What is wrong?

Hi!

I'm trying to train a pretty simple neural network, but no matter what I do, I always get the same results/prediction.

I don't know what I'm doing wrong, I've tried every configuration possible...

How do we replicate the issue?

I don't know enough jsfiddle to setup one quickly, but here's a simplification of my code.

And as you'll see, the results are always the same, whatever the input.

Node Example 
  const brain = require("brain.js");
  const net = new brain.NeuralNetwork({});

  net.train([{
    input: {
      day: 1,
      month: 2,
      year: 2017
    },
    output: {
      '16': 1,
      '20': 1,
      '31': 1,
      '33': 1,
      '46': 1
    }
  },
  {
    input: {
      day: 27,
      month: 1,
      year: 2017
    },
    output: {

  const brain = require("brain.js");
  const net = new brain.NeuralNetwork({});

  net.train([
