ボーダーの癖?

ボーダーを0にする時と500にする時でNDCGがボーダー0の時は高く、ボーダー500の時には低くなるのは、何度も学習させてきて分かってます。今朝出勤前に

こちらは随分と頑張ってる感じがしますが、でも、もう一押し欲しいんだよね。今回、まあ、ボーダー0は一区切りして、ボーダー500を攻める予定なんだけど、流石に葉を399までしたし、葉の最初も80にあげてるので、モデルサイズが13MB超えにはなってます。自分の感覚的にはやはりボーダー500の方が検証結果的には上かな?

モデルサイズ的にはまたもう少し肥大化しても耐えられそうなので、攻めようかと思うけど、まあ、正攻法的には多分葉を増やすんだと思うので、ここは葉を415にして20回試してみます。20回なら寝る前に条件替えて40回とかも行けるしね。

目指すべきもの

サボってはないですよ(笑) 今週末も学習させながらコーディングもしてます。まあ、AIとじゃれてるってのもあるが^^; 先日書いたEarlyStoppingRoundの現状バージョンでは実装不可ってのをAIではなく人間が挑んだらどうかって事で今週末やってるんだけど、まあ、結局AIのサポートも受けないと出来ないので「じゃれてる」って事になる(笑) これ、実際にはそれ程重要な事でもない気もしてるが、もし実装できればそれはそれでね。でも、結局は諦める事に^^;

多分、実装するのに必要なスキルがGeminiにもCopilotにも、更には自分にも無いのが原因な気もするし、そもそもML.NET側のバグかもしれませんが、ここはそれ以上の追及はしない事にしました。

で、ランキング学習ですが、モデルのダイエットも兼ねてイテレーション数を減らしました。これね、EarlyStoppingRoundが実装出来れば、また違った感じに出来たかもですが、実装出来なかったものを期待しても仕方がないので人力で変更(笑)

AIに騙される

ここ数日はGeminiに騙されて無駄な時間を費やし、昨夜、CopilotにGeminiに騙されたけどお前は出来る?って訊くと自信満々に言うので、仕事終えて帰宅して、ではお願いって感じでコード提示してもらうと、まあ、想定内でGeminiとは大差ない。で、まあ、問い詰めるとサラッと謝罪する始末(笑)

じゃあ、ああっ、その過程でやってたのはEarlyStoppingRoundの導入なんだが、結局どちらもこれの実装はまだ完璧じゃないから利用出来ないって事でした。そこで、ここまでの最適パラメーターを見せてどうすれば良いかを尋ねると

既に手詰まり一歩手前

ここまでパラメーターを色々と変えて試すもこれといったものが得られない。先日ゲリラ雷雨で中断してたパターンを昨晩50回やったけど、結局あの2回目超えるものは出なかった。これ、単に運が悪いだけかもですが、まあ、そんなものです。次の一手は乗数をチョイ上げてみた。40回でスタート。

イテレーション数2,000ではなのか、モデルサイズ自体はまだ15MB程度なのでもう少し葉を増やすべきかなぁ。これ、40回やるのに6時間程掛かる。

モデルのサイズ

昨夜試した学習はイテレーション数2,000にしました。ここまで採用したのは3,000でしたが、モデルサイズが16MBでした。葉の数増やして細かくフィットされてみる為にイテレーション数を減らし葉を増やす。どの程度影響してるか把握はしてないけど分割数も減らす。で、昨夜は率は0.015でした。これだと13MB。

で、今試しているのは

NumberOfLeaves: 335
NumberOfIterations: 2000
LearningRate: 0.01
MaximumBinCountPerFeature: 31
MinimumExampleCountPerLeaf: 50
CustomGains: 0～500 = 0点, 501～1000は1.8乗に0～1000点

なんですが、葉をさらに増やして率は0.01に。これだとほぼ15MBに近くなります。15回目でNDCG@1=0.7792 NDCG@3=0.7831

まあまだのこり20回以上あるので良いものが出る事を期待したいです。ワイドが頑張ってる感じがします。なんか工夫次第で行ける範囲なきもする。

期待値で絞って攻めるのもありかも。これ、クラス別を作りこむの忘れてたのでこの後追加してみます。
