TMR: Text-to-Motion Retrieval Using Contrastive 3D Human Motion Synthesis

no code implementations ICCV 2023 Mathis Petrovich, Michael J. Black, Gül Varol

We show that maintaining the motion generation loss, along with the contrastive training, is crucial to obtain good performance.

SINC: Spatial Composition of 3D Human Motions for Simultaneous Action Generation

no code implementations ICCV 2023 Nikos Athanasiou, Mathis Petrovich, Michael J. Black, Gül Varol

Motivated by the observation that the correspondence between actions and body parts is encoded in powerful language models, we extract this knowledge by prompting GPT-3 with text such as "what are the body parts involved in the action <action name>?

TEACH: Temporal Action Composition for 3D Humans

1 code implementation9 Sep 2022 Nikos Athanasiou, Mathis Petrovich, Michael J. Black, Gül Varol

In particular, our goal is to enable the synthesis of a series of actions, which we refer to as temporal action composition.

TEMOS: Generating diverse human motions from textual descriptions

1 code implementation25 Apr 2022 Mathis Petrovich, Michael J. Black, Gül Varol

In contrast to most previous work which focuses on generating a single, deterministic, motion from a textual description, we design a variational approach that can produce multiple diverse human motions.

Action-Conditioned 3D Human Motion Synthesis with Transformer VAE

2 code implementations ICCV 2021 Mathis Petrovich, Michael J. Black, Gül Varol

By sampling from this latent space and querying a certain duration through a series of positional encodings, we synthesize variable-length motion sequences conditioned on a categorical action.

Feature-Robust Optimal Transport for High-Dimensional Data

no code implementations1 Jan 2021 Mathis Petrovich, Chao Liang, Ryoma Sato, Yanbin Liu, Yao-Hung Hubert Tsai, Linchao Zhu, Yi Yang, Ruslan Salakhutdinov, Makoto Yamada

To show the effectiveness of FROT, we propose using the FROT algorithm for the layer selection problem in deep neural networks for semantic correspondence.

FsNet: Feature Selection Network on High-dimensional Biological Data

2 code implementations23 Jan 2020 Dinesh Singh, Héctor Climente-González, Mathis Petrovich, Eiryo Kawakami, Makoto Yamada

Because a large number of parameters in the selection and reconstruction layers can easily result in overfitting under a limited number of samples, we use two tiny networks to predict the large, virtual weight matrices of the selection and reconstruction layers.
