Neural Network Recap
• A Neural Network is a function!
• It (generally) comprised of:
• Neurons which pass input values through functions and output the result
• Weights which carry values between neurons
• We group neurons into layers. There are 3 main types of layers:
• Input Layer
• Hidden Layer
• Output Layer
• Train a Neural Network = Find good Weights:
θ = argminθ
loss(y (x ), hθ (x ))
