Rethinking the Flow-based Gradual Domain Adaption: A Semi-Dual Optimal Transport Perspective

ICML 2026poster

Gradual Domain Adaption (GDA) aims to mitigate domain shift by progressively adapting models from the source domain to the target domain via intermediate domains. However, real intermediate domains are often unavailable or ineffective, necessitating the synthesis of intermediate samples. Flow-based …

Towards Stable Self-Supervised Object Representations in Unconstrained Egocentric Video

CVPR 2026

Humans develop visual intelligence through perceiving and interacting with their environment--a self-supervised learning process grounded in egocentric experience. Inspired by this, we ask how can artificial systems learn stable object representations from continuous, uncurated first-person videos w

Inverse Methods for Missing Data Imputation

NeurIPS 2025poster

Iterative imputation is a prevalent method for completing missing data, which involves iteratively imputing each feature by treating it as a target variable and predicting its missing values using the remaining features. However, existing iterative imputation methods exhibit two critical defects: (…

Optimal Transport for Time Series Imputation

ICLR 2025poster

Missing data imputation through distribution alignment has demonstrated advantages for non-temporal datasets but exhibits suboptimal performance in time-series applications. The primary obstacle is crafting a discrepancy measure that simultaneously (1) captures temporal patterns—accounting for perio…
