お待たせしました。Version 2.0.0から随分と時間掛かってしまって申し訳ないです。今回のバージョンからML.NETモデルビルダーで学習させたモデルに変更を行ってます。具体的には血統情報(父、母等)をこれまでfloat(single)だった所を文字列(string)に変えてます。JRA-VANの血統登録番号は10桁なんですが、単精度実数では10桁保持出来ない事に気が付いての修正なんですが、AutoMLではこの修正が上手く出来ずに変更してません。元々モデルビルダーとAutoMLでは出来上がるモデルは違ってましたが、今回の変更で更に違ってくるかと思います。
以前のバージョンの学習モデルは指定するとエラーとなります。独自に学習させたユーザー様には申し訳ないですが、添付されているモデルを利用されるか、再度学習させて頂く必要があります。
今回の学習モデルは2004.1.1～2024.12.31のデータを使って学習させてます。2025.1.1～2025.2.28とちょっと短い期間でしか検証出来ませんが以下の様なモデルとなってます。思う様に学習精度が上がらず、それもリリースが遅れた原因の一つなんですが、時間を掛けて納得のいくモデルを見つけて頂ければと思います。

検証期間が短い中でたまたま大きいのが当たってたりして回収率がだいぶ良く見えますが、的中率的にはまだまだなんで、その辺り十分に気を付けて下さい。
