二乗のボーダー500

40回スタートしてまず出たのはNDCG@1=0.7768 NDCG@3=0.7826でリニアより落ちるのはリニアから変更可能にして試した時に経験してたので想定内ですが

初回としてはこんなものかなぁ。確かに曲線にする事で上位入賞に重み付け出来ているのかも。

今日は勤務先の定例会で外出なので帰宅後に残りをチェックします。良いものが出ればそれを添付して次期リリースします。変更は単純に前回追加した特徴量を無視して学習させる変更だけですが、これが致命的悪影響で単勝的中率で2～3%ダウンしてるので、今晩か明日朝にする予定です。

NDCG

ランキング学習になってNDCGって使ってますが、これ、Normalized Discounted Cumulative Gainなんだけど、@1は1着、@3は3着までって感じで@5は掲示板にのるって意味合いなんだと思ってます。で、まあ、基本@1が高い方が良いとは思うけど、自分の元々の馬券スタイルはワイドから三連系なんです。つまり、@3重視でモデルを見た方が良いのではって事です。

そうすると、ボーダー500で40回の中でNDCG@1=0.7825 NDCG@3=0.7862は

これは微妙に良くないか^^; もう1つは直前に上げたNDCG@1=0.7840 NDCG@3=0.7880で同じく微妙に良くない。

って事で、まずはボーダー500から攻めてみるかな。

ランキング学習に着順を予測させるのにその評価としてCustomGainsを使ってるんだけど、単純に例えば18頭立ての1着～18着に値を設定して学習させるのに1着が当然最大で18着が最低になる必要がある。最初は1着=18点～18着=1点的な単純なところから、これだと同じ1着でも、何頭立てかで差が出るので工夫始めて1着=100点～18着=0点的なに変え、現状はその10倍で、1着=1,000点にしたり、ボーダーで例えば、500にすると半分で、10着～18着は0点、1着～9着に1～1,000点を割り振る。更にこれを乗数で、1.0ならリニア、それ以上なら弧を描く感じにするって具合です。

昨夜から本日でイテレーション数3,000、葉271、率0.01、分割数47、葉の最小50、乗数1.0という条件で、ボーダーのみ0か500で40回学習させてみました。500では、NDCG@1=0.7831 NDCG@3=0.7859が

最後に追加した特徴量

なかなか伸び悩んでたので、最後に追加した特徴量

GroupZ_PrevRank1
GroupZ_PrevRank2
GroupZ_PrevRank3
GroupZ_PrevRaceAto3F1
GroupZ_PrevRaceAto3F2
GroupRank_HirachiShokin
GroupRank_ShogaiShokin

ちょっと下にあるモデルと比較する為にイテレーション数3,000にしてみると、NDCG@1=0.7808 NDCG@3=0.7854とまあ１発で出たものなのでもう少し良いものもでるとは思うが、

流石にちょっと落ちた感じはするもそこまで悪いとも言えないね。しかも、下のよりはいい感じなので、やはり最後に追加した特徴量がほぼ無意味だった訳だ。

っとやはり、ボーダー0にすると指数的にはかなり上がるけど、検証的にはそれ程でもないんだよね。イテレーション数が500低いとかなりダイエットが出来るので、この線で行ければとは思うけど、ダメかなぁ。3,000だと18MB、3,500だと20MBなんだけど^^;

Microsoft Rewards 30回目

前回5月16日なので、47日目ですが先月末の何時だったか貯まったので交換しようとすると在庫切れorz 今回はMicrosoft側の在庫不足で月が替わるのを待っての申請でした。今回もamazonの600円にしましたけどね。楽天も在庫切れだったけど、これ、単にMicrosoft Rewardsの利用者が増えての現象かもね。まあ、継続します。

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

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。

これをどうやってNDCG@1をこれまで最高だった0.7824超えや更に0.8以上に持っていくか。少しいじってNDCG@1=0.7778 NDCG@3=0.7970で

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。
