Quiz 2 Review Session

This recitation reviews the details of directed and undirected node graphs as well as explaining the difference between depth-first search and breath-first search with an extensive explanation of the code involved in graph creation and the search methods

Recitation 9: Directed and Undirected Node Graphs

This recitation reviews hierarchical and kmeans clustering in great detail with many different code examples. It also discusses the merits and disadvantages of both clustering and how to calculate error.

Recitation 8: Hierarchical and k-means Clustering

This recitation video covers some basic probability and statistics, as well as simulation methods for estimating unknown probabilites.  Includes worked examples, probability distributions, mean and standard deviation, and plotting graphs in Python.

Recitation 6: Probability and Statistics

This recitation discusses different types of data distributions, Monte Carlo simulations and data curve regressions in great detail and is heavy in code examples and explanations.

Recitation 7: Distributions, Monte Carlo, and Regressions

This recitation goes over the answers to Quiz 1 and introduces object-oriented programming (classes) in comparison to types.

Recitation 5: Quiz 1 Answers and Object-Oriented Programming

This recitation covers lists, list elements, and a discussion of sorting techniques.  Introduces recursion, base cases, and simplifying problems.

Recitation 3: Lists and their Elements, Sorting, and Recursion

This recitation further explains recursion, pseudo code and debugging with several examples. The recitation also talks about optional parameters and floating point comparisons and float's representation in python.

Recitation 4: Recursion, Pseudo code, and Debugging

OCW Scholar: Introduction to Computer Science and Programming

this is a great place to start with python and programming just great

this is great

I had seen this on opencourseware website before the release of iTunes u, and it was great. They teach the basic concepts all programmers should know for any language. They teach in python, but the application of knowledge is for any program. Highly recommend.
