That's exactly what I was going to post, but you beat me. I found surprising that they claim competitive performance over neural networks just using a CPU. The advantage I think neural networks have over all other methods is how efficiently they run on GPUs. I would love to see other methods take advantage of modern hardware or parallelism and see if they can catch up with neural networks on image classification.
