With the increase of colorectal cancer patients in recent years, the needs of quantitative evaluation of colorectal cancer are increased, and the computer-aided diagnosis (CAD) system which supports doctor's diagnosis is essential. In this paper, a hardware design of type identification module in CAD system for colorectal endoscopie images with narrow band imaging (NBI) magnification [1] is proposed...
Todays, feature selection is an active research in machine learning. The main idea of feature selection is to select a subset of available features, by eliminating features with little or no predictive information. This paper presents a hybrid model with a new local search technique based on reinforcement learning for feature selection. We combined the particle swarm optimization (PSO) with support...
In addition to provide charging service, Electric Vehicle (EV) charging station equipped with distributed energy storage system can also participate in the deregulate market to optimize the cost of operation. To support this function, it is necessary to achieve sufficient accuracy on the forecasting of energy resources and market prices. The deregulated market price prediction presents challenges...
Wrist pulse signal is believed to contain critical information of the patients' health condition. This project aims to analyze the time series wrist pulse signals in order to distinguish patients suffering from various symptoms with healthy people. In this paper, the four inflammation symptoms tackled in this project are Appendicitis (A), Acute Appendicitis (AA), Pancreatitis (P) and Duodenal Bulb...
In this paper, we propose a system of automatically classifying different types of dates from their images. Different dates have various distinguished features that can be useful to recognize a particular date. These features include color, texture, and shape. In the proposed system, a color image of a date is decomposed into its color components. Then, local texture descriptor in the form of local...
The ability to acquire Electroencephalogram (EEG) signals from the brain has led to the development of Brain Computer Interfaces (BCI), which capture signals generated by the physical processes in the brain and use them to control external devices. In this paper, we establish an application to control a robot on the Arduino platform by the use of a BCI system, which does not require training for individual...
Website response time is one of the most important performance parameter of website. It can be used to assess website performance to forecast the status of website. Large amounts of data are applied by a distributed monitoring system that monitoring a university website response time. Support vector machine with information granulation is studied to predict the response time. It can predict accurately...
Monitoring and classification of human activity has been an active area of research for the past few years due to the increasing demands in healthcare sector. Quick aid for falls in elderly persons and detecting emergency situations are few leading cause of such interest. In this paper, a human activity recognition system based on motion patterns on a smartphone is proposed for classification of activities...
Quran is the holy book for Muslims around the world. Since it was revealed to the Prophet Muhammad (PBUH) before about 14 hundreds years, Quran is preserved in all imaginable ways from distortion. The rapid and huge growth of digital media and internet usage, cause a wide spread of the Quranic knowledge as well as Quranic Verses, scripts, Translations, and many other Quranic sciences in its digital...
Classification strategy is an important issue of support vector machine application. Aiming at the defects of common used classification methods, an improved minimum spanning tree support vector machine (MST-SVM) is proposed. MST-SVM has the advantages of simple structure and high classification efficiency. The classification process is further optimized by introduction of Fisher separability measure...
Wrist pulse signals contain important information about the health of a person and hence diagnosis based on pulse signals has assumed great importance. In this paper we demonstrate the efficacy of a two term Gaussian model to extract information from pulse signals. Results have been obtained by conducting experiments on several subjects to record wrist pulse signals for the cases of before exercise...
Night video surveillance is crucial to construct an all-weather video surveillance system. However, night video surveillance faces several problems: no color information, low brightness, low contrast, and low signal to noise ratio (SNR). These problems can introduce serious false and missing object detections. In this paper, we propose a novel night video surveillance method based on the image second-order...
In classification with Support Vector Machines, only Mercer kernels, i.e. valid kernels, such as the Gaussian RBF kernel, are widely accepted and thus suitable for clinical data. Practitioners would also like to use the sigmoid kernel, a non-Mercer kernel, but its range of validity is difficult to determine, and even within range its validity is in dispute. Despite these shortcomings the sigmoid kernel...
Breast cancer is the most common malignant tumor for women. In the past twenty years, the incidence of breast cancer continues to rise. Then, the diagnosis and treatment of the breast cancer have become an extremely urgent work to do. In this study, we intend to build a diagnostic model of breast cancer by using data mining techniques. A feature selection method, INTERACT is applied to select relevant...
Previously, we investigated the prediction of total effort and errors for embedded software development projects using an artificial neural network (ANN). In addition, we proposed a method for reducing this margin of error. However, methods using ANNs have reached their improvement limits, since an appropriate value is estimated using what is known as point estimation in statistics. In this paper,...
Customer reviews are important sources of opinions of customers. The reviews contain some sentence pattern and some sort of patterns will be useful to extract the opinions of the customers easily. We propose a method to classify customer reviews using estimation expression patterns by support vector machine. We confirm an effectiveness of the proposed method by experimental results.
The present study proposes prediction approaches of student's grade based on their comments data. Students describe their learning attitudes, tendencies and behaviors by writing their comments freely after each lesson. The main difficulty of this research is to predict students' performance by separately using two class data in each lesson. Although students learn the same subject, there exist differences...
One of the most important applications of remote sensing in urban area is impervious surface information extraction. Previous research has shown that satellite imagery has the potential and advantage for impervious surface estimating. In particular, the high resolution imagery, which has a spatial resolution in the meter to sub-meter range, is very useful for high accuracy mapping and monitoring of...
Landsat acquires the longest space-based moderateresolution land remote sensing images continuously. Compared with the other earlier Landsat satellites, Landsat 8 has several new characteristics in spectral bands, spectral range and radiometric resolution. Therefore, there is a strong requirement to analyze the characteristics of the Landsat 8 for land cover classification, global change research...
