Surface-Aligned Neural Radiance Fields for Controllable 3D Human Synthesis

no code implementations CVPR 2022 Tianhan Xu, Yasuhiro Fujita, Eiichi Matsumoto

Our method defines the neural scene representation on the mesh surface points and signed distances from the surface of a human body mesh.

Addressing Class Imbalance in Scene Graph Parsing by Learning to Contrast and Score

1 code implementation28 Sep 2020 He Huang, Shunta Saito, Yuta Kikuchi, Eiichi Matsumoto, Wei Tang, Philip S. Yu

Motivated by the fact that detecting these rare relations can be critical in real-world applications, this paper introduces a novel integrated framework of classification and ranking to resolve the class imbalance problem in scene graph parsing.

Map-based Multi-Policy Reinforcement Learning: Enhancing Adaptability of Robots by Deep Reinforcement Learning

no code implementations17 Oct 2017 Ayaka Kume, Eiichi Matsumoto, Kuniyuki Takahashi, Wilson Ko, Jethro Tan

To solve this problem, we propose Map-based Multi-Policy Reinforcement Learning (MMPRL), which aims to search and store multiple policies that encode different behavioral features while maximizing the expected reward in advance of the environment change.

Learning Discrete Representations via Information Maximizing Self-Augmented Training

2 code implementations ICML 2017 Weihua Hu, Takeru Miyato, Seiya Tokui, Eiichi Matsumoto, Masashi Sugiyama

Learning discrete representations of data is a central machine learning task because of the compactness of the representations and ease of interpretation.

Temporal Generative Adversarial Nets with Singular Value Clipping

4 code implementations ICCV 2017 Masaki Saito, Eiichi Matsumoto, Shunta Saito

In this paper, we propose a generative model, Temporal Generative Adversarial Nets (TGAN), which can learn a semantic representation of unlabeled videos, and is capable of generating videos.
