Pretrained Cost Model for Distributed Constraint Optimization Problems

1 code implementation8 Dec 2021 Yanchen Deng, Shufeng Kong, Bo An

Our model, GAT-PCM, is then pretrained with optimally labelled data in an offline manner, so as to construct effective heuristics to boost a broad range of DCOP algorithms where evaluating the quality of a partial assignment is critical, such as local search or backtracking search.

Gaussian Mixture Variational Autoencoder with Contrastive Learning for Multi-Label Classification

1 code implementation2 Dec 2021 Junwen Bai, Shufeng Kong, Carla P. Gomes

We find that by using contrastive learning in the supervised setting, we can exploit label information effectively in a data-driven manner, and learn meaningful feature and label embeddings which capture the label correlations and enhance the predictive power.

Materials Representation and Transfer Learning for Multi-Property Prediction

2 code implementations4 Jun 2021 Shufeng Kong, Dan Guevarra, Carla P. Gomes, John M. Gregoire

To address these issues, we introduce the Hierarchical Correlation Learning for Multi-property Prediction (H-CLMP) framework that seamlessly integrates (i) prediction using only a material's composition, (ii) learning and exploitation of correlations among target properties in multi-target regression, and (iii) leveraging training data from tangential domains via generative transfer learning.
