Netflixは,ちょっと演出を加えて評価データを集めたりしてる.利用者は現状の推薦を受け入れることの方が多く探索をしないので,インターフェースは利用者への負荷ができるだけ軽いものがよい.
2015-09-16 19:26:20Spotify のフィードバックに応じた推薦は,行列分解,CBOW/Skipグラムなどのブログ記事・ニュースのNLP処理,CNNを使った音響処理 benanne.github.io/2014/08/05/spo… に,局所的なフィードバックを勾配ブースティングでスタッキングしてる
2015-09-16 19:26:28「利用者が返したフィードバックと,実際に利用者が消費するアイテムとは異なる」という知見は重要.アルゴリズムは人気,多様性,関連性のバランスを考えて設計.
