Catalog Description:
Probability theory, random variables and stochastic processes. Response of linear systems to stochastic
inputs. Applications in engineering. (4 credit hours).
Course Prerequisites:
EE 171 Signals & Systems and STAT 151, Applied Probability.
(Basic knowledge of Linear Algebra, Vector Spaces, Probability & Statistics, Signals & Systems. Programming experience in a high level language.)
Course Objectives: The objectives of this course are to:
• understand the fundamental meaning of probability and fundamental concepts of random variables
and stochastic processes.
• understand basic concepts of Bayesian analysis, features and classifiers.
Course Outcomes: Upon satisfactory completion of the course, the student will be able to:
• solve problems in discrete and continuous probability ranging from ”counting” problems to problems
involving signal and noise.
• propose possible methods to resolve basic problems in data analysis requiring dimensionality reduction, feature extraction and classifying data. Provide an error analysis.
Course Lectures: We have some 15 weeks of classes for are a total of 25 lectures (100 minutes each).
Lectures and associated readings are as follows.
(Note that allocated time and order of presentation may vary somewhat from that described below.)
• Lectures 1 & 2: Classic and frequency definition of probability; binomial distribution; Gaussian
distribution. Analysis versus computer simulation. Used random number generator to generate
desired distribution. Histograms and pdfs. Multiple random variables. Scattergrams. (Chs. 1,2,
Kay).
• Lecture 3 & 4. Concept of a set. Set elements, subsets and set operations. Assigning and determining probabilities using sets. Notion of an event. Axioms of probability. Finite and countably
infinite sets. Properties of probability functions. Continuous sample spaces. Combinatorics. Binomial probability law. Application and computer simulation. (Ch.3, Kay, Ch.2 PP).
• Lectures 5: Conditional probability. Joint events. Independence and mutually exclusive events.
Bayes theorem. Examples with medical diagnosis, cluster recognition. (Ch.4, Kay, Chs.2.3, 3.1, 3.2
PP).
• Lecture 6: Random variable (RV) and probability of a random variable. Important probability
mass functions (PMFs). Functions of a random variable. Cumulative Distribution functions (CDF).
Computer Simulation. Supermarket example. (Ch.5 Kay, Chs.4.1, 4.2, 4.3 PP).
