Overview
Ruzivo rwekugadzira distillation runodzidzisa mudiki 'mudzidzi' modhi kutevedzera hombe, yakarurama 'mudzidzisi' modhi. Izvo zvine basa nekuti inodhiza mamodheru ane simba saka anomhanya zvakachipa pamafoni nemaseva uku achichengeta kwakawanda kwechokwadi.
Knowledge Distillation inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero.
Deep Dive
Mamodheru makuru akarurama asi anononoka uye anodhura kuendesa. Ruzivo rwekunyungudutswa kweruzivo rwunotamisa kugona kwavo kuita compact modhi nekuita kuti mudzidzi adzidze kubva kune zvakaburitswa nemudzidzisi kwete kubva kune akaomesesa label. Muono wakakosha, kubva kuna Hinton nevaanoshanda navo, ndeyekuti kugovera kwemudzidzisi kuzere kunotakura 'ruzivo rwakasviba': kunyangwe kana ichifanotaura 'imbwa', zvingangoitika zve'mhumhi' maringe ne 'motokari' zvinoratidza kuti mudzidzisi anoona sei zvakafanana. Kupfavisa zvingangoitika izvi netembiricha zvinofumura chimiro ichocho, uye mudzidzi anodzidziswa kuchienzanisa, kazhinji padivi pemavara echokwadi. Mhedzisiro yacho idiki, inokurumidza modhi inogadzirisa zvirinani pane imwe yakadzidziswa pamalebula chete. DistilBERT uye TinyBERT mamodheru anozivikanwa emitauro.
Technical Insight
Kurasika kwekirasi kunobatanidza temu ye distillation (KL mutsauko pakati pezvingabvira zvakapfava zvemudzidzi nevadzidzisi) neyakajairwa muchinjiko-entropy pamavara echokwadi. Kupfava kunoshandisa tembiricha T mune softmax: yakakwirira T inodzikamisa kugovera saka madiki epakati-kirasi akafanana anove anodzidzika masaini; iyo distillation gradient inowanzo kuyerwa neT-squared. Misiyano inodarika zvinobuda: chimiro-chakavakirwa distillation machisi epakati akavanzika akaturikidzana, uye relation-based distillation inofananidza hukama pakati pemienzaniso.
Mastering Ruzivo Distillation
Ruzivo rwekugadzira distillation runodzidzisa mudiki 'mudzidzi' modhi kutevedzera hombe, yakarurama 'mudzidzisi' modhi. Izvo zvine basa nekuti inodhiza mamodheru ane simba saka anomhanya zvakachipa pamafoni nemaseva uku achichengeta kwakawanda kwechokwadi. Knowledge Distillation inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero. Kuvaka kunzwisisa kwakadzama, bata Ruzivo Distillation semuenzaniso wekushandisa, kwete chinhu chimwe chete: tsanangura zvinodikanwa, kujekesa fungidziro, uye patsanura izvo zvingaitwe nehurongwa hwakavimbika kubva kune zvichiri kuda kutonga kwenyanzvi.
Mukuita, zvikwata zvakasimba zvinoshandisa Knowledge Distillation inogadzirisa zvivakwa, data, uye sarudzo dzezvivakwa zvinopesana nekuvimbika uye mutengo. Ivo vanonyora zvakajeka maitiro ebudiriro, bvunzo vachipokana ne data rechokwadi uye mafambiro ebasa, uye iterate zvichibva pane zvakacherechedzwa maitiro ekutadza kwete kuhwina-nguva imwe chete yebhenji. Apa ndipo apo kunzwisisa kwe theoretical kunoshanduka kuve kugona kwakasimba pane chigadzirwa, mutemo, uye mashandiro.
Zvisarudzo zvezvivakwa zvinotyaira kuita uye mutengo wekushandisa kwemakore. Panguva imwecheteyo, Kukwirisa imwe bhenji kunogona kuvanza yakafara system kushaya simba. Nzira yakatsiga ndeyekubatanidza kukurumidza kuyedza nekutonga: mhanyisa vatyairi vendege, tora humbowo, buritsa matanda esarudzo, uye urambe uchivandudza chengetedzo semaitiro emuenzaniso, zvinotarisirwa nemushandisi, uye zvinodikanwa zvekutonga.
