Squared Error Method

Squared error is a loss function used in machine learning and generative AI to train models to make predictions based on data. MAE reduces average error while MSE does not, and PSNR is no longer considered a reliable indicator of image quality degradation with SSIM emerging as a more suitable metric for assessing image improvements. The squared error loss function is often used in regression tasks and is sensitive to outliers and can be affected by the input/output data scale.
