Spectral Conformal Risk Control: Distribution-Free Tail Guarantees via Bayesian Quadrature

CVPR 2026

Modern vision systems are deployed in settings where occasional catastrophic failures matter more than average accuracy--for example in medical imaging, autonomous driving, and safety monitoring. While conformal prediction gives distribution-free uncertainty guarantees, most existing methods only co

StreamSplat: Towards Online Dynamic 3D Reconstruction from Uncalibrated Video Streams

ICLR 2026poster

Real-time reconstruction of dynamic 3D scenes from uncalibrated video streams demands robust online methods that recover scene dynamics from sparse observations under strict latency and memory constraints. Yet most dynamic reconstruction methods rely on hours of per-scene optimization under full-seq…

Maximum Likelihood Estimation for Bivariate Joint Distribution Recovery from Max-Aggregated Data

ICASSP 2025accepted

In modern communication systems, to conserve transmission energy, the collected data are often max-aggregated. This aggregation involves observing only the features with relatively larger values in each observed sample. Recovering the joint distribution from such systematically missing data is of gr…

MoFlow: One-Step Flow Matching for Human Trajectory Forecasting via Implicit Maximum Likelihood Estimation based Distillation

CVPR 2025poster

In this paper, we address the problem of human trajectory forecasting, which aims to predict the inherently multi-modal future movements of humans based on their past trajectories and other contextual cues. We propose a novel motion prediction conditional flow matching model, termed MoFlow, to predi…

Neural MJD: Neural Non-Stationary Merton Jump Diffusion for Time Series Prediction

NeurIPS 2025poster

While deep learning methods have achieved strong performance in time series prediction, their black-box nature and inability to explicitly model underlying stochastic processes often limit their robustness handling non-stationary data, especially in the presence of abrupt changes. In this work, we i…

RETRO SYNFLOW: Discrete Flow-Matching for Accurate and Diverse Single-Step Retrosynthesis

NeurIPS 2025poster

A fundamental challenge in organic chemistry is identifying and predicting the sequence of reactions that synthesize a desired target molecule. Due to the combinatorial nature of the chemical search space, single-step reactant prediction—i.e., single-step retrosynthesis—remains difficult, even for s…

TrajFlow: Multi-modal Motion Prediction via Flow Matching

IROS 2025

Efficient and accurate motion prediction is crucial for ensuring safety and informed decision-making in autonomous driving, particularly under dynamic real-world conditions that necessitate multi-modal forecasts. We introduce TrajFlow, a novel flow matching-based motion prediction framework that add

Unveiling the Power of Noise Priors: Enhancing Diffusion Models for Mobile Traffic Prediction

IJCAI 2025

Accurate prediction of mobile traffic,i.e., network traffic from cellular base stations, is crucial for optimizing network performance and supporting urban development. However, the non-stationary nature of mobile traffic, driven by human activity and environmental changes, leads to both regular pat

AutoCast++: Enhancing World Event Prediction with Zero-shot Ranking-based Context Retrieval

ICLR 2024poster

Machine-based prediction of real-world events is garnering attention due to its potential for informed decision-making. Whereas traditional forecasting predominantly hinges on structured data like time-series, recent breakthroughs in language models enable predictions using unstructured text. In par…

CrossLoc: Scalable Aerial Localization Assisted by Multimodal Synthetic Data

CVPR 2022poster

We present a visual localization system that learns to estimate camera poses in the real world with the help of synthetic data. Despite significant progress in recent years, most learning-based approaches to visual localization target at a single domain and require a dense database of geo-tagged ima…
