Kuwedzera-Nguva Yekuedza
Test-time augmentation (TTA) inomhanyisa modhi yakadzidziswa pane akati wandei akachinjirwa mavhezheni eiyo yakafanana yekuisa uye mavhareji ekufungidzira.

Pfupiso
Iyo iri nyore, yekudzidzira-yemahara trick iyo inowanzo svina kunze mashoma ekuwedzera mapoinzi echokwadi uye inoita kuti fungidziro dziwedzere kusimba.
Kudzika Kwakadzika
Yedzero-nguva yekuwedzera inotora imwe chete inopinza, inogadzira akawanda akashandurwa makopi (mafiripi, zvirimwa, kutenderedzwa, mavara ekuchinja, kana akayera shanduro), inomhanyisa imwe neimwe kuburikidza neiyo yakafanana modhi yakagadziriswa, yozobatanidza zvinobuda - kazhinji neavhareji yezvingabvira kana marogi. Iyo intuition: imwe neimwe yekuwedzera inofumura modhi kune maonero akasiyana zvishoma, uye zvikanganiso pamaonero ega ega zvinowanzodzima kana zvabatanidzwa, senge diki ensemble yakavakwa kubva kune imwe network. Nehutsinye, TTA haidi kudzidziswazve uye hapana mamwe mavara; inongodhura yakawanda komputa pakufungidzira nekuti modhi inomhanyisa N nguva pamuenzaniso. Iyo inonyanya kufarirwa muchiratidzo chekombuta (kunyanya makwikwi eKaggle uye kufungidzira kwekurapa) asi zvakare inowanikwa muodhiyo uye zvinyorwa. Iwo mawedzero anofanirwa kuchengetedza iyo label - kupuruzira chipfuva X-ray zvakanaka, asi kupenengura dhijiti '6' kuita '9' hazvisi.
Kuitwa muNyika yeChokwadi
Avhareji yekufungidzira pamusoro peyakachinjika flips uye zvirimwa zvakawanda zvemufananidzo kuti uwedzere ImageNet kurongedza kurongeka pakufungidzira.
Kutenderedza kutenderedza/kuchinjika uye avhareji yemasiki muchikamu chemifananidzo yezvokurapa (semuenzaniso, bundu kana miganhu yenhengo) yetsanangudzo dzakatsiga.
Kaggle vakwikwidzi vanoshandisa gumi-zvirimwa kana akawanda-zvikero TTA kuti vawane chikamu chezana muzana pabhodhi rekutungamira pasina kudzidziswazve.
Kumhanyisa mataurirwo ekutaura kana maodhiyo ezvikamu zvakachinjika-nguva zvishoma kana kuti-zvinonetsa uye kubatanidza zvinobuda kune mamwe mavara akatsiga.
Ramangwana reKuedza-Nguva Kuwedzera
Tsvagiridzo iri kuenda kune yakadzidza uye inochinja TTA, uko diki mutemo unotora izvo zvekuwedzera zvinobatsira kune yega yega yekuisa pachinzvimbo chekushandisa yakagadziriswa seti. 'Kukara' uye kusiyanisa kutsvaga kweTTA-policy, pamwe nekusavimbika-kuremerwa avhareji iyo inovimba maonero ane chivimbo zvakanyanya, inzvimbo dzinoshanda. Tarisira kuti TTA isanganise nekuyedza-nguva yekudzidziswa uye yekuzvitarisisa kugadzirisa, kuita kuti mamodheru akaiswa agadzirise kufambiswa kwekuchinja panhunzi uchichengeta chivakwa chinokwezva chekusadzidzirazve.
Kuzvishandisa
Nei zvichikosha
- Mutengo uye bhajeti. Zvisarudzo zvezvivakwa zvinotyaira kuita uye mutengo wekushandisa kwemakore.
- Sarudzo dzakajeka. Dzidzo yehunyanzvi inobatsira zvikwata kusarudza murwi wakakodzera, kwete iwo mutsva chete.
- Kudzora kwemhando yepamusoro. Sarudzo dzeinjiniya dziri nani dzinoderedza zviitiko zvekuvimbika mukugadzira.
Chenjera
- Kugadzirisa imwe bhenji kunogona kuvanza yakafara system kushaya simba.
- Infrastructure uye mari yekugadzirisa inowanzotarisirwa pasi.
- Chengetedzo uye kucherechedzwa mapundu anogona kukura sezvo masisitimu anowedzera kuoma.
Matanho anotevera
- Tsanangura latency, mhando, uye mutengo zvinangwa usati waitwa.
- Benchmark pasi pechokwadi mutoro uye data mamiriro.
- Chishandiso chekutarisa zvikanganiso, kudonha, uye mushandisi maitiro.
- Gadzirira nzira dzekudzosera kumashure uye dzezviitiko usati wawedzera.

Chii chinonzi Test-Time Augmentation?
Test-time augmentation (TTA) inomhanyisa modhi yakadzidziswa pane akati wandei akachinjirwa mavhezheni eiyo yakafanana yekuisa uye mavhareji ekufungidzira. Iyo iri nyore, yekudzidzira-yemahara trick iyo inowanzo svina kunze mashoma ekuwedzera mapoinzi echokwadi uye inoita kuti fungidziro dziwedzere kusimba.
Panguva yekufungidzira, bvunzo-nguva yekuwedzera inoitei nekuisa kamwe chete?
TTA inodyisa akawanda augmented mavhezheni eimwe yekuisa kuburikidza neiyo imwechete yakadzidziswa modhi uye inounganidza fungidziro, pasina kudzidziswazve kunobatanidzwa.
When can pooling predictions from transformed views reduce prediction variance?
The ensemble intuition depends on useful, label-preserving views whose errors are not perfectly correlated.
Ndeipi mari huru yekushandisa TTA?
Nekuti pese pese panopfuudzwa nenetiweki N nguva, fungidziro inova ingangoita N nguva dzinodhura.
Ndeipi sarudzo yekuwedzera inogona KUKURUDZA dhijitari classifier?
Augmentations inofanira kuchengetedza iyo yechokwadi label; kupenengura mamwe madijiti anochinja hunhu hwawo uye zvinounza rusaruro.
Muchikamu, ndeipi nhanho yekuwedzera inodiwa usati waenzanisa zvabuda zveTTA?
Geometric augmentations inofambisa mapixels, saka imwe neimwe inobuda mask inofanira kuchinjwa kudzokera kune yekutanga coordination furemu isati yabatana.
