The bar chart tells us the proportion of variance explained by each of the principal components. On the other hand, the superimposed line chart gives us the cumulative sum of explained variance up until N-th principal component.
WebbThe scree plot shows that the eigenvalues start to form a straight line after the third principal component. If 84.1% is an adequate amount of variation explained in the data, then you should use the first three principal components. Step 2: Interpret each principal component in terms of the original variables
Webb12 apr. 2024 · First, we need to choose the right number of dimensions (i.e., the right number of principal components). For this, we apply PCA with the original number of dimensions (i.e., 784) and create the scree plot to see how well PCA captures the variance of the data.
