Sat2Flow: A Structure-Aware Diffusion Framework for Human Flow Generation from Satellite Imagery

AAAI 2026technical

Origin-Destination (OD) flow matrices are critical for urban mobility analysis, supporting traffic forecasting, infrastructure planning, and policy design. Existing methods face two key limitations: (1) reliance on costly auxiliary features (e.g., Points of Interest, socioeconomic statistics) with l

MMPN: Multi-supervised Mask Protection Network for Pansharpening

IJCAI 2023poster

Pansharpening is to fuse a panchromatic (PAN) image with a multispectral (MS) image to obtain a high-spatial-resolution multispectral (HRMS) image. The deep learning-based pansharpening methods usually apply the convolution operation to extract features and only consider the similarity of gradient i…

Sample Average Approximation for Stochastic Optimization with Dependent Data: Performance Guarantees and Tractability

AAAI 2022technical

Sample average approximation (SAA), a popular method for tractably solving stochastic optimization problems, enjoys strong asymptotic performance guarantees in settings with independent training samples. However, these guarantees are not known to hold generally with dependent samples, such as in onl…
