Yes, we are aware of the formal complaint surrounding Extreme Learning Machines. Essentially the same algorithm was published in a *1992 *paper (http://homepage.tudelft.nl/a9p19/papers/icpr_92_random.pdf), *neural networks with random weights* - more than 10 years before ELMs came to light. W

It's a little bit off-topic, and I am really not that much into the literature to be a judge of that, but just a few days ago there was formal letter of complaint against ELMs: http://theanonymousemail.com/view/?msg=ZHEZJ1AJ that I thought you might find interesting. > On May 7, 2015, at 1:10 A

What Sebastian and Ronnie said. Plus: there are multiple off-the-shelf neural net pull requests in the process of review, notably those by Issam Laradji for GSoC 2014. Extreme Learning Machines and Multilayer Perceptrons should be merged Real Soon Now. On 7 May 2015 at 14:58, Ronnie Ghose wrote:

I am not one of the core developers, just a typical user, but although I think that neural nets would be a nice addition, I have to admit that I wouldn't count them as top priority. I think that in applications, neural networks require far more flexibility for tweaking than the "classic" off-the

I used to seeking neural network algorithms in sklearn, but I just found a RBF in it. There are plenty of Neural Network algorithms, why dose we only support RBF which is not even a typical neural network ? I thought the neural networks should be the largest family amount sklearn algoritms, but it

Hi Luca, Is it because of the number of trees? In R you're using 10 trees and in python 20 trees. Can you provide the output of your algorithm? You only provided the output of R. Regards, On Thu, May 7, 2015 at 1:54 AM, Andreas Mueller wrote: > https://github.com/scikit-learn/scikit-lear
