Artificial Intelligence (AI) and Data Science
**Artificial Intelligence (AI)** and **Data Science** are closely related fields that use data,
algorithms, and computing to solve problems and make decisions.

1. Artificial Intelligence (AI)
AI is the branch of computer science that enables machines to mimic human intelligence.

**Key areas of AI: -
* **Machine Learning (ML):** Systems learn from data without explicit programming.
* **Deep Learning:** Neural networks used for speech, vision, and NLP.
* **Natural Language Processing (NLP):** Helps computers understand human language.
* **Computer Vision:** Allows machines to analyze images/videos.
* Robotics and automation.
Add: Embrace Tomorrow's Health Solutions
**Applications of AI: * Chatbots and virtual assistants, * Self-driving cars
* Fraud detection, * Medical diagnosis, * Recommendation systems (Netflix, shopping apps)
