Adversarial Generative Flow Network for Solving Vehicle Routing Problems

ICLR 2025poster

Recent research into solving vehicle routing problems (VRPs) has gained significant traction, particularly through the application of deep (reinforcement) learning for end-to-end solution construction. However, many current construction-based neural solvers predominantly utilize Transformer architec…

MVMoE: Multi-Task Vehicle Routing Solver with Mixture-of-Experts

ICML 2024poster

Learning to solve vehicle routing problems (VRPs) has garnered much attention. However, most neural solvers are only structured and trained independently on a specific problem, making them less generic and practical. In this paper, we aim to develop a unified neural solver that can cope with a range…

Crafting Monocular Cues and Velocity Guidance for Self-Supervised Multi-Frame Depth Learning

AAAI 2023technical

Self-supervised monocular methods can efficiently learn depth information of weakly textured surfaces or reflective objects. However, the depth accuracy is limited due to the inherent ambiguity in monocular geometric modeling. In contrast, multi-frame depth estimation methods improve depth accuracy…

OpenOccupancy: A Large Scale Benchmark for Surrounding Semantic Occupancy Perception

ICCV 2023poster

Semantic occupancy perception is essential for autonomous driving, as automated vehicles require a fine-grained perception of the 3D urban structures. However, existing relevant benchmarks lack diversity in urban scenes, and they only evaluate front-view predictions. Towards a comprehensive benchmar…

MVSTER: Epipolar Transformer for Efficient Multi-View Stereo

ECCV 2022poster

"Learning-based Multi-View Stereo (MVS) methods warp source images into the reference camera frustum to form 3D volumes, which are fused as a cost volume to be regularized by subsequent networks. The fusing step plays a vital role in bridging 2D semantics and 3D spatial associations. However, previo…

Learning to Dispatch for Job Shop Scheduling via Deep Reinforcement Learning

NeurIPS 2020poster

Priority dispatching rule (PDR) is widely used for solving real-world Job-shop scheduling problem (JSSP). However, the design of effective PDRs is a tedious task, requiring a myriad of specialized knowledge and often delivering limited performance. In this paper, we propose to automatically learn PD…
