Variance yog qhov nruab nrab ntawm squared nrug ntawm txhua qhov taw tes mus rau qhov nruab nrab. … Ib qho teeb meem nrog qhov sib txawv yog qhov nws tsis muaj qhov ntsuas tib yam li cov ntaub ntawv qub Piv txwv li, cov ntaub ntawv qub uas muaj qhov ntev ntsuas hauv ko taw muaj qhov sib txawv ntsuas hauv square feet.
Yuav ua li cas ntsuas qhov sib txawv hauv?
qauv sib txawv yog qhia nyob rau hauv tib units raws li tus nqi qub (piv txwv li, feeb lossis meters). Variance qhia nyob rau hauv ntau qhov loj dua (piv txwv li, meters squared).
Puas yog qhov sib txawv ntawm qhov ntsuas?
Cov mis rau qhov sib txawv yog siv cov squares. Yog li ntawd, qhov sib txawv muaj qhov sib txawv dua li cov ntaub ntawv uas nws tau suavPiv txwv li, yog tias cov ntaub ntawv raug ntsuas hauv inches, qhov sib txawv yuav raug ntsuas hauv square inches. … Yog hais tias qhov tshwm sim ntawm ib qho kev ntsuas yog squared, ntxiv ^2 rau lub cim, piv txwv li. m^2.
Puas hloov pauv nrog cov units?
Effect of Change Units
Yog tias koj ntxiv qhov tsis tu ncua rau txhua tus nqi, qhov kev ncua deb ntawm qhov tseem ceeb tsis hloov. Raws li qhov tshwm sim, txhua qhov kev ntsuas ntawm qhov sib txawv (ntau, qhov sib txawv ntawm qhov sib txawv, tus qauv sib txawv, thiab qhov sib txawv) nyob twj ywm tib yam.
Yuav ua li cas rau cov qauv qauv sib txawv?
Tus qauv qauv sib txawv yog ntsuas hauv tib chav raws li cov ntaub ntawv qub. Ntawd yog, piv txwv li, yog tias cov ntaub ntawv nyob hauv ko taw, ces tus qauv sib txawv yuav qhia nyob rau hauv cov square feet thiab cov qauv qauv sib txawv hauv cov ko taw.

Vim li cas tsis muaj qhov piv txwv yooj yim muaj units?
Ib tus piv yog ib txwm sau siv tag nrho cov lej nkaus xwb, tsis muaj units, hauv nws daim ntawv yooj yim tshaj plaws. Cov lej hauv qhov sib piv yuav tsum tau sau siv tib lub units. Yog tsis yog lawv yuav tsum hloov mus rau tib units Tsis muaj teeb meem dab tsi yog siv rau kev hloov pauv .
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Qhov twg yog qhov piv txwv ntawm kev sib piv?
Adjectives nyob rau hauv daim ntawv sib piv piv ob tug neeg, qhov chaw, los yog yam. Piv txwv li, nyob rau hauv kab lus, 'John yog smarter, tab sis Bob siab dua, ' cov ntaub ntawv sib piv ntawm cov npe 'smart' (smarter) thiab 'siab' (siab) yog siv los ua.
Lub network twg muaj qhov sib txawv ntawm qhov sib txawv?
Convolutional neural networks ( CNN's) tuaj yeem siv los kawm cov yam ntxwv nrog rau kev faib cov ntaub ntawv nrog kev pab ntawm cov duab thav duab. Muaj ntau hom CNN's. Ib chav kawm ntawm CNN's yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov neural networks .
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
