High-Dimensional Uncertainty Quantification via Tensor Regression with Rank Determination and Adaptive Sampling

no code implementations31 Mar 2021 Zichang He, Zheng Zhang

Recently, low-rank tensor methods have been developed to mitigate this issue, but two fundamental challenges remain open: how to automatically determine the tensor rank and how to adaptively pick the informative simulation samples.

Active Sampling for Accelerated MRI with Low-Rank Tensors

no code implementations23 Dec 2020 Zichang He, Bo Zhao, Zheng Zhang

In this paper, we introduce an active low-rank tensor model for fast MR imaging.

An evidential Markov decision making model

no code implementations10 May 2017 Zichang He, Wen Jiang

However, the state is allowed to be uncertain in the EM model before the final decision is made.

Quantum Mechanical Approach to Modelling Reliability of Sensor Reports

no code implementations17 Apr 2017 Zichang He, Wen Jiang

Dempster-Shafer evidence theory is wildly applied in multi-sensor data fusion.

A quantum dynamic belief model to explain the interference effects of categorization on decision making

no code implementations6 Mar 2017 Zichang He, Wen Jiang

However, the categorization process may interfere the decision making result and the law of total probability can be violated in some situations.

Evidential supplier selection based on interval data fusion

no code implementations6 Mar 2017 Zichang He, Wen Jiang

However, the weights of criteria are kept as interval numbers to generate interval BPAs and do the fusion of interval BPAs.

A new belief Markov chain model and its application in inventory prediction

no code implementations6 Mar 2017 Zichang He, Wen Jiang

The new belief Markov chain model overcomes the shortcomings of classical Markov chain and has an efficient ability in dealing with uncertain information.

A quantum dynamic belief decision making model

no code implementations6 Mar 2017 Zichang He, Wen Jiang

The uncertainty in actions is represented as an extra uncertainty state.
