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 Alzheimer’s MRI Images 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. The inspiration behind sharing this dataset is to make highly accurate models for predicting the stages of Alzheimer’s disease.
ANALYSIS: The VGG19 model’s performance achieved an accuracy score of 99.43% after five epochs using the training dataset. When we applied the model to the validation dataset, the model achieved an accuracy score of 72.87%.
CONCLUSION: In this iteration, the TensorFlow VGG19 CNN model appeared suitable for modeling this dataset.
Dataset ML Model: Multi-Class classification with numerical features
Dataset Used: Alzheimer’s Dataset (4 Class of Images)
