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 Belgium Traffic Sign dataset is a multi-class classification situation where we attempt to predict one of several (more than two) possible outcomes.
INTRODUCTION: This dataset includes 101 food categories, totaling 101,000 images. The research team provided 250 manually reviewed test images and 750 training images for each food type. All images were rescaled to have a maximum side length of 512 pixels.
ANALYSIS: The DenseNet201 model’s performance achieved an accuracy score of 85.22% after ten epochs using the training dataset. When we applied the model to the validation dataset, the model achieved an accuracy score of 77.94%.
CONCLUSION: In this iteration, the TensorFlow DenseNet201 CNN model appeared suitable for modeling this dataset.
