k_fold 样本 SVM 的价值下降 class

Question

我对 C# 中 SVM class 的 k_fold 值有疑问（使用 emgucv）。所有的数字值都只是例外，如下所示：

Emgu.CV.Util.CvException was unhandled HResult=-2146233088
Message=OpenCV: While cross-validation one or more of the classes have been fell out of the sample. Try to enlarge
Source=Emgu.CV ErrorMessage=While cross-validation one or more of the classes have been fell out of the sample. Try to enlarge

放大/更改 k_fold 值无用。请帮我解决它们？

Answer 1

用它来解决model.Train(datalatih, kelas, null, null, s)。这是我的代码

using (SVM model = new SVM())
            {
                SVMParams s = new SVMParams();
                s.KernelType = Emgu.CV.ML.MlEnum.SVM_KERNEL_TYPE.LINEAR;
                s.SVMType = Emgu.CV.ML.MlEnum.SVM_TYPE.C_SVC;
                s.C = 1;
                s.TermCrit = new MCvTermCriteria(100, 0.00001);

                // Lakukan pelatihan
                model.Train(datalatih, kelas, null, null, s);

                // Tes Uji SVM
                for (int i = 0; i < 30; i++)
                {
                    datauji.Data[0, i] = uji[i];
                }
                float hasil = model.Predict(datauji);

                return Tuple.Create((int)hasil);
            }
