 # 🪨 Core Sample Main Fraction Classifier
 
-This multi-label classification model was fine-tuned for automated visual analysis of soil core samples, and trained / validated / tested on the `grano1/core_sample_image_data` dataset available via the HuggingFace eco-system. The model aims to predict one of the following four class labels from cropped core sample images (300x300 pixels):
