Abstract

This article presents a computer vision approach for the automated classification of minerals from microscopic images, a task of significant relevance in geological and mining applications. The proposed method employs the ResNet50 architecture within a Transfer Learning framework and is optimized through a rigorous hyperparameter search. The final model, trained using a batch size of 8 and an L2 regularization factor of 1.0×10-⁵, achieved a validation loss of 0.0447 and a validation accuracy of 98.35% across ten mineral classes. The results indicate a superior generalization capability compared to baseline models, establishing the proposed classifier as a reliable tool for laboratory sample analysis.
