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 Augmented Alzheimer’s MRI dataset is a multi-class classification situation where we attempt to predict one of several (more than two) possible outcomes.

INTRODUCTION: The dataset contains four different classes of Alzheimer’s disease MRI images. The research team collected these images from various websites and manually verified each label. Furthermore, the research team produced many more augmented MRI images and added them to the training dataset to improve the model. The intent is to use the original image dataset for testing the new model’s capabilities.

ANALYSIS: The ResNet50V2 model’s performance achieved an accuracy score of 98.95% after five epochs using the training dataset. When we applied the model to the validation dataset, the model achieved an accuracy score of 97.30%.

CONCLUSION: In this iteration, the TensorFlow ResNet50V2 CNN model appeared suitable for modeling this dataset.
