What is AI |
AI is the study and design of intelligent agents, where an agent is a system that perceives it's environment and takes an action that maximises it's chance of success |
|
|
Rational system |
A system is rational if it performs the right thing given what it knows. |
|
|
The four approaches to AI |
Thinking Humanly - cognitive science Acting Humanly - turing test Thinking Rationally - laws of thoughts , uses math and logic. Not all knowledge can be expressed and it can lead to computational blow up. Acting Rationally - rational agents |
|
|
Turing Test |
A computer passes the turing test if it can fool the human interrogator. The interrogator must not the able to differentiate between the answers given by a human and a computer. When they are hidden from sight. |
|
|
Application of AI |
Virtual assistants Handwriting recognition Machine translation Robotics Autonomous driving Etc |
|
|
Turing test problems |
The turing test is not reproducible, amenable or constructive to mathematical analysis |
|
|
What is agent function |
It is a function that maps the set of percepts to action. |
|
|
What is agent program/ architecture |
It runs on a physical architecture to produce the agent function |
|
|
Some fields that contribute to AI |
Philosophy - logic Mathematics - formulation of logic Economic - rational decision, game theory Computer engineering - how to build machines that make AI possible. Etc |
|
|
Rationality |
Measure of how to act to maximize a performance measure |
|
|
Agent |
Is anything that perceives it's environment thru sensors and acts on the environment using actuators. |
|
|
Is rationality always possible |
No |
|
|
Learning |
Agents improve their performance through learning. |
|
|
Uninformed search |
These strategies only use the information available in the problem definition. |
|
|
Tree search vs graph search |
Tree search has no explored nodes list Graph search has a explored nodes list So one keeps track the other doesn't. |
