FusedOrthogonalAlternatingLeastSquaresfor TensorClustering
Our paper adopts the CP decomposition because it handles heterogeneity in each mode, learns the clustering patterns across different modes of data in amore independent way, and provides flexibility for clustering a certain mode of the tensor without being affected by correlation with other modes. Our method is similar to those in a recent series of papers [27, 21] that use the CP decomposition structure. Note that their estimation algorithms use the framework oftensor power method [1].
Towards Calibrated Model for Long-Tailed Visual Recognition from Prior Perspective - Supplementary Material - Zhengzhuo Xu
One the one hand, the classification performance will be promoted. F ollow the settings of Proof A.2 and Eq.6, we can get the following relationship of the Hence we can generalize Eq.A.9 to: y According to Eq.A.11, it's easy to find a derivative zero point in range [1,C]. F ollow the Basic Setting of Proof.1, suppose It has limited contribution for the tail class' feature LT scenarios, the likelihood is consistent in the train and test set, but the prior is different. Hence, the actual optimization direction is not described as Eq.B.2 because the bias incurred by According to LemmaB.1, we immediately deduce that Bayias-compensated cross-entropy loss ensures All above re-weight methods are proven effective empirically, more or less. They propose the LDAM loss to encourage the tail classes to enjoy larger margins.
