Machine ki pariksha: naye examples se
Tumne chhoti behen ko 5 phal dikha kar naam sikhaye. Kaise pata karoge ki usne sach mein seekha ya bas yaad kar liya?
Socho pehle… phir dekho jawab
Use naye phal dikhao jo usne pehle nahi dekhe! AI ke saath bhi aisa hi hota hai: kuch examples se sikhate hain (training), aur alag rakhe naye examples se jaanchte hain (testing).
Zoya ne computer club mein ek machine ko 'khush chehra' aur 'udaas chehra' pehchaanna sikhaya. Usne 10 chitron mein se 7 sikhaane ke liye diye aur 3 alag rakhe. Dost bola, 'Saare 10 de do, machine poori sahi aayegi!' Zoya ne kaha, 'Phir pata kaise chalega ki usne sach mein seekha?'
Cause-effect: jo chitra machine pehle dekh chuki hai, unpar sahi aana aasaan hai. Asli pariksha naye chitron par hoti hai. Wahan galti ho, toh machine ko aur alag-alag examples chahiye.
Sahi naam (label) bhi zaroori hai: agar kisi ne galti se udaas chehre ko 'khush' likh diya, toh machine galat seekhegi. Isliye AI banane wale apna data dhyaan se jaanchte hain.
Ghar pe try karo
8 chhoti parchiyon par chehre banao: 4 khush, 4 udaas, sab thode alag. 5 parchiyan dikha kar ghar ke kisi sadasya ko sikhao, 3 alag rakh do. Phir woh 3 dikha kar poochho: 'Khush ya udaas?' Kitne sahi aaye, likho.
Wow!
Bade AI bhi pariksha dete hain — unke liye kuch data pehle se alag rakh diya jaata hai, jise unhone kabhi nahi dekha!
Mummy-Papa ke liye
Aaj bachche ke parchi wale khel mein 'seekhne wale' baniye; 3 nayi parchiyon par jawab dijiye aur bachche ko score likhne dijiye.
3 sawaal
- Zoya ne 3 chitra alag kyun rakhe?
Jawab dekho
Machine ki asli pariksha naye chitron se karne ke liye. Naye chitron par sahi aana hi batata hai ki machine ne sach mein seekha.
- Agar udaas chehre par galti se 'khush' likha ho, toh kya hoga?
Jawab dekho
Machine galat seekhegi. Galat label se machine galat pattern seekhti hai.
- AI ko sikhaane wale examples ko kya kehte hain?
Jawab dekho
Training data. Seekhne wale examples training data, jaanchne wale testing data kehlaate hain.
