NMF applied to Wikipedia articles

In the video, you saw NMF applied to transform a toy word-frequency array. Now it's your turn to apply NMF, this time using the tf-idf word-frequency array of Wikipedia articles, given as a csr matrix articles. Here, fit the model and transform the articles. In the next exercise, you'll explore the result.

Import NMF from sklearn.decomposition.
Create an NMF instance called model with 6 components.
Fit the model to the word count data articles.
Use the .transform() method of model to transform articles, and assign the result to nmf_features.
Print nmf_features to get a first idea what it looks like.
