Introduction to AI Subfields

Artificial intelligence (AI) is a broad field encompassing many specialized areas. This tutorial explores some key subsets of AI: Machine Learning, Deep Learning, Natural Language Processing, Expert Systems, Robotics, Machine Vision, and Speech Recognition. Machine learning, in particular, plays a central role in the development of many AI systems.

1. Machine Learning

Machine learning (ML) enables computers to learn from data without explicit programming. ML algorithms identify patterns in data to make predictions or decisions. The system's performance improves with more data and experience.

Types of Machine Learning:

  • Supervised Learning: Trains a model on labeled data (input-output pairs) to predict outputs for new inputs (e.g., classification, regression).
  • Unsupervised Learning: Discovers patterns in unlabeled data (e.g., clustering, association rule mining).
  • Reinforcement Learning: An agent learns by taking actions and receiving rewards or penalties (e.g., game playing, robotics).

2. Natural Language Processing (NLP)

Natural Language Processing (NLP) allows computers to understand, interpret, and generate human language. NLP is essential for AI systems to interact with humans using natural language. It’s used in applications like virtual assistants (Siri, Google Assistant), chatbots, and machine translation.

3. Deep Learning

Deep learning is a subfield of machine learning using artificial neural networks with multiple layers (hence "deep"). These networks can learn complex patterns in data. Deep learning powers many applications, including self-driving cars, image recognition, and speech recognition. Deep learning typically requires large datasets and significant computational resources.

4. Expert Systems

Expert systems use human expertise to solve complex problems. They incorporate a knowledge base (facts and rules) and an inference engine (to draw conclusions) to provide expert-level advice or make decisions.

5. Robotics

Robotics involves designing, building, and programming robots. AI is used to create intelligent robots capable of complex tasks and interaction with their environment. (An example like Sophia the robot would be mentioned here.)

6. Machine Vision

Machine vision enables computers to "see" and interpret images and videos. It uses computer vision techniques and often incorporates machine learning for object recognition and other visual tasks.

7. Speech Recognition

Speech recognition converts spoken language into text. It's used in many applications (virtual assistants, dictation software). Systems can be speaker-dependent (trained on a single person's voice) or speaker-independent (trained on multiple voices).
