Artificial Intelligence (AI) simulates human intelligence through machines, enabling them to perform tasks like decision-making, problem-solving, and natural language processing. **Subfields of AI**: 1. **Natural Language Processing (NLP)**: Understanding and generating human language (e.g., chatbots, translation). 2. **Computer Vision**: Analyzing visual data for applications like facial recognition. 3. **Robotics**: Building intelligent machines to automate physical tasks. **Tools and Frameworks**: - **Python Libraries**: TensorFlow, Keras, OpenCV. - **Cloud AI Services**: Google AI, AWS AI, Azure AI. Real-world applications: - Predictive analytics in healthcare and finance. - Autonomous vehicles and drones. - Personal assistants like Siri and Alexa. To start with AI, work on small projects like sentiment analysis or object detection. Dive deeper into mathematical foundations like linear algebra and probability to master this field.
