10 Questions
What is the purpose of a feature extractor in pattern classification?
A feature extractor is a program that inputs the data (image) and extracts features that can be used in classification.
Define a class in the context of pattern classification.
A class is a set of objects having some important properties in common.
What is the role of a classifier in pattern classification?
A classifier is a program that inputs the feature vector and assigns it to one of a set of designated classes or to the “reject” class.
List the stages of the Design Cycle in pattern classification as mentioned in the text.
Data collection, Feature Choice, Model Choice, Training, Evaluation, Computational Complexity
What is post processing in the context of pattern classification?
Use a feature vector provided by a feature extractor to assign the object to a category. Exploit context input dependent information other than from the target pattern itself to improve performance.
______ 1 Analysis phase includes: System request, Requirements definition, Models, Feasibility Analysis, Workplan, System proposal
System Analysis
System Analysis 2 All three ______ of the system are interlinked and dependent on each other
architectural views
System Analysis 3 BUSINESS PROCESS AND FUNCTIONAL MODELING Functional models describe ______ processes and the interaction of an information system with its environment. In object-oriented systems development, two types of models are used to describe the functionality of an information system: use cases diagrams activity diagrams. Use cases are used to describe the basic functions of the information system. Activity diagrams support the logical modeling of ______ processes and workflows. Both can be used to describe the current as-is system and the to-be system being developed. We’ll describe ______ process and functional modeling as a means to document and understand requirements and to understand the functional or external behavior of the system.

System Analysis 4 _____ USE CASE ANALYSIS
USE CASE
System Analysis 5 WHAT IS A USE CASE. A ______ depicts a set of activities performed to produce some output result. Each ______ describes how an event triggers actions performed by the system and the user. With this type of event-driven modeling , everything in the system can be thought of as a response to some trigger event.
