Siyuan Huang

Seattle I am a fourth year Ph.D. student in the Department of Statistics at University of California, Los Angeles. I am currently doing computer vision research at the Center for Vision, Cognition, Learning, and Autonomy (VCLA) and am advised by Professor Song-Chun Zhu. Before coming to UCLA, I graduated from Tsinghua University with a Bachelors in Department of Automation.


My research interests lie in computer vision, machine learning, cognition, and robotics.
I currently focus on the problem of 3D scene understanding which contains task-oriented vision, 3D scene parsing, reconstruction, and synthesis. I would like to develop tools to help machines learn 3D representations, percept 3D world, and interact with 3D environments from images or videos. My long-term goal is to build an intelligent machine that could think and behave like a human. I also did some work in physical and social scene understanding, neural-symbolic AI.

ECCV 2020 A Competence-aware Curriculum for Visual Concepts Learning via Question Answering
Qing Li , Siyuan Huang, Yining Hong, Song-Chun Zhu
ECCV 2020 (Oral)
We design a neural-symbolic concept learner for learning the visual concepts and a multi-dimensional Item Response Theory (mIRT) model for guiding the visual concept learning process with an adaptive curriculum.


ECCV 2020 LEMMA: A Multi-view Dataset for Learning Multi-agent Multi-task Activities
Baoxiong Jia, Yixin Chen, Siyuan Huang, Yixin Zhu, Song-Chun Zhu
ECCV 2020
We introduce the LEMMA dataset to provide a single home to address these missing dimensions with carefully designed settings, wherein the numbers of tasks and agents vary to highlight different learning objectives. We densely annotate the atomic-actions with human-object interactions to provide ground-truth of the compositionality, scheduling, and assignment of daily activities.

Qing Li , Siyuan Huang, Yining Hong, Yixin Chen, Ying Nian Wu, Song-Chun Zhu
ICML 2020
Paper / Supplementary / Code / Project / Bibtex
We close the loop of neural-symbolic learning by introducing the grammar}model as a symbolic prior to bridge neural perception and symbolic reasoning, and proposing a novel back-search algorithm which mimics the top-down human-like learning procedure to propagate the error through the symbolic reasoning module efficiently.

Paper
We demonstrate the power of this perspective to develop cognitive AI systems with humanlike common sense by showing how to observe and apply FPICU with little training data to solve a wide range of challenging tasks, including tool use, planning, utility inference, and social learning.


TPAMI 2019 Learning V1 simple cells with vector representations of local contents and matrix representations of local motions
Ruiqi Gao , Jianwen Xie , Siyuan Huang, Yufan Ren, Song-Chun Zhu, Ying Nian Wu
Arxiv 2020
Paper
we propose a representational model that couples the vector representations of local image contents with the matrix representations of local pixel displacements. When the image changes from one time frame to the next due to pixel displacements, the vector at each pixel is rotated by a matrix that represents the displacement of this pixel.
