What type of units are used in the example of the AND function?
Bipolar units
What is the condition for the output of the perceptron to be 1?
The weighted sum is greater than the threshold
What is the problem with Hebbian learning?
It cannot learn nonlinearly separable functions
What is the purpose of the threshold θ in the perceptron?
To determine the output of the perceptron
What is the advantage of using bipolar units?
They can learn certain linearly separable functions more easily
What is the role of the bias unit in the Hebb net for the AND function?
It is used to introduce a constant input to the neuron
What is the purpose of the bias term b in the single layer neural network?
To represent the weight from a special unit with constant output 1
What is the update rule for the weights in Hebbian learning?
wij(new) = wij(old) + xi * y
What type of activation function is used for binary data in Hebbian learning?
Binary step function
What is the decision boundary in the case of n = 2, b != 0, and θ = 0?
A line
What is the key characteristic of error-driven learning?
Weights are updated based on the error between the predicted and actual output
What is the condition for the output of the neural network to be 1?
y_in ≥ θ
What is the condition for linear separability in a perceptron?
The data points can be separated by a single hyperplane
What is the Hebbian learning law in the context of Artificial Neural Networks?
wij increases only when both I and j are 'on'
What is the update rule for the weights in the Hebb net learning algorithm?
wij(new) = wij(old) + xi*y
How many times is each training sample used in the Hebb net for the AND function?
Once
What is the primary concept behind Hebb's claim in his book 'The Organization of Behavior'?
Behavior changes are primarily due to the changes of synaptic strengths between neurons
