Graph Value Iteration

no code implementations20 Sep 2022 Dieqiao Feng, Carla P. Gomes, Bart Selman

We propose a domain-independent method that augments graph search with graph value iteration to solve hard planning instances that are out of reach for domain-specialized solvers.

Left Heavy Tails and the Effectiveness of the Policy and Value Networks in DNN-based best-first search for Sokoban Planning

no code implementations28 Jun 2022 Dieqiao Feng, Carla Gomes, Bart Selman

To better understand why these approaches work, we studied the interplay of the policy and value networks of DNN-based best-first search on Sokoban and show the surprising effectiveness of the policy network, further enhanced by the value network, as a guiding heuristic for the search.

A Novel Automated Curriculum Strategy to Solve Hard Sokoban Planning Instances

no code implementations NeurIPS 2020 Dieqiao Feng, Carla P. Gomes, Bart Selman

In particular, as the size of the instance pool increases, the ``hardness gap'' decreases, which facilitates a smoother automated curriculum based learning process.

The Remarkable Effectiveness of Combining Policy and Value Networks in A*-based Deep RL for AI Planning

no code implementations29 Sep 2021 Dieqiao Feng, Carla P Gomes, Bart Selman

To better understanding why these approaches work we study the interplay of the policy and value networks in A\textsc{*}-based deep RL and show the surprising effectiveness of the policy network, further enhanced by the value network, as a guiding heuristic for A\textsc{*}.

Solving Hard AI Planning Instances Using Curriculum-Driven Deep Reinforcement Learning

1 code implementation4 Jun 2020 Dieqiao Feng, Carla P. Gomes, Bart Selman

Despite significant progress in general AI planning, certain domains remain out of reach of current AI planning systems.

GeneGAN: Learning Object Transfiguration and Attribute Subspace from Unpaired Data

2 code implementations14 May 2017 Shuchang Zhou, Taihong Xiao, Yi Yang, Dieqiao Feng, Qinyao He, Weiran He

In this work, we propose a model that can learn object transfiguration from two unpaired sets of images: one set containing images that "have" that kind of object, and the other set being the opposite, with the mild constraint that the objects be located approximately at the same place.

Training Bit Fully Convolutional Network for Fast Semantic Segmentation

no code implementations1 Dec 2016 He Wen, Shuchang Zhou, Zhe Liang, Yuxiang Zhang, Dieqiao Feng, Xinyu Zhou, Cong Yao

Fully convolutional neural networks give accurate, per-pixel prediction for input images and have applications like semantic segmentation.
