Symbolic Music Generation with Non-Differentiable Rule Guided Diffusion

1 code implementation22 Feb 2024 Yujia Huang, Adishree Ghatare, Yuanzhe Liu, Ziniu Hu, Qinsheng Zhang, Chandramouli S Sastry, Siddharth Gururani, Sageev Oore, Yisong Yue

We propose Stochastic Control Guidance (SCG), a novel guidance method that only requires forward evaluation of rule functions that can work with pre-trained diffusion models in a plug-and-play way, thus achieving training-free guidance for non-differentiable rules for the first time.

FI-ODE: Certifiably Robust Forward Invariance in Neural ODEs

1 code implementation30 Oct 2022 Yujia Huang, Ivan Dario Jimenez Rodriguez, huan zhang, Yuanyuan Shi, Yisong Yue

Forward invariance is a long-studied property in control theory that is used to certify that a dynamical system stays within some pre-specified set of states for all time, and also admits robustness guarantees (e. g., the certificate holds under perturbations).

Diffusion Models for Adversarial Purification

2 code implementations16 May 2022 Weili Nie, Brandon Guo, Yujia Huang, Chaowei Xiao, Arash Vahdat, Anima Anandkumar

Adversarial purification refers to a class of defense methods that remove adversarial perturbations using a generative model.

Training Certifiably Robust Neural Networks with Efficient Local Lipschitz Bounds

1 code implementation NeurIPS 2021 Yujia Huang, huan zhang, Yuanyuan Shi, J Zico Kolter, Anima Anandkumar

Certified robustness is a desirable property for deep neural networks in safety-critical applications, and popular training algorithms can certify robustness of a neural network by computing a global bound on its Lipschitz constant.

Neural Networks with Recurrent Generative Feedback

1 code implementation NeurIPS 2020 Yujia Huang, James Gornet, Sihui Dai, Zhiding Yu, Tan Nguyen, Doris Y. Tsao, Anima Anandkumar

This mechanism can be interpreted as a form of self-consistency between the maximum a posteriori (MAP) estimation of an internal generative model and the external environment.

Semantic-driven Generation of Hyperlapse from $360^\circ$ Video

no code implementations31 Mar 2017 Wei-Sheng Lai, Yujia Huang, Neel Joshi, Chris Buehler, Ming-Hsuan Yang, Sing Bing Kang

We present a system for converting a fully panoramic ($360^\circ$) video into a normal field-of-view (NFOV) hyperlapse for an optimal viewing experience.

Pose Invariant Embedding for Deep Person Re-identification

no code implementations26 Jan 2017 Liang Zheng, Yujia Huang, Huchuan Lu, Yi Yang

Second, to reduce the impact of pose estimation errors and information loss during PoseBox construction, we design a PoseBox fusion (PBF) CNN architecture that takes the original image, the PoseBox, and the pose estimation confidence as input.
