- Computer Vision: An area of AI that enables computers to interpret and make decisions based on visual data from the world.
2. Historical Context
Understanding the historical context of AI helps learners appreciate the progress made in the field. Key milestones include:
- 1956: The Dartmouth Conference, where the term "artificial intelligence" was coined.
- 1960s-70s: Development of early AI programs like ELIZA and the advent of expert systems.
- 1980s: The rise of machine learning and the first AI winter, a period of reduced funding and interest.
- 1997: IBM's Deep Blue defeats chess champion Garry Kasparov, marking a significant milestone in AI.
- 2010s: Breakthroughs in deep learning drive advancements in image recognition, speech recognition, and NLP.
Core Concepts in AI 102
AI 102 builds on basic AI principles to explore more complex ideas and technologies. This section outlines the core concepts that students should focus on.
1. Types of AI
AI can generally be classified into three categories:
- Narrow AI: AI systems designed to perform a narrow task (e.g., voice assistants).
- General AI: A theoretical form of AI where a system possesses the ability to perform any intellectual task that a human can do.
- Superintelligent AI: An advanced form of AI that surpasses human intelligence across virtually all areas.
2. Machine Learning Algorithms
A significant part of AI 102 involves understanding various machine learning algorithms, including:
- Supervised Learning: The model is trained on labeled data. Examples include regression and classification tasks.
- Unsupervised Learning: The model finds hidden patterns or intrinsic structures in the input data. Examples include clustering and association.
- Reinforcement Learning: An agent learns to make decisions by receiving rewards or penalties for actions taken within an environment.
3. Neural Networks
Neural networks are pivotal to deep learning and AI. Students should understand:
- Architecture: The structure of neural networks, including input layers, hidden layers, and output layers.
- Activation Functions: Functions that determine whether a neuron should be activated, such as sigmoid, ReLU, and softmax.
