WebPCA generates two dimensions, principal component 1 and principal component 2. Add the two PCA components along with the label to a data frame. pca_df = pd.DataFrame(data = pca_results, columns = ['pca_1', 'pca_2']) pca_df['label'] = Y. The label is required only for visualization. Plotting the PCA results WebApr 2, 2024 · However, several methods are available for working with sparse features, including removing features, using PCA, and feature hashing. Moreover, certain machine learning models like SVM, Logistic Regression, Lasso, Decision Tree, Random Forest, MLP, and k-nearest neighbors are well-suited for handling sparse data.
