Dalam snapshot, kita menggunakan entropy-MDL discretization, yang menentukan jumlah interval optimal secara otomatis; kita bisa melihatnya mendiskreditkan usia menjadi tujuh interval dengan cut-off di 21.50, 23.50, 27.50, 35.50, 43.50, 54.50 dan 61.50, sementara capital-gain dibagi menjadi banyak interval dengan beberapa cut-off. Final weight (fnlwgt), misalnya, dibiarkan dengan interval tunggal dan dengan demikian dihapus. Di sebelah kanan, kita dapat memilih metode diskritisasi khusus untuk setiap atribut. Atribut “fnlwgt” akan dihapus oleh MDL-based discretization, jadi untuk mencegahnya dihapus, kita memilih atribut dan memilih, misalnya, diskritisasi frekuensi sama. Kita juga dapat memilih untuk membiarkan atribut continuous..
