Questions & Step-by-Step Solutions

Which optimization algorithm is commonly used to update weights in neural networks?
  • Step 1: Understand that neural networks learn by adjusting their weights.
  • Step 2: Know that weights are updated to minimize the difference between predicted and actual outcomes.
  • Step 3: Learn that the process of updating weights is guided by a method called an optimization algorithm.
  • Step 4: Identify Stochastic Gradient Descent (SGD) as a common optimization algorithm.
  • Step 5: Realize that SGD updates weights based on the gradient (slope) of the loss function, which measures how well the network is performing.
