スケートボーダー重心位置予測チャレンジ

課題内容

スケートボードランプのLEDサイン側滑走時において、スケートボーダーの重心(XYZ空間での速度)データ付きの下肢の皮膚表面から記録された生体信号データ(16チャンネル)を用いて、ランプ逆側滑走時における運動状態(重心の速度)の時系列を重心データのない生体信号データから予測していただきます。

また、リファレンスデータとして、被験者1名分の全区間につき、重心速度データ付きの生体信号データ(16チャンネル)も提供します。

なお、コンテスト終了時(予測結果の投稿締切時)のリーダーボードの最終評価が上位15位以内の方には、考察レポート(詳細は決定次第ご案内します)を提出いただきます。

精度評価に使用する評価関数

  • 各時点における回帰結果と正解データについて、評価関数3次元RMSE(Root Mean Squared Error 3D)により評価します。
  • 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。
  • Kは被験者の総数、Tは被験者当たりの試行の総数、Pは各試行の時点の総数を表します。また、vk,t,pは被験者kのt回目試行におけるp時点での3次元の重心速度の予測値を表し、 v'k,t,pは被験者kのt回目試行におけるp時点での3次元の重心速度の実測値を表します。

入賞者決定の流れ

  1. コンテスト最終日までの評価(暫定評価)は評価用データセットの一部で評価し、コンテスト終了後の評価(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。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。
    ※投稿ファイルは最大2つまで選択可能で、最終評価のスコアの高いファイルが自動的に採用されます。
  2. スコアが同値の場合は、リーダーボードでは早い日時でご応募いただいた参加者が上位として表示されますが、最終順位が5位のスコアと同値の方が複数いる場合は、その方も入賞候補者とします。同様に最終順位が15位のスコアと同値の方が複数いる場合は、その方も審査員特別賞の候補とします。
