GitHub リポジトリ<a href="https://medium.com/media/d2b05459b56d9a4c385bb1fbf4736fac/href">https://medium.com/media/d2b05459b56d9a4c385bb1fbf4736fac/href</a> 重みのプルーニングとは重みのプルーニングが役立つ理由チュートリアルトレーニング後に量子化を行う今後TensorFlow Lite 各種モデルにおける結果

異なるモデルやタスクでの値をゼロにする割合（sparsity）とその結果。

動作の仕組みアルゴリズム

プルーニングを行わないテンソル（左）、1x1 のブロックでプルーニングを行ったテンソル（中央）、1x2 のブロックでプルーニングを行ったテンソル（右）の例。

プルーニングに使うランプアップ関数の例。ステップ 0 からステップ 100 までプルーニングを行うようにスケジューリングし、最終的に値をゼロにする割合を 90% とした場合。

チュートリアルドキュメント

テンソルにプルーニングを適用する様子を表したアニメーション。黒いセルは、ゼロでない重みが存在する場所を示す。トレーニングプロセスが進むにしたがって、値がゼロになる割合が増加する。
