超える方法?

一時は複勝率6割目前まで来てたのに、新たな特徴量追加したからなのか遠のいてしまった。情報が多過ぎて把握しきれてないってか、頭が付いて行ってないorz ちょっと良さそうなモデルが出てもOOMで使えなかったり、32bitというJV-Linkの足枷が... 今やってる学習はそのモデルサイズを抑えてイテレーション数3,000、葉271、率0.008、分割数47、葉の最小50、ボーダー500、乗数1.0で、NDCG@1=0.7825 NDCG@3=0.7861というモデルは

やはりここ最近のレベルにとどまってる。この打開策として、そもそも追加した特徴量を無視させるか、新たな特徴量を追加するか。

追記 2026.6.28 8:38
CustomGainsでボーダーを入れた方がってAIの提案から入れてるのですが、どうも何度か色々試してるけど、0～1000をボーダー無しにした方が精度が高いモデルが出る感じ。上記のボーダーのみ0に変えた学習でNDCG@1=0.7837 NDCG@3=0.7878だと

それでもまだ精度が足りないorz これ、ここから更に伸ばすのは辛いのかな? これまでで、指数的には最高でも検証は最高ではないんだよね。

まだまだなのは変わらないけど、微妙な精度アップ。まあ、基本的に@3までが馬券に絡む精度指数なので気にしてます。今回@1が下がったものの、@3がアップ。なので多分トータルでの回収率が上がった要因なんだと思う。にしても、こりゃ難解だわ^^;

このモデル20MBなんですが、他の処理諸々した後ではOOM。さらだを一旦終了して再度起動して検証したら出来た。つまり、少しダイエットが必要。更に、ボーダー0にしたからなのか微妙にワイド以降の馬券の的中率が微減。

大事な事を忘れてた

モデルの指数は書いてるけど、どう設定してそれが得られたか書いてないので更に攻めるにしてもどんな設定試してたのか覚えてないorz まあ、イテレーション数5,000なのはモデルのファイル名で分かるけど、それ以外は全く不明ではあるが、それでもまあ、葉255、率は0.01～0.02の間を攻めてたと思うし、分割数は63辺りをやってたかと思うので、今晩も残業後だけど少し試そうかと、イテレーション数5,000、葉271、率0.01、分割数47、葉の最小50、ボーダー500でNDCG@1=0.7817 NDCG@3=0.7861 NDCG@5=0.7993 NDCG@10=0.8533とちょっと詳しく書いてみた。これはログに

これも微妙だ^^; 葉255に戻して率0.008、分割数63に戻す。NDCG@1=0.7813 NDCG@3=0.7853 NDCG@5=0.7986 NDCG@10=0.8530と全てダウンでダメダメなのは承知なんだが、何故こんな選択してみたかは、実は多分メモリギリギリなのが分かってるからで、案の定、連続で検証しようとするとOOMです。一旦アプリ閉じて再起動すれば検証出来てるけど、それは好ましい事じゃないんだよね。もっと軽いモデルで精度を上げなきゃと思うから多分新たな特徴量を検討しなきゃダメかも。

Out of Memory回避

以前からJV-Linkの32bit縛りに悩まされていたのは、せっかく出た高評価のモデルも予測として32bitアプリでロードするとOut of Memory(OOM)となり悔しい思いをしてきました。その為に一時はさらだ64も作成して、確かに64bit環境では問題なくモデルが使える事も確認してます。ただ、64bit環境で予測しても、リアルタイムでオッズ等が取れないもどかしさとかで、最近は一旦さらだ64は凍結し、さらだでの高精度狙えるモデルを色々と試してたどり着いたランキング学習がOOMで使えないのをGeminiに相談すると、32bitアプリはデフォルトでは最大2GBの壁となっているのを

<PropertyGroup>
  ...
  <LargeAddressAware>true</LargeAddressAware>
</PropertyGroup>

をプロジェクトに追加すれば最大4GBに出来ると教えてもらい試したら、それまでOOMで検証不能だったモデルも可能に! NDCG@1=0.7803 NDCG@3=0.7847のモデル(26.9MB)は

第67宝塚記念

ランキング学習があと少し精度アップさせたいのでもう少しと思いやってた所、ちょっと大掛かりな変更が必要になり時間が掛かってます。焦っても仕方ないので地道に進めてます。ざっくりな話として単勝27%複勝58%程度までは来てるので目標に届くと嬉しい。

ちょっとそんなので疲れたりしててあまり予想は乗り気じゃないが、グランプリだし自力予想してみました。

穴しか狙わないので(笑)

学習モデルにばかり時間取られて他のバグ潰しとかが若干滞ってます^^; 更にそもそも相対タイムも中途半端な感じなってしまったのは辛いですが、ある程度の成果は出ているかと思うので精度が更に期待出来るランキングに最善尽くしてみます。

しっかりとランキング学習

ここまでは、ざっくりと学習が動けばって感じの学習でした。これまでの回帰学習では当たり前のカテゴリ変数の扱いなんかを考慮してみた。イテレーション数3,000、葉255、率0.015、分割数127、葉の最小50、ボーダー500でNDCG@1=0.7789 NDCG@3=.7843となり

これはダメな修正だったorz 元に戻してイテレーション数5,000、葉255、率0.01、分割数127、葉の最小50、ボーダー500でNDCG@1=0.7795 NDCG@3=0.7845でOOM! 分割数63にするとNDCG@1=0.7805 NDCG@3=0.7847とかになるけど、やはりOOM。イテレーション数3,000に落とせばNDCG@1=0.7787 NDCG@3=0.7840で

まあ、これもJV-Linkの32bit縛りの宿命だな。

ちょっと勘違いとかもあり、それらを修正してイテレーション数3,000、葉255、率0.018、分割数63、葉の最小50、ボーダー500でNDCG@1=0.7778 NDCG@3=0.7836となりOOMって最悪です。

少し精度が上がった。しかし、何が良いって、まあ、相対タイムよりは確実に精度は上で、これ、学習時間が非常に短い。AutoMLでは何時間も学習させてたけど、イテレーション数10,000とかでも30分掛からない。ただ、AutoMLではモニター機能があるので学習中のログが表示出来るけど、ランキング学習ではひたすら待つ(笑)

学習時のオプションを追加してイテレーション5,000、葉255、率0.015でNDCG@1=0.7824 NDCG@3=0.7868のモデルは残念ながらOOM(Out of Memory)。イテレーション数3,500、葉175、率0.01でNDCG@1=0.7812 NDCG@3=0.7862のモデルは

当然ながら下げてる感じだけど、微妙な変化で単勝27.35%や枠連、馬連、ワイド、三連複は微増だけど回収率が下がってる。更に評価部を変えてみた所、NDCG@1=0.7789 NDCG@3=0.7843となり、

これでは逆効果なのでボーダー(600)変えてNDCG@1=0.7774 NDCG@3=0.7819はもっとダメかな?

それでも検証的にはそんなに悪くなった訳じゃない。ボーダー(550)にするとNDCG@1=0.7782 NDCG@3=0.7829で
