• Simple (antiquated) Answer: A neural network is a mathematical tool, loosly inspired by neural the connections in the brain, to make a decision based on complicated input.
• A Better Answer: A tool from machine learning for doing nonlinear classification and regression.

If you were given a new \((x,y)\) ordered pair, how would you classify it? Could you write a rule that a computer could understand?

• Select the correct data set
• Select the amount of noise
• Select an architecture

• Press the large play button

• Your goal is to get a neural network that is able to classify data such as this.

• Put questions on the board as they arise in your group.
