Light detection and ranging (LIDAR) is a technology of remote imaging technologies. Currently, it is the most important technology for accruing elevation points with a high density in the form of digital elevation model (DEM) construction. However, the high-density data leads to time and memory consumption problems during data processing. In this paper, we depend on radial basis function (RBF) with...
Preserving important troubleshooting experience gained in industrial practice, often referred to as “tribal knowledge”, and making it readily available to be re-applied in similar situations represent a serious challenge for many companies in heavy industry. The solution is very often tied to building mental models to capture and express key latent cognitive variables. In this paper, we first attempt...
Obtaining extractive summaries by using functions induced from a training set continue to be a great challenge in the domain of the automatic text summary. This paper presents the VENCE method based on this approach and improves the quality of the abduced functions, using semantic relations of the words (attributes) of the training set that are fetched from a ontology to be inserted in this set. The...
In this paper we describe the second stage of developing new Situation Awareness Training and investigation of its effectiveness on improving cognitive intercommunication with e-learning system. Situation Awareness training enhance of attentiveness as well as increase of exam's GPA and nonverbal intelligence indexes had been observed. Improvement of the exam results, mediated by attention increase,...
This paper proposes a novel extension on Non-negative Matrix Factorization (NMF) scheme for the separation of single channel speech mixtures, where we impose a post-sparse model on the original weight matrix derived from a previously proposed coherence-constrained NMF model. The approach considers both the modeling ability of NMF basis functions for each source as well as the ability of these basis...
Affective computing research field is growing in large scale with the frequent development of human-computer applications. These applications use information of mental or affective conditions of desired subjects to train their brain responses. Facial impressions, text physiology, vocal and other information about the subjects are used in the classification algorithms. However, the classification frameworks...
Accurate detection of voids in solder bumps on ball grid arrays (BGAs) is important for improving device quality. Radiographic imaging is commonly used to inspect BGA packages incorporate into LSI circuits. In the case of conventional method, imaging is normally done four times, and the images obtained are averaged to reduce noises. We have developed a nonnegative matrix factorization method for detecting...
Hiding and seeking are cognitive abilities frequently demonstrated by humans in both real life and video games. To determine to which extent these abilities can be replicated with AI, we introduce a specialized version of the Turing test for hiding and seeking. We then develop a computer agent that passes the test by appearing indistinguishable from human behavior to a panel of human judges. We analyze...
Chinese word segmentation (CWS) can be transformed into word-position-based approaches by conditional random field (CRF). It improved the performance of Chinese word segmentation greatly which makes it in wide use recently. When training on corpus with CRF, the size of feature window is the key to the training effect. To analyze the effect range of context, string sequence tagging segmentations are...
We previously proposed the accumulation method, which is a language-independent text classification method that is based on the character N-gram, and classified English, Japanese, and Korean text documents. The accumulation method does not depend on the language structure, because this method uses the character N-gram to form index terms. If text documents are expressed in Unicode, then the accumulation...
Analytic hierarchy process (AHP) is a conjoint effective assessing method which combines qualitative and quantitative analysis. Since it is uncertain in the process of deal with qualitative object quatificationally. In order to improve the reliability, the process should be improved in appropriate theories and methods. The weight evaluation method is presented combining AHP and computer technology...
Digital micro system is a digital network system which sets the Micro teaching, multimedia editing, film video production, multimedia storage, video on demand, digital broadcast live as one. But as applied technology, combining audio visual technology with educational theory, the micro-teaching model plays an important role in school teaching. This thesis, with the martial art teaching as an example,...
On the basis of some research work about the educational evaluation index system of electronic games,we establish an educational evaluation system for electronic games using BP neural network model.The system has self-learning and adaptive characteristics.After the BP neural network trained with the expert knowledge,it not only has the experience of experts, but also realizes the changes from the...
The purpose of the research were 1) to analyze, to design and to development ISO 9000 multimedia training package, 2) to evaluate the efficiency of multimedia training package, 3) the learning effectiveness, and 4) learner's satisfaction towards the multimedia training package. The research tools were 1) The development of ISO 9000 multimedia training package. 2) Achievement tests. 3) The questionnaire...
To cultivate college students' innovative consciousness and practical ability is an important task of personnel training in colleges and universities. This paper constructs an evaluation index system of computer specialty students' practical innovation ability, including the basis of professional expertise, extra-curricular practical ability, the overall quality of innovation and so on. This paper...
An improved neural network based on L-M (Levenberg-Marquard) algorithm neural network has been applied to the model for the analysis of factors on Hypertension. It can remedy the shortcoming of the slow convergence rate of traditional BP algorithm neural network. This model can determine which factors are the main reasons for high blood pressure. We have adopted the lattice fuzzy close-degree assessment...
This paper introduces the meaning of the information literacy and the status and the analysis of the information literacy and scientific research ability of the college teachers, finally the author puts forward the counter-measures.
This thesis discusses the evaluation function of college teacher's ability of using information technology including oriented function, inspiring function and ensuring function, and establishes the evaluation index system including information ideals, information circumstances, basic knowledge, using ability and effects. This thesis studies its index sequence and weight with Analytic Hierarchy Process...
In this paper we present an automatic hand gesture recognition system operating on video stream. The system consists of two modules: hand gesture detection module and hand gesture recognition module. The detection module could accurately locate the hand regions with a blue rectangle; this is mainly based on Viola-Jones method, which is currently considered the fastest and most accurate learning-based...
In order to evaluate the bilingual instructing process and help the university acquire timely feedback information from students, a Bilingual Teaching Evaluation System based on BP neural network is established. Based on the investigation and analysis of the bilingual instructing process in Nanchang University, an evaluation index system is built, which consists of 14 indices. Take the 14 evaluation...
