Q1:スクレイピングで取得した中古車データを学習データとして利用することは外部データに当たりますか?
A1:外部データに該当します。
Q2:geopyなどの地域から緯度・経度を取得できるライブライの使用は外部データに該当しますか?
A2:外部データに該当致しません。本コンペティションでは緯度・経度に限り利用可能としております。
Q3:地域(region)から州(state)を特定できることがわかりました。このためregionがどこのstateに属するかをインターネットで調べ、regionとstateの関係性を辞書にまとめstateの情報を修正しました。こちらは外部データ利用に該当しますか?
A3:外部データに該当致しません。こちら知見を用いて特徴量を作成したと判断します。
Q4:Q3が外部データに該当しない(知見を用いた特徴量作成行為)のであれば、stateごとの地価や気候などを調べ、新たに特徴量を追加することは知見を用いた行為であり外部データに該当しないのでしょうか?
A4:こちら知見を用いて特徴量を作成したと判断できますが、外部データに該当致します。
Q5:Q3とQ4で外部データに該当する・しないの違いは何でしょうか?
A5:Q3はregionからstateを特定しています。regionとstateはお互い配布データ内に特徴量として含まれているので、外部データの利用に抵触しません。
一方でQ4は「地価」や「気温」に該当する特徴量が配布データ内に含まれていないので、外部データに該当します。
Q6:toyota、nissanは日本車であるなどの製造メーカーの国に応じて新たな特徴量を作成したいです。ですが製造メーカーの国に関する特徴量は配布データにないことを踏まえると、特徴量は使用できないのでしょうか?
A6:利用できます。配布データ内での特徴量から、特徴量エンジニアリング・一定のロジック・アルゴリズムによって、新たな特徴量を作成できた場合、外部データの利用に該当致しません。ですが検証時に、新たな特徴量を作成したロジックが不明瞭で外部データの利用が疑われる場合、事務局から質問する場合がございます。回答の内容で疑いが解消されない場合、入賞を取り消す可能性がありますのでご注意ください。
Q7:配布データに外部データを追加し、EDAをする行為は外部データに該当しませんか?
A7:モデルの学習に外部データを利用していなければ、外部データを追加してEDAを行う行為はルールに違反しません。こちらルール違反となる根拠を事務局がつかめないためです。
Q1:「評価用データを利用・参考にして、学習用データの修正・特徴量の追加を行い、モデルの学習・推論を行うことを禁じます。」とありますが、訓練用データと評価用データの分布の違いやカテゴリの違いをなどを確認する行為はこのルールに抵触しますか?
A1:ルール違反に該当致しません。こちら事務局での判断が難しいためとなります。
Q2:評価用データと訓練用データの分布が異なるため、評価用データの分布を訓練用データの分布に合わせ加工し、推論する行為はルール違反に該当しますか?
A2:こちら該当致しません。反対に評価用データに合わせて学習用データを修正する行為はルール違反に該当致します。
Q3:訓練用データと評価用データを結合し特徴量を集約、集約したデータを特徴量として利用し学習する行為はルール違反に該当しますか?
A3:該当致します。
Q4:テストデータに予測値を加えたデータを追加データとして、モデルに学習させる行為(pseudo-labeling)は評価データの利用に該当しますか?
A4:こちら該当致しますので、ルール違反となります。
