This project deals with performance evaluation of Multilayer Perceptron (MLP) in classifying malignant, benign melanoma and normal mole. Skin tumor is a condition of uncontrolled growth of cells in the skin which may be cancerous. Melanoma is one of the common types of skin cancer. The aim is to develop a standalone application for the diagnosis of skin tumors.
Dermoscopic images are obtained from the PH2 database, an authorized and standardized database accepted by many dermatologists all over the world. The images were obtained with the help of the dermoscopy system with a magnification power of 20X. The database contains more than 5000 images of skin tumors which include abnormal naevi, melanomas, common naevi, and benign tumors. We used 1500 images that were collected across three different types of skin tumors including atypical naevus (benign tumors), malignant melanoma, and common naevus (moles).
We extracted 15 different features including morphological, diagnostic clinical, statistical, and Grey Level Co-occurrence Matrix (GLCM). A complete description of the features and the feature selection processes are available in the published paper made available in this repository.An approach with advanced Multilayer Perceptron is attempted with the dataset, where the effect of hyperparameter optimization has been thoroughly discussed.

Feel free to run the codes from the attached Jupyter Notebook. The codes can be used with your own custom datasets. All that you need is a CSV file containing the features and class labels. We believe the code would be of good value for the research community and request to kindly cite our study: T. R. Thamizhvani, Suganthi Lakshmanan & R. Sivaramakrishnan (2018).
