Anomaly Detection on IT Operation Series via Online Matrix Profile
Shi-Ying Lan, Run-Qing Chen, Wan-Lei Zhao
Anomaly detection on time series is a fundamental task in monitoring the Key Performance Indicators (KPIs) of IT systems. Many of the existing approaches in the literature show goo…
Towards Accurate Localization by Instance Search
Yi-Geng Hong, Hui-Chu Xiao, Wan-Lei Zhao
Visual object localization is the key step in a series of object detection tasks. In the literature, high localization accuracy is achieved with the mainstream strongly supervised…
Large-Scale Approximate k-NN Graph Construction on GPU
Hui Wang, Wan-Lei Zhao, Xiangxiang Zeng
k-nearest neighbor graph is a key data structure in many disciplines such as manifold learning, machine learning and information retrieval, etc. NN-Descent was proposed as an effec…
k-sums: another side of k-means
Wan-Lei Zhao, Run-Qing Chen, Hui Ye +1
In this paper, the decades-old clustering method k-means is revisited. The original distortion minimization model of k-means is addressed by a pure stochastic minimization procedur…
Dynamic Sampling for Deep Metric Learning
Chang-Hui Liang, Wan-Lei Zhao, Run-Qing Chen
Deep metric learning maps visually similar images onto nearby locations and visually dissimilar images apart from each other in an embedding manifold. The learning process is mainl…
Deeply Activated Salient Region for Instance Search
Hui-Chu Xiao, Wan-Lei Zhao, Jie Lin +1
The performance of instance search depends heavily on the ability to locate and describe a wide variety of object instances in a video/image collection. Due to the lack of proper m…
