Our group recommender system was targeted at a scenario that requires the adoption of group recommendation techniques to conserve computational resources. The profile aggregation strategy was used in our work to implement this group recommendation system. Key to our work, user clustering is also the first step of our work. The accuracy of user clustering could be improved once we processed the data...
The score in art exam, part of College entrance examination, is very useful and helpful. Thanks to the exam management system we got the data easily, and there are huge amount of data accumulated. We analyzed the data and visualize the data through Cluster Analysis and Correlation Analysis. And get the relationship between number of students and age, subject, position. Finally we visualize the analyzed...
With the development of artificial intelligence technology over several decades, it is getting possible to find useful knowledge from an enormous amount of data. Also, it is getting possible to solve the difficult problems which cannot be solved by a human prover. Actually, a Japanese research project called "Todai Robot Project" tries to develop an intelligent robot that passes an entrance...
In the current Internet system, there are many problems using anonymity of the network communication such as personal information leaks and crimes using the Internet system. This is why TCP/IP protocol used in Internet system does not have the user identification information on the communication data, and it is difficult to supervise the user performing the above acts immediately. As a study for solving...
Different scholar hold different views with the relationship of international capital flows and economic growth. By China international capital flows on economic growth influence the empirical analysis, this article believes that the international capital flows on economic growth exist both positive effect and negative effect.
In this study, we aimed to develop a dragonfly-like flapping robot with four wings and achieve advanced flight such as hovering and sudden turn. We developed a two-wings-flapping-robot that links the flapping motion moving the wing up and down and feathering motion twisting the wing and perform at the same time. Next, we investigated the performance of the developed robot whether it's possible to...
Recently Lu et al. proposed a modified anonymous two-factor authenticated key exchange protocol to eliminate the security weaknesses of Xie et al.'s scheme. They hence claimed that their scheme is immune to possible well-known attacks. However, we found that Lu et al.'s protocol is still insecure against the outsider attack, user impersonation attack, and off-line password guessing attack. To overcome...
With the development of information technology, the Smart Laboratory is an core research topic of the modern university, which is responsible for the laboratory safety. To this problem, we focus on the human management since many safety accidents are often occurred by improper operations. This paper proposes the concept of security credit, which consists of user characteristic, behavior preference,...
Recommendation system has been applied in many fields, such as Human Computer Interaction, Information Retrieval, and so on. Essentially speaking, these are based on data mining. Among the many algorithms used in the recommendation system, collaborative filtering algorithm is one of the most mature and most widely used algorithm. With the coming of big data era, a variety of recommendation algorithm...
Animation rendering node is the key component of distributed animation rendering system, which offers rendering service. The performance of animation rendering node has great impact on user's experience. This paper uses DTMC-based model checking methodology to evaluate animation rendering node's performance. Based on the analysis of animation rendering node's working process, the probability of steady-state...
Music recognition is more and more widely used in our life. This paper presents a music identification system based on audio fingerprinting. In this paper, a set of music recognition system based on the audio fingerprint is designed, which is based on the audio fingerprint, and constructs the audio fingerprint database to realize the function application of the target music recognition. The system...
In today's internet era, people are facing huge amount of information, that is the so called information overloading. It has hampered people to make full use the convenience of the Internet. There are several ways to solve the problem, such as category list, search engine and re-commendation engine. Among them search engine and recommendation engine are more popular. In real situation a recommendation...
Dimension reduction of data is an important theme in the data processing and on the web to represent and manipulate higher dimensional data. Rough set is fundamental and useful to process higher dimensional data. Reduct in the rough set is a minimal subset of features, which has the same discernible power as the entire features in the higher dimensional scheme. It is shown that nearest neighbor relation...
Bio-signals as electroencephalography (EEG) has been studied extensively in clinical and cognitive neurosciences. Recently, neurofeedback(NFB) is discussed as a type of biofeedback that measures brain waves(EEG) to produce a signal that can be used as feedback to teach self-regulation(self-control) of brain function. The neurofeedback has drawn much attention as a self-control training for children...
The custom to gaze at screens of PC and smart phones has become common in daily life and it causes increase the symptom of dry eye syndrome. The purpose of this study is to develop a new monitor system to catch an eye area by using a front camera of a tablet, to visualize the opening and closing rate of the blink and to reduce eyestrain and to alert dry eye syndrome. Then, the image processing techniques...
A lot of data are collected through various kind of sensors and devices and can be used to make business strategy. These are sometimes used in business and marketing. In existing convention management research and its business research, most of contributions provide the result of analyses of surveys using answer of questionnaire or interviews from convention attendees, event planners and several other...
This paper discusses the effect of classification in estimating the amount of effort (in man-days) associated with code development. Estimating the effort requirements for new software projects is especially important. As outliers are harmful to the estimation, they are excluded from many estimation models. However, such outliers can be identified in practice once the projects are completed, and so...
The magnetic measurement of large objects suchas the air cargo fixes magnetic sensor and we move an object andmeasure the amount of change. In this case, in a device movingan object, a problem occurs. It is a problem of the strength ofmaterials and the manufacture cost. Therefore the manufacturerasks the specialized company for the magnetic measurement ofthe large object in many cases. However, in...
