SoftMax Inc knn algorithm

Effect <t>on</t> <t>shoulder</t> girdle stabilization exercise inclusion/exclusion from training data for OOD detection of the SPARS9x dataset on: ( a ) FCN Softmax activation; and ( b ) normalized <t>KNN</t> nearest neighbor distance. This figure highlights the resiliency to changes in training class inclusion/exclusion of the KNN algorithm compared to deep learning algorithms for detecting OOD data with this dataset. Note that, even though the mean Softmax activation decreases for the OOD data and increases for the in-distribution classes with shoulder girdle stabilization removed, there is still a slight decrease in AUROC (see Softmax Threshold of b).

Effect on shoulder girdle stabilization exercise inclusion/exclusion from training data for OOD detection of the SPARS9x dataset on: ( a ) FCN Softmax activation; and ( b ) normalized KNN nearest neighbor distance. This figure highlights the resiliency to changes in training class inclusion/exclusion of the KNN algorithm compared to deep learning algorithms for detecting OOD data with this dataset. Note that, even though the mean Softmax activation decreases for the OOD data and increases for the in-distribution classes with shoulder girdle stabilization removed, there is still a slight decrease in AUROC (see Softmax Threshold of b).

Article Snippet: This is seen as designating the cycling activity as IIN increased the AUROC of Softmax Thresholding from 0.60 to 0.86, but also increased KNN from 0.90 to 0.92. .. Conversely, in b, the KNN algorithm has no such issue with the shoulder girdle stabilization activity, so the advantage that the traditional algorithms have over Softmax cannot be explained by class confusion alone. ..
