Abstract

This study presents a comprehensive evaluation of AdaBoost and Random Forest Classifier algorithms in the classification of eye diseases, focusing on a challenging scenario involving an imbalanced dataset. Eye diseases, particularly Cataract, Diabetic Retinopathy, Glaucoma, and Normal eye conditions, pose significant diagnostic challenges, and the advent of machine learning offers promising avenues for enhancing diagnostic accuracy. Our research utilizes a dataset preprocessed with Canny edge detection for image segmentation and Hu Moments for feature extraction, providing a robust foundation for the comparative analysis. The performance of the algorithms is assessed using a 5-fold cross-validation approach, with accuracy, precision, recall, and F1-score as the key metrics. The results indicate that the Random Forest Classifier outperforms AdaBoost across these metrics, albeit with moderate overall performance. This finding underscores the potential and limitations of using advanced machine learning techniques for medical image analysis, particularly in the context of imbalanced datasets. The study contributes to the field by providing insights into the effectiveness of different machine learning algorithms in handling the complexities of medical image classification. For future research, it recommends exploring a diverse range of image processing techniques, delving into other sophisticated machine learning models, and extending the study to encompass a wider array of eye diseases. These findings have practical implications in guiding the selection of machine learning tools for medical diagnostics and highlight the need for continuous improvement in automated systems for enhanced patient care.

Abstract

Pengelolaan kinerja pegawai adalah aspek kunci dalam menjaga produktivitas dan kualitas kerja dalam institusi, dalam hal ini institusi pendidikan seperti UTDI. Dalam lingkungan kerja yang sangat kompetitif dan dinamis, penting bagi institusi untuk mengidentifikasi, mengakui, dan memberikan penghargaan kepada pegawai yang telah memberikan kontribusi yang luar biasa terhadap pencapaian tujuan. Untuk mencapai hal ini, seringkali menggunakan metode penilaian kinerja pegawai. Metode menentukan pemberian penghargaan kepada pegawai yang memiliki kinerja luar biasa, digunakan pendekatan gabungan yang terdiri dari metode Simple Additive Weighting (SAW) dan Analytic Hierarchy Process (AHP). Metode SAW digunakan untuk menghitung skor kinerja pegawai dengan memberikan bobot pada kriteria penilaian. Bobot ini didasarkan pada perbandingan pentingnya masing-masing kriteria. Penilaian kinerja menggunakan metode AHP dan SAW memberikan hasil yang sistematis dan dapat dipertanggungjawabkan. Visualisasi yang disajikan membantu memperkuat pemahaman terhadap hubungan antar kriteria dan bagaimana kinerja pegawai dinilai secara keseluruhan. Metode ini sangat bermanfaat dalam konteks penilaian multi-kriteria di berbagai organisasi.
