PoMtVRS: Preference-Optimized Multi-Task Vehicle Routing Solver with Preference Gating

ICML 2026poster

Multi-task vehicle routing solvers via deep reinforcement learning have attracted broad attention and achieved significant progress in handling multiple constraints. However, existing neural solvers still face critical challenges, including insufficient representation, unstable training, and ineffic…

Deterministic-to-Stochastic Diverse Latent Feature Mapping for Human Motion Synthesis

CVPR 2025poster

Human motion synthesis aims to generate plausible human motion sequences, which has raised widespread attention in computer animation. Recent score-based generative models (SGMs) have demonstrated impressive results on this task. However, their training process involves complex curvature trajectorie…

EFormer: An Effective Edge-based Transformer for Vehicle Routing Problems

IJCAI 2025

Recent neural heuristics for the Vehicle Routing Problem (VRP) primarily rely on node coordinates as input, which may be less effective in practical scenarios where real cost metrics—such as edge-based distances—are more relevant. To address this limitation, we introduce EFormer, an Edge-based Trans

MTRec: Learning to Align with User Preferences via Mental Reward Models

NeurIPS 2025poster

Recommendation models are predominantly trained using implicit user feedback, since explicit feedback is often costly to obtain. However, implicit feedback, such as clicks, does not always reflect users' real preferences. For example, a user might click on a news article because of its attractive he…

Preference-based Deep Reinforcement Learning for Historical Route Estimation

IJCAI 2025

Recent Deep Reinforcement Learning (DRL) techniques have advanced solutions to Vehicle Routing Problems (VRPs). However, many of these methods focus exclusively on optimizing distance-oriented objectives (i.e., minimizing route length), often overlooking the implicit drivers' preferences for routes.

UniteFormer: Unifying Node and Edge Modalities in Transformers for Vehicle Routing Problems

NeurIPS 2025spotlight

Neural solvers for the Vehicle Routing Problem (VRP) have typically relied on either node or edge inputs, limiting their flexibility and generalization in real-world scenarios. We propose UniteFormer, a unified neural solver that supports node-only, edge-only, and hybrid input types through a single…

SAEIR: Sequentially Accumulated Entropy Intrinsic Reward for Cooperative Multi-Agent Reinforcement Learning with Sparse Reward

IJCAI 2024poster

Multi-agent reinforcement learning (MARL) performs well for solving complex cooperative tasks when the scenarios have well-defined dense rewards. However, there are usually sparse reward settings in many real-world multi-agent systems, which makes it difficult for MARL algorithms to successfully lea…

Co-Speech Gesture Synthesis by Reinforcement Learning With Contrastive Pre-Trained Rewards

CVPR 2023poster

There is a growing demand of automatically synthesizing co-speech gestures for virtual characters. However, it remains a challenge due to the complex relationship between input speeches and target gestures. Most existing works focus on predicting the next gesture that fits the data best, however, su…
