A lighthouse lens room walks through one training step on a cracked-prism still plus a short keeper note. Which statement correctly separates the two halves of that step?
Select an answer to reveal the explanation.
Short Explanation
Picture a two-way street: outbound traffic is the guess, inbound traffic is the correction. The forward pass only predicts; the backward pass sends the error home so weights can shift. Mixing those jobs muddles how one training step works.
Full Explanation
In a standard training step, the forward pass computes the model’s prediction from the multimodal inputs. The loss compares that prediction to the target, and the backward pass propagates gradients so parameters can update. The forward half does not itself apply the weight change.
