▼タスク説明

本コンペティションでは旅行会社の保有する顧客データ(属性や志向、営業担当との接触履歴等)を元に、旅行パッケージの成約率を予測するモデルを構築していただきます。

あなたは旅行会社のデータサイエンティストです。会社では、マーケティング活動を通じて旅行パッケージの販売を行っています。

これまでの経験から、旅行パッケージを購入しやすい人とそうでない人の傾向はなんとなく分かっていましたが、データの活用は十分ではなく、マーケティングコストが高くついていることが問題でした。そこで、機械学習を使って旅行パッケージを購入しそうな顧客を予測し、マーケティング戦略に活用することを決めました。

各部署から使えそうなデータを集めたあなたは、早速予測モデルの開発に取り掛かりました。しかし、データベースの度重なる仕様変更などにより、データは綺麗に構造化されていません。そこで、まずはデータを整形し、予測モデルの構築に取り組むことにしました。

※正解データがリークしないよう、データは実際のデータを元に生成した合成データを使用しております。実際のデータに合わせて作成・検証をしていますが、分析に支障が出るような問題点があればお知らせください。
※実際のビジネスの場では、常にデータが綺麗な状態にあるとは限りません。本データでは、データに意図的にノイズや表記揺れを付与しています。さまざまなデータ処理や特徴量エンジニアリング、機械学習アルゴリズムをお試しいただき、高精度のモデル構築にチャレンジしてください。
※評価用データの内、暫定評価と最終評価に使用するデータの割合は、5:5としています。



▼評価関数

  • 精度評価は、評価関数AUC(Area Under the Curve)を使用します。
  • AUCはROC曲線の下の面積を表し、0から1の値を取ります。
  • AUCの値が1に近いほど、モデルの予測精度が高いことを示します。
  • 一般に、ランダムな予測ではAUCの値は0.5となります。
  • AUCの値が0.5を下回る場合、モデルの予測は逆に外れている可能性が高いことを示します。


▼最終順位の決定

  1. コンペ最終日までの評価(暫定評価)は評価用データセットの一部で評価し、コンペ終了後の評価(最終評価)は評価用データセットの残りの部分で評価します。
    暫定評価は評価用データセット全体の50%、最終評価は評価用データセット全体の50%となります。
    リーダーボードはコンテスト終了時に自動的に最終評価に切り替わり、それを元に最終順位を決定します。このため、開催中と終了後では順位が大きく変動する場合もあります。
  2. スコアが同値の場合は、早い日時でご応募いただいた参加者を上位とします。
※不正が発覚した場合は、SIGNATE独自の裁量により、メダル・ポイントが付与されない場合があります。
