エピソード遷移統計

成功エピソードと失敗エピソードでの遷移パターンを分離して記録。 Q-learning風の価値関数近似に活用可能。

Fields

success_transitions: HashMap<(String, String), u32>

成功エピソードでの遷移カウント (prev_action, action) → count

failure_transitions: HashMap<(String, String), u32>

失敗エピソードでの遷移カウント (prev_action, action) → count

success_episodes: u32

成功エピソード数

failure_episodes: u32

失敗エピソード数
