Computers are dumb...

...but we can make them do incredibly clever things

Let's take a look!

Policy on Generative AI

For programming assignments, use whatever you'd like, but cite it.

For written assignments, the use of generative AI is prohibited.*

*If you use gen AI only to rephrase for writing clarity,
you must submit an appendix with your original answers.

Academic Integrity

Don't post your solutions anywhere!

Don't discuss code or actual written answers

Disclose your collaborators, cite your sources

Violations will lead to an OSCCR report being filed

Additional penalties, including failing the course
without the option to withdraw

Classroom Policies

Don't be late

Bring a laptop/tablet*

No phones please!

Be respectful

Don't distract your classmates

Let's take a mental break!

Any questions for/about me?

Where did it all start?

Can Machines Think?

Alan Turing, 1950

Some Philosophical Questions...

Is a machine intelligent if it merely mimics human thinking?

Is a machine intelligent if it can fool a human into believing so?

Could you construct a machine whose workings you couldn't explain?

What does intelligence have to do with free will?

Thinking = symbol manipulation

"Intelligence can be replicated
using a computer program"

- Mathematicians in the 1950s

1956, Dartmouth College, workshop on AI

"The conjecture that every aspect of learning or any other feature of intelligence can be,
in principle, so precisely described that a machine can be made to simulate it"

What is an intelligent agent?

A system or program that perceives and interacts with its environment
while making informed decisions to achieve a certain goal or maximize some utility

A system or program that perceives and interacts with its environment
while making informed decisions to achieve a certain goal or maximize some utility

How does a program perceive its environment?

• Computer Vision
• Depth Sensors
• Language
• Explicit Representations

A system or program that perceives and interacts with its environment
while making informed decisions to achieve a certain goal or maximize some utility

How does a program interact with its environment?

• Physical Interactions
• Image Generation
• Language

A system or program that perceives and interacts with its environment
while making informed decisions to achieve a certain goal or maximize some utility

How does a program learn?

• Rule Based Systems
• Learning from Computation
• Learning from Data
• Learning from Mistakes

A system or program that perceives and interacts with its environment
while making informed decisions to achieve a certain goal or maximize some utility

How does a program reason?

• Objective Functions
• Utility
• Fairness
• Biases

Consider a Roomba (a robot vacuum)

Think about

• Percepts
• Interactions
• Learning/Inference
• Rationality

How about Netflix/Youtube/Amazon Recommendations?

Think about

• Percepts
• Interactions
• Learning/Inference
• Rationality

Categorizing AI Environments

• Fully Observable v/s Partially Observable
• Single Agent v/s Multi Agent
• Deterministic v/s Non-Deterministic
• Episodic v/s Sequential
• Static v/s Dynamic
• Discrete v/s Continuous
• Known v/s Unknown

Let's now think about building an AI

SEARCH

Representation: State Space Graph

Nodes: States or World Configurations

Edges: Actions

Edge Weights: Cost of Action

Successor/Transition Function: Set of Edges & Edge Weights

Path: Sequence of Actions

Solution: A Path leading from Start to Goal

SEARCH

Let us try and formalize the following problems.

Before next class, please review...

• Breadth First Search
• Depth First Search
• Uniform Cost Search
