Speaker role clustering is to obtain the number of different roles and to merge the utterances of the same role into one cluster in an unsupervised way, which is important for rich transcription of multi-speaker spoken documents. This paper presents an approach to role clustering using turn features and maximum distances of inter-clusters. The turn features of each speaker are extracted from audio...
Object detection is a hot spot of the research in computer vision since many applications require the determination of the object location. There are many object detection methods based on feature matching methods. In this paper, we locate object on robot operation system. The SIFT keypoints of the template and test images are extracted at first. Then, the matching method is proposed to find the template...
The automatic generation of malicious behavior pattern based on system call trace is important to malware detection. This paper studied the existing generation method of malicious behavior specification. In order to reduce the complexity of pattern generation, it constructs graph which vertex label is unique, and uses these graphs to mine the pattern. To address the issue of limitation of the minimal...
