Abstract

Emosi merupakan kondisi psikofisiologis seseorang dengan faktor internal dan/atau lingkungan. Pengenalan akurat dari emosi wajah melalui sistem pengenalan visi komputer akan kondusif untuk kelancaran kemajuan interaksi manusia-komputer. Selain itu, karena dinamika dan heterogenitas layanan seluler, dibutuhkan sistem pengenalan emosi yang dapat memproses data secara akurat dengan waktu komputasi yang minimal. Kami mengusulkan penggunaan MobileNetV3 dengan penjadwalan learning rate serta penambahan attention module guna mendapatkan model dengan performa akurasi baik namun efisien dalam penggunaan sumber daya, seperti ukuran model, jumlah parameter yang rendah, dan waktu komputasi yang cepat, sehingga cocok diterapkan pada perangkat mobile. Adanya SE (Squeeze and Excitation) dan fungsi h-swish memungkinkan MobileNetV3 mempertahankan akurasi sekaligus mengurangi jumlah parameter secara signifikan. Adapun fitur localization dan sampling grid pada spatial transformer membantu model untuk fokus ke bagian yang diperlukan guna meningkatkan akurasi. Pada penelitian ini dibuktikan bahwa metode yang digunakan memberikan hasil yang baik dengan akurasi validasi sebesar 69.89% pada dataset FER2013 dan 84.10% pada FER2013+ dengan ukuran model sebesar 16.36 MB dan parameter 4,235,112 menunjukkan efisiensi memori dan kecepatan inferensi yang signifikan dibandingkan model lain seperti ResNet50 sehingga dapat dinyatakan model memiliki performa akurasi yang baik dengan efisiensi memori dan komputasi yang cukup baik.

Abstract

Climate change is a significant challenge for both humans and the environment, with its impacts increasingly felt across various regions of the world. The most evident consequence is the alteration of extreme weather patterns, which often lead to destructive and life-threatening natural disasters. Among these, extreme rainfall was the most damaging factor, frequently triggering floods. However, the increasing occurrence of related events outlined the urgent need for developing more accurate rainfall forecasting systems as a strategic measure for disaster risk reduction. This research adopted daily rainfall data from Samarinda City, collected between 2004 and 2012, to conduct prediction using both machine and deep learning methods. The implementation of machine learning methods, such as Support Vector Regression (SVR), enabled the model to learn from historical data and uncover complex patterns, resulting in accurate forecasts and improved adaptability to climate variability. Meanwhile, deep learning models, including Recurrent Neural Networks (RNN) and Long Short-Term Memory (LSTM), enhanced prediction performance by capturing more intricate and abstract data relationships. Performance evaluations conducted using Mean Absolute Error (MAE) and Mean Squared Error (MSE) showed that deep learning outperformed machine learning in accuracy. The LSTM model achieved the best performance, with loss values of 0.0482 and 0.0527 for MSE and MAE, respectively. The advantage of deep learning lies in its ability to build more complex models for handling non-linear problems and to learn data representations at various levels of abstraction, which has led to more accurate results. Furthermore, LSTM surpassed RNN by effectively overcoming the vanishing gradient issue, allowing for more stable and efficient training that led to superior predictive performance.

Abstract

This study investigates a hybrid machine learning framework combining EfficientNet-B3 feature extraction with classical classifiers for lettuce disease classification under conditions of extreme class imbalance. The system utilizes EfficientNet-B3 to extract high-dimensional feature embeddings from 2,337 images, which are subsequently classified using support vector machine (SVM), random forest (RF), and k-nearest neighbors (KNN). Although the proposed SVM-based model achieves a high overall accuracy of 94.01%, experimental results reveal a substantial performance discrepancy compared to the macro F1-score of 37.94%. This critical gap indicates that while the model successfully identifies the majority classes, it fails to recognize rare disease categories with limited samples. Theoretical analysis suggests that while SVM handles high-dimensional feature spaces more effectively than RF and KNN, the deep features extracted are biased toward majority class characteristics. These findings highlight the severe limitations of accuracy-centric evaluation in agricultural diagnostics and demonstrate that deep feature extraction alone is insufficient to guarantee robust detection for minority pathologies. The study concludes that relying on aggregate accuracy can mask diagnostic failures, emphasizing the urgent need for per-class performance analysis and data-level mitigation strategies in future research.

Abstract

Malang Regency has many different types of land and coffee varieties in each sub-district. It spans from highland Arabica coffee in Poncokusumo, grown at 900 to 1,400 meters above sea level, to lowland Robusta coffee in Gedangan, grown at less than 300 meters above sea level. These differences make the green coffee beans have very different sensory profiles. However, the way people decide how to roast the beans is still mostly based on experience and cannot be easily shared. In this study, a seven-stage Soft Systems Methodology (SSM) was used to create a conceptual Decision Support System (DSS) framework that can recommend coffee roasting parameters. Data was collected through field observations and interviews with experienced roasters, farmers/farmer cooperative leaders, and staff from the Malang Regency Agriculture Office in all ten sub-districts. The SSM process resulted in several outputs, including a Rich Picture that shows six groups of actors and three main social and technical problems, a root definition using CATWOE that explains how unclassified green beans can be turned into roasting profile recommendations for each origin, a conceptual model with ten activities, and a gap analysis that found the biggest problems are the lack of formal roasting knowledge and the absence of a system to deliver recommendations to users. The proposed framework has a seven-layer DSS design that uses computer vision with edge computing to classify green bean quality and includes a knowledge base for each sub-district. It is made to work offline in rural areas with limited resources. The framework was tested using the Efficacy, Efficiency, Effectiveness, and Elegance (4Es) criteria. The results showed that SSM can be used as a structured and repeatable way to design agroindustrial DSS in tropical coffee-producing regions with many different stakeholders and limited infrastructure.

The technology uses unique patterns in iris for secure and reliable identification purposes but certain challenges are encountered in ensuring consistent image segmentation. Therefore, this research focuses on developing iris image segmentation using deep learning as an important step in biometric identification process. Image segmentation aims to separate iris region from other parts of the eye, such as the pupil, sclera, and eyelids. However, the process requires a more sophisticated method to overcome image variations. This research implements popular deep learning architectures, DeepLabV3 and U-Net, for the segmentation. Subsequently, the performance of the models was evaluated based on the IoU Score, accuracy, precision, recall, and F1-score metrics. The results showed that DeepLabV3 provided the best performance with an IoU Score of 0.918, accuracy of 0.993, precision of 0.962, recall of 0.952, and F1-score of 0.957. The advantage of the model was associated with the ability to effectively extract complex features and capture information context at different scales. The observation was an indication of the significant potential possessed by deep learning applications in iris image segmentation for biometric systems. Moreover, the optimal performance achieved by DeepLabV3 showed the possibility of depending on the technology to improve the accuracy and efficiency of biometric identification process, opening up broad opportunities for further development in iris-based security applications.
