Rethinking the Diffusion Model from a Langevin Perspective
Candi Zheng, Yuan Lan
Diffusion models are often introduced from multiple perspectives, such as VAEs, score matching, or flow matching, accompanied by dense and technically demanding mathematics that ca…
LanPaint: Training-Free Diffusion Inpainting with Asymptotically Exact and Fast Conditional Sampling
Candi Zheng, Yuan Lan, Yang Wang
Diffusion models excel at joint pixel sampling for image generation but lack efficient training-free methods for partial conditional sampling (e.g., inpainting with known pixels).…
Learning the Optimal Hydrodynamic Closure
Florian Kogelbauer, Candi Zheng, Ilya Karlin
We present the optimal hydrodynamic model for rarefied gas flows relative to a given kinetic model by combining the recent theory of slow spectral closure with machine learning tec…
Early Risk Assessment Model for ICA Timing Strategy in Unstable Angina Patients Using Multi-Modal Machine Learning
Candi Zheng, Kun Liu, Yang Wang +2
Background: Invasive coronary arteriography (ICA) is recognized as the gold standard for diagnosing cardiovascular diseases, including unstable angina (UA). The challenge lies in d…
Characteristic Guidance: Non-linear Correction for Diffusion Model at Large Guidance Scale
Candi Zheng, Yuan Lan
Popular guidance for denoising diffusion probabilistic model (DDPM) linearly combines distinct conditional models together to provide enhanced control over samples. However, this a…
Phase Transition in Extended Thermodynamics Triggers Sub-shocks
Candi Zheng, Yang Wang, Shiyi Chen
Extended thermodynamics commonly uses polynomial moments to model non-equilibrium transportation, but faces a crisis due to sub-shocks, which are anomalous discontinuities in gas p…
Stabilizing the Maximal Entropy Moment Method for Rarefied Gas Dynamics at Single-Precision
Candi Zheng, Wang Yang, Shiyi Chen
The maximal entropy moment method (MEM) is systematic solution of the challenging problem: generating extended hydrodynamic equations valid for both dense and rarefied gases. Howev…
Data-Driven Constitutive Relation Reveals Scaling Law for Hydrodynamic Transport Coefficients
Candi Zheng, Yang Wang, Shiyi Chen
Finding extended hydrodynamics equations valid from the dense gas region to the rarefied gas region remains a great challenge. The key to success is to obtain accurate constitutive…
A Family Group of Two-dimensional Node-Line Semimetals
Yuanjun Jin, Rui Wang, Jinzhu Zhao +5
Using evolutionary algorithm and first-principles calculations, we predict a family group of two-dimensional node-line semimetals MX (M=Pd, Pt; X=S, Se, Te), which has zig-zag type…
