PARCO: Learning Parallel Autoregressive Policies for Efficient Multi-Agent Combinatorial Optimization

1 code implementation5 Sep 2024 Federico Berto, Chuanbo Hua, Laurin Luttmann, Jiwoo Son, Junyoung Park, Kyuree Ahn, Changhyun Kwon, Lin Xie, Jinkyoo Park

Multi-agent combinatorial optimization problems such as routing and scheduling have great practical relevance but present challenges due to their NP-hard combinatorial nature, hard constraints on the number of possible agents, and hard-to-optimize objective functions.

Identification and Estimation of the Bi-Directional MR with Some Invalid Instruments

no code implementations10 Jul 2024 Feng Xie, Zhen Yao, Lin Xie, Yan Zeng, Zhi Geng

We consider the challenging problem of estimating causal effects from purely observational data in the bi-directional Mendelian randomization (MR), where some invalid instruments, as well as unmeasured confounding, usually exist.

Formulating and solving integrated order batching and routing in multi-depot AGV-assisted mixed-shelves warehouses

1 code implementation27 Jan 2021 Lin Xie, Hanyi Li, Laurin Luttmann

Due to the complexity of the integrated problem, we develop a novel variable neighborhood search algorithm to solve the integrated problem more efficiently.

An Intelligent CNN-VAE Text Representation Technology Based on Text Semantics for Comprehensive Big Data

no code implementations28 Aug 2020 Genggeng Liu, Canyang Guo, Lin Xie, Wenxi Liu, Naixue Xiong, Guolong Chen

CNN is used to extract the features of text vector to get the semantics among words and VAE is introduced to make the text feature space more consistent with Gaussian distribution.
