tall 配列に対する回帰木の最適化
tall 配列を使用する回帰木のハイパーパラメーターを自動的に最適化します。標本データ セットは carsmall データ セットです。この例では、データ セットを tall 配列に変換して、最適化手順を実行するために使用します。
tall 配列に対する計算を実行する場合、MATLAB® は並列プール (Parallel Computing Toolbox™ がある場合は既定) またはローカルの MATLAB セッションを使用します。Parallel Computing Toolbox がある場合でもローカルの MATLAB セッションを使用して例を実行するには、関数mapreducerを使用してグローバルな実行環境を変更できます。
carsmall データ セットを読み込みます。Displacement、Horsepower および Weight が応答 MPG の予測子であると考えます。
load carsmall
X = [Displacement Horsepower Weight];インメモリ配列 X および MPG を tall 配列に変換します。
tx = tall(X); ty = tall(MPG);
名前と値の引数 OptimizeHyperparameters を使用して、自動的にハイパーパラメーターを最適化します。ホールドアウト交差検証損失が最小になる最適な MinLeafSize の値を求めます。("auto" を指定すると MinLeafSize が使用されます。) 再現性を得るため、"expected-improvement-plus" の獲得関数を使用し、rng と tallrng により乱数発生器のシードを設定します。tall 配列の場合、ワーカーの個数と実行環境によって結果が異なる可能性があります。詳細については、コードの実行場所の制御を参照してください。
rng("default") tallrng("default") [Mdl,~,HyperparameterOptimizationResults] = fitrtree(tx,ty, ... OptimizeHyperparameters="auto", ... HyperparameterOptimizationOptions=struct(Holdout=0.3, ... AcquisitionFunctionName="expected-improvement-plus"))

学習させたモデル Mdl は、最適な推定実行可能点に対応し、MinLeafSize に同じハイパーパラメーター値を使用しています。
bestPoint 関数を使用して、Mdl の学習に使用されたハイパーパラメーター値を調べます。既定では、bestPoint は、ハイパーパラメーターの最適化時に fitrtree で使用されたものと同じ最適点の基準 ("min-visited-upper-confidence-interval") を使用します。一般に、近似関数では、データ セット内のノイズへの過適合を防ぐために、基準 "min-visited-upper-confidence-interval" (基準 "min-observed" ではなく) に基づいて最適なハイパーパラメーター値を判別します。
