How to Explain Deep Learning Using Chaos and Complexity
- pizza 10y agohttp://nuit-blanche.blogspot.com/2017/01/understanding-deep-learning-requires.html http://nuit-blanche.blogspot.com/2017/01/understanding-deep-... Here is an interesting paper that pinpoints the influence of regularization on learning with Neural networks. From the paper: > Our central finding can be summarized as: Deep neural networks easily fit random labels. and later: > While simple to state, this observation has profound implications from a statistical learning perspective: > 1. The effective capacity of neural networks is large enough for a brute-force memorization of the entire data set. > 2. Even optimization on random labels remains easy. In fact, training time increases only by a small constant factor compared with training on the true labels. > 3. Randomizing labels is solely a data transformation, leaving all other properties of the learning problem unchanged. I subscribe to Schmidhuber's notion that algorithms that rely upon randomness to select parameters have a very illusory "simplicity" that relies upon externalizing the complexity of the PRNG. http://people.idsia.ch/~juergen/newai/ http://people.idsia.ch/~juergen/newai/
