Neural networks
What is a neural network?
Maybe this?
...or this?
But all more simpler
(simple neural network with 2 input and 5 hidden layers)
Structure of neural network
Structure of NN
Sinapse
Take the value from the input, multiply by specific weight and output the result.
Neurons
Their job is to act together the output from other synapse and apply the activation function
(sigmoid activation function)
Neurons
And the apply the activation function to every neuron
Training of neural network
Error of NN
Cost function
Training rule
Gradient descent
