Abstract

Klasifikasi usia berbasis citra wajah memegang peran krusial dalam berbagai bidang, mulai dari sistem keamanan hingga analisis pasar digital. Dalam studi ini, dikembangkan pendekatan klasifikasi menggunakan Convolutional Neural Network (CNN) dengan arsitektur MobileNetV2 untuk mengkategorikan usia ke dalam empat kelompok: anak, remaja, dewasa, dan lansia. Sebanyak 3.250 citra wajah dari platform Kaggle diproses melalui tahap normalisasi dan augmentasi guna meningkatkan variasi dan mengurangi overfitting. Hasil pengujian menunjukkan bahwa model yang dibangun dengan teknik transfer learning ini mencapai akurasi 84% pada data validasi, dengan performa terbaik di kelas dewasa. Namun demikian, kelas dengan data lebih sedikit menunjukkan kinerja lebih rendah, mengisyaratkan perlunya penanganan khusus untuk ketidakseimbangan data. Temuan ini memperkuat potensi CNN untuk klasifikasi usia, sekaligus menyoroti pentingnya strategi data yang lebih berimbang.

Abstract

College students are vulnerable to depressive symptoms due to academic, social, and personal pressures, which can impact mental health and academic achievement. Early detection is necessary to prevent this condition from developing into a more serious condition, but conventional methods often lack objectivity. With the development of artificial intelligence, machine learning classification algorithms offer a more accurate approach to recognizing patterns of depressive symptoms. This study compared the performance of several classification algorithms, namely Random Forest, K-Nearest Neighbor, Logistic Regression, Decision Tree, Naive Bayes, and Support Vector Machine, using a dataset of depressive symptoms in college students. Evaluation was carried out based on accuracy, precision, recall, and F1-score. The results showed that Logistic Regression achieved the best performance with an accuracy of 95.62%. This suggests that selecting the right algorithm can improve the effectiveness of early depression detection systems in college students and support data-driven mental health efforts.
