Learning Vector Quantization (LVQ) is a type of Artificial Neural Network with a supervised learning process based on competitive learning. Despite the absence of assumptions in LVQ is an advantage, it can be a problem when the predictor variables have big different ranges.This problems can be overcome by equalizing the range of all variables by data transformation so that all variables have relatively same effect. Heart Disease UCI dataset which used in this study is transformed by several transformation methods, such as minmax, decimal scaling, z-score, mean-MAD, sigmoid, and softmax. The result show that the six transformed data can provide better LVQ classification accuracy than the raw data which has 75.99% for training performance accuracy. LVQ classification accuracy with data transformation of minmax, decimal scaling, z-score, mean-MAD, sigmoid, and softmax are 89.16%, 88.22%, 89.7%, 90.1%, 88.17% and 92.18%. Based on the One-way ANOVA test and DMRT post hoc test  known that there are significant differences between the results of the classification with data transformations and raw data in 0,05 significant level of α. It is also known that the best data transformation methods are softmax for training and sigmoid for testing. Keywords: heart disease, neural network, learning vector quantization, classification, data transformation

Dengue Hemorrhagic Fever is a disease that is carried and transmitted through the mosquito Aedes aegypti and Aedes albopictus which is commonly found in tropical and subtropical regions such as in Indonesia to Northern Australia. in 2013 there are 2.35 million reported cases, which is 37,687 case is heavy cases of DHF. DHF’s symthoms have a similarity with typhoid fever, it often occur wrong handling. Therefore we need a system that is able to diagnose the disease suffered by patients, so that they can recognize whether the patient has DHF or Typhoid. The system will be built using Neural Network Learning Vector Quantization (LVQ) based on the best training results. This research is to diagnose Dengue Hemorrhagic Fever using LVQ with input parameters are hemoglobin, leukocytes, platelets, and heritrocytes. Based on result, the best accuracy is 97,14% with Mean Square Error (MSE) is 0.028571 with 84 train data and 36 test data. Conclution from the research is LVQ method can diagnose DHF Keywords: Dengue Hemorrhagic Fever; Learning Vector Quantization; classification; Neural Network;

Artificial Neural Network (ANN) is an information processing system that has certain performance characteristics that are artificial representatives based on human neural networks. ANN method has been widely applied to help human performance, one of which is health. In this research, ANN will be used to diagnose cataracts, especially Congenital Cataracts, Juvenile Cataracts, Senile Cataracts and Traumatic Cataracts based on the symptoms of the disease. The ANN method used is the Learning Vector Quantization (LVQ) method. The data used in this research were 146 data taken from the medical record data of RSUD Dr. M. Haulussy, Ambon. The data consists of 109 data as training data and 37 data as testing data. By using learning rate (α) = 0.1, decrease in learning rate (dec α) = 0.0001 and maximum epoch (max epoch) = 5, the accuracy rate obtained is 100%.

Abstrak-Pada saat ini, Jaringan Syaraf Tiruan (JST) telah banyak menjadi objek penelitian yang menarik, karena penerapannya sangat potensial dalam berbagai bidang sains, salah satu penerapannya didalam memprediksi penyakit. Penelitian ini bertujuan untuk mencoba menerapkan metode Learning vector Quantization (LVQ) dalam memprediksi jenis cacing Nematoda usus yang menginfeksi siswa dari nilai akurasi yang dihasilkan, karena beberapa penelitian menunjukkan bahwa anak usia sekolah dasar merupakan golongan yang sering terkena infeksi cacing usus. Dari hasil pelatihan dan pengujian menggunakan metode Learning Vector Quantization (LVQ) diketahui bahwa tingkat akurasi sesuai dengan hasil sebenarnya dan nilainya konstan, proses cepat hanya membutuhkan waktu paling lama 3 menit dan memberikan hasil yang optimal yaitu tingkat akurasi data latih sebesar 78,6885%, serta 80% untuk data uji. Hal ini menunjukkan bahwa jaringan yang terbentuk sudah cukup baik, akurat dan cepat dalam melakukan pembelajaran terhadap data input yang diberikan dalam memprediksi jenis cacing Nematoda Usus yang menginfeksi siswa. Kata kunci : Cacing Nematoda Usus, Jaringan Syaraf Tiruan, Learning Vector Quantization Abstract- At this time, an Artificial Neural Network (ANN) has been an interesting objects of research, because of application has potential in various fields of science, one application was used to predict diseases. This study aims to try to implement methods Learning vector quantization (LVQ) in predicting the type of Nematode worms that infect the intestines of students from the resulting accuracy value, because some studies show that children of primary school age are often exposed to a class of intestinal worm infections. From the results of the training and testing using methods Learning Vector Quantization (LVQ) note that the level of accuracy in accordance with the actual results and the value of the constant, quick process only takes a maximum of 3 minutes and provide optimal results is the level of training data accuracy of 78.6885%, and 80% for the test data.
