Simulation-guided Beam Search for Neural Combinatorial Optimization

NeurIPS 2022accept

Neural approaches for combinatorial optimization (CO) equip a learning mechanism to discover powerful heuristics for solving complex real-world problems. While neural approaches capable of high-quality solutions in a single shot are emerging, state-of-the-art approaches are often unable to take full…

Matrix encoding networks for neural combinatorial optimization

NeurIPS 2021poster

Machine Learning (ML) can help solve combinatorial optimization (CO) problems better. A popular approach is to use a neural net to compute on the parameters of a given CO problem and extract useful information that guides the search for good solutions. Many CO problems of practical importance can be…

VaB-AL: Incorporating Class Imbalance and Difficulty With Variational Bayes for Active Learning

CVPR 2021poster

Active Learning for discriminative models has largely been studied with the focus on individual samples, with less emphasis on how classes are distributed or which classes are hard to deal with. In this work, we show that this is harmful. We propose a method based on the Bayes' rule, that can natura…

POMO: Policy Optimization with Multiple Optima for Reinforcement Learning

NeurIPS 2020poster

In neural combinatorial optimization (CO), reinforcement learning (RL) can turn a deep neural net into a fast, powerful heuristic solver of NP-hard problems. This approach has a great potential in practical applications because it allows near-optimal solutions to be found without expert guides armed…
