Abstract

This study presents a novel deep learning approach for early detection of Autism Spectrum Disorder (ASD) using facial image analysis. Leveraging the EfficientNet-B3 model, the research addresses limitations in traditional diagnostic methods by autonomously extracting discriminative facial features associated with ASD. A balanced dataset of 2,940 facial images (1,470 autistic and 1,470 non-autistic children) from Kaggle was pre-processed to 200x200 pixels and evaluated under three dataset-splitting scenarios (80:10:10, 70:15:15, and 60:20:20) to assess generalisability. The model, trained with the Adam optimiser over 10 epochs, achieved optimal performance in the 80:10:10 scenario, with 84.67% precision, 84.35% recall, and 84.32% F1 score. Results demonstrate high confidence (>90% probability) in distinguishing autistic from non-autistic individuals on unseen data. The study underscores the potential of integrating deep learning into clinical decision-support systems for ASD detection, offering a robust, scalable, and efficient solution to improve diagnostic accuracy and reduce reliance on manual methods.

Abstract

The staple food commodity that is crucial to the Indonesian society is rice. Rice often experiences fluctuations in prices. These fluctuations can be predicted using machine learning methods. The aim of this research is to evaluate the accuracy of machine learning algorithms in predicting the premium rice prices in the West Java Province, Indonesia. Two methods used in this study are Linear Regression and Random Forest. The dataset used consists of 6096 records from the Indonesian Food Commodity Management Agency. The evaluation results show that the Random Forest algorithm has an accuracy rate of 98.69%, while the Linear Regression algorithm has an accuracy rate of 95.08%. Based on these results, it is concluded that the Random Forest algorithm is more effective in predicting premium rice prices in the West Java Province compared to the Linear Regression algorithm.

Abstract

Penelitian ini fokus pada penerapan algoritma Naïve Bayes untuk menganalisis sentimen Twitter terhadap Badan Pangan Nasional (BAPANAS). Dalam era digital, media sosial, khususnya Twitter, menjadi saluran utama masyarakat untuk menyampaikan opini terkait instansi pemerintah. Algoritma Naïve Bayes digunakan untuk mengklasifikasikan sentimen menjadi positif atau negatif. Dengan langkah-langkah yang melibatkan crawling data, preprocessing, pelabelan data otomatis menggunakan InSet Lexicon, pembobotan kata dengan TF-IDF, data splitting, dan klasifikasi dengan algoritma Naïve Bayes. Hasil klasifikasi menunjukkan akurasi sebesar 79.7%, dengan presisi 78.6%, recall 74.0%, dan F1 score 76.2%. algoritma Naïve Bayes mengklasifikasikan sebanyak 1.093 data. Dari hasil tersebut, 453 sentimen positif (41.4%) sementara 640 sentimen negatif (58.6%) berdasarkan data testing sebanyak 20%.
