Abstract

Alzheimer's disease is the most common cause of dementia. Dementia refers to brain symptoms such as memory loss, difficulty thinking and problem solving and even speaking. This stage of development of neuropsychiatric symptoms is usually examined using magnetic resonance images (MRI) of the brain. The detection of Alzheimer's disease from data such as MRI using machine learning has been the subject of research in recent years. This technology has facilitated the work of medical experts and accelerated the medical process. In this study we target the classification of Alzheimer's disease images using convolutional neural network (CNN) and transfer learning (VGG16 and VGG19). The objective of this study is to classify Alzheimer's disease images into four classes that are recognized by medical experts and the results of this study are several evaluation metrics. Through experiments conducted on the dataset, this research has proven that the algorithm used is able to classify MRI of Alzheimer's disease into four classes known to medical experts. The accuracy of the first CNN model is 75.01%, the second VGG16 model is 80.10% and the third VGG19 model is 80.28%.

Abstract

Indonesia merupakan salah satu negara yang bergerak di sektor industri, hal tersebut memungkinkan lingkungan hidup termasuk kualitas udara. Polusi udara yang dikeluarkan dari cerobong asap kawasan industri tidak dapat dilakukan dengan baik maka akan berdampak buruk pada kesehatan manusia. Pemantauan kualitas udara yang digunakan saat ini yaitu hanya terdapat satu alat saja yang digunakan untuk melakukan monitoring terhadap suatu cakupan lokasi tertentu, sehingga akan kurang sesuai untuk menggambarkan kondisi kualitas udara yang ada pada suatu cakupan lokasi tersebut. Sementara untuk instalasi lebih dari satu alat akan membutuhkan biaya yang besar. Pada penelitian ini diaplikasikan konsep wireless sensor network (WSN) untuk pemantauan kualitas udara dengan pemasangan node sensor lebih dari satu perangkat pada lokasi tertentu dan terdapat satu sink yang bertindak untuk mengumpulkan data dari node sensor dan mengirimkannya ke server. Data kualitas udara yang didapatkan oleh node sensor kemudian diklasifikasikan menggunakan metode klasifikasi pada data mining yaitu k-nearest neighbor (K-NN). Sebelum dilakukan klasifikasi menggunakan K-NN, dilakukan normalisasi data untuk penyamaan skala datanya, didapatkan normalisasi decimal scaling yang memiliki performansi yang baik untuk data kualitas udara. Nilai k yang digunakan untuk klasifikasi K-NN yaitu 5. Didapatkan tingkat akurasi yang dihasilkan oleh sistem sebesar 94,28%, presisi sebesar 85,16% dan recall sebesar 93,35%.

Abstract

Recently, Indonesia, as a country where the majority of the population chooses rice as the primary food source, gets a decline in the rice consumption patterns, which resulted in reduced demand for rice that should have been stable. The decrease of rice purchasing power impacts several rice suppliers, commonly referred to as rice agents, to buy rice from rice production companies. Therefore, prediction of rice stock is essential to do. This paper aims to apply the backpropagation neural network method to forecast the amount of rice demand. The data used in the study is time-series data in the form of the number of requests for rice as much as 609 data from two types of rice. The modeling scenario in this study applies one to five hidden layers with a different number of hidden neurons in each experiment. The elastic net regularization method was applied after the data denormalization process to improve the quality of the resulting model. Based on the experiments, obtained the best model on architecture 7-50-200-300-250-300-1 with MSE = 0.001278, RMSE = 0.301950 in the training process and MSE results = 0.002391, RMSE = 0.204972 in the testing process.

Abstract

Pneumonia is a significant global health concern, particularly affecting young children and the elderly. It is a lung infection caused by bacteria, viruses, fungi, or parasites, leading to the alveoli filling with pus or fluid. This study addresses the challenge of accurately diagnosing pneumonia using chest X-ray images, a process traditionally dependent on the expertise of radiologists. The reliance on radiologists results in lengthy diagnosis times and high costs, particularly in regions with a shortage of medical professionals. This research presents a deep-learning approach to automate the classification of pneumonia using the ResNet50v2 model, which has been pre-trained on the ImageNet dataset. The dataset used in this study, obtained from the Guangzhou Women and Children’s Medical Center, comprises 5,856 images, with 1,583 normal and 4,273 pneumonia cases. The images were preprocessed and augmented to enhance the model's robustness. The proposed model achieved an accuracy of 94%, demonstrating its potential in clinical settings to assist in the rapid and reliable diagnosis of pneumonia. This study contributes to the growing body of research in medical image analysis by employing a pre-trained ResNet50v2 model. It highlights the importance of leveraging advanced machine-learning techniques to improve diagnostic accuracy and efficiency.
