Text Categorization (TC) is a task of classifying a set of documents into one or more predefined categories. Centroid-based method, a very popular TC method, aims to make classifiers simple and efficient by constructing one prototype vector for each class. It classifies a document into the class that owns the prototype vector nearest to the document. Many studies have been done on constructing prototype vectors. However, the basic philosophies of these methods are quite different from each other

Quantum fully homomorphicencryption scheme based on universal quantum circuit

Research on Time Synchronization and Flow Aggregation in LDDoS Attack Based on Cross-correlation

An improved FCM medical image segmentation algorithm based on MMTD

Network security policy and the automated refinement of its hierarchies aims to simplify the administration of security services in complex network environments. The semantic gap between the policy hierarchies reflects the validity of the policy hierarchies yielded by the automated policy refinement

This paper presents VINCE - a novel Visible Light Communication (VLC) system for smartphones. VINCE encodes information as different brightness levels of smartphone screens, while receivers capture the light signal via light sensors. We experimentally profile the impact of screen brightness levels and refresh rates of smartphones, and then use the results to guide the design of light intensity encoding scheme of VINCE. We adopt several signal processing techniques and empirically derive a model
