A clustering model identification method based on the statistics has been proposed to improve the ability to detect scale anomaly behavior of the traditional anomaly detection technology. By analyzing the distribution of the distance between each clustering objects and clustering center to identify anomaly behavior. It ensures scale abnormal behavior identification while keeping the processing mechanism of the traditional anomaly detection technology for isolation, and breaking through the limitation of the traditional anomaly detection method assumes that abnormal data is the isolation. In order to improve the precision of clustering, we correct the Euclidean distance with the entropy value method to weight the attribute of the data, it optimizes the similarity evaluating electric of the nearest neighbor clustering algorithm, and simulated. Experimental results show that the statistical method and the improved clustering method is more efficient and self-adaptive.

In the current study, we tested whether representations in visual STM (VSTM) can be biased via top–down attentional modulation of visual activity in retinotopically specific locations. We manipulated attention using retrospective cues presented during the retention interval of a VSTM task. Retrospective cues triggered activity in a large-scale network implicated in attentional control and led to retinotopically specific modulation of activity in early visual areas V1–V4. Importantly, shifts of attention during VSTM maintenance were associated with changes in functional connectivity between pFC and retinotopic regions within V4. Our findings provide new insights into top–down control mechanisms that modulate VSTM representations for flexible and goal-directed maintenance of the most relevant memoranda.
