Abstract

Electrocardiogram (ECG) can be used to recognize abnormal heart beats or arrhythmia. Automatic arrhythmia recognition can be achieved through the use of machine learning techniques. However, ECG generates raw numerical data with large amount of features that can reduce the quality of automatic recognition. Genetic algorithm (GA) can be utilized to perform a feature selection, reducing the amount of features. Data with reduced features then will be used to train a support vector machine (SVM) classifier. ECG data from the Massachusetts Institute of Technology-Beth Israel Hospital (MIT-BIH) arrhythmia database is used as training and testing data. Each data is a six-second ECG recording, and is classified into normal heartbeat and 3 different kind of arrhythmias. Result shows that GA-SVM yielded average accuracy of 82.5% with 120 training data and 20 test data, and reduced the amount of feature from 2160 original features to an average of 406 reduced features.

Abstract

Fever is a rise in body temperature is higher than usual. Fever is not a disease, but the initial symptoms of a person affected by the disease. There are many diseases caused by fever, such as Typhoid Fever and Dengue Haemorragic Fever. Both diseases when observed clinically will be difficult to distinguish them. Because the two diseases almost have the same symptoms and if there is an error in diagnosing it will cause a fatal thing in the patient. Typhoid Fever disease is a fever caused by Salmonella Typhi bacteria that spread throughout the body and Haemorragic Fever Dengue fever caused by Aedes Aegypti mosquito bites. To overcome this, then made a classification system of disease diagnosis Typhoid Fever and Dengue Haemorragic Fever based on symptoms possessed by patients by applying desicion tree algorithm C4.5. Accuracy obtained by Typhoid Fever (TF) and Dengue Haemorhagic Fever (DHF) classification system by k-folds cross validation test showed the highest accuracy value on 5-fold cross validation with accuracy of 91,875% using 32 data test and Training data of 128 data. The results of the 4th test on 5-fold cross validation test resulted in the highest accuracy of 97%. While the analysis by conducting 16-fold cross validation test of the test data of 10 data and training data of 150 data, obtained the result of the test value of 100% on the 2nd, 3rd, 4th, 6th, The 9th, the 11th, the 12th and the 16th. Although the 100% accuracy value obtained in this test is numerous, the average accuracy of the 16-fold cross validation test is still below the average score of accuracy obtained by testing 5-fold cross validation.

Abstract

Various attempts at securing personal information have been done in both traditional and biometric ways. And among the various ways to protect information, signatures are the most widely used in identifying and verifying personal information. Therefore, efforts should be made to be able to recognize whether the signature is genuine or false by performing detection and verification. In performing the detection process used steps consisting of preprocessing, geometric extraction features, and classification with the modified-K approach method of Nearest Neighbors as a way of verifying signatures. The preprocessing process consists of filtering, binarization, thinning, cropping, and resizing. Then extraction process geometric cirri. Before performing the extraction, zoning on the image with 3 different techniques are vertical, horizontal, and zoning 4 parts. After that is done classification for signature verification process. The result is by testing the zoning technique to determine the value of FRR and FAR of each technique. The smallest FRR value obtained is 54% and the smallest FAR value is 7%. The value is obtained by applying the vertical zoning technique. This shows that the system has a good ability in performing the verification process against fake signatures. While in the process of verification of the original signature the ability of the system is still low. So in accordance with the results obtained, to improve the ability of the system can be improved on the process of preprocessing the image.

Abstract

Inflation is a monetary phenomenon in a country where ups and downs result in economic turmoil. Bank Central Indonesia sets the inflation target for the next time with the Inflation Targeting Framework (ITF) as a reference for monetary policy. If the actual inflation does not match the inflation target, then the policy is needed to return inflation to such an inflation target. Based on the inflation rate problem, this research is expected to provide inflation target for the future through inflation rate forecasting using combined Multi-Factors High Order Fuzzy Time Series method with Fuzzy C-Means. Fuzzy C-Means is used to determine the cluster center to be used as a basis for the development of intervals, the use of Fuzzy C-Means is expected to reflect the real data so that the results of forecasting is better. In forecasting used 4-factor data that includes time series data rate inflation and 3 factors that affect. The results of the combined implementation of Multi-Factors High Order Fuzzy Time Series method with Fuzzy C-Means tested the error of forecasting using Mean Absolute Percentage Error (MAPE). Based on the test the error value is 11.33676%, which indicates that the combined method of Multi-Factor High Order Fuzzy Time Series with Fuzzy C-Means is included in the good category used in forecasting the inflation rate in Indonesia because it has an accuracy value below 20%.
