予測部門共通の注意事項について
今回、配布データに関して自由度の高いデータを提供しています。
そのため、モデリングを行う前にタブ「予測部門の共通注意事項」から注意事項を必ずご確認ください


総合ランキング
・本部門は、総合ランキング(スコア・メダル)の対象です。

評価関数

・精度評価は、評価関数「multi-class logloss」を使用します。

・Loglossをマルチクラス分類に拡張したものとなります。

・各クラスの予測確率を算出し、各々のレコードが属するクラスの予測確率の対数をとり、符号を反転させた値がスコアとなります。

・評価値は0以上の値をとり、精度が高いほど小さな値となります。

  

応募方法
・応募ファイルの形式はcsv (カンマ区切り) のヘッダーなしファイルです。
・応募ファイルの1列目にインデックスを、2〜12列目に予測値を記述します。

※インデックスは、データ内連番とします。

実装方法
【球種予測部門】と【コース予測部門】では以下の実装方法を指定します

・モデルの学習に利用するツールは、オープン且つ無料なもの (python, R等) に限定。 
・提案した方法が一般的な環境において追加費用を伴わず、再現及び継続使用可能であることを保証すること。
 同じフォーマットで、異なるデータを入力した場合にも同様なロジックで予測できなければなりません。
・ソースコードは、以下のように、前処理・学習・予測の3つに分け、それぞれを実行すれば
 処理が進むように実装すること。 
 ①preprocess
  提供データを読み込み、データに前処理を施し、モデルに入力が可能な状態でファイル出力するモジュール。
  get_train_dataやget_test_dataのように、学習用と評価用を分けて、前処理を行う関数を定義してください。
  ※preprocessに渡す情報として、学習用データと評価用データを混在させることは可能ですが、
  get_train_dataで返す結果は前処理された学習用データ、get_test_dataで返す結果は前処理された
  評価用データとなるように、処理の内容を独立させて下さい。
 ②train
  ①で作成したファイルを読み込み、モデルを学習するモジュール。
  学習済みモデルや特徴量、クロスバリデーションの評価結果を出力する関数も定義してください。 
 ③predict
  ①で作成したテストデータ及び②で作成したモデルを読み込み、予測結果をファイルとして出力するモジュール。

投球毎のデータに対する注意点

今回のタスクは前投球以前のデータを元に、ある時点での球種やコースを予測可能なモデルを作成することとします。
そのため、予測モデルに与える特徴量として未来情報を予測アルゴリズムに与えることは禁止とします。
今回は自由度の高いデータを用いてのコンペティションとなっていることを注意しながら楽しんでいただければと思っております。
また、週単位や月単位での集約特徴量や、ラグ特徴量、window関数による特徴量などを作成する際には下記のような条件を注意してください。




選手毎のデータに対する注意点
今回のタスクは今後初出場する投手の球種やコースも予測可能なモデルであるような汎用性の高さを求めます
よって1選手単位の特徴量ではなく、様々な単位でまとめた選手の特徴を用いましょう。

悪い例
・選手ID_XXXXXはストレートのみ投げているので、選手ID_XXXXXのあるかのフラグ値を特徴量として追加した。
 → 選手ID_XXXXXが引退した場合、フラグ値は常に0となるため特徴量としての意味を失ってしまいます。

良い例

・年代別で投げる球種に違いが見られたため、投手の年齢(連続値)と年代(カテゴリ)を特徴量として追加した。
 → 年齢や年代単位でまとめられた選手の特徴量となるため、有効な特徴量となります。
