Résumé
It prevents a single huge update from destabilizing or destroying a model, especially in recurrent and language models.

What is Gradient Clipping?
Benn kaaraange bu yomb te ñu bari diko jëfandikoo mooy tënk ni coppite gradient yu mag yi mëna am ci diiru tàggat yaram. Dafay tere benn yeesal bu rëy destabilise wala yàq benn model, rawatina ci model yu bari ak làkk.
Lan la dagg gradient clip-by-norm di njëkka am ci di wàññi yeesal bi?
Clip-by-norm dafay eskale gradient yépp ci benn scalar, suko defee ñu baña bàyyi yoon wi ñuy wàcci, fekk guddaayu jéego bi kese lañuy tënk.
Ci clip-by-norm ak threshold c, lan mooy xew su norm gradient bi g_norm weesee c?
Sudee norm bi dafa yaatu lool, gradient bu nekk dañu koy escale ci c / g_norm suko defee norm biy génn nekk tollu ci threshold c.
Ban jafe-jafe lañu jagleel gradient clipping ngir xeex?
Dagg dafay tënk magnitude u yeesali, di tere ci saasi jéego yu rëy, yu amul dal yi gradient yuy kalaate waral.
Lan moo wuutale clip-par-valeur ak clip-par-norme?

Lan moo waral dagg gradient daanaka universel ci tàggat modelu làkk yu yaatu?
Ci anam wu yaatu, ay dugal yu bariwul mën nañu defar ay gradient yu rëy; dagg norm global dafay tere spikes yii destabiliser daw bi.
