Happy to share this: Deep generative model insight into the organization of top-down connections. [Paper](www.nature.com/articles/s41...) @natcomms.nature.com shows native TD in hierarchical deep generative models (as opposed to dominantly FF deep discriminative models) match V2 - V1 influences.
Top-down perceptual inference shaping the activity of early visual cortex - Nature Communications
How top-down connections are shaped by hierarchical inference is explained through developing a deep-generative model. V2-like texture representation is shown to emerge through natural experiences, wh...

Fresh out of the oven. 3-armed bandit task: A quintessential RL paradigm. Is it every bit an RL task for monkeys? We tracked the arithmetic of population activity in MCC+vlPFC+dlPFC and identified foraging-like computations instead of Q-learning. A fun collaboration with the Procyk Lab (INSERM).

I am happy to share the story that just came out at @natrevpsychol.nature.com on a normative treatment of memory dynamics

good morning, that's my dawn at bluesky. let's assume I am right in time for the party.
