Domain Adaption for Knowledge Tracing

no code implementations14 Jan 2020 Song Cheng, Qi Liu, Enhong Chen

We refer to this problem as domain adaptation for knowledge tracing (DAKT) which contains two aspects: (1) how to achieve great knowledge tracing performance in each domain.

Enhancing Item Response Theory for Cognitive Diagnosis

1 code implementation27 May 2019 Song Cheng, Qi Liu

However, traditional IRT ignores the rich information in question texts, cannot diagnose knowledge concept proficiency, and it is inaccurate to diagnose the parameters for the questions which only appear several times.

Compressing deep neural networks by matrix product operators

1 code implementation11 Apr 2019 Ze-Feng Gao, Song Cheng, Rong-Qiang He, Z. Y. Xie, Hui-Hai Zhao, Zhong-Yi Lu, Tao Xiang

A deep neural network is a parametrization of a multilayer mapping of signals in terms of many alternatively arranged linear and nonlinear transformations.

Tree Tensor Networks for Generative Modeling

no code implementations8 Jan 2019 Song Cheng, Lei Wang, Tao Xiang, Pan Zhang

Matrix product states (MPS), a tensor network designed for one-dimensional quantum systems, has been recently proposed for generative modeling of natural data (such as images) in terms of `Born machine'.

Information Perspective to Probabilistic Modeling: Boltzmann Machines versus Born Machines

no code implementations12 Dec 2017 Song Cheng, Jing Chen, Lei Wang

We compare and contrast the statistical physics and quantum physics inspired approaches for unsupervised generative modeling of classical data.

Equivalence of restricted Boltzmann machines and tensor network states

1 code implementation17 Jan 2017 Jing Chen, Song Cheng, Haidong Xie, Lei Wang, Tao Xiang

Conversely, we give sufficient and necessary conditions to determine whether a TNS can be transformed into an RBM of given architectures.
