At its core, AI is about creating systems that can perform tasks that typically require human intelligence. This broad definition encompasses a wide range of techniques and applications. Here are a few key concepts to familiarize yourself with:

• Machine Learning (ML): Often used interchangeably with AI, machine learning is a subset of AI that focuses on enabling systems to learn from data without being explicitly programmed. Instead of writing specific rules for every scenario, ML algorithms identify patterns in data and use those patterns to make predictions or decisions. Think of spam filters that learn to identify unwanted emails based on examples of spam and non-spam.

  
  

• Deep Learning (DL): A subfield of machine learning, deep learning utilizes artificial neural networks with multiple layers (hence "deep") to analyze complex data like images, audio, and text. These networks are inspired by the structure of the human brain and have achieved remarkable success in areas like image recognition, natural language processing, and speech recognition. Consider how facial recognition software can identify individuals in photos or videos – that's often powered by deep learning.

  
  

• Natural Language Processing (NLP): This branch of AI focuses on enabling computers to understand, interpret, and generate human language. From virtual assistants like Siri and Alexa to translation services and sentiment analysis tools, NLP plays a crucial role in bridging the gap between human communication and machine understanding.   

• Computer Vision: As the name suggests, computer vision deals with enabling computers to "see" and interpret visual information from the world around them. This includes tasks like object detection in images, autonomous vehicle navigation, and medical image analysis.
