답변:Harsh2024년 10월 7일 Hello, I have created an SVM-Linear kernel algorithm script on MATLAB for classification of my data. The training gives 98% of validation accuracy and also the prediction for
MATLABSVM classificationLiver cancer is one among the normal types of cancer. Detection and determination of liver tumor at early stage are vital. The vast majority of the cancer passings can be anticipated by early detection, determination, and compelling treatment. It is required to fragment the...

In other words, the software attempts to remove 100p% of the observations when the optimization algorithm converges. The removed observations correspond to gradients that are large in magnitude. If your predictor data contains categorical variables, then the software generally uses full dummy encoding ...

Determine how well the algorithm generalizes by estimating the test sample classification error. Get L = loss(CompactSVMModel,XTest,YTest) L = 0.0787 The SVM classifier misclassifies approximately 8% of the test sample. Determine Test Sample Hinge Loss of SVM Classifiers Copy Code Copy Command...
In this workflow, you define the fixed-point data types by using the data type function generated from generateLearnerDataTypeFcn. Separating data types of the variables from the algorithm makes testing simpler. You can programmatically toggle data types between floating-point and fixed-point by usi...
