Teaching and Teacher Education is an international journal committed to advancing knowledge on teacher practice, preparation and education, as well as professional development, across all stages of education from early childhood to higher education.
PHP (Hypertext Preprocessor) ek server-side scripting language hai jo mainly web development ke liye use hoti hai. Iska code server par run hota hai, aur result browser me HTML ke form me dikhai deta hai.
PHP ko Rasmus Lerdorf ne 1994 me create kiya tha, aur aaj bhi yeh WordPress, Facebook, Wikipedia jaise popular websites me use hoti hai.
Machine Learning (ML) ek aisi technology hai jisme computer data se seekhta hai — bina explicitly program kiye.
(Yani system khud pattern samajh kar decision lena seekhta hai.)
ML mainly Artificial Intelligence (AI) ka ek subfield hai — jo “learning from experience” par focus karta hai.
Machine Learning ke 3 main types hote hain:
Supervised Learning (Labelled data se seekhna)
Unsupervised Learning (Hidden patterns dhoondhna)
Reinforcement Learning (Trial & error se seekhna)
Data ML ka fuel hai — jitna quality data hoga, utni acchi learning aur accurate predictions milenge.
Common ML algorithms: Linear Regression, Decision Trees, Random Forest, Support Vector Machines (SVM), Neural Networks.
Applications har jagah hain — jaise email spam filter, recommendation systems (Netflix, YouTube), self-driving cars, aur speech recognition (Alexa, Siri).
ML models ko train karne ke liye training data aur testing data use hota hai — taaki accuracy aur performance check ki ja sake.
Deep Learning, Machine Learning ka ek advanced branch hai — jisme multi-layered neural networks use hote hain (jaise ChatGPT, image recognition systems).
Overfitting ek common problem hai ML me — jab model training data ko yaad kar leta hai, lekin new data par sahi perform nahi karta.
Future of ML bahut bright hai — healthcare, finance, education, aur automation me iska use badhta ja raha hai. 🚀
