octave-se-resnet-50-0.125

Use Case and High-Level Description

The octave-se-resnet-50-0.125 model is a modification of se-resnet-50 from this paper with octave convolutions from Drop an Octave: Reducing Spatial Redundancy in Convolutional Neural Networks with Octave Convolution with alpha=0.125. As origin, it's designed to perform image classification. For details about family of octave convolution models, check out the repository.

The model input is a blob that consists of a single image of 1, 3, 224, 224 in RGB order. The RGB mean values need to be subtracted as follows: [124, 117, 104] before passing the image blob into the network. In addition, values must be divided by 0.0167.

The model output for octave-se-resnet-50-0.125 is the typical object classifier output for the 1000 different classifications matching those in the ImageNet database.
