CS 1652: Data Communication and Computer Networks …

from the application layer to the data-link layer. Concurrent with the lectures, you (in groups of two) will be building a functional TCP/IP stack and a small web server that will run on it.

Foundations of Artificial Intelligence

“The branch of computer science that is concerned with the automation of in-telligent behavior” (Luger+Stubblefield, 1993) Views of AI fall into four categories: Thinking humanly Thinking rationally Acting humanly Acting rationally Examining these, we will plump for acting rationally (sort of) AIMA Chapter 1 (after Russell and Norvig) 3

Sets and set operations - University of Pittsburgh

• Ordered-n tuples are used to represent an ordered collection. Definition: An ordered n-tuple (x1, x2, ..., xN) is the ordered collection that has x1 as its first element, x2 as its second element, ..., and xN as its N-th element, N 2. Example: • Coordinates of a point in the 2-D plane (12, 16) x y

Mathematical induction & Recursion

Mathematical induction • Used to prove statements of the form x P(x) where x Z+ Mathematical induction proofs consists of two steps: 1) Basis: The proposition P(1) is true. 2) Inductive Step: The implication P(n) P(n+1), is true for all positive n. • Therefore we conclude x P(x).

Introduction to Generalized Linear Models

Introduction Generalized Linear Models Structure For example, a common remedy for the variance increasing with the mean is to apply the log transform, e.g. log( yi) = 0 + 1 x 1 + i) E (log Y i) = 0 + 1 x 1 This is a linear model for the mean of log Y which may not always be appropriate. E.g. if Y is income perhaps we are really interested

Poisson Models for Count Data

4.1 Introduction to Poisson Regression As usual, we start by introducing an example that will serve to illustrative regression models for count data. We then introduce the Poisson distribution and discuss the rationale for modeling the logarithm of the mean as a linear function of observed covariates. The result is a generalized linear model with
