To update the weights of the connections between neurons in the hidden layers
Which of the following activation functions is most commonly used in the hidden layers of a multilayer perceptron?
Rectified Linear Unit (ReLU)
What is the purpose of tuning the hyperparameters of a multilayer perceptron?
To optimize the performance of the model on the validation or test data
What is the primary difference between a single-layer perceptron and a multilayer perceptron?
The ability to solve non-linear problems
Which of the following is a key hyperparameter that can be tuned to improve the performance of a multilayer perceptron?
The learning rate
What is the purpose of the input layer in a multilayer perceptron?
To distribute the input data to the neurons in the hidden layers
What is a key difference between Adaline and the standard perceptron in the learning phase?
In Adaline, weights are adjusted according to the weighted sum of the inputs, while in the standard perceptron, the net is passed to the activation function for weight adjustment.
What type of activation function does Adaline use?
Bipolar activation function
Which training algorithm does Adaline employ to minimize Mean-Squared Error during training?
Delta rule
What is adjusted during the training of an Adaline network?
Weights and bias
How does the architecture of Adaline differ from a standard perceptron?
Adaline has an extra feedback loop which compares actual output with desired output, unlike a standard perceptron.
What is initialized at the start of training in an Adaline network?
Weights, Bias, Learning rate
What is the purpose of adding the 'bias weight' in the perceptron algorithm?
To shift the activation function left or right on the number graph
How does the activation function in a multilayer perceptron differ from the classic perceptron?
The multilayer perceptron uses a variety of real-valued activation functions, while the classic perceptron uses a boolean step function
What is the role of backpropagation in training a multilayer perceptron?
Backpropagation is used to compute the gradients and update the weights of the multilayer perceptron
Which of the following is NOT a hyperparameter that can be tuned in a multilayer perceptron?
The number of hidden layers
How does the architecture of a multilayer perceptron differ from the classic single-layer perceptron?
The multilayer perceptron has multiple hidden layers, while the classic perceptron has a single output layer
What is the purpose of regularization techniques in training a multilayer perceptron?
Regularization is used to prevent overfitting by constraining the model complexity
