Style-Based Recalibration Module

The official PyTorch implementation of "SRM : A Style-based Recalibration Module for Convolutional Neural Networks" for ImageNet. SRM is a lightweight architectural unit that dynamically recalibrates feature responses based on style importance.

Overview of Results
