このチュートリアルでは、分析のためにデータを準備する例を示します。 データを準備することは、データマイニング・プロジェクトにおいて最も重要なステップの一つであり、伝統的に最も時間のかかるステップの一つである。 Auto Data Prep(オートデータプレパレーション)ノードは、データを分析し、修正点を特定し、問題のあるフィールドや有用でないフィールドを除外し、必要に応じて新しい属性を導き出し、インテリジェントなスクリーニング技術によってパフォーマンスを向上させます。
Auto Data Prepノードを完全に自動化された方法で使用し、ノードが修正を選択して適用することも、変更が加えられる前にプレビューし、それを受け入れるか拒否することもできます。 このノードを使用すると、関係する統計の概念を事前に把握していなくても、データ・マイニング用のデータを迅速かつ容易に準備できます。 デフォルトの設定でノードを動かすと、モデルの構築と得点が速くなる傾向がある。
