Splet30. dec. 2024 · 支持向量回归（SVR）是一种回归算法，它应用支持向量机（SVM）的类似技术进行回归分析。 正如我们所知，回归数据包含连续的实数。 为了拟合这种类型的数据，SVR模型在考虑到模型的复杂性和错误率的情况下，用一个叫做ε管（epsilon-tube，ε表示管子的宽度）的给定余量来接近最佳值。 在本教程中，我们将通过在 Python 中使用 … Splet27. jul. 2024 · In scikit-learn, this can be done using the following lines of code. # Create a linear SVM classifier with C = 1 clf = svm.SVC (kernel='linear', C=1) If you set C to be a low value (say 1), the SVM classifier will choose a large margin decision boundary at the expense of larger number of misclassifications. When C is set to a high value (say ...
