Introduction to AI
-
-
Four Approaches to AI
Think Human
AI systems that try to copy how humans think, like remembering things or solving problems, often using models from psychology
-

-
Turing Test
Purpose of the test
To determine if a machine can produce human-like responses that fool a human evaluator into thinking it's human
-
-
The test is conducted by having a human evaluator engage in text based conversations with both a machine and a human, without knowing which is which. If the evaluator cannot consistently tell them apart, the machine is considered to have passed the test
-
Consciousness and AI
Sentience and awareness
Sentience is the ability to feel and experience things, like pain or joy. Awareness means recognizing your environment and your own state. While humans possess both, AI systems can only simulate them without truly feeling or knowing anything
Philosophical debates
There is ongoing debate about whether machines could ever be conscious. Some argue consciousness requires more than data processing, it might need subjective experience or a "mind." Others believe it's possible if AI becomes complex enough

Real-World Applications
Game playing
AI systems like OpenAI Five show how machines can master complex, fast paced games with human-level performance
Autonomous vehicles
AI uses perception, decision-making, and real-time reaction to navigate roads safely, like with the Waymo self driving technology
Speech recognition
AI systems like Whisper by OpenAI convert spoken language into text accurately, enabling hands-free tech, transcription, and accessibility tools
Robotics
Boston Dynamics' Atlas robot applies AI to balance, move, and interact with physical environments in real time

Rational Agents
-
Agents in AI are systems that can make decisions and act in an environment to achieve specific goals
Spam filtering
AI identifies and blocks unwanted messages using pattern detection, improving email productivity and digital security like with Gmail
