Classifying Chest X-ray with Spark Deep Learning

1. Introduction

5. Project Infrastructure

To apply image classification and object detection on large scale of images, several libraries have been introduced to integrate deep learning frameworks such as Cognitive Toolkit (CNTK), TensorFlow, BigDL for purpose into Apache Spark. Among these Deep Learning Pipeline has become one popular choice.

Deep Learning Pipelines provides easy-to-use high-level APIs for scalable deep learning in Python with Apache Spark. It is an open source library created by Databricks, and supporting ensorFlow and TensorFlow-backed Keras workflows. In particular, it can be used with pre-trained models as well as transfer learning.
