS pipelines can feel like a black box when you’re learning. Chenghao Zhou and I built NeuroCode: it runs your script locally, step by step, and AI explains each step using your actual data. Edit code in plain English; map EEGLAB/Homer3 → MNE. ruixip.github.io/NeuroCode/

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 think there’s still a thrill for connectionist labs, given how long the road was / how cold the winters were. A key part of the program is finding organizing principles, not just existence proofs. There’s plenty of good work still being done this way, but I think it’s harder to do well with LLMs
