Squared error loss is one of the most widely used loss functions in statistics , though its widespread use stems more from mathematical convenience than considerations of actual loss in applications. Carl Friedrich Gauss, who introduced the use of mean squared error, was aware of its arbitrariness and was in agreement with objections to it on these grounds. The mathematical benefits of mean squared error are particularly evident in its use at analyzing the performance of linear … WebThe symmetric interval around the mean will minimize the maximum expected quadratic loss within the credible set (because it is symmetric). It will not minimize the average expected quadratic loss in the set, but you could also construct a credible set with that property. – Mikkel N.

WebAug 14, 2024 · A quadratic function only has a global minimum. Since there are no local minima, we will never get stuck in one. Hence, it is always guaranteed that Gradient Descent will converge ( if it converges at all) to the global minimum. The MSE loss function penalizes the model for making large errors by squaring them. WebWhen the loss is quadratic, the expected value of the loss (the risk) is called Mean Squared Error (MSE). The quadratic loss is immensely popular because it often allows us to …
