タスク説明

人間は視覚を通じてパッケージを見て食料と飲料を判断し、それに基づいて分別を行っています。しかし機械の処理技術では分類が難しく、人間による判別が行われることが多いです。

食品を生産・管理する工場において食料と飲料の適切な分類は、工程や物流の最適化、在庫管理などにおいて重要な要素であり、高精度な分類モデルの開発は食料品の生産・管理の効率向上に寄与することが期待されます。そこで、本コンペでは、食料品の工場向けのデータ分析を想定し、機械学習の手法などを用いて商品のパッケージが映った画像を食料か飲料に自動分類するアルゴリズムを構築していただきます。


予測対象は商品画像となります。

分析用データとして、商品のパッケージが映された画像データと対応する情報(飲料・食料)が与えられます。

▼提供データ

・商品のパッケージを写した画像データ
・飲料、または食料かどうかに関する情報


▼一般部門・学生部門について

一般部門・学生部門では2部門をご用意しています。どちらの部門も課題や提供データは同じですが、懸賞内容が異なります。

一般部門 = 腕に自信のある学生の方・初心者の社会人の方が対象
学生部門 = 学生の方が対象

参加はいずれか1部門のみとなりますので、データダウンロード時に表示される応募フォーム内で、希望の部門を選択してください。
なお、リーダーボードは両部門を総合して表示されますが、ユーザーの皆様がどちらの部門に参加表明されたかが分かるよう、部門名のフラグが表示されます。

※一度部門を選択すると変更はできません。
※社会人であるにも関わらず「学生の部」を選択された場合は、入賞資格の取り消しとなります。

また、学生の方は一般部門にも参加できますが、その場合は、一般部門の参加者内で順位が決まりますのでご注意ください。
なお、メダル・ポイントは一般部門・学生部門の区別なく決定します。

評価方法

  • 精度評価は、AUC(Area Under the Curve)を使用します。
  • 評価値は0以上の値をとり、精度が高いほど1に近づきます。

リーダーボードのスコアは上記評価関数にて実施しますが、本コンペでは解を得るためのプロセスを重視します。
このため、入賞候補者の選定にスコアを利用しますが、最終的な入賞者は審査発表会での審査にて決定いたします。

入賞者決定の流れ

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。
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、早い日時でご応募いただいた参加者を上位とします。

3. リーダーボードの順位が上位の方から、「一般部門」・「学生部門」のそれぞれ上位10名ずつ、計20チームを入賞候補者とし、テクノプロ・デザイン社から連絡いたします。

4. 入賞候補者には、10/14（土） に開催予定のオンラインの審査発表会にて解法プレゼンテーションを行って頂きます。下記審査観点の内容を踏まえた資料作成をお願いします。

5. プレゼンテーションの内容を元にテクノプロ・デザイン社により審査を行い、入賞者及び最終順位を決定します。

　　▼審査観点
　　・スコアの結果
　　・基礎集計で得られた知見
　　・実施した前処理とそれを行った理由
