学習データの指数変換実装例

ここでは、Rastrigin 関数のブラックボックス最適化例に対して、「transformation.md」に記載の目的関数値の指数変換を考慮して最適化を行います。

ブラックボックス関数及び初期学習データの準備

指数変換を実施するには、初期学習データにおけるブラックボックス関数値に基づき、変換パラメータ \(c_m\) を決定する必要があります。これを実現するために、Optimizer.add_random_training_data による初期学習データ生成は行わず、@blackbox デコレータ―によるブラックボックス関数の生成前に初期学習データを生成 → 変換パラメータを算出 → データをスケーリング → 指数変換を考慮した評価値を出力するブラックボックス関数、という順序で実装を行います。

最適化の実行

最適化で利用するイジングマシン (Fixstars Amplify Annealing Engine (Amplify AE))をソルバークライアントとして設定します。ここでは、一度のアニーリング時間を 2 秒と設定します。

予め準備したブラックボックス関数と初期学習データ、ソルバークライアントを使い、最適化クラスのインスタンス化を行います。

optimize() を使って最適化サイクルを実行します。

from amplify import FixstarsClient
from amplify_bbopt import KMTrainer, Optimizer

# イジングマシンの設定
client = FixstarsClient()
client.parameters.timeout = timedelta(seconds=2)
# client.token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"  # ローカル環境等で使用する場合は、Amplify AEのアクセストークンを入力してください。

# 最適化クラスのインスタンス化
optimizer = Optimizer(
    blackbox=func,
    trainer=KMTrainer(),
    client=client,
    training_data=Dataset(init_x, init_y_scaled),
)

# 最適化を実行
optimizer.optimize(num_iterations=100)
