Question: In a neural network, what does the term \'backpropagation\' refer to?

Options:

Correct Answer: The method of updating weights based on error

Solution:

Backpropagation is the algorithm used to update the weights of the network by calculating the gradient of the loss function.

In a neural network, what does the term 'backpropagation' refer to?

Step 1: Understand that a neural network learns by adjusting its weights.
Step 2: When the network makes a prediction, it calculates an error (loss) based on how far off the prediction is from the actual result.
Step 3: Backpropagation is the process of sending this error back through the network.
Step 4: During backpropagation, the algorithm calculates how much each weight contributed to the error.
Step 5: The algorithm then updates the weights to reduce the error in future predictions.
Step 6: This process is repeated many times with different data to improve the network's accuracy.

Backpropagation – Backpropagation is the algorithm used in neural networks to compute the gradient of the loss function with respect to the weights, allowing for the adjustment of weights to minimize the loss.
