## Description

clara_xray_classification_chest_no_amp is a pre-trained densenet121 model for disease pattern detection in chest x-rays.

## Model Overview

The model is trained using a densenet121 model [1] for disease pattern detection in chest x-rays [2].

### Data

This model is trained using PLCO training data and evaluated on the PLCO validation data.

You can apply for access to the dataset at: https://biometry.nci.nih.gov/cdas/learn/plco/images/
