🚨New preprint w/ Leyla Isik! Aligning Video Models with Human Social Judgments via Behavior-Guided Fine-Tuning We introduce a ~49k triplet social video dataset, uncover a modality gap (language > video), and close via novel behavior-guided finetuning. 🔗 arxiv.org/abs/2510.01502

I’m very happy to share our paper, Revisiting Rainbow, accepted in the Deep RL workshop @Neurips_Conf. I’ve been working with @pcastr for a few months, and I wanted to share my story, and how this work came to be, in the hope it motivates others in similar situations to mine.

Happy to share "Revisiting Rainbow" w/ @JS_Obando where we argue small/mid-scale envs can promote more insightful & inclusive deep RL research. 📜Paper: arxiv.org/abs/2011.14826 ✍️🏾Blog: bit.ly/2VkPJ4r 🐍Code: bit.ly/3mrCyuD 📽️Video: bit.ly/2I0BAXk 🧵1/X

Excited to share that I’m at #NeurIPS2025 this year! 🧠 I’ll be presenting at the UniReps Workshop on my work on Social Tokens with @su1001v and @thisismyhat, where we explore how to inject socially relevant visual features into language models to improve social reasoning and alignment. Super excited to connect with folks working at the intersection of multimodal models and human cognition. If you’re around, come say hi! And feel free to DM me for a coffee chat ☕️

🚀 The “Dormant Neuron” [1] work showed that deep RL agents lose capacity when neurons stop activating. But what if neurons look dormant yet are still learning? Our #NeurIPS2025 paper revisits this question; using gradients instead of activations to measure real neuronal health. GraMa offers a clearer view of how deep RL agents actually learn, leading to more adaptive and higher-performing agents. 🧵👇Check out the great thread by @JasonLiu106968

#NeurIPS2025 #AgenticAI 🚀 We're thrilled to share our #NeurIPS2025 paper: Measuring Gradients, Not Activations! Enhancing Neuronal Activity in Deep Reinforcement Learning We identify a flaw in measuring "inactive" neurons in various complex networks and propose focusing on how neurons learn, not their outputs. Paper: arxiv.org/abs/2505.24061 Code: github.com/torressliu/gra… Thread on why gradients reveal true neuronal health in RL agents👇:

1/3 🥳Excited to share our new paper ‘Simplicial Embeddings Improve Sample Efficiency in Actor–Critic Agents’! Project your features onto a product of simplices → sparse, stable reps, stronger grads, faster learning. 🧵For more details, check out Pablo’s thread 👇

🔊Simplicial Embeddings (SEMs) Improve Sample Efficiency in Actor-Critic Agents🔊 In our recent preprint we demonstrate that the use of well-structured representations (SEMs) can dramatically improve sample efficiency in RL agents. 1/X

Excited to share new work with @H_Lee_Masson, Ericka Wodka, @SHMostofsky and Leyla Isik! We investigated how simultaneous vision and language signals are combined in the brain using naturalistic+controlled fMRI. Read the paper here: osf.io/b5p4n 1/n

✅Together this work shows how different types of human similarity judgments can be leveraged to improve video models. We also share our large-scale video similarity judgment dataset, and code for hybrid triplet/RSA behavior guided finetuning: (github.com/garciakathy/si…)

In follow-up experiments, we show this model generalizes better to novel social tasks and avoids catastrophic forgetting by preserving baseline on action recognition tasks.
