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 Fruits and Vegetables Image Recognition is a multi-class classification situation where we attempt to predict one of several (more than two) possible outcomes.
INTRODUCTION: The dataset owner collected over 4,300 pieces of fruit and vegetable images and created a dataset that includes 36 classes. The idea was to build an application that recognizes the food items from the captured photo and provides different recipes that can be made using the food items.
ANALYSIS: The NASNetMobile model’s performance achieved an accuracy score of 89.74% after 40 epochs using a separate validation dataset. After tuning the learning rate, we improved the accuracy rate to 95.16% using the same validation dataset. When we applied the model to the test dataset, the model achieved an accuracy score of 91.92%.
CONCLUSION: In this iteration, the TensorFlow NASNetMobile CNN model appeared suitable for modeling this dataset.
