SUMMARY: This project aims to construct a predictive model using a TensorFlow convolutional neural network (CNN) and document the end-to-end steps using a template. The ISIC Challenge 2017 dataset is a binary classification situation where we attempt to predict one of two possible outcomes.
INTRODUCTION: The International Skin Imaging Collaboration (ISIC) is an international effort to improve melanoma diagnosis, sponsored by the International Society for Digital Imaging of the Skin (ISDIS). The ISIC Archive contains the most extensive publicly available collection of quality-controlled dermoscopic images of skin lesions. Since 2016, ISIC has sponsored annual challenges for the computer science community associated with leading computer vision conferences.
For this modeling project, we will make predictions on whether an image represents a melanoma case. In this iteration, we will construct a CNN model based on the InceptionV3 architecture to make predictions.
ANALYSIS: In this iteration, the InceptionV3 model’s performance achieved an accuracy score of 87.80% after ten epochs using the training dataset. The same model processed the validation dataset with an accuracy rate of 82.67%. Finally, the final model processed the test dataset with an accuracy score of 78.50%.
CONCLUSION: In this iteration, the InceptionV3-based CNN model appeared to be suitable for modeling this dataset. We should consider experimenting with TensorFlow for further modeling.
