Is Your Model’s Log-Loss Better Than Random Guessing Log-Loss?
In machine learning and mathematical optimization, loss functions for classification are computationally feasible loss functions representing the price paid for inaccuracy of predictions in classification problems (problems of identifying which category a particular observation belongs to). Given See more Utilizing Bayes' theorem, it can be shown that the optimal $${\displaystyle f_{0/1}^{*}}$$, i.e., the one that minimizes the expected risk associated with the zero-one loss, implements the Bayes optimal decision rule for a … See more The logistic loss function can be generated using (2) and Table-I as follows The logistic loss is … See more The Savage loss can be generated using (2) and Table-I as follows The Savage loss is quasi-convex and is bounded for large … See more The hinge loss function is defined with $${\displaystyle \phi (\upsilon )=\max(0,1-\upsilon )=[1-\upsilon ]_{+}}$$, where $${\displaystyle [a]_{+}=\max(0,a)}$$ is the positive part See more The exponential loss function can be generated using (2) and Table-I as follows The exponential … See more The Tangent loss can be generated using (2) and Table-I as follows The Tangent loss is quasi-convex and is bounded for large negative values which makes it less sensitive to outliers. Interestingly, the … See more The generalized smooth hinge loss function with parameter $${\displaystyle \alpha }$$ is defined as See more WebComputes the cross-entropy loss between true labels and predicted labels.
