- Reposted by Jungsun Yoo, Ph.D.gooood morning #SfN2025! i’m presenting this poster at board CC11 *today* from 8am-noon stop by to chat learning, memory, (perceptual) decision making, and normative modeling that bridges cross-species and cross-task findings 🧠🐒 w/ @meganakpeters.bsky.social and @aaronbornstein.bsky.social
- Good morning from San Diego. Come see my poster (UU7) on splitting and merging latent states in non-Markovian environments, at #Sfn2025 right now !
- Monday Morning UU7 - Contingency-dependent state augmentation as a normative learning rule for non-Markovian tasks by @jungsuy.bsky.social, Aidan Goeschel, and @dalezhou.bsky.social www.abstractsonline.com/pp8/#!/21171...
- All the best on your new journey in Tucson, @arikahn.bsky.social — the Daw Lab will miss you!
- Reposted by Jungsun Yoo, Ph.D.Are world models necessary to achieve human-level agents, or is there a model-free short-cut? Our new #ICML2025 paper tackles this question from first principles, and finds a surprising answer, agents _are_ world models… 🧵 arxiv.org/abs/2506.01622
- Reposted by Jungsun Yoo, Ph.D.More evidence that distal tuft dendrites provide some form of target/credit signal in hippocampus: www.cell.com/neuron/abstr... #neuroscience 🧪
- Finally hooded, by my wonderful advisor @aaronbornstein.bsky.social !
- Reposted by Jungsun Yoo, Ph.D.super excited that the first paper from my PhD is now out! we develop a "philosophical toolkit" for computational cognitive modeling & use it to conceptually re-analyze a long-standing debate about evidence accumulation models of decision making 🧠📈 onlinelibrary.wiley.com/doi/full/10....
- Thank you! I really tried hard to not tear up when I was mentioning you & the lab during the acknowledgements 😢 I am so fortunate to have been part of such a beautiful community!
- Congratulations to Dr. Jungsun Yoo (@jungsuy.bsky.social) on her successful PhD defense! We're sad that her time with us is past, but excited to see how her future research trajectory unfolds working with @yaelniv.bsky.social and @nathanieldaw.bsky.social
- And thanks for the celebration dinner 🥺 It was the best sushi I had!
- Reposted by Jungsun Yoo, Ph.D.Why do we remember some events but forget others? In our recent work published at @naturecomms.bsky.social, @audreyduarte.bsky.social and I used machine learning to simultaneously quantify multiple cognitive components of episodic memory. www.nature.com/articles/s41... 1/11
- Reposted by Jungsun Yoo, Ph.D.Accepting “the bitter lesson” and embracing the brain’s complexity by Dyer and Richards. Great article! www.thetransmitter.org/neuroai/acce...
- Reposted by Jungsun Yoo, Ph.D.New preprint from Yining Ding (@liliand.bsky.social)! "Temporal order memory in naturalistic events is scaffolded by semantic knowledge and hierarchical event structure" osf.io/preprints/ps...
- Reposted by Jungsun Yoo, Ph.D.Excellent resource here, including a slide deck, for teaching students about science funding! Any similar additional resources out there? I would love to add some graphics quantifying the consequences of the current attacks on science.
- Reposted by Jungsun Yoo, Ph.D.So happy that our paper on event segmentation in large language models is now out in Behavior Research Methods! tinyurl.com/2j76882b With @mtoneva.bsky.social, @ptoncompmemlab.bsky.social, and Manoj Kumar, we show that LLMs can segment narrative text into meaningful events similarly to humans.
- Reposted by Jungsun Yoo, Ph.D.What papers do you like that demonstrate the use of 'orthogonal subspaces' for encoding information in neural populations? #neuroskyence #compneuro #neuroAI
- Reposted by Jungsun Yoo, Ph.D.I love the uncompromising defense of absolute stupidity. I sometimes explain it to students using Keats' phrase 'negative capability'. Can you be comfortable with not knowing?
- Three must read papers for PhD students. #scisky #PhD #science #research #academicsky 1. The importance of stupidity in scientific research Open Access journals.biologists.com/jcs/article/...
- Reposted by Jungsun Yoo, Ph.D.Could we get away with (1) region specific RPEs and (2) no end-to-end training? Is that how the brain works? My guess is yes to (1), no to (2). This paper from our "cousins" at @vectorinst.bsky.social is exploring thes issues and has some promising results! arxiv.org/abs/2411.03604 #NeuroAI 🧪
- Reposted by Jungsun Yoo, Ph.D.Our work on inductive biases in reinforcement learning is out: tinyurl.com/yfc74e3u By the fantastic @noahedrich.bsky.social Ppl learn faster from slowly changing features; we argue this reflects an inductive bias. Teamwork w @ericschulz.bsky.social & S HallMcMaster #neuroskyence #compneuro
- Reposted by Jungsun Yoo, Ph.D.Important paper! www.biorxiv.org/content/bior... Im not sure the Discussion fully delineates its radical implications. No more... * Place cells * Grid cells, splitter cells, border cells * Mirror neurons * Reward neurons * Conflict cells (continued)
- Reposted by Jungsun Yoo, Ph.D.ICYMI on X/Twitter...if you are into space, cognitive maps, place cells, planning, replay, etc., I predict that this blog+paper will change the way you think about those ideas. Goes against the conventional Kantian thought that space is apriori ... blog.dileeplearning.com/p/space-is-a...
- Reposted by Jungsun Yoo, Ph.D.Do you know www.brainfacts.org? Terrific, accessible (free!) articles there about what’s new in brain research. Like this timely piece! The neuroscience behind conspiracy theories. www.brainfacts.org/thinking-sen... I’m delighted to soon step into an editorial role at this terrific effort!
- Reposted by Jungsun Yoo, Ph.D.Do you teach neuroscience? Here’s a list I’ve compiled of mostly free online neuroscience textbooks, simulations and datasets you can use for your course! If I’m missing something, let me know so I can add it! docs.google.com/document/d/1...
- Reposted by Jungsun Yoo, Ph.D.Super-psyched to share this preprint from my student Yicong (Alan) Zheng: "Recurrent Inhibitory Dynamics in the Entorhinal Cortex Support Pattern Separation" www.biorxiv.org/content/10.1... It's a new biologicaly-based computational model of the entorhinal-hippocampal system. Thread (1/?)
- Reposted by Jungsun Yoo, Ph.D.OK folks, I've started an episodic memory starter pack. By no means a full list so reply below if you're an episodic memory nerd! go.bsky.app/2mtNK43at://did:plc:p2w4gkdtsur2y23bjlxxali2/app.bsky.graph.starterpack/3larsjycys225
