Fatty liver disease (FLD) is a prevalent medical condition characterized by the accumulation of excess fat in the liver, leading to liver dysfunction and potentially severe complications. Accurate classification of FLD subtypes is crucial for effective diagnosis and treatment planning. In this study, we propose a classification framework based on supervised learning and optimization algorithms to improve the accuracy and efficiency of FLD subtype identification. We utilize a dataset comprising various clinical features, imaging data, and histopathological findings to train and evaluate our classification model. The supervised learning component employs existing machine learning algorithms to learn the complex relationships between input features and FLD subtypes. Additionally, we integrate optimization algorithms, to enhance the model's performance by optimizing hyperparameters and feature selection.
