Web2 de nov. de 2024 · Our loss function has two properties. (1) When the sample classification is inaccurate and is relatively small, approaches 1 and no impact on loss occurs. When tends to 1, approaches 0 and there is a loss decline of well-classified samples. (2) The parameter expands differences among various samples.
