Little brain teaser I was sent today. In case you are thinking of going to tech, a taste of the "entertainment" you will see. I'm surround by nerds.

Your advisor has left you in charge. A pesky grad student comes up to you and states that they have developed a new Neural Net. Each perceptron in the Net has an output that is a summation of its weighted inputs (no thresholds).

You yawn and state that the Net is uninteresting. Why?

(No, its not because you haven't been getting enough sleep)
