3 cards from this section. Quick, good the night before a test.
What is forward propagation in a neural network?
Think of the pathway the data takes in the network.
Name one activation function.
Consider functions that add non-linearity.
What is the first step in a neural network's operations?
It's the process that begins when you enter input into the network.
True or False: The activation function is applied after the weighted sum.
Think about the order of operations in a neuron.
Design a simple neural network with an input layer of 2 neurons, 1 hidden layer with 2 neurons, and an output layer with 1 neuron. Describe the forward propagation process.
Visualize the flow of data from input to output.
Consider a neural network with an input of values [1, 2, 3], weights [0.2, 0.8, 0.5], and bias 0.5. Calculate the output using a ReLU activation function.
Start with finding the weighted sum before applying the activation function.
