Online Graph Learning in Dynamic Environments
Xiang Zhang
Inferring the underlying graph topology that characterizes structured data is pivotal to many graph-based models when pre-defined graphs are not available. This paper focuses on le…
Learning Geo-Contextual Embeddings for Commuting Flow Prediction
Zhicheng Liu, Fabio Miranda, Weiting Xiong +3
Predicting commuting flows based on infrastructure and land-use information is critical for urban planning and public policy development. However, it is a challenging task given th…
Unsupervised Classification of Street Architectures Based on InfoGAN
Ning Wang, Xianhan Zeng, Renjie Xie +5
Street architectures play an essential role in city image and streetscape analysing. However, existing approaches are all supervised which require costly labeled data. To solve thi…
A Deep, Information-theoretic Framework for Robust Biometric Recognition
Renjie Xie, Yanzhi Chen, Yan Wo +1
Deep neural networks (DNN) have been a de facto standard for nowadays biometric recognition solutions. A serious, but still overlooked problem in these DNN-based recognition system…
Calibration of a two-state pitch-wise HMM method for note segmentation in Automatic Music Transcription systems
Dorian Cazau, Yuancheng Wang, Olivier Adam +2
Many methods for automatic music transcription involves a multi-pitch estimation method that estimates an activity score for each pitch. A second processing step, called note segme…
The Sum Rate of Vector Gaussian Multiple Description Coding with Tree-Structured Covariance Distortion Constraints
Yinfei Xu, Jun Chen, Qiao Wang
A single-letter lower bound on the sum rate of multiple description coding with tree-structured distortion constraints is established by generalizing Ozarow's celebrated converse a…
Rate Region of the Vector Gaussian CEO Problem with the Trace Distortion Constraint
Yinfei Xu, Qiao Wang
We establish a new extremal inequality, which is further leveraged to give a complete characterization of the rate region of the vector Gaussian CEO problem with the trace distorti…
