CSE 4308 Assessment

Due dates:

Written parts (part 1 and part 2): Tuesday October 23, 2012, 11:59pm.
Programming parts (part 3 and part 4): Monday October 22, 2012, 11:59pm.

Summary

The goal of this assessment is to evaluate:

theoretical understanding of inference methods for knowledge bases that use propositional logic, and
the practical ability to design and implement such inference methods.

Four tasks need to be completed:

Answering some written questions about propositional logic inference methods.
Formulating parts of an inference engine in pseudocode.
Designing a knowledge base to represent some specific known facts about an environment.
Implementing an inference engine in software.

Part 1: (50 points) Understanding knowledge bases and inference methods.

Questions 1, 2, 3, of written assignment 3.

Part 2: (50 points) Formulating an inference engine.

Questions 4, 5, 6, and 7 of written assignment 3.

Part 3: (40 points) Data analysis and representation.

Create a knowledge base capturing the known facts about wumpus environments that are stated in programming assignment 3 (40% of programming assignment 3).

Part 4: (60 points) Implementing an inference engine.

Implement an inference engine that can determine, given a knowledge base and a statement, if given the knowledge base the statement is definitely true, definitely false, or neither (60% of programming assignment 3).

Grading Rubric

In addition to the quantitative score of total points earned, there will also be a qualitative grade for each part, and for the assessment as a whole. The qualitative grade can have the following five values: poor, fair, acceptable, goods, excellent. The qualitative grade, for each of the four parts, and for the assessment as a whole, will be assigned as follows:

0%-29%: poor
30%-59%: fair
60%-74%: acceptable
75%-89%: good
90%-100%: excellent

Important Note

Undergraduate students achieving a semester grade of C or better, but failing the assessment (below 60%) and documenting their circumstances will be assigned a semester grade of I (incomplete) and may re-attempt the assessment in the next semester. If the assessment is then passed, the semester grade will be changed from I to the achieved grade.
