Uniform Diffusion Models Revisited: Leave-One-Out Denoiser and Absorbing State Reformulation

Samson Gourevitch, Yazid Janati, Dario Shariatian +4

Discrete diffusion models are often trained through clean-data prediction, but the prediction can be used in different ways to define the reverse dynamics. In Masked Diffusion Mode…

Efficient Agentic Reasoning Through Self-Regulated Simulative Planning

Mingkai Deng, Jinyu Hou, Lara Sá Neves +4

How should an agent decide when and how to plan? A dominant approach builds agents as reactive policies with adaptive computation (e.g., chain-of-thought), trained end-to-end expec…

CHI-Bench: Can AI Agents Automate End-to-End, Long-Horizon, Policy-Rich Healthcare Workflows?

Haolin Chen, Deon Metelski, Leon Qi +30

End-to-end automation of realistic healthcare operations stresses three capabilities underrepresented in current benchmarks: policy density, decisions must be grounded in a large l…

In-context Learning of Evolving Data Streams with Tabular Foundational Models

Afonso Lourenço, João Gama, Eric P. Xing +1

State-of-the-art data stream mining has long drawn from ensembles of the Very Fast Decision Tree, a seminal algorithm honored with the 2015 KDD Test-of-Time Award. However, the eme…

Bridging Streaming Continual Learning via In-Context Large Tabular Models

Afonso Lourenço, João Gama, Eric P. Xing +1

In streaming scenarios, models must learn continuously, adapting to concept drifts without erasing previously acquired knowledge. However, existing research communities address the…
