To found security events from web logs has become an important aspect of network security. This paper proposes a website anomaly detection model based on security-log-analysis. After creating a anomaly feature sets of the model, C4.5 algorithm was used to improve feature sets, making the abnormal records in feature sets store hierarchically. Compared logs in website with the treated feature stes,...
In this paper, an improved Locally Linear Embedding method is proposed and used in the multi-pose ear recognition. In the traditional LLE method, the neighbors of a data point are selected by using k-nearest neighbor algorithm or e-nearest neighbor algorithm. Both of these methods neglect the different neighborhood of each data point and use a uniform way to select neighbors which leads to the sensitiveness...
Studies on gait recognition are mostly based on the assumption that walking direction is parallel to the camera, and the person's side view is extracted. Walking direction has becoming one of the gait recognition challenge problems. In this paper we explore gait recognition considering any directions of walking which is not definitely parallel to the camera. We propose a novel approach to computing...
