A new link to an old model could crack the mystery of deep learning
A lot of effort went into these efforts to understand neural networks in terms or kernels or SVMs. To the best of my knowledge, these efforts have not inspired useful new architectures, nor have they made useful experimental predictions on real neural nets, nor have they had any significant impact on important machine learning benchmarks.I think some researchers are refusing to accept the idea that machine learning is very much an experimental science today, and the (very cool) mathematics of kernels, SVMs, empirical risk minimization, bayesian statistics, etc. are simply no longer useful in the large scale regime.My prediction is that there will be a useful "deep learning theory" in the future, but it will look a lot more like physics (such as Kaplan's scaling laws) than early 21st century machine learning mathematics/statistics.
