Courses In This Program

Course 1 4 weeks

Introduction to Artificial Intelligence

In this course, you'll learn about the foundations of AI. You'll configure your programming environment to work on AI problems with Python. At the end of the course you'll build a Sudoku solver and solve constraint satisfaction problems.

Lesson 1

Welcome to Artificial Intelligence

Welcome to Introduction to Artificial Intelligence!

Lesson 2

Introduction to Artificial Intelligence

An introduction to basic AI concepts and the challenge of answering "what is AI?"

Lesson 3

Solving Sudoku With AI

In this lesson, you'll dive right in and apply Artificial Intelligence to solve every Sudoku puzzle.

Lesson 4

Setting Up Your Environment and Workspaces

If you do not want to use Workspaces, then follow these instructions to set up your own system using Anaconda, a popular tool to manage your environments and packages in python.

Lesson 5 • Project

Build a Sudoku Solver

Use constraint propagation and search to build an agent that reasons like a human would to efficiently solve any Sudoku puzzle.

Lesson 6

Constraint Satisfaction Problems

Expand from the constraint propagation technique used in the Sudoku project to the Constraint Satisfaction Problem framework that can be used to solve a wide range of general problems.

Course 2 4 hours

Classical Search

Learn classical graph search algorithms--including uninformed search techniques like breadth-first and depth-first search and informed search with heuristics including A*. These algorithms are at the heart of many classical AI techniques, and have been used for planning, optimization, problem solving, and more. Complete the lesson by teaching PacMan to search with these techniques to solve increasingly complex domains.

Lesson 1


Peter Norvig, co-author of _Artificial Intelligence: A Modern Approach_, explains a framework for search problems, and introduces uninformed & informed search strategies to solve them.

Lesson 2

Uninformed Search

Peter introduces uninformed search strategies—which can only solve problems by generating successor states and distinguishing between goal and non-goal states.

Lesson 3

Informed Search

Peter introduces informed search strategies, which means that they use problem-specific knowledge to find solutions more efficiently than an uninformed search.

Lesson 4

Classroom Exercise: Search

Complete a practice exercise where you'll implement informed and uninformed search strategies for the game PacMan.

Lesson 5

Additional Search Topics

References to additional readings on search.

Course 3 3 weeks

Automated Planning

Learn to represent general problem domains with symbolic logic and use search to find optimal plans for achieving your agent’s goals. Planning & scheduling systems power modern automation & logistics operations, and aerospace applications like the Hubble telescope & NASA Mars rovers.

Lesson 1

Symbolic Logic & Reasoning

Peter Norvig returns to explain propositional logic and first-order logic, which provide a symbolic logic framework that enables AI agents to reason about their actions.

Lesson 2

Introduction to Planning

Peter Norvig defines automated planning problems in comparison to more general problem solving techniques to set the stage for classical planning algorithms in the next lesson.

Lesson 3

Classical Planning

Peter presents a survey of Classical Planning techniques: forward planning (progression search) & backward planning (regression search).

Lesson 4 • Project

Build a Forward-Planning Agent

In this project you’ll use experiment with search and symbolic logic to build an agent that automatically develops and executes plans to achieve their goals.

Lesson 5

Additional Planning Topics

Peter discusses plan space search & situational calculus. Finish the lesson with readings on advanced planning topics & modern applications of automated planning.

Course 4 4 hours

(Optional) Optimization Problems

Learn about iterative improvement optimization problems and classical algorithms emphasizing gradient-free methods for solving them. These techniques can often be used on intractable problems to find solutions that are "good enough" for practical purposes, and have been used extensively in fields like Operations Research & logistics. Finish the lesson by completing a classroom exercise comparing the different algorithms' performance on a variety of problems.

Lesson 1


Thad Starner introduces the concept of _iterative improvement problems_, a class of optimization problems that can be solved with global optimization or local search techniques covered in this lesson.

Lesson 2

Hill Climbing

Thad introduces _Hill Climbing_, a very simple local search optimization technique that works well on many iterative improvement problems.

Lesson 3

Simulated Annealing

Thad explains _Simulated Annealing_, a classical global optimization technique for optimization.

Lesson 4

Genetic Algorithms

Thad introduces another optimization technique: _Genetic Algorithms_, which uses a population of samples to make iterative improvements towards the goal.

Lesson 5

Optimization Exercise

Complete a classroom exercise implementing simulated annealing to solve the traveling salesman problem.

Lesson 6

Additional Optimization Topics

Review similarities of the techniques introduced in this lesson with links to readings on advanced optimization topics, then complete an optimization exercise in the classroom.

Fantastic! Although, I wish the program included some Machine Learning elements since ML is also part of AI. Well, maybe in the next iteration of the program.

I loved it. After not coding actively for a few years, this really did provide me with the excitement to solve and understand elegant code. Its a brilliant course so far. I love the mentors and their quick response. I will definitely go for more courses after this.
