Classifier confidence

Dec 29, 2021

Jan 18, 2016 The proposed Classification Confidence-based Multiple Classifier Approach (CCMCA) is applicable for multi-class texture classification. The CCMCA method is built upon only two base classifiers such as Neural Network (classifier C1) and Naive Bayes (classifier C2) and therefore, involves less complexity

Classification Confidence. The RDP classifier used a bootstrapping method of randomly subsampling the words in the sequence to determine the classification confidence. This bootstrapping procedure is not performed in ClassifyReads. This change is primarily due to performance reasons (bootstrapping slowed the algorithm down by 20–50 ) and

Nov 17, 2021 Randomized smoothing is currently a state-of-the-art method to construct a certifiably robust classifier from neural networks against $\\ell_2$-adversarial perturbations. Under the paradigm, the robustness of a classifier is aligned with the prediction confidence, i.e., the higher confidence from a smoothed classifier implies the better robustness. This
