Pašuzraudzības teikumu iegulšanas

Pašuzraudzības teikumu iegulšanas apmāca neironu enkoderi, lai kartētu teikumus blīvā vektoru telpā, neprasot manuāli marķētus pārus. Automātiski konstruējot pozitīvus piemērus — piemēram, divreiz izlaižot to pašu teikumu caur izkrišanas (dropout) mehānismu — un izmantojot kontrastīvus mērķus, modelis apgūst semantiski bagātus attēlojumus, kas labi pārnesami uz līdzības, izguves un klasifikācijas uzdevumiem.
