An Incremental Phase Mapping Approach for X-ray Diffraction Patterns using Binary Peak Representations

1 code implementation8 Nov 2022 Dipendra Jha, K. V. L. V. Narayanachari, Ruifeng Zhang, Justin Liao, Denis T. Keane, Wei-keng Liao, Alok Choudhary, Yip-Wah Chung, Michael Bedzyk, Ankit Agrawal

Despite the huge advancement in knowledge discovery and data mining techniques, the X-ray diffraction (XRD) analysis process has mostly remained untouched and still involves manual investigation, comparison, and verification.

A real-time iterative machine learning approach for temperature profile prediction in additive manufacturing processes

no code implementations28 Jul 2019 Arindam Paul, Mojtaba Mozaffar, Zijiang Yang, Wei-keng Liao, Alok Choudhary, Jian Cao, Ankit Agrawal

As the process for creating an intricate part for an expensive metal such as Titanium is prohibitive with respect to cost, computational models are used to simulate the behavior of AM processes before the experimental run.

IRNet: A General Purpose Deep Residual Regression Framework for Materials Discovery

2 code implementations7 Jul 2019 Dipendra Jha, Logan Ward, Zijiang Yang, Christopher Wolverton, Ian Foster, Wei-keng Liao, Alok Choudhary, Ankit Agrawal

We use the problem of learning properties of inorganic materials from numerical attributes derived from material composition and/or crystal structure to compare IRNet's performance against that of other machine learning techniques.

Transfer Learning Using Ensemble Neural Networks for Organic Solar Cell Screening

1 code implementation7 Mar 2019 Arindam Paul, Dipendra Jha, Reda Al-Bahrani, Wei-keng Liao, Alok Choudhary, Ankit Agrawal

In this work, we present an ensemble deep neural network architecture, called SINet, which harnesses both the SMILES and InChI molecular representations to predict HOMO values and leverage the potential of transfer learning from a sizeable DFT-computed dataset- Harvard CEP to build more robust predictive models for relatively smaller HOPV datasets.

CheMixNet: Mixed DNN Architectures for Predicting Chemical Properties using Multiple Molecular Representations

3 code implementations14 Nov 2018 Arindam Paul, Dipendra Jha, Reda Al-Bahrani, Wei-keng Liao, Alok Choudhary, Ankit Agrawal

SMILES is a linear representation of chemical structures which encodes the connection table, and the stereochemistry of a molecule as a line of text with a grammar structure denoting atoms, bonds, rings and chains, and this information can be used to predict chemical properties.

A DEEP ADVERSARIAL LEARNING METHODOLOGY FOR DESIGNING MICROSTRUCTURAL MATERIAL SYSTEMS

1 code implementation26 Aug 2018 Xiaolin Li, Zijiang Yang, L. Catherine Brinson, Alok Choudhary, Ankit Agrawal, Wei Chen

Due to the special design of the network architecture, the proposed methodology is able to identify the latent (design) variables with desired dimensionality, as well as capturing complex material microstructural characteristics.

An exploration of parameter redundancy in deep networks with circulant projections

no code implementations ICCV 2015 Yu Cheng, Felix X. Yu, Rogerio S. Feris, Sanjiv Kumar, Alok Choudhary, Shih-Fu Chang

We explore the redundancy of parameters in deep neural networks by replacing the conventional linear projection in fully-connected layers with the circulant projection.

Temporal Sequence Modeling for Video Event Detection

no code implementations CVPR 2014 Yu Cheng, Quanfu Fan, Sharath Pankanti, Alok Choudhary

Based on this idea, we represent a video by a sequence of visual words learnt from the video, and apply the Sequence Memoizer [21] to capture long-range dependencies in a temporal context in the visual sequence.
