Accelerating Inverse Learning via Intelligent Localization with Exploratory Sampling

1 code implementation2 Dec 2022 Jiaxin Zhang, Sirui Bi, Victor Fung

In the scope of "AI for Science", solving inverse problems is a longstanding challenge in materials and drug discovery, where the goal is to determine the hidden structures given a set of desirable properties.

Atomic structure generation from reconstructing structural fingerprints

1 code implementation27 Jul 2022 Victor Fung, Shuyi Jia, Jiaxin Zhang, Sirui Bi, Junqi Yin, P. Ganesh

These methods would help identify or, in the case of generative models, even create novel crystal structures of materials with a set of specified functional properties to then be synthesized or isolated in the laboratory.

A Hybrid Gradient Method to Designing Bayesian Experiments for Implicit Models

no code implementations14 Mar 2021 Jiaxin Zhang, Sirui Bi, Guannan Zhang

However, the approach in Kleinegesse et al., 2020 requires a pathwise sampling path to compute the gradient of the MI lower bound with respect to the design variables, and such a pathwise sampling path is usually inaccessible for implicit models.

A Scalable Gradient-Free Method for Bayesian Experimental Design with Implicit Models

no code implementations14 Mar 2021 Jiaxin Zhang, Sirui Bi, Guannan Zhang

However, the approach requires a sampling path to compute the pathwise gradient of the MI lower bound with respect to the design variables, and such a pathwise gradient is usually inaccessible for implicit models.

Scalable Deep-Learning-Accelerated Topology Optimization for Additively Manufactured Materials

no code implementations28 Nov 2020 Sirui Bi, Jiaxin Zhang, Guannan Zhang

Unlike the existing studies of DL for TO, our framework accelerates TO by learning the iterative history data and simultaneously training on the mapping between the given design and its gradient.

Robust data-driven approach for predicting the configurational energy of high entropy alloys

no code implementations10 Aug 2019 Jiaxin Zhang, Xianglin Liu, Sirui Bi, Junqi Yin, Guannan Zhang, Markus Eisenbach

In this study, a robust data-driven framework based on Bayesian approaches is proposed and demonstrated on the accurate and efficient prediction of configurational energy of high entropy alloys.
