[GitHub] flink pull request: [FLINK-3742] Add Multilayer Perceptron
GitHub user rawkintrevo opened a pull request:

[FLINK-3742] Add Multilayer Perceptron
https://en.wikipedia.org/wiki/Multilayer_perceptron
Multilayer perceptron is a simple sort of artificial neural network. It creates a directed graph in which the edges are parameter weights and nodes are non-linear activation functions. It is solved via a method known as back propagation.
I anticipate this being an ongoing thing for a bit. I'll be working on docs in the meantime and commit soon.
A note on the tests. Neural-nets take a while to fit by their nature. I recommend using the warm starts and verifying that it is getting closer after a few batches of iterations, and some other tests for the unit functionality (winding/unwinding parameter matrix arrays, etc.)

Interesting. I still need to add some docs and squash my commits. I'll do that in the next day or two and retrigger the CI build- maybe the issue will have magically solved itself by then?
Good looking out btw, and thanks!
