How to accurately estimate facial age is a difficult problem due to insufficiency of training data. In this paper, an effective approach is proposed to estimate facial age by means of extreme learning machine (ELM). In the proposed method, a set of features is randomly selected from the original features to consist of a feature subspace. Given an initial weight matrix, the training samples within...
The smartphone applications have taken place of the web browser and became the user's primary internet entrance. One application's popularity can be measured by its downloading times, and it is valuable for commercial advertising. Identifying app installation packages from network traffic is one of the most feasible approaches to collect these data. But asymmetric routing, incomplete capture and so...
We present a new method for handling data skews in the database operation, relation joins. Recently, Graphics Processing Units (GPU) has become popular among high performance computing research and is used to accelerate the execution of database operations. Various parallel algorithms are developed in the past years with emerging of multi -core processors. Coordinate Module Distribution (CMD) is originally...
The development of computer technology provides a possible to carry out remote identification for biological quarantine specimens effectively, while at the present stage, most of the identification methods are lack of real-time interaction which makes the identification cost a lot of time. In this paper, we study the key technologies of web-based real-time remote expert identification, mainly in three...
There are many problems in the construction of network education resource currently, such as the neglect of teaching needs, duplication and lack of system design. These problems restrict the development and spread of distance education, which must be resolved. Postmodernism draws extensively Behaviorism, Cognitivism, Constructivism and other learning theories. Postmodernism advocates the spirit of...
More and more applications are adopting peer-to-peer (P2P) technology. Skype is a P2P based, popular VoIP software. The software works almost seamlessly across Network Address Translations (NATs) and firewalls and has better voice quality than most IM applications. The communication protocol and source code of Skype are undisclosed. It uses high strength encryption and random port number selection,...
Nowadays, alien species have become a threat to human existence and social sustainable development. An effective way to prevent them from spreading is Inspection and Quarantine. Focusing on this subject, we design and implement a digital integrated service platform which serves the Inspection and Quarantine Bureau. Based upon the web services, the system realizes information exchange and sharing of...
