A Bayesian Approach to Diagnosing Problems with Prolog Control Flow
نویسندگان
چکیده
The use of uncertain reasoning techniques have recently been advocated as a means of diagnosing errors in terms of both performance and conceptual understanding (Petrushin & Sinitsa 1993; Martin & VanLehn 1993; Tokuda & Fukuda 1993; Sime 1993). In this paper, we describe an investigation of the utility of a simple uncertain reasoning (Bayesian) technique for the diagnosis of novice Prolog programmer’s misconceptions aboutProlog control flow. We find that, while the use of more sophisticated techniques may mitigate some of the difficulties, there are certain fundamental problems connected with the nature of misconceptions that need to be overcome before such techniques can be used with confidence.

Monitoring and diagnosing a two-stage production process with attribute characteristics
Multistage process monitoring has recently attracted notable attention in that the statistical relationships between quality variables are taken into account. Here, we dealt with the problem of monitoring and diagnosing a two-stage production process with attribute characteristics in which the outgoing quality variable is impacted by the incoming quality variable from the first process stage....

This paper presents an extension of Bayesian networks (BN) applied to reliability analysis of an open gas generator cycle Liquid propellant engine (OGLE) of launch vehicles. There are several methods for system reliability analysis such as RBD, FTA, FMEA, Markov Chains, and etc. But for complex systems such as LV, they are not all efficiently applicable due to failure dependencies between compo...

متن کاملA Bayesian Approach for the Recognition of Control Chart Patterns
In this research, an iterative approach is employed to recognize and classify control chart patterns. To do this, by taking new observations on the quality characteristic under consideration, the Maximum Likelihood Estimator of pattern parameters is first obtained and then the probability of each pattern is determined. Then using Bayes’ rule, probabilities are updated recursively. Finally, when...
