Inequalities in data world

In the schools days, for me, equations with equals itself were so hard to think. 2x + 5 = 0. Wow somebody got mad. 2 and 5 are already greater than 0 and then this equation. No wonder my mind never reached inquality equations.

But when I see at an inequality equation like y < 2x + 1 and its graph

it generates such overwhelming emotions. I can bisect the sky and say the stars on right developed certain feature once a certain period passed after big bang and start on left showed certain features.

Or something like this

An inequality equation defines the data in a certain way on one side and another way on other side. Simple!!!

And how about bunch of inqualities working together. You have a neural network. No brainer. :)

Have a look once again
