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 Chest X-Ray Pneumonia dataset is a binary classification situation where we attempt to predict one of the two possible outcomes.

INTRODUCTION: The dataset contains chest X-ray images selected from retrospective cohorts of pediatric patients of one to five years old from Guangzhou Women and Children’s Medical Center, Guangzhou. The image collection is organized into three folders (train, test, val) and contains subfolders for each image category (Pneumonia/Normal). There are 5,863 X-Ray images with various display resolutions in this collection.

In this Take1 iteration, we will train a simple three-layer CNN model and use the model’s performance as the baseline.

ANALYSIS: In this Take1 iteration, the baseline model’s performance achieved an accuracy score of 100% after 20 epochs using the validation dataset. However, the final model processed the test dataset with an accuracy measurement of only 72.91%.

CONCLUSION: In this iteration, the TensorFlow CNN model appeared to be suitable for modeling this dataset, but we need to experiment with the TensorFlow model to improve its accuracy.
