ShokoPiece Tokenization
WordPiece ndiyo subword tokenization algorithm inopa simba BERT uye akawanda Google modhi, kupatsanura mazwi kuita zvidimbu zvinogona kushandiswazve kuitira kuti modhi igone kubata chero chinyorwa chine mazwi akasarudzika.
Pfupiso
It is why a model that has never seen 'unhappiness' can still understand it by reading 'un', '##happy', and '##ness'.
Kudzika Kwakadzika
WordPiece inovaka mazwi ezvikamu zviduku pane mazwi akazara kana mavara mamwechete. Kutanga kubva kune ega mavara, inosanganisa nemakaro maviri ezviratidzo izvo zvakanyanya kuwedzera mukana weiyo corpus yekudzidzira, ichidzokorora kusvika yasvika pachiyero chezwi rezwi (BERT inoshandisa anenge 30,000 tokens). Pakufungidzira, inoisa chiratidzo chemakaro kubva kuruboshwe kuenda-kurudyi, ichienderana nekazwi kadiki kakareba mudura remazwi, yozoenderera mberi neinosara. Zvidimbu zvekuenderera mberi mukati mezwi zvakaiswa chiratidzo che'##', saka 'kutamba' kunova 'kutamba' + '##ing'. Izvi zvinogadzirisa dambudziko rekunze-kwe-mazwi: mazwi asingawanzo kana asingaoneki anongoora kuita zvidimbu zvinozivikanwa, kusvika kune imwechete mavara kana zvichidikanwa, nepo mazwi akajairika anogara sechiratidzo chimwe chete chekushanda.
Technical Insight
WordPiece inosiyana neByte-Pair Encoding mune yayo yekubatanidza chiyero. BPE inobatanidza iyo inowanzoitika padyo peya; WordPiece inobatanidza mbiri iyo inokwidziridza kudzidziswa-data mukana, zvingangoita kusarudza vaviri vane frequency yekubatana inodarika chigadzirwa chezvikamu zvayo. Iyo '##' mucherechedzo inosiyanisa mazwi-ekutanga zvidimbu kubva mukuenderera mberi, ichirega iyo tokenizer ivakezve miganho yezwi zvisina tsarukano kana ichidhinda kudzoka kune zvinyorwa.
Strategic Impact
Kumhanya uye chiyero
Mutauro workflows inogona kufamba nekukurumidza pasina kupira kuenderana.
Svika uye svika
Inopamhidzira kupinda mumitauro yese nemataera ekutaurirana.
Sarudzo dzakajeka
Zvikwata zvinogona kupedza nguva yakawanda pakutonga uku otomatiki ichibata kudzokorora.
Ramangwana reWordPiece Tokenization
Mitsva mitsva yemitauro mikuru iri kuramba ichifarira BPE (GPT mhuri) kana SentencePiece unigram modhi, iyo inodzivirira kudhirowa kwemutauro uye kubata chero Unicode inopinza. WordPiece inoramba iri hwaro muBERT-yakatorwa encoders ichiri kuisirwa zvakanyanya kutsvaga nekuisa. Tarisira kuenderera mberi kwekushandiswa mukugadzira NLP, padivi pekutsvaga mune tokenizer-isina byte uye mhando mhando dzinogona kupedzisira dzadzikisira kuvimba neakagadziriswa subword vocabularies zvachose.
Real-World Implementation
BERT inoisa zviratidzo zvekutsvaga mu Google Tsvaga, ichiparura mazwi asina kujairika kuita madiki kuti modhi ienderane nemapeji anoenderana.
Hugging Face's BertTokenizer inoshandisa WordPiece kushandura mavara akaomeswa kuita ma tokeni ID anopihwa kuBERT yekuongorora manzwiro uye kuzivikanwa nezita-sangano.
Mitauro yakawanda BERT inoshandisa mazwi akagovaniswa eWordPiece mumitauro 100+, kuita kuti zvidimbu zvishandiswe zvakare mumagwaro ane hukama.
DistilBERT uye kiriniki/biomedical BERT akasiyana nhaka yeWordPiece, inobata zvisingawanzo mazwi ekurapa senge 'pneumonoconiosis' nekuapatsanura kuita zvidimbu zvinozivikanwa.
Njodzi & Guardrails
Chokwadi chehuroyi chinogona kupinda chinyararire mishumo, kuyerera kwetsigiro, kana tsvakiridzo.
Kunzwa nekukasira kunogona kugadzira mhedzisiro isingaenderane pane zvikumbiro zvakafanana.
Sensitive text data inogona kuburitswa kana zvidhiraivho zvisina kusimba.
Implementation Roadmap
Tsanangura chimiro chekubuda, toni, uye mhando zviyero usati waburitsa.
Mhinduro dzepasi neakavimbika masosi pese pazvine basa.
Chengetedza ongororo yekuongorora yemunhu kune yakakwira-stake zvinobuda.
Tevera maitiro ekutadza uye dzidzisazve kukurudzira kana mafambiro ebasa nguva nenguva.

Subword Tokenization

What is WordPiece Tokenization?
WordPiece ndiyo subword tokenization algorithm inopa simba BERT uye akawanda Google modhi, kupatsanura mazwi kuita zvidimbu zvinogona kushandiswazve kuitira kuti modhi igone kubata chero chinyorwa chine mazwi akasarudzika. Ndosaka muenzaniso usina kumboona 'kusafara' uchikwanisa kuzvinzwisisa nekuverenga 'un', '##fara', uye '##ness'.
Chii chinonzi '##' prefix chinoratidza muWordPiece kubuda?
WordPiece inocherekedza subword kuenderera mberi ne'##', saka 'kutamba' kunova 'kutamba' + '##ing', ichirega decoder ivakezve miganhu yemazwi.
Anenge akakura sei izwi rezwi reWordPiece rinoshandiswa neBERT yekutanga?
BERT inoshandisa izwi reWordPiece rinoda kusvika 30,000 subword units, kuenzanisa kuvharwa nekukura kwetafura.
Ko WordPiece's merge criterion inosiyana sei neyakajairwa Byte-Pair Encoding?
BPE inosanganisa iyo inowanzoitika padhuze peya, nepo WordPiece ichibatanidza iyo mbiri iyo inonyanya kuwedzera corpus mukana, ichifarira vaviri vane frequency yekubatana inodarika chigadzirwa chezvikamu zvavo.
WordPiece inobata sei izwi risati ramboonekwa panguva yekudzidziswa?
Mazwi asingaonekwi anotsemurwa kuva akareba anoenderana nemazwi madiki, achidzokera kune imwechete mavara, ayo anogadzirisa dambudziko rekunze kwemazwi.
Panguva yekufungidzira, WordPiece inosarudza sei kupatsanura izwi?
WordPiece tokenizes nehukaro, inoenderana nerebesa remazwi rekupinda rinotanga pachinzvimbo chazvino, rozodzokorora pane yasara.
