Bog'liq qidiruv-tizimlari-algoritmlarining-tahlili Rasm. Qidiruv tizimlarining ishlash sxemasi.
Mashhur qidiruv tizimi algoritmlari
PageRank algoritmi: Ushbu algoritm Google tomonidan ishlab chiqilgan va sahifaga kiruvchi havolalar soniga qarab qidiruv natijalarini ustuvorlashtirish uchun mo’ljallangan. U sahifani boshqa sahifalarga nisbatan ahamiyatini aniqlash uchun sahifaga bo’lgan havolalar miqdori va sifatini o’lchaydi. PageRank ma’lum bir qidiruv so’rovida eng mos va maqbul saytlarni aniqlashga yordam beradi.
Umumiy holda, har qanday sahifa “𝓊” uchun PageRank qiymatini quyidagicha ifodalash mumkin:
ya’ni “𝓊” sahifasi uchun PageRank qiymati: Bu to’plamidagi har bir “𝓋” sahifaning PageRank qiymatini shu sahifadagi havolalarning L(𝓋) soniga bo’linadi va har bir bo’linma qo’shib chiqiladi.
TF-IDF algoritmi : Bu algoritm Term Frequency-Inverse Document Frequency so’zlarining qisqartmasidan ushbu nomga ega bo’lgan va berilgan so’rov bo’yicha hujjatning dolzarbligini aniqlash uchun ishlatiladi. U hujjatdagi atamaning chastotasini o’lchaydi va keyin ma’lum hujjatlar to’plamidagi atamaning ahamiyatini tortish uchun teskari hujjat chastotasidan foydalanadi. Ushbu algoritm ko’pincha veb-saytning ma’lum bir so’rov uchun mosligini o’lchash uchun ishlatiladi.
TF-IDF statistik o’lchovi ortidagi oddiy formulani ko’rib chiqaylik. Dastlab ba’zi belgilarni aniqlaymiz:
N - bizning ma’lumotlar to’plamimizdagi hujjatlar soni d - bizning ma’lumotlar to’plamimizdan berilgan hujjat D - barcha hujjatlar to’plami
w - hujjatdagi berilgan so’z
Birinchi qadamda hujjat chastotasi tf(w,d) hisoblanadi.
𝑡𝑓(𝑤, 𝑑) = 𝑙𝑜𝑔(1 + 𝑓(𝑤, 𝑑))
|
2)
|
Bu yerda 𝒇(𝒘, 𝒅) - d hujjatidagi w so'zining chastotasi.
Ikkinchi qadamda teskari hujjat chastotasi hisoblanadi.
𝑁
𝑖𝑑𝑓(𝑤, 𝐷) = 𝑙𝑜𝑔 ( ( ))

Ma'lumotlar to'plamida N ta hujjat va f(w, D) butun ma'lumotlar to'plamidagi w so'zining chastotasi bilan bu raqam butun ma'lumotlar to'plamida so'zning ko'proq ko'rinishi bilan kamroq bo'ladi.
Yakuniy qadam TF-IDF ballini quyidagi formula bo'yicha hisoblanadi:
𝑡𝑓𝑖𝑑𝑓(𝑤, 𝑑, 𝐷) = 𝑡𝑓(𝑤, 𝑑) ∗ 𝑖𝑑𝑓(𝑤, 𝐷)

Literature review - This Action Research Plan Aims To Explore Various Communicative Methods And Techniques Used By Teachers To Enhance Students' Speaking Skills In English As A Second Language. However, Students' Classroom Behavior In Asian Countries Is Often Hindered By Fear Of Errors And Mockery. The Plan Investigates Articles And Scientific Opinions To Address This Issue And Find Innovative Solutions.
Kurt and Desi Andriani conducted research on improving students' speaking skills using communicative games. Kurt's study found that using games improved students' confidence, participation, enthusiasm, and fluency. Desi Andriani and Hermawati Syarif's study found that debate games increased communication and cooperation among seventh-grade students, fostering socialization in teaching and learning. Both studies suggest that communicative games are effective in fostering cooperative activities and fostering positive relationships. Littlewood (1981) categorizes communicative activities into social contact and functional communication. A study using a pre-experimental design found that using communicative games improved students' English-speaking abilities. The results showed that these games increased motivation, interest, and confidence, making them a useful teaching tool for English teachers.

Bog'liq YULDOSHEVA SOnline, the conventional constraints of space and time disappear and there is a dizzyingly wide range of communicative possibilities. The impact of social media applications has triggered discussion of the “new communication democracy.” - The development of the Internet today is being shaped predominantly by instant, mobile communications. The mobile Internet is a fresh revolution. Comprehensive Internet connectivity via smartphones and tablets is leading to an increasingly mobile reality: we are not tied to any single specific device, and everything is in the cloud.
Traveling Otherworldly on Earth In Yellowstone, the wonders surrounding you are unlike anything else. Our first national park is a true marvel to behold; visiting Yellowstone is like stepping into another world. - Planning a Visit? For information about the park, visit the National Park Service website for Yellowstone National Park: Yellowstone National Park, America’s first National Park, offers truly unique experiences like spectacular hiking trails, beautiful views, Old Faithful, and geysers shooting water 100 feet into the air. Plan your visit with NPF’s resources.
When the first visitors to Yellowstone tried to report what they saw, news magazines responded, “Thank you, but we do not print fiction.” Peppered with colorful hot springs, mudpots, and breathtaking waterfalls, it is easy to understand how one might think it otherworldly. Nothing else on Earth is quite like Yellowstone—and there is something for everyone, from children to grandparents.

Solar-Wind Hybrid Power System Analysis Using Homer for
Duhok, Iraq
Abstract. The government of Iraq recently joined the Paris Climate Agreement, it has now begun to encourage the participation of small and large
consumers to generate electricity from renewable energy resources. This article analyses a hybrid solar-wind electrical system for Duhok city
northern part of Iraq to know the feasibility of this system compared to the local electrical network. Firstly, an access to solar and wind resources
have been ensured for Duhok. For evaluation and optimization study, both stand-alone (off-grid) and grid connecting (on-grid) systems taken into
consideration to be optimized. HOMER is a software application employed to perform the power and cost analysis based on wind speed, solar
irradiance and load profile. According to the numerous configurations. Simulation outcomes have been shown that the on-grid hybrid solar-wind
energy system at Duhok site is most cost-effective than off-grid design for the same load, also it is better cost efficient than Duhok residential power
grid, as our system cost unit COE is (0.0109 $\kWh) while Duhok residential electricity COE is 0.1$\kWh.

północnej części Iraku w mieście Duhok, aby poznać wykonalność tego systemu w porównaniu z lokalną siecią elektryczną. Po pierwsze
zapewniono Duhok dostęp do zasobów energii słonecznej i wiatrowej. Do oceny i badania optymalizacyjnego brane są pod uwagę zarówno systemy
autonomiczne (poza siecią), jak i systemy przyłączania do sieci (w sieci). HOMER to aplikacja służąca do przeprowadzania analizy mocy i kosztów
w oparciu o prędkość wiatru, nasłonecznienie i profil obciążenia. Według licznych konfiguracji. Wyniki symulacji wykazały, że hybrydowy system
energii słonecznej i wiatrowej w sieci w Duhok jest najbardziej opłacalny niż projekt poza siecią dla tego samego obciążenia, a także jest bardziej
opłacalny niż mieszkaniowa sieć energetyczna w Duhok, ponieważ koszt naszego systemu jednostka COE wynosi (0,0109 $\kWh), podczas gdy
wskaźnik COE energii elektrycznej w budynkach mieszkalnych Duhok wynosi 0,1 $\kWh. (

PART 2
Describe a person you know who likes to talk a lot.
- who is this person
- what he or she likes to talk about
- how you
feel talking to this person
This person I know
is my classmate and my friend, Bekmurod. Bekmurod loves talk
about his new job in the Tashkent. He works
at language centre, named
“Cambridge learning centre”. He also enjoys
talking about English with me, by the
way Bekmurod is my English teacher and I like to call him as a Master. He is the
smart of person who can strike up a conversation with just about anyone and keep
it going for years. When I talk to Bekmurod, I feel like
happy because he always
has something interesting to say. Sometimes, I feel like to
share my own stories
too, but Bekmurod is such a good speaker that I don’t mind listening to
his talk for

1- mavzu. Akademik yozuv va axborot. Axborot turlari
Nazariy ma’lumot.
Akademik yozuv
– bu qisqa va ishonchli ilmiy matn yordamida o‘z fikrini
bayon qilish hamda asoslay olish qobiliyati. Bu oliy ta’limda muvoffaqiyatli
bilim berishning hamda
keyingi ilmiy-
tadqiqot faoliyati, shuningdek
xalqaro
miqyosda
ham muhim aspektlaridan biri
hisoblanadi. Akademik yozuv yordamida
oxirgi o‘n
yilliklar ichida turli
mamlakatlar orasida ilmiy va ta’limiy
kommunikatsiya amalga oshirilib
kelinmoqda. Uning tamoyillariga butun
dunyodagi eng kompetentli
ilmiy nashrlar
redaktorlari amal qiladilar, shuning uchun hamma istalgan fan bo‘yicha ma’lum
bir yutuqlarga erishmoqchi bo‘lsa, bularni egallashi lozim.
Akademik yozuv – bu ilmiy ishlarni bayon qilish uslubi. U
ilmiy ishlarda
fikrlarni qisqa va tushunarli shaklda bayon qilish qobiliyatini aks ettiradi. Bu
uslubda quyidagilarni farqlash mumkin:
matnning tuzilishi va uni rasmiylashtirishga qo‘yiladigan talablarning
mavjudligi;
ilmiy va publitsistik bayon qilish uslubini qo‘llash;
dalillar keltirish va jumlalarni o‘zgartirib ifodalash;
havolalarni to‘g’ri joylash va adabiyotlar ro‘yxatini to‘g’ri shakllantirish
qobiliyati.
Akademik yozuv uchun shaxsiy fikrni bildirish emas, balki
keltirilgan
muammoga e’tiborni qaratish xarakterli (o‘ziga xos). Birinchi shaxs o‘rniga
uchinchi shaxsni qo‘llash, og’zaki nutqni, qisqartmalarni, iboralarni qo‘llamaslik
afzalroqdir. Boshqa uslublardan farqli o‘laroq, materialni yaxshi o‘zlashtirish
maqsadida bir so‘zni bir necha bor qaytarish mumkin, sinonimlarni
kamroq
ishlatish kerak.
Bayon qilishning akademik uslubi oliy ta’lim muassasalarida davlatlar o‘rtasida
ta’limiy va ilmiy aloqalarni olib borishda qo‘llaniladi. Uning yordamida
talabalar, aspirantlar va malakali olimlar doklad, kurs ishi yozadilar hamda o‘zga
davlatlarda ilmiy-tadqiqot faoliyatini olib boradilar.
Xalqaro ilmiy jurnallar redaktorlari bu uslub tamoyillariga tayanadilar, shuning
uchun ilm dunyosida muvoffaqiyatga erishmoqchi
7
bo‘lgan hamda chet ellarda ilmiy ishlarini chop etmoqchi bo‘lgan harbir olim bu
uslubni egallashi lozim.
Chet eldagi davlatlarda tadqiqotchilar uzoq yillardan beri
akademik yozuvdan
foydalanadilar. Bundan tashqari, ingliz tilida so‘zlashuvchi olimlar uning
rivojiga hissa qo‘shib kelmoqdalar. Bizning mamlakatimizda
akademik uslub
bo‘yicha bilimlar keng tarqalmagan, vaholanki
bu muammoning yеchimi bilan
bir qator olimlar – filologlar, lingvistlar, sotsiopsixologlar, axborot
texnologiyalari bo‘yicha mutaxassislar shug’ullanadilar.
1. How often do you make telephone calls? [Why/Why not?]

IELTS Speaking Part 1 Telephone and Mobile Phones Question and
Answers
1. How often do you make telephone calls? [Why/Why not?]
I rarely use my landline phone, but I use my cell phone constantly. I make
and receive phone calls on my mobile device, send and receive text
messages, and occasionally access the internet. On my phone, I frequently
play games while listening to my favorite music. I hardly ever go a day
without using it.
2. What was your first mobile phone?
In 2012, I purchased a Motorola phone as my first mobile phone. Because I
was a school student and had limited funds at the time, it was extremely
pricey. I took a part-time job to get the cash, which I used to purchase from
a mall. Fortunately, it turned out that buying the phone was a wise decision.
3. Who do you spend the most time talking to on the phone? [Why?]
That would be my mother, I think. She is quite close to me and becomes
concerned if I am absent for more than a few hours. When I am away from
home, she calls me a few times a day, and I can tell her almost anything.
She is the person I talk to on the phone or on my cell phone the most
because of these factors.
4. When do you think you’ll next make a telephone call? [Why?]
After I leave the exam room, I'll give my mother a call to let her know
everything is great and my test went really well. I'll give her a call because I
know she's anxious to hear from me and find out how well I did on the test.
5. Do you sometimes prefer to send a text message instead of
telephoning? [Why/Why not?]
Yes, there are occasions when texting someone makes more sense and is
more practical than contacting them. For instance, I would choose SMS
over phone calls if I were in a meeting or a crowded area. Additionally, I
would rather send a text message than call the intended recipient if I
needed to convey an address, a phone number, or an email address.
6. Can you describe the mobile phone that you are currently using?
I'm now using an iPhone. It had many fascinating features and apps while
being relatively pricey. The FACE ID lock system is really practical and the
screen response is flawless. It always works. In addition, the camera is
fantastic and does not have a delay, allowing me to constantly record
several moments.

«Facebook» tarixida ham har qanday saytlardagi kabi uzilishlar
sodir bo‘lib turadi. 2014 yilda bu kabi holat 2 marotaba bo‘lgan: 19
iyun va 1 avgustda.
Ijtimoiy tarmoqqa butun dunyodagi foydalanuvchilar kira olmay
qolgan. Bu kabi muammo boshqa servislarda — «Instagram»,
«Skype», «Tinder» ham yuzaga kelgan. Dasturchilar saytning
ishini qayta tiklash uchun ikki safar ham salkam bir soat vaqt
sarflashgan.
Bu esa ommaviy vahimani yuzga keltirgan. Los-Anjeles okrugi
sherifi o‘zining «Twitter»dagi sahifasi orqali odamlarni politsiyaga
qo‘ng‘iroq qilavermaslikka chaqirgan.
«Facebook»ning 2014 yildagi moliyaviy hisobotlarga ko‘ra, u bir yil
davomida 2,9 milliard dollar foyda ko‘rgan. Bu bir kunda 32
million dollar yoki bir soatda deyarli 1,5 million dollar deganidir.
Shunday ekan, 12:08 dan 12:27 gacha sodir bo‘lgan uzilishlar
vaqtida «Facebook» deyarli 427 ming dollar yo‘qotgan.
«FACEBOOK» BIR DAQIQADA 23 MING
DOLLAR ISHLAB TOPADI
XAYRIYA
2015 yil dekabr oyida Tsukerberg deyarli barcha
boyliklarini xayriya ishlariga bag'ishlashini e'lon
qildi. "Biz Facebook aktsiyalarimizning 99 foizini
beramiz-hozirda bu taxminan 45 milliard dollarni
tashkil etadi. "butun hayotimiz davomida bu
dunyoni keyingi avlod uchun yaxshilash uchun
ko'plab boshqalarni qo'shish uchun", deb yozgan
milliarder o'zining Facebook sahifasida[20].
2016 yil 21 sentabrda Mark Tsukerberg va uning
rafiqasi Priskilla Chan Chan Zuckerberg
Initiative[en] doirasida yangi loyiha Chan
Zuckerberg Science ishga tushirilganini e'lon
qilishdi. Loyiha turli kasalliklarga qarshi
kurashishga qaratilgan bo'lib, unga 10 yil ichida 3
milliard dollar sarflanadi.

odamda «ranglarni ko‘rish nuqsoni»ni paydo qiladi,
natijada uchta rang (yashil, sariq va qizil) birlashib

BOSHLIG‘IGA AYLANARDI
2012 yildagi intervyulardan birida Sukerbergdan «agarda «Facebook»
loyihasi muvaffaqiyatsiz chiqqanida nima qilardingiz?» deya
so‘rashadi. Uning aytishicha, agarda loyiha o‘xshamaganida muhandis
bo‘lib ishlagan bo‘lardi.
Mark 18 yoshida «Microsoft» uning «Synapce Media Player» dasturini
sotib olmoqchi bo‘ladi. Mark keyinchalik «Facebook»ning
asoschilaridan biriga aylangan do‘sti Adam Di Anjelo bilan sun’iy
xotirali dastur yaratishgan. Mazkur tizim mustaqil ravishda
foydalanuvchi yoqtiradigan musiqalarni yodida saqlab qolgan va unga
shu turdagi qo‘shiqlarni taqdim etgan.Ular o‘z loyihasini bepul
ko‘chirib olish uchun internetga joylashtirishadi va dastlabki
oylardayoq o‘z muxlislarini topadi. «Synapce Media Player» haqida

«Facebook»ning dastlabki to‘laqonli ofisi 2005 yilda Palo-Altoda ochilgan. Mazkur
shaharcha startaplar vatani hisoblanadi. Masalan, dunyoga taniqli HP
kompyuterlar kompaniyasi ham 1939 yili aynan shu yerda paydo bo‘lgan. Hyulett
va Pakkard ismli do‘stlar o‘zlarining garajida barcha ishni noldan boshlashgan.
1998 yilda esa shu yerda Larri Peyj va Sergey Brin «Google»ni «kashf qilishgan».
Avvaliga Sukerberg va uning jamoasi besh kishiga mo‘ljallangan uyni ijaraga
oladi. Bu yerda ular nafaqat ishlardi, balki yashagan ham.
Ular uyning devorlarini Devid Chou ismli graffiti-rassomning ishlari bilan
bezashga qaror qilishadi. U «Jaz-Z» va «Linkin Park» bilan birgalikdagi «Sollicion
Source» albomining muqovasi sabab mashhurlikka erishgan.«Facebook»
prezidenti Shon Parker esa Chou ijodining muxlisi bo‘lgan. Chouning ishi 60 ming
dollarga baholangan. Biroq oson yo‘ldan yurishni yomon ko‘radigan Parker
Chouga pul o‘rniga xuddi shuncha miqdorga teng «ijtimoiy tarmoq» aksiyasini
taklif qilgan. Rassom rozi bo‘lgan va «Facebook» IPO (qimmatli qog‘ozlar
bozori)ga chiqqanida Chou 200 million dollarni qo‘lga kiritgan.

VCh tebranish tayanch fazasi o'zgarganda, SD (Signal Demodulation) chiqishdagi NCh tebranish fazasining o'zgarishi uchun bir necha sabablarni ko'rib chiqish mumkin.
1. Quyidagi sinovlar: VCh tebranish tayanch fazasi o'zgarganda, ovoz, sifatli signal yoki boshqa kirish signalining fazasidagi o'zgarishlarni tekshirish uchun sinovlar qo'llaniladi. Bu sinovlar orqali tayanchdagi ovozni qayta tiklash mumkin.
2.Fazoviy Modulyatsiya (PM): Agar VCh tebranish tayanch fazasi o'zgarganda, PM usullari orqali tashqi signalni qayta tiklashda fazaning o'zgarishi muhim bo'ladi. Fazoviy modulyatsiya (PM) tizimlari fazaning o'zgarishiga hisob-kitoblarni tekshiradi va tashqi signalni boshqarishda qulaylik yaratadi.
3.Demodulyator tizimi: Tebranish fazalari o'zgarishlarini qayta tiklash uchun mo'ljallangan demodulyator tizimi ishlatiladi. Bu tizimlar VCh tebranish tayanch fazasi o'zgarganda tashqi signalni boshqarish va unga moslashish uchun ilg'or modifikatsiyalarga ega bo'lib, demodulyatsiya jarayonini bajaradilar.
4.Fazaning qayta tiklanishi: VCh tebranish tayanch fazasi o'zgarganda, fazaning qayta tiklanishi muhim bo'lib, bu NCh tebranish fazasining o'zgarishiga olib keladi. Bunday qayta tiklanishlar signalni muhofaza qilishda va to'g'ri aniqlashda yordam beradi.
5.Tizimning o'z xususiyatlari: Tizimlar va signal qayta ishlash jarayonlari mutlaqo tizimning xususiyatlariga bog'liq. Har bir tizim uchun tayyorlanganlar, VCh tebranish tayanch fazasi o'zgarishini oldini olish uchun mavjud bo'lgan texnologiyalarni va dastlabki o'lchovlarni hisobga olishadi.
Ushbu sabablarga ko'ra, VCh tebranish tayanch fazasi o'zgarganda, SD chiqishdagi NCh tebranish fazasi o'zgarishi signalni tiklash va ma'lumotlar qayta ishlash jarayonlarida o'zgarishlar yuzaga kelishi mumkin.

Mavzu: Kompleks sonlar va ular ustida amallar.
Bajardi: “KTI-293” guruh talabasi Amonqulov Boboqul
Qabul qildi: G’ulomova Muhabbat
Qarshi 2013
Reja:
1. Asosiy ta‘riflar.
2. Kompleks sonning geometrik tasviri.
3. Kompleks sonning trigonometrik shakli.
1. Asosiy ta‘riflar
Haqiqiy sonlar bilan ish ko’rilganda noldan farqli har qanday haqiqiy sonni kvadrati musbat bo’ladi deyilgan edi. Ammo kvadrati manfiy bo’lgan sonlar bilan ham ish ko’rishga to’g’ri keladi. Bunday sonlar tabiiyki haqiqiy son bo’lmaydi.
1-ta‘rif. Kvadrati –1 ga teng ifodani mavhum birlik deb ataladi va u i orqali belgilanadi.
Shunday qilib, i2=-1 yoki .
Mavhum birlikning ta‘rifidan i3= i2· i =-1·i=i, i4=i2·i2=(-1)(-1)=1, i5=i va hokazo umuman k butun son uchun i4к=1, i4к+1= i, i4к+2=-1, i4к+3=-i ekannligi kelib chiqadi.
2-ta‘rif. z kompleks son deb
z=а+bi
ko’rinishdagi ifodaga aytiladi, bunda а va b haqiqiy sonlar.
a va b ni z kompleks sonning haqiqiy va mavhum qismlari deyiladi va Rez=a, jmz=b
kabi belgilanadi.
Xususiy holda, agar а=0 bo’lsa u holda z=0+ib=bi bo’lib u sof mavhum son deyiladi. Agar b=0 bo’lsa z=a+i0=a haqiqiy son hosil bo’ladi. Demak, haqiqiy va sof mavhum sonlar kompleks sonning xususiy holi.
3-ta‘rif. Ikkita z1=a1+ib1 va z2=a2+ib2 kompleks sonlar а1=а2 b1=b2 bo’lgandagina teng (z1=z2) deyiladi.
Demak haqiqiy qismlari o’zaro va mavhum qismlari o’zaro teng bo’lgan kompleks sonlar teng bo’lar ekan.
4-ta‘rif. Ham haqiqiy qismi ham mavhum qismi noldan iborat kompleks son nolga teng deyiladi.
Demak, а=0, b=0 bo’lgandagina z=0 va aksincha z=a+ib=0 dan а=0, b=0 kelib chiqadi.
5-ta‘rif. Faqat mavhum qismining ishorasi bilan farq qiluvchi ikkita z=a+ib va =a-ib kompleks sonlar o’zaro qo’shma kompleks sonlar deyiladi.
6-ta‘rif. Haqiqiy va mavhum qismlarining ishoralari bilan farq qiluvchi ikkita z1=a+ib va z2=-a-ib= –z1 kompleks sonlar qarama – qarshi kompleks sonlar deyiladi.

TOPSHIRIG’I
Topshirdi: Zaylobidinov Sh
Qabul qildi: Ro’zaliyev A
Mavzu: Old detektor kaskad o’rniga klassifikatorlar daraxti
Ishdan maqsad: Old detektor kaskad o’rniga klassifikatorlar daraxtiini o’rganish va ularni qo’llanilish sohalari bilan tanishish.
Kerakli johozlar: kompyuter hamda internet.
Nazariy qism
"Detektor kaskad" deb nomlanadigan usul, ob'ektlarni aniqlash uchun kamayishga qolgan bir nechta klassifikatorlarni ishlatish asosida ishlaydigan bir ob'ekt aniqlash algoritmi yoki modelidir. Detektor kaskadlar, muayyan bir ob'ektning (masalan, yuz yoki avtomobil) mavjudligini aniqlash uchun bir nechta kengaytirilgan haqiqiy sonlarni ishlatadilar.
Detektor kaskad, qatorda bir nechta qadamdan iborat bo'ladi, har bir qadam esa bir klassifikator tomonidan bajariladi. Klassifikatorlar, ob'ektlarning turini aniqlash uchun o'rganilgan modellar bo'lishi mumkin. Misol uchun, AdaBoost yoki Haar-like xususiyatlarni ishlatadigan AdaBoost algoritmasi foydalanilishi mumkin.
Old detektor kaskadlari, o'rtacha ishlaydigan algoritmlardan biri bo'lib, ob'ektlarni aniqlash uchun yuqori aniqlash darajasi bilan birlikda tez ishlov berishga imkon beradi. Bunday kaskadlar, muayyan bir aniqlash darajasi o'rniga ob'ektlarni aniqlash uchun tez va samarali bo'lishi uchun keng ishlatilgan.
Bundan tashqari, yangi texnologiyalar va algoritmlar, klassifikatsiya uchun boshqa usullarni ham rivojlantirgan. Misol uchun, evolyutsioner algoritmlar, sinir tarmoqlar, konvolutsion tarmoqlar (CNN) va kuchi bo'yicha usullar ob'ektlarni aniqlashda keng tarqalgan. Bu usullar qisqa vaqt davomida yuqori aniqlash natijalarini berishga imkon beradi.
Bundan tashqari, detektor kaskadlari ham rivojlantirilgan va yangilangan. O'zgaruvchilarni o'rganish, bir-biriga bog'liqligini hisoblash uchun kengaytirilgan usullar va qo'shimcha kengaytirilgan algoritmlar kiritilgan. Bu yangilashlar ob'ektlarni aniqlashning yuqori darajada samarali bo'lishiga yordam beradi.

Bog'liq 15- labor3. Ma’lumotlarning sirqib chiqishini oldini olish tizimlari (Data Leakage Prevention, DLP).
DLP tizimi nafaqat ma’lumotlarni sirqib chiqishidan, balki umuman ma’lumotlar omborini himoyalash va iqtisodiy xavfsizlikni ta’minlash uchun ishlatiladi. Uning birinchi asosiy vazifasi ma’lumotlarni chiqib ketishini saqlashga asoslangan, chunki har qanday ma’lumotlarni sirqib chiqib ketishi katta moliyaviy zaralarni keltirishi mumkin.
Ushbu tizimning ikkinchi vazifasi ushlab olingan arhivni belgilab chiqish, ya’ni belgilanmasdan ushlash arxivi - bu faqat to'liq matnli qidiruv yordamida ishlash mumkin bo'lgan katta ma'lumotlar to'plami, lekin u har doim ham yordam bermaydi. Masalan, sizda 16 ta raqamdan iborat kredit karta raqamingiz mavjud. Bu raqam yozishmalar har qanday formatda yozilishi mumkin: barcha raqamlar birlashtiriladi, turli ajratgichlar bilan 4 ta raqamdan iborat guruhlarga bo’linadi. Bunday karta raqamini ushlash arxivida to'liq matnli qidiruvni topish deyarli mumkin emas. Ammo bu erda yordam oddiy shaklga ega. Traffic Monitor «Credit card» matn ob'ektiga ega bo'lib, formatlashdan qat'iy nazar kreditlarni ushlaydi. Shundan so'ng, u har qanday formatlashni olib tashlab, normal shaklni ajratadi. Oddiy shakl ma'lumotlar bazasida (MB) ushlangan ob'ektga nisbatan saqlanadi. Keyin, qidirishda karta raqami istalgan formatda o'rnatilishi mumkin, u ham oddiy shaklga ega bo'ladi.
2019 yilda DLP tizimini sotilgani 1,65 milliard dollarga etgan. Konteynerli tahlil. Bu usul ma'lumot joylashgan fayl yoki boshqa konteyner (arxiv, kriptodisk va boshqalar) xususiyatlarini tahlil qiladi. Har bir konteynerda konteyner ichidagi tarkib turini noyob tarzda aniqlaydigan yorliq bo’ladi. Ushbu usullar amalda ko'chirilayotgan ma'lumotlarni tahlil qilish uchun hisoblash resurslarini talab qilmaydi, chunki yorliq foydalanuvchining kontentini istalgan yo'nalish bo'ylab ko'chirish huquqlarini to'liq tavsiflaydi. Ushbu yondashuvning afzalliklari tahlil tezligi va ikkinchi turdagi xatolarning yo'qligi hisoblanadi.
