Provable Tensor Completion with Graph Information

no code implementations4 Oct 2023 Kaidong Wang, Yao Wang, Xiuwu Liao, Shaojie Tang, Can Yang, Deyu Meng

For the model, we establish a rigorous mathematical representation of the dynamic graph, based on which we derive a new tensor-oriented graph smoothness regularization.

An interpretable neural network model through piecewise linear approximation

no code implementations20 Jan 2020 Mengzhuo Guo, Qingpeng Zhang, Xiuwu Liao, Daniel Dajun Zeng

To address these issues, we propose a hybrid interpretable model that combines a piecewise linear component and a nonlinear component.

Explainable Ordinal Factorization Model: Deciphering the Effects of Attributes by Piece-wise Linear Approximation

no code implementations14 Nov 2019 Mengzhuo Guo, Zhongzhi Xu, Qingpeng Zhang, Xiuwu Liao, Jiapeng Liu

Ordinal regression predicts the objects' labels that exhibit a natural ordering, which is important to many managerial problems such as credit scoring and clinical diagnosis.

A preference learning framework for multiple criteria sorting with diverse additive value models and valued assignment examples

no code implementations12 Oct 2019 Jiapeng Liu, Milosz Kadzinski, Xiuwu Liao, Xiaoxin Mao, Yao Wang

We propose an optimization model for constructing a preference model from such valued examples by maximizing the credible consistency among reference alternatives.

A hybrid machine learning framework for analyzing human decision making through learning preferences

no code implementations4 Jun 2019 Mengzhuo Guo, Qingpeng Zhang, Xiuwu Liao, Frank Youhua Chen, Daniel Dajun Zeng

To meet the decision maker's demand for more interpretable machine learning models, we propose a novel hybrid method, namely Neural Network-based Multiple Criteria Decision Aiding, which combines an additive value model and a fully-connected multilayer perceptron (MLP) to achieve good performance while capturing the explicit relationships between individual attributes and the prediction.

Data-driven preference learning methods for value-driven multiple criteria sorting with interacting criteria

no code implementations21 May 2019 Jiapeng Liu, Milosz Kadzinski, Xiuwu Liao, Xiaoxin Mao

We also propose a few novel methods for classifying non-reference alternatives in order to enhance the applicability of our approach to different datasets.
