For supervised problems, where data instances are annotated with class labels, we would like to know which are the most informative features. Rank widget provides a table of features and their informativity scores, and supports manual feature selection. In the workflow, we used it to find the best two features (of initial 79 from brown-selected dataset) and display its scatter plot.

Untuk masalah yang supervised, di mana instance data dijelaskan dengan class label, kita ingin tahu feature mana yang paling informatif. Widget Rank menyediakan tabel fitur dan skor informativitasnya, dan mendukung pemilihan fitur manual. Dalam workflow, kita menggunakannya untuk menemukan dua fitur terbaik (dari 79 awal dari dataset yang dipilih) dan menampilkan di widget Scatter Plot.
