It is important to correctly and efficiently map drugs and enzymes to their possible interaction network in modern drug research. In this work, a novel approach was introduced to encode drug and enzyme molecules with physicochemical molecular descriptors and pseudo amino acid composition, respectively. Based on this encoding method, Random Forest was adopted to build the drug–enzyme interaction network...
This project's purpose is to give some ideas of Completely Automated Turing Test to Tell Computers and Humans Apart(CAPTCHA), an automatically Turing test which tell human and machine apart, vulnerabilities and its state of the art. As you know, CAPTCHAs are popular in network security area and has been lasting for nearly ten years. However, more and more schemes are suffering successful attacks....
The implementation of learning activity in online teaching directly influences the online learning quality. In this paper, we discussed the design of learning activity in online teaching, and conducted step design according to the learning activity designing pattern. And finally, we carried out a case study in order to explore how to improve online teaching quality.
An integrated technology of top-down and bottom-up visual attention used to the solution of the feature selection and saliency detection problems in object extraction and categorization of natural scene images is proposed. A decision criterion based on the top-down, goal-driven component is introduced to select the features of desired detection object which best distinguish the object from the other...
