Melanoma can affect anyone and early detection is a crucial factor affecting survival rates. Machine learning models could assist trained healthcare professionals in screening for skin cancer. The Human Against Machine 10000 (HAM10000) dataset contains images of 7,470 distinct skin lesions, each belonging to one of seven mutually-exclusive classes of skin lesion, including melanoma, as well as other cancerous types and benign types such as nevi (moles). Our goal was to train a convolutional neural network (CNN) to accurately classify images of skin lesions using the HAM10000 dataset. The project includes a Streamlit app to test users’ classification ability against our fine-tuned models.
