Pfupiso
Izvo zvine basa nekuti ma activation mumamodhi mahombe ane akawandisa kunze ayo anowanzo kukanganisa yakaderera-chaiyo math, uye SmoothQuant inovabata.
Kudzika Kwakadzika
Paunoderedza modhi kubva pa16-bit inoyangarara kuenda ku8-bit integers, huremu hunodzvanya nyore asi activations inonetsa: mamwe machanera anotakura zvakakosha 10 kusvika 100 akakura kupfuura mamwe, uye kuamanikidza kupinda coarse integer grid kunoparadza kurongeka. SmoothQuant, yakaunzwa naXiao et al. muna 2022, inoona kuti huremu hwakatsetseka uye huri nyore kuverengera uku activation iri spiky. Saka inotamisa kuoma kwemasvomhu: inopatsanura migero yekugonesa nechiyero che-per-channel uye inowanza huremu hunoenderana nechiyero chimwe chete. Iwo maviri mashandiro akadzima, achisiya iyo modhi yekubuda isina kuchinjika, asi ikozvino ese matensor anogara muhushamwari. Mhedzisiro ndeyeW8A8 (8-bit uremu uye activation) inference ine padyo-zero kurasika kwekurasika uye ingangoita 2x kumhanya uye ndangariro kuchengetedza.

Ramangwana reSmoothQuant uye Activation Quantization
SmoothQuant yakasimbisa kuti activation outliers inotamisa pane isingadzivisike, uye iyo pfungwa ikozvino inosimbisa kugadzirwa INT8 uye FP8 kushanda. Tarisira kutsvedzerera kusanganisirwa nezvirongwa zvakanakisa senge-per-group quantization, kudzidza kuyera, uye 4-bit activation research (e.g. outlier-aware ways). Sezvo FP8 Hardware (Hopper, Blackwell) inokura, kutsetseka-maitiro ekuyeresa acharamba achibikwa mucompiler uye inference-injini mapaipi kuitira kuti quantization igare yakasununguka.

Chii chinonzi SmoothQuant uye Activation Quantization?
SmoothQuant inzira inoita kuti zvikwanise kudzvanya mamodheru emitauro mikuru kusvika pa8-bit integers kune ese maremu uye ma activation pasina kudzidziswazve. Izvo zvine basa nekuti ma activation mumamodhi mahombe ane akawandisa kunze ayo anowanzo kukanganisa yakaderera-chaiyo math, uye SmoothQuant inovabata.
Nderipi dambudziko iro SmoothQuant rinonyatso gadzirisa mune yakaderera-chaiyo inference?
SmoothQuant inonangana nehukuru hwekunze hunoonekwa mune dzimwe activation chiteshi, izvo zvikasadaro zvinoparadza chokwadi kana activation ichiverengerwa ku8 bits.
SmoothQuant inoita sei kuti ma activation ave nyore kuverengera?
Iyo inopatsanura activation chiteshi nechikero che-per-channel uye inowanza huremu hunofananidzwa nechikero ichocho, saka chigadzirwa hachichinjiki asi ese matensor anova nyore kuyera.
Ko notation W8A8 inorevei?
W8A8 inoreva 8-bit quantization yezviremu zvese (W) uye activation (A), iyo hurumende SmoothQuant inogonesa nekurasikirwa kudiki kwechokwadi.
Sei kuyera kweSmoothQuant kuchiwedzera zvakanyanya pasina nguva yekumhanya?
Zviyero zvekutsvedzerera zvinopetwa muhuremu hwekare kana kuti fused op pamberi penguva, saka hapana imwe computation inoitika pakufungidzira.
Ndeipi basa rinoitwa nealpha hyperparameter muSmoothQuant?
Alpha (kazhinji 0.5) inoyera iyo inotsvedzerera chinhu, ichifunga kuti yakawanda sei yekuomerwa kweiyo quantization inobviswa kubva kune activation uye pahuremu.
