We consider support vector machines for bi- nary classification. As opposed to most ap- proaches we use the number of support vec- tors (the "L0 norm") as a regularizing term instead of the L1 or L2 norms. In order to solve the optimization problem we use the cross entropy method to...

Past that, to do the classification, the values of the classification output spiking neurons are averaged over the time axis so as to have one number per class to plug into the softmax cross entropy loss for classification as we know it and we backpropagate. This means the ...

However, the utility of simple self-training procedures that may improve classification efficiency has not been fully investigated. Therefore, there are multiple outstanding questions in the utility of active and self-supervised learning approaches for cell type annotation, including (i) what performance...
Cross entropy and mean squared error are typical cost functions used to optimize classifier performance. The goal of the optimization is usually to achieve the best correct classification rate. However, for many two-class real-world problems, the ROC curve is a more meaningful performance measure....
Moreover, we analyze the cross-entropy loss function. For the purpose of model training, we set the equilibrium coefficients as follows: [β,α1,α2,α3,α4]=[0.1,1,0.2,0.2,0.2]. This paper presents the configuration of the experimental environment, which includes the utilization of an ...
The cross-dataset evaluation supports OnClass as a robust method for automated cell type classification in datasets with large numbers of unseen cell types. Fig. 4: Training with different datasets and proportions of unseen cell types highlights OnClass versatility and accuracy. a–d Heatmaps ...
