They matter for showing how to get strong accuracy with far fewer parameters, ideal for deployment.
Ime miri emi
Jasper (Nanị Ihe Nchọpụta Okwu Ọzọ), nke NVIDIA weputara na 2019, bụ netwọọdụ convolutional 1D miri emi, ruo ọkwa 54, nke na-esepụta njirimara mel-spectrogram na mkpụrụedemede na-eji mfu CTC. Ọ webatara njikọ dị nhịahụ ka gradients na-asọpụta nke ọma site na ngwugwu miri emi. QuartzNet, nke ewepụtara n'otu afọ ahụ, debere usoro mgbochi Jasper mana dochie convolutions ọkọlọtọ na ngbanwe nke ọwa oge, na-ekewa nzacha nke ọ bụla n'ime ntụgharị oge omimi miri emi yana usoro ịgwakọta ọwa dabara adaba. Nrụpụta a wepụrụ paramita sitere na ihe dị ka nde 333 nke Jasper gbadara nde 19 ka ọ dabara na Librispeech.

What is Jasper and QuartzNet ASR?
Jasper na QuartzNet bụ NVIDIA's end-na-end convolutional convolutional speech model, na QuartzNet bụ obere obere, nhazigharị nke ọma nke Jasper. Ha dị mkpa maka igosi otu esi enweta izi ezi siri ike na parampat dị ole na ole, nke dị mma maka ibugharị.
Kedu isi ihe ọhụrụ na-ahapụ QuartzNet jiri parampat dị obere karịa Jasper?
QuartzNet dochie convolutions ọkọlọtọ na ọwa oge nkewa, na-egbutu ọnụ ọgụgụ oke ma na-echekwa izi ezi.
Ihe dị ka nkeji ole QuartzNet nwere atụnyere nde ~333 nke Jasper?
QuartzNet na-agbada ruo ihe dị ka nde 19, ihe dị ka mbelata 17x, ebe ọ dabara na izi ezi Librispeech Jasper.
