DriftLite: Lightweight Drift Control for Inference-Time Scaling of Diffusion Models

ICLR 2026poster

We study inference-time scaling for diffusion models, where the goal is to adapt a pre-trained model to new target distributions without retraining. Existing guidance-based methods are simple but introduce bias, while particle-based corrections suffer from weight degeneracy and high computational co…

Generative Modeling from Black-Box Corruptions via Self-Consistent Stochastic Interpolants

ICLR 2026poster

Transport-based methods have emerged as a leading paradigm for building generative models from large, clean datasets. However, in many scientific and engineering domains, clean data are often unavailable: instead, we only observe measurements corrupted through a noisy, ill-conditioned channel. A gen…

Test-time Generalization for Physics through Neural Operator Splitting

ICML 2026poster

Neural operators have shown promise in learning solution maps of partial differential equations (PDEs), but they often struggle to generalize when test inputs lie outside the training distribution, such as novel initial conditions, unseen PDE coefficients or unseen physics. Prior works address this …

DISCO: learning to DISCover an evolution Operator for multi-physics-agnostic prediction

ICML 2025poster

We address the problem of predicting the next states of a dynamical system governed by *unknown* temporal partial differential equations (PDEs) using only a short trajectory. While standard transformers provide a natural black-box solution to this task, the presence of a well-structured evolution op…

Stochastic Optimal Control Matching

NeurIPS 2024poster

Stochastic optimal control, which has the goal of driving the behavior of noisy systems, is broadly applicable in science, engineering and artificial intelligence. Our work introduces Stochastic Optimal Control Matching (SOCM), a novel Iterative Diffusion Optimization (IDO) technique for stochastic…

Global Convergence of Policy Gradient for Linear-Quadratic Mean-Field Control/Game in Continuous Time

ICML 2021spotlight

Recent years have witnessed the success of multi-agent reinforcement learning, which has motivated new research directions for mean-field control (MFC) and mean-field game (MFG), as the multi-agent system can be well approximated by a mean-field problem when the number of agents grows to be very lar…

On the Curse of Memory in Recurrent Neural Networks: Approximation and Optimization Analysis

ICLR 2021poster

We study the approximation properties and optimization dynamics of recurrent neural networks (RNNs) when applied to learn input-output relationships in temporal data. We consider the simple but representative setting of using continuous-time linear RNNs to learn from data generated by linear relatio…

End-to-end Symmetry Preserving Inter-atomic Potential Energy Model for Finite and Extended Systems

NeurIPS 2018poster

Machine learning models are changing the paradigm of molecular modeling, which is a fundamental tool for material science, chemistry, and computational biology. Of particular interest is the inter-atomic potential energy surface (PES). Here we develop Deep Potential - Smooth Edition (DeepPot-SE), an…
