How likely is a random graph shift-enabled?
Liyan Chen, Samuel Cheng, Vladimir Stankovic +1
The shift-enabled property of an underlying graph is essential in designing distributed filters. This article discusses when a random graph is shift-enabled. In particular, popular…
Probabilistic Federated Learning of Neural Networks Incorporated with Global Posterior Information
Peng Xiao, Samuel Cheng
In federated learning, models trained on local clients are distilled into a global model. Due to the permutation invariance arises in neural networks, it is necessary to match the…
Implementing distributed graph filters by elementary matrix decomposition
Samuel Cheng
In this letter, we consider the implementation problem of distributed graph filters, where each node only has access to the signals of the current and its neighboring nodes. By usi…
Neural Network for NILM Based on Operational State Change Classification
Peng Xiao, Samuel Cheng
Energy disaggregation in a non-intrusive way estimates appliance level electricity consumption from a single meter that measures the whole house electricity demand. Recently, with…
Undirected graphs: is the shift-enabled condition trivial or necessary?
Liyan Chen, Samuel Cheng, Kanghang He +2
It has recently been shown that, contrary to the wide belief that a shift-enabled condition (necessary for any shift-invariant filter to be representable by a graph shift matrix) c…
Binary Rate Distortion With Side Information: The Asymmetric Correlation Channel Case
Andrei Sechelea, Samuel Cheng, Adrian Munteanu +1
Advancing over up-to-date information theoretic results that assume symmetric correlation models, in this work we consider the problem of lossy binary source coding with side infor…
Decomposition Approach for Low-rank Matrix Completion
Rick Ma, Samuel Cheng
In this paper, we describe a low-rank matrix completion method based on matrix decomposition. An incomplete matrix is decomposed into submatrices which are filled with a proposed t…
Hamming Code for Multiple Sources
Rick Ma, Samuel Cheng
We consider Slepian-Wolf (SW) coding of multiple sources and extend the packing bound and the notion of perfect code from conventional channel coding to SW coding with more than tw…
