<ul data-eligibleForWebStory="true">Backpropagation is the learning algorithm used by most neural networks to update model weights after each prediction.It helps neural networks learn from mistakes by adjusting internal weights.The process is similar to correcting a student's mistake and allowing them to improve.Backpropagation allows the network to adjust internal weights in the right direction.Steps in backpropagation involve input data passing through network layers, making predictions, and comparing them to actual labels.A loss function like MSE or Cross-Entropy quantifies how wrong the model's prediction was.Weights are adjusted based on minimizing the loss, and this cycle repeats for the next batch of data.Analogies like a thermostat adjusting room temperature help understand the concept of backpropagation.Backpropagation is essential for deep learning models to learn and improve over time.It guides the network in tweaking internal weights to get closer to correct values.Backpropagation is the foundation of how deep learning models improve their decisions over time.
