Image Classifier – ResNet50

Overview

This model recognizes the 1000 different classes of objects in the ImageNet 2012 Large Scale Visual Recognition Challenge. The model consists of a deep convolutional net using the ResNet-50 architecture that was trained on the ImageNet-2012 data set. The input to the model is a 224×224 image, and the output is a list of estimated class probilities. The model is based on the Keras built-in model for ResNet-50.
