Unsupervised Heterogeneous Coupling Learning for Categorical Representation
Chengzhang Zhu, Longbing Cao, Jianping Yin
Complex categorical data is often hierarchically coupled with heterogeneous relationships between attributes and attribute values and the couplings between objects. Such value-to-o…
Understand Dynamic Regret with Switching Cost for Online Decision Making
Yawei Zhao, Qian Zhao, Xingxing Zhang +3
As a metric to measure the performance of an online method, dynamic regret with switching cost has drawn much attention for online decision making problems. Although the sublinear…
Simultaneous Clustering and Optimization for Evolving Datasets
Yawei Zhao, En Zhu, Xinwang Liu +3
Simultaneous clustering and optimization (SCO) has recently drawn much attention due to its wide range of practical applications. Many methods have been previously proposed to solv…
Dynamic Online Gradient Descent with Improved Query Complexity: A Theoretical Revisit
Yawei Zhao, En Zhu, Xinwang Liu +1
We provide a new theoretical analysis framework to investigate online gradient descent in the dynamic environment. Comparing with the previous work, the new framework recovers the…
Triangle Lasso for Simultaneous Clustering and Optimization in Graph Datasets
Yawei Zhao, Kai Xu, Xinwang Liu +3
Recently, network lasso has drawn many attentions due to its remarkable performance on simultaneous clustering and optimization. However, it usually suffers from the imperfect data…
