Pfupiso
Pamwe chete vanodzikamisa kudzidziswa kwekutanga uye kudzvanya kunze kuri nani kwekupedzisira, ndosaka inenge yega yega yemazuva ano shanduri yakadzidziswa nenzira iyi.
Kudzika Kwakadzika
Kana kudzidziswa kunotanga, uremu hwemodhini husina kurongeka uye magradients anogona kuve akakura, saka kusvetuka akananga kuchiyero chikuru chekudzidza kazhinji kunokonzeresa kurasikirwa kana kusiyana - kunyanya neadaptive optimizers saAdam, ane fungidziro yekusiyana isingavimbike mumatanho ekutanga. Warmup inogadzirisa izvi nekuwedzera mutsara chiyero pamusoro pemazana mashoma kusvika kuzviuru zvishoma matanho. Kana modhi yave patsoka yakagadzikana, cosine annealing inotora, ichiora mwero se 0.5 * (1 + cos(pi * t / T)) wepamusoro wayo. Iyo cosine chimiro inochengeta mwero wakakwira nekukurumidza kuti ufambire mberi nekukurumidza, wobva warerutswa zvishoma nezvishoma kuitira kuti iyo optimizer igone kugadzikana mune yakanaka hushoma pane kubhuroka ichiitenderedza.

Warmup-plus-cosine inoramba iri iyo yakasarudzika yemhando yemitauro mikuru, asi akasiyana ari kupararira. Warmup-stable-decay (WSD) inochengeta mwero wenguva dzose wobva waora zvakanyanya kumagumo, zvichiita kuti zvive nyore kuwedzera kumhanya pasina kudzoreredza kune hurefu hwakatarwa. Vatsvagiri vari kudzidzawo kuti nei warmup ichishanda - ichiibatanidza kune ruzha uye kurasikirwa-mamiriro ekutenderera - uye maturusi ari kuwedzera auto-tune warmup kureba uye peak rate, kuderedza bhuku rekuedza-uye-kukanganisa kuri kutonga nhasi.
