vim peb muaj ntau txheej thiab ntau nodes rau txheej hauv a neural network ? Peb xav tau tsawg kawg yog ib qho zais txheej nrog ib qho tsis-linear ua kom muaj peev xwm kawm cov haujlwm tsis-linear. Feem ntau, ib tug xav txog txhua tus txheej raws li qib abstraction. Li no koj tso cai rau tus qauv kom haum ntau txoj haujlwm.

Kuj tseem yuav paub yog, vim li cas siv ntau txheej hauv lub neural network?

A neural network siv cov kev ua haujlwm tsis-linear ntawm txhua qhov txheej . Ob txheej txhais tau hais tias tsis yog-linear muaj nuj nqi ntawm ib qho kev sib xyaw ua ke ntawm cov haujlwm tsis-linear ntawm cov kab sib txuas ntawm cov khoom siv. Qhov thib ob yog nplua nuj ntau dua li thawj tus. Li no qhov txawv ntawm kev ua tau zoo.

Tsis tas li ntawd, ntau txheej neural network yog dab tsi? Multilayer perceptron (MLP) yog ib chav kawm ntawm feedforward dag neural network (ANN). Ib qho MLP muaj tsawg kawg yog peb txheej ntawm cov nodes: ib qho kev tawm tswv yim txheej , ib zais txheej thiab tso zis txheej . Tsuas yog rau cov nodes input, txhua qhov node yog a neuron uas siv lub nonlinear activation muaj nuj nqi.

Hais txog qhov no, vim li cas neural networks muaj txheej txheej?

Neural networks (zoo li) xav tau ntau txheej txhawm rau kawm kom paub ntau ntxiv thiab kev sib raug zoo ntawm kev sib raug zoo hauv cov ntaub ntawv thiab yuav ua li cas cov yam ntxwv cuam tshuam nrog ib leeg ntawm qib tsis-linear.

Yuav tsum muaj pes tsawg txheej txheej neural network?

Txawm li cas los xij, neural networks nrog ob zais txheej tuaj yeem sawv cev ua haujlwm nrog txhua hom duab. Tam sim no tsis muaj laj thawj theoretical siv neural networks nrog ntau tshaj ob qhov zais txheej . Qhov tseeb, rau ntau cov teeb meem tswv yim, tsis muaj laj thawj siv ntau tshaj ib qho zais txheej.
