Methods of prognostic prediction and classification,such as classification of disease,are commonly used to assist decision-making in clinical management.Multiple classification methods are often available for the same disease population.Comparison of these methods is necessary to identify the optimum classific...
RSM uses multivariate decision theory to classify individuals, and NNM, considered as a nonlinear regression method, uses the middle layer of the network structure as classification results. We have found some similarities and differences between the results from the two approaches, and moreover both...
Urban remote sensing classification is the foundation of extracting urban vegetation distribution.However,urban classification accuracy is very low because of mixed pixels.Therefore,mixed pixel decomposing model with neural network(MPD-NN) is proposed to classify TM image in Beijing.Then the classification...
Grain-size class-Std(GSCStd) and Grain-size class-dD(GSCdD) methods are simple statistical approaches for classifying bulk grain-size distributions(GSDs) into grain-size fractions. Although these two methods were developed based on similar statistical principles, the classification difference between th...
Part of the book series: Studies in Classification, Data Analysis, and Knowledge Organization ((STUDIES CLASS)) 2782 Accesses Abstract Consensus methods are widely used to combine hierarchies defined on a common set of n object. Many methods have been proposed during the last decade to combine ...
Objective: To compare how at-risk tissue and core infarction were defined in two major trials that tested the use of MRI in selecting acute stroke patients for endovascular recanalization therapy. Methods: MRIs from 12 patients evaluated for possible endovascular therapy were processed using the meth...
In this segment-based classification task, we propose the mask attention mechanism (MA) which uses the predicted masks at the first stage as spatial attention maps to adjust the features of the CNN at the second stage. The MA spatial attention maps for features calculate the percentage of ...
