Imodeli Dynamic: Iintlobo, iimpawu. Le nkqubo dynamical

Yintoni na ke imodeli ezinamandla? Zama ukubona iimpawu zawo, kuba imizekelo yeenkqubo ezinjalo.

models yokuhlela

Kukho iimpawu ezithile ukwahlula iintlobo ezahlukeneyo imifuziselo olutshintshayo.

Kuxhomekeka zomzekelo nezigaba zikhona:

• Kwengqondo - kubonisa imbono engqondweni nto;
• ulwazi - okubonisa ukufumana iinkcukacha, kunye nokuchongwa kweepateni kunye nobudlelwane (inkcazo, ingcaciso);
• olusesikweni - ezibandakanya ubuchule zemathematika kunye nemithetho ezichaza kwaye akwazi iinkqubo nezinto zenyani;
• ingqiqo - wadala kwinqanaba olubonakalayo okanye ngomlomo ezinxulumene imodeli imbangela noshowo kwaye zisebenza.

ndlela ukusebenza

Iimpawu imifuziselo olutshintshayo ithathela ingqalelo indlela kusetyenziselwa ukuphumeza imodeli. Ukusebenzisa izinto eziphathekayo kwenzeka ukuzala zejometri esisiseko, onamandla, ngokwasemzimbeni, iimpawu kukwasetyenziswa yona into yokuba zihlalutywe. Njengoko Eyonanto ibalulekileyo ucinga embodiments emzimbeni leyo efana indalo le into ekhethiweyo ukuba Ukulinganisa.

A isakhiwo sethiyori kunokuba ungafezeka, ngokusekelwe ubhalo, imizobo, iziphaluka isimilo zezibalo.

Division of uhle zezibalo

Kukho ukwahlukana yabo uhlalutyo ebandakanya inkcazo zeepropati kunye nokuzalana kwazo imisebenzi yesicelo. izinketho Ukulinganisa olunxamnye nezifundo ezininzi, ingakumbi, iinkqubo kunye ubuchule ezichaza indlela yokusebenza inkqubo kwenkqubo zihlalutywe.

Division ukubonisa of ATHUNYIWEYO

Phantsi olu khetho kukho ukungcola iintlobo ezintathu ezingundoqo imifanekiso.

Heuristics ezi imifanekiso ezivelayo ngobungqola yabantu. Ukuze ufumane inkcazelo epheleleyo yokusebenzisa kwabo amazwi kweelwimi zemveli. Umzekelo, ulwazi nemodeli yomlomo inokunxulunyaniswa uhlobo. Ukuba uchaze ayenzelwanga isicelo amabinzana zezibalo okanye ngokusesikweni-ubhalo.

It is a umzekelo heuristic yeyona ndlela iphambili yokuphuma ngaphaya imibono eyayikhona iziganeko ezithile kunye nezimo.

Le modeli ngentshukumo ezifunekayo isanda yoyilo, xa kungekho inkcazelo epheleleyo malunga isenzeko zihlalutywe okanye into. Okulandelayo, utshintsho imodeli ngaphakathi embodiments ngqo kunye ezithile.

imifuziselo Full-isikali zizinto ezahlukeneyo, ebonakala ngu umzekelo epheleleyo le nkqubo yezinto. Umahluko ikhona kuphela ubungakanani kodwa umbandela osetyenzisiweyo ukudala umfuziselo ngokupheleleyo.

Umfuziselo enamandla ingavezwa ifomu zezibalo. Kule meko Kucingelwa ukusetyenziswa amabinzana ezisesikweni ubhalo. Ngokufanayo, uyakwazi ukuchaza nesenzeko ngokwasengqondweni, intlalo, ezoqoqosho kunye neenkqubo.

imifuziselo Mathematical ingqalelo engaxabisi kakhulu yaye ubhetyebhetye iinketho, apho ukwazi ukuqhuba eksperimenti "olunyulu" ngenxa ingxaki ethile. It is a imodeli enamandla zezibalo sisiseko ukusetyenziswa kweekhompyutha neteknoloji computer. Iziphumo ezithi ezifunyenwe ngethuba zomzekelo lweMathematika zithelekiswa kunye amanani afunyenwe umzekelo emzimbeni.

EsiPhakathi ongakhetha lwavuka

Nayiphi na inkqubo enamandla linokuchazwa njengabalamli embodiments. Ipatheni graphic umlinganiselo phakathi embodiments zemathematika kunye heuristic. imifuziselo ezinjalo ingavezwa imifanekiso iigrafu, imizobo, imizobo, iigrafu.

iinguqulelo Analog zinika ithuba lokwenza uphando le into efanayo, okanye amabinzana zezibalo ngokudala into analog.

Inkqubo dynamical ikhethiwe kuxhomekeka kubume kunye nemali ulwazi malunga nayo, kwakunye ikhono umhlalutyi.

Umfuziselo static kuyinto ulwazi cut eyeyomzuzwana ngumkhuba bafunda okanye into leyo yakhiwe kangangexesha elithile. Yakha umfuziselo amaxwebhu accounting, ucinga ilahleko yenyanga okanye inzuzo.

Xa usebenzisa imodeli eguquguqukayo bangahlaziya iinguqu ezithi zenzeke kweli into kangangexesha elithile.

Amanqaku iinkqubo zolwazi

njani usebenzisa imifanekiso ezinamandla? Imizekelo yezi ntlobo - mali, ethabathe iminyaka embalwa, leyo ingasetyenziswa ukuqikelela yenzuzo yenkampani.

Phakathi iintlobo ezithandwayo iimodeli ulwazi kusetyenziswa iintlobo ezintathu: ukwakhiwa imodeli, a 'ibhokisi elimnyama "lobeko noshowo.

"Ibhokisi Black" umnxeba nkqubo, nto leyo into yonke, ezithatyathwe ihlabathi ngaphandle. Engqongileyo kunye neenkqubo anxulumene omnye komnye ngokutshintshiselana iziphumo kunye nezimvo. Imizekelo yeenkqubo eguquguqukayo olunjalo kuthathelwa ingqalelo i esiphilayo.

"Ibhokisi Black" umfuziselo ngumbonisi elula inkqubo ethile apho kungekho lwazi malunga umxholo lwasekhaya, kuphela output nee-input nonxibelelwano kunye nokusingqongileyo lwangaphandle. Imida phakathi okusingqongileyo kunye enjalo inkqubo ngesimo. Kusetyenziswe imodeli efanayo kwiimeko apho kungekho lwazi malunga nokuqulethwe yangaphakathi nkqubo. Umzekelo, imiyalelo zokusetyenziswa kumatshini wokuhlamba, i tape iqulethe inkcazelo eneenkcukacha zo xhulumaniso, ukusebenza hlengahlengiso ke, ngenxa usebenzisa isixhobo. Olu lwazi kwanele ukuba umsebenzisi-avareji, kodwa akwanelanga ukuba inkosi umsebenzi wazo eso sixhobo.

Umzekelo inkqubo olutshintshayo olunjalo kuthathwa njengento uhlalutyo lweengxelo accounting.

isiphelo

Kukho iinketho ezininzi inkcazelo iinkqubo olutshintshayo. Ukwenzela ukulawula ngempumelelo inkqubo kubalulekile ukuba zilinganisa nokuhlalutya imeko nkqubo. Ukukhethwa inkcazelo ethile kuxhomekeke ekufumanekeni kwenkcazelo lokuqala, ukukwazi ukufumana iinkcukacha ezongezelelweyo malunga nenkqubo, ithuba wophuhliso lwawo, iinjongo yokuqala Ukulinganisa.

Ukukhethwa imodeli osemqoka olutshintshatshintshayo umiselwa inkqubo efundwayo. Ukuba isayensi njengoko njongo iphambili yale Ukulinganisa na amathuba isifundo oluneenkcukacha kakuhle inkqubo, ubuchwepheshe lwenzelwe ukufumana uhlobo ngokupheleleyo yokulawula ukusebenza esixhobo, etyhila iilahleko ezincinci. Iinkqubo Dynamical zibandakanya ukuba sisebenzise iisimboli zezibalo, abalinganiswa, imithetho ukufumana iziphumo oluthembekileyo.
