Question
What is the weight update rule in backpropagation?Select one:a.W(i, j) = W(i, j) - alpha * delta(i) * output(j)b.W(i, j) = W(i, j) + alpha * delta(i) * output(j)c.W(i, j) = W(i, j) / alpha * delta(i) * output(j)d.W(i, j) = W(i, j) * alpha * delta(i) * output(j)
Solution
The correct answer is:
b. W(i, j) = W(i, j) + alpha * delta(i) * output(j)
This is the weight update rule in backpropagation. Here, W(i, j) is the weight between the i-th and j-th neuron, alpha is the learning rate, delta(i) is the error term for the i-th neuron, and output(j) is the output of the j-th neuron. The rule states that the new weight is the old weight plus the product of the learning rate, the error term, and the output.
