Web15 de fev. de 2024 · February 15, 2024. Loss functions play an important role in any statistical model - they define an objective which the performance of the model is evaluated against and the parameters learned by the model are determined by minimizing a chosen loss function. Loss functions define what a good prediction is and isn’t. http://papers.neurips.cc/paper/7882-learning-to-teach-with-dynamic-loss-functions.pdf blu speed cell phone
