One of the popular features extraction methods for recognizing motor imagery EEG signal is Common Spatial Pattern (CSP). CSP is an algorithm that maximize the variance of one class and minimize the variance of other class simultaneously to discriminate two classes of multichannel EEG signals for classification purpose. However, CSP assumes that the signals on all EEG channels are functionally interconnected...
In the era of the development of mobile technology, direct communication becomes a rare thing between humans to their families, causing the spatial communication between families, be it close family, distant family, or extended family. This can lead to familial relationships disappear, so that the grandchildren do not know their family tree properly. The “Geni.com” app provides a feature to record...
This paper explains the gender recognition system through a human facial image by using the basic method of Principal Component Analysis (PCA) combined with Linear Discriminant Analysis (LDA). PCA+LDA method performance can be improved by improvising the preprocessing techniques such as resizing the image, equalizing the histogram, and removing the variation of the image background by adding oval...
Machinery equipment early fault detection is still in an open challenge. The objective of this paper is to introduce a parametric method Artificial Neural Network based Autoencoder implemented to perform early fault detection of a machinery equipment. The performance of this method is then compared to one of the industry state of the art nonparametric methods called Similarity Based Modeling. The...
Machine learning algorithm can be applied for automating soil type classification. This paper compares several machine learning algorithms for classifying soil type. Algorithms that involve support vector machine (SVM), neural network, decision tree, and naïve bayesian are proposed and assessed for this classification. Soil dataset is taken from the real data. Simulation is run by using RapidMiner...
Rapid and vast growth of data volume triggers a need for data management system with good scalability, availability and reliability. NoSQL database comes as a database management system developed to answer the need for such large scale and distributed data management. It is considered more effective and efficient compared to relational database. This database characteristics are very different than...
The growth of vehicles in Yogyakarta Province, Indonesia is not proportional to the growth of roads. This problem causes severe traffic jam in many main roads. Common traffic anomalies detection using surveillance camera requires manpower and costly, while traffic anomalies detection with crowdsourcing mobile applications are mostly owned by private. This research aims to develop a real-time traffic...
In many cases, Coronary artery disease (CAD) results in death. CAD occurs when atherosclerosis blocks the bloodstream to the heart muscle in the coronary arteries. In order to diagnose CAD, there is a gold standard called angiography. However, this method is invasive, risky and expensive. Many researches had been successfully conducted to solve the above problem of angiography by using the data mining...
The popularity of Bus Rapid Transit (BRT) makes Trans Jogja an alternative of a mass public transportation system for urban mobility. However, without supervision on temporal patterns of passenger's behavior in Trans Jogja on supply and demand, it will result in the decreases of the number of BRT users and the increasing number of private vehicle users, so that traffic jams remain difficult to avoid...
Development of technology in educational field brings the easier ways through the variety of facilitation for learning process, sharing files, giving assignment and assessment. Automated Essay Scoring (AES) is one of the development systems for determining a score automatically from text document source to facilitate the correction and scoring by utilizing applications that run on the computer. AES...
Routing will serve to facilitate a number of sensors on the technology of Wireless Sensor Network (WSN) to identify the optimal path and manage energy consumption saving at the time of transmitting data. The optimal path can be identified by using one of the methods from the field of Artificial Intelligent that is path finding method. The method will provide an effective and efficient way to find...
Based on Programme for International Student Assessment survey, Indonesia student performance was on the lower position compared to other participated countries. Nevertheless, the actual reason of someone's performance in studying is hard to predict. Therefore, we need to limit the research's scope for finding more specific influencing factors. In this study, a group of students who have the same...
At recent time, the statistical based language model and neural based language model are still dominating the researches in the field of machine translation. The statistical based machine translation today is the fastest one but it has a weakness in term of accuracy. In contrast, the neural based network has higher accuracy but has a very slow computation process. In this research, a comparison between...
Parkinson is a disease attacking the nervous system and worsens the work of nervous system over time. This disease is incurable, the therapy existing today is only able to help to relieve the symptoms. Hence, an early diagnose is deemed essential to determine an accurate type of therapy. Parkinson disease can be diagnosed by examining the symptoms apparent to the patient. One of the symptoms is the...
Optic disc area is a circular and quite distinct bright region in a digital colour fundus image. This paper provides new method to get an optic disc area automatically. Our method works with some steps. In the first step, the red channel is extracted. Then, the optic disc area is localised using circular average filter to detect the candidate of optic disc point. This point is used to establish the...
Thyroid gland is one of the endocrine glands in the human body which produces thyroid hormone. This gland actively produces two kinds of hormone, namely thyroxine (T4) and triiodothyronine (T3). These hormones aim to produce protein, govern body metabolism, as well as to control body temperature circulation. Either excess or lack of these hormones will disturb those activities. The condition of excessive...
One example of the implementations of digital image processing in biomedical field is to identify the gender of the fetus on the ultrasound image. To identify the gender of the fetus, a fetal must attain the age of at least 5 months of pregnancy. Before the process of identification, there are three steps that must be done, i.e. image preprocessing, image segmentation, and feature extraction (shape...
Forecasting is an activity to predict something that has not happened. In the economic sector, banks have the greatest effect on the economy of a country. Sources of bank funds that contribute to the operational activities or lending is third party funding. The third party funding is consist of savings, giro and deposits. The higher the ratio of third party funding, its mean the better public confidence...
Coronary artery disease (CAD) is a disease that causes many deaths in human. CAD occurs when the atherosclerosis (fatty deposits) blocks blood flow to the heart muscle in the coronary arteries. The gold standard method to diagnose CAD is coronary angiography. However, this method is invasive, risky and costly. Therefore, it is necessary to develop a method for diagnosing the CAD before coronary angiography...
Retinal fundus image provides information of retinal pathologies to diagnose some diseases by computer automatic detection. The quality of the retinal image mostly affects the detection results. In this research, blood vessels contrast measurement algorithm is approached as the first step in no-reference retinal image quality metric. The step includes segmentation of blood vessels. This work was used...
