What is Minimum Bayes Risk Decoding?
Ndozi opekempe Bayes Risk (MBR) na-ahọrọ mmepụta nke kacha yie ọtụtụ mpụta ndị ọzọ enwere ike, karịa otu nke nwere ike ime. Ọ na-ebuli elu maka metric dị mma nke ị na-eche n'ezie kama ịbụ nke adịchaghị.
Kedu ihe nhazi MBR na-ahọrọ kama otu usoro nwere ike ime?
MBR na-ahọpụta onye ndoro-ndoro ochichi nke na-ebuli uru a na-atụ anya ya (na-ebelata ihe ize ndụ) n'ihe gbasara ihe ngosi ndị ọzọ nwere ezi uche, ọ bụghị onye MAP.
Ebe ọ bụ na ezi nrụtụaka adịghị, kedu ihe MBR na-eji dị ka ntụaka pseudo?
MBR na-ejikọta nkesa ntụaka ahụ yana echiche nke ya atụpụtara, na-atụnyere onye ọ bụla n'ime ya na ọdọ mmiri ndị ọzọ.
