	~~On the~~ previous page ~~we discussed~~		The previous page ended by mentioning that neural net classifiers can fail for two independent reasons:

			# The neural network itself is ill-formulated, so no matter how much information is provided it cannot learn to solve the classification problem.
			# The input data is insufficient in quantity or format to solve the classification problem.

	Here is the full set of possible network inputs ~~we have here, which includes~~...		That said, we found that a single neuron with input from a single feature was sufficient to solve the previous classification problem. Let's try another one. Without changing anything yet, press the play button on the Tensorflow playground below and let it run for about 5 seconds, and then press pause...

			How'd it do? This time around is one neuron with input from ''a single feature'' (the dim1 data: AGE) performing still performing well in the separation task? If so, an orange-colored background should have formed behind the orange dots, while a blue-colored background should have formed behind the blue dots.

			It probably didn't do so well this time around, right?

			Reset Tensorflow and try adding more neurons, and add an additional layer with several neurons, and rerun.

			How'd it do? Still can't solve the classification problem right? Seems like we need to add an additional feature as input, let's try some of those. Here is the full set of possible network inputs...

			Start by running ''X''<sub>1</sub> and ''X''<sub>2</sub> together, just to see what happens. Then feel free to test out whatever combinations you think might work.
