Data Science Kya Hai?
Data Science ek interdisciplinary field hai jo data ko analyze karne, interpret karne aur usse valuable insights nikaalne ke liye techniques aur tools ka istemal karti hai. Iska main goal complex data ko samajhna, problems ko solve karna aur decision-making ko optimize karna hota hai.
Data Science mein kai cheezein shamil hoti hain:
1. Data Collection – Data ko gather karna (e.g., surveys, sensors, internet, etc.).
2. Data Cleaning – Raw data ko clean karna, jaise missing values ko handle karna.
3. Data Analysis – Data ke patterns, trends aur relationships ko samajhna.
4. Modeling & Machine Learning – Machine learning algorithms ka use karna data ke predictions aur insights ke liye.
5. Data Visualization – Data ko graphical form mein represent karna taaki insights easily samjhe jaa sake.
6. Data Interpretation – Data ke basis par strategic decisions lena.
Data Science Ke Future Uses:
1. Artificial Intelligence aur Machine Learning – Data Science ki techniques AI aur ML mein kaafi use hoti hain. Ye fields bahut rapidly grow kar rahi hain.
2. Healthcare – Patient data ka analysis karke predictive models banaye ja rahe hain, jisse treatment aur diagnosis improve ho sake.
3. Finance & Banking – Fraud detection, risk analysis, aur market predictions mein data science ka use ho raha hai.
4. E-commerce – Customer behavior ke analysis se personalized recommendations aur targeted marketing ki strategies banai ja rahi hain.
5. Autonomous Vehicles – Self-driving cars ko train karne ke liye data science techniques ka use hota hai.
6. Smart Cities – Urban planning, traffic management, aur resource distribution ke liye data science ki zarurat hai.
