OctaveConv

A MXNet Implementation for Drop an Octave

This repository contains a MXNet implementation of the paper Drop an Octave: Reducing Spatial Redundancy in Convolutional Neural Networks with Octave Convolution.

Model	Top1
ResNet-v1-50	76.05
OctResNet-v1-50	77.47
OctResNet-v1-50-cosine	78.04

OctResNet-v1-50-cosine model used alpha = 0.25 in the table 2 of the paper.

To Do List

• support mobilenet v1/v2
