Performance
Indicators (SPIs) -
SPIs are a subset of the abilities a student will be able to demonstrate upon successfully completing the course.
Outcome 1 (Students will demonstrate expertise in a subfield of study chosen from the fields of electrical engineering or computer engineering): 1. Using theory learned in class the students should be able to display speech waveforms and images for visually inspecting key information and cues needed for pattern recognition. Outcome 2 (Students will demonstrate the ability to identify and formulate advanced problems and apply knowledge of mathematics and science to solve those problems): 1. Using tools learned in class the students should be able to design feature extraction and pattern classification modules needed for putting together a pattern recognition system. Outcome 3 (Students will demonstrate the ability to utilize current knowledge, technology, or techniques within their chosen subfield): 1. Given a project at work, the students should be able to carry out literature survey, problem formulation, and experimental design by relating real-world pattern recognition problems to what they learn in class.
