# Collective Residual Networks

This repository contains the code and trained models of "Sharing Residual Units Through Collective Tensor Factorization in Deep Neural Networks".

## Implementation

### Augmentation

| Method         |  Settings  |

| :------------- | :--------: |

| Random Mirror  |    True    |

| Random Crop    |  8% - 100% |

| Aspect Ratio   |  3/4 - 4/3 |

| Random HSL     | [20,40,50] |

> Note: 

> We did not use PCA Lighting and any other advanced augmentation methods.

### Normalization

The augmented input images are substrated by mean RGB = [ 124, 117, 104 ], and then multiplied by 0.0167.

## Results

### ImageNet-1k

**Single crop validation error (center 224x224 crop from resized image with shorter side=256):**

Model|Setting|Model Size|Top-1

:-----|------:|---------:|:---:

CRU-Net-56 @x14|32x4d|98MB|21.9%

CRU-Net-56 @x14|136x1d|98MB|21.7%

CRU-Net-116 @x28x14|32x4d|168MB|20.6%

CRU-Net-116, wider @x28x14|64x4d|318MB|20.3%

We also trained a tiny CRU-Net-56 with less than half the size of ResNet-50.
