resnet-50-int8-sparse-v2-tf-0001

Use Case and High-Level Description

This is the Resnet-50 v1 model that is designed to perform image classification. The model has been pretrained on the ImageNet image database and then pruned to 60.4% of sparsity and quantized to INT8 fixed-point precision using so-called Quantization-aware training approach implemented in TensorFlow framework. The sparsity is represented by zeros inside the weights of Convolutional and Fully-conneted layers. For details about the original floating point model, check out the paper.

The model input is a blob that consists of a single image of "1x224x224x3" in BGR order.

The model output for resnet-50-int8-sparse-v2-tf-0001 is the usual object classifier output for the 1000 different classifications matching those in the ImageNet database.
