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 American Sign Language Alphabet Dataset is a multi-class classification situation where we attempt to predict one of several (more than two) possible outcomes.
INTRODUCTION: The dataset contains over 22,000 images of alphabets from American Sign Language, separated into 29 folders that represent the various classes. The research team collected these images to investigate the possibilities of reducing the communication gap between sign-language users and non-Sign language users.
ANALYSIS: The NASNetMobile model’s performance achieved an accuracy score of 99.26% after ten epochs using the training dataset. When we applied the model to the validation dataset, the model achieved an accuracy score of 86.92%.
CONCLUSION: In this iteration, the TensorFlow NASNetMobile CNN model appeared suitable for modeling this dataset.
