Bio

I am a second-year Ph.D. student at Computer Science & Artificial Intelligence Laboratory (CSAIL) at MIT, supervised by Prof. Wojciech Matusik. Before coming to MIT, I received my M.Phil. from the Chinese University of Hong Kong, supervised by Prof. Dahua Lin. I got my Bachelor's degree from Tsinghua University.

I am generally interested in computational design problems at the intersection of geometry processing and machine learning. My current focus is on combining the expressivity of procedural modeling and machine learning for the generation and inverse design of graphs, with a wide spectrum of applications to molecules, smart materials, and, more notably, 3D shapes. By means of developing high-performance optimization algorithms and frameworks, I am excited to work with everything that is visually impressive and practically efficient.

Data-Efficient Graph Grammar Learning for Molecular Generation
 Minghao Guo, Veronika Thost, Beichen Li, Payel Das, Jie Chen, Wojciech Matusik
International Conference on Learning Representations (ICLR) 2022
Oral Presentation [acceptance rate: 1.6%]
[PDF] [Code]

Abstract

A data-efficient generative model that can be learned from datasets with orders of magnitude smaller sizes than common benchmarks. At the heart of this method is a learnable graph grammar that generates molecules from a sequence of production rules. Our learned graph grammar yields state-of-the-art results on generating high-quality molecules for three monomer datasets that contain only ∼20 samples each.

PolyGrammar: Grammar for Digital Polymer Representation and Generation
 Minghao Guo, Liane Makatura, Wan Shou, Timothy Erps, Michael Foshey, Wojciech Matusik
Advanced Science
[PDF]

Abstract

A formal grammar specifically designed for the polymers, providing a concise, explicit, and robust representation for any polymer within a given class. This project serves as a foundational blueprint for constructing general chemical design models, with closely integrated representation and generative capabilities.

Pareto Gamuts: Exploring Optimal Designs Across Varying Contexts
 Liane Makatura, Minghao Guo, Adriana Schulz, Justin Solomon, Wojciech Matusik
ACM Transactions on Graphics 2021 (SIGGRAPH 2021)
[PDF] [Project Page] [Video]

Abstract

A framework for variable-context multi-objective optimization capturing Pareto fronts over a range of contexts (Pareto gamut). A global-local optimization algorithm is developed to discover the Pareto gamut. Its practical utility is demonstrated for several engineering design problems.

When NAS Meets Robustness: In Search of Robust Architectures against Adversarial Attacks
 Minghao Guo*, Yuzhe Yang*, Rui Xu, Ziwei Liu, Dahua Lin
Conference on Computer Vision and Pattern Recognition (CVPR) 2020
[PDF] [Project Page] [Code] [Video]

Abstract

Take the first step to understand adversarial robustness of neural networks from an architectural perspective. Based on our “robust architecture Odyssey”, we design a family of robust architectures RobNets that exhibit superior robustness performance to other widely used architectures.

Online Hyper-parameter Learning for Auto-Augmentation Strategy
 Chen Lin*, Minghao Guo*, Chuming Li, Xin Yuan, Wei Wu, Junjie Yan, Dahua Lin, Wanli Ouyang
International Conference on Computer Vision (ICCV) 2019
[PDF]

Abstract

An economical solution that learns the data augmentation policy along with network training. The augmentation policy is formulated as a parameterized probability distribution, thus allowing its parameters to be optimized jointly with network parameters. Compared with SOTA methods, this framework achieves 60× faster on CIFAR-10 and 24× faster on ImageNet, while maintaining competitive accuracies.

IRLAS: Inverse Reinforcement Learning for Architecture Search
 Minghao Guo, Zhao Zhong, Wei Wu, Dahua Lin, Junjie Yan
Conference on Computer Vision and Pattern Recognition (CVPR) 2019
[PDF] [Code]

Abstract

An inverse reinforcement learning framework for the training of an agent to learn to search network structures that are topologically inspired by human-designed network. A mirror stimuli function motivated by biological cognition theory is proposed to extract the abstract topological knowledge and facilitates the discovery of architectures that stride a satisfactory balance between accuracy and efficiency.

Dual-Agent Deep Reinforcement Learning for Deformable Face Tracking
 Minghao Guo, Jiwen Lu, Jie Zhou
European Conference on Computer Vision (ECCV) 2018
Oral Presentation [acceptance rate: 2.4%]
[PDF] [Video]

Abstract

A deformable face tracking system that can automatically balance the efficiency and effectiveness according to the image quality and tracking complexity of each frame. Dual-agent deep reinforcement learning is used to make adaptive decisions to position updates of bounding boxes and landmarks. The interaction of these two subtasks is explicitly exploited following a Bayesian model.
