This repository contains convolutional neural network (CNN) models trained on ImageNet by Marcel Simon at the Computer Vision Group Jena (CVGJ) using the Caffe framework as published in the accompanying technical report. Each model is in a separate subfolder and contains everything needed to reproduce the results. This repository focuses currently contains the batch-normalization-variants of AlexNet and VGG19 as well as the training code for Residual Networks (Resnet).
No mean subtraction is required for the pre-trained models! We have a batch-normalization layer which basically does the same.
The pre-trained models can be obtained by the download link written in model_download_link.txt.
If you want to train on your own dataset, simply execute caffe train --solver train.solver --gpu 0 2> train.log to start the training and write the output to the log file train.log. Please note, that we pre-scaled all images of the dataset such that the smaller side has a length of 256 pixels while keeping the aspect ratio. You can use convert input.jpg -resize 256x256^ output.jpg to convert the images using the command line.
To evaluate the final model, execute caffe train --solver test.solver --gpu 0 2> test.log.
Single-crop error rates on the validation set of the ILSVRC 2012--16 classification task.
| Model | Top-1 error (vs. original) | Top-5 error (vs. original) |
|---|---|---|
| AlexNet_cvgj | 39.9% (vs. 42.6%) | 18.1% (vs. 19.6%) |
| VGG19_cvgj | 26.9% (vs. 28.7%) | 8.8% (vs. 9.9%) |
| ResNet10_cvgj | 36.1% | 14.8% |
| ResNet50_cvgj | 24.6% (vs. 24.7%) | 7.6% (vs. 7.8%) |
