This article introduces the log-cosh loss function as a smoother and more efficient alternative to the absolute error loss function in machine learning. It explains how log-cosh loss, derived from the hyperbolic cosine, offers advantages in terms of gradient behavior and approximation error compared to traditional methods like Mean Absolute Error (MAE). The piece positions log-cosh loss as a valuable tool for improving model training and performance. AI
