GoR: A Unified and Extensible Generative Framework for Ordinal Regression

ICLR 2026poster

Ordinal Regression (OR), which predicts the target values with inherent order, underpins a wide spectrum of applications from computer vision to recommendation systems. The intrinsic ordinal structure and non-stationary inter-class boundaries make OR fundamentally more challenging than conventional…

Invariant Feature Learning for Counterfactual Watch-time Prediction in Video Recommendation

AAAI 2026technical

Video recommendation systems heavily rely on user watch time feedback, making accurate watch time prediction a crucial task. However, this task inherently suffers from bias, as recommendation models tend to favor long-duration videos to maximize watch time. This issue, known as duration bias in the

Enhancing Multi-Task Motion Planning Based on Improved DMPs for Lower Limb Prostheses

IROS 2025

Achieving natural locomotion across diverse environments with prosthetic limbs remains a significant challenge for amputees. Intelligent prosthetics leverage motion planning techniques using phase variables to emulate natural gait aligned with human movement intentions. However, traditional phase va

TorchSpatial: A Location Encoding Framework and Benchmark for Spatial Representation Learning

NeurIPS 2024poster

Spatial representation learning (SRL) aims at learning general-purpose neural network representations from various types of spatial data (e.g., points, polylines, polygons, networks, images, etc.) in their native formats. Learning good spatial representations is a fundamental problem for various dow…
