TEACH-TIE: A PROGRAM FOR TEACHING A CHILD WITH AND A CHILD WITHOUT AUTISM TO TIE THEIR SHOELACES USING VIDEO PROMPTING AND BACKWARDS CHAINING

Montalmont, Bianca January 2018 (has links)
This project sought to evaluate the effects of video prompting in combination with backwards chaining to increase proficiency of tying shoe-laces using a changing criterion design. Two children, one diagnosed with Autism Spectrum Disorder (ASD) and one neurotypical were invited to participate in this study. Following baseline, shoe-tying prompt videos and backwards chaining were used to teach shoe-tying. Video prompting plus backwards chaining increased the typically developing participant’s proficiency with performing a larger percentage of steps of the targeted skill independently following intervention. However, the participant with ASD was unable to meet criterion and the study was terminated for him due to challenging behavior. These results indicate that the combination of point-of-view video prompts along with backwards chaining can be effective in teaching children to tie their shoelaces. These results also indicate that children with ASD may need additional supports with this intervention to reach acquisition criterion. Parents reported satisfaction both with the procedures undertaken and with the outcomes of the intervention. / Applied Behavioral Analysis

Integrating Expert System and Geographic Information System for Spatial Decision Making

Shesham, Sriharsha 01 December 2012 (has links)
Spatial decision making is a process of providing an effective solution for a problem that encompasses semi-structured spatial data. It is a challenging task which involves various factors to consider. For example, in order to build a new industry, an appropriate site must be selected for which several factors have to be taken into consideration. Some of the factors, which can affect the decision in this particular case, are air pollution, noise pollution, and distance from living areas, which makes the decision difficult. The geographic information systems (GIS) and the expert systems (ES) have many advantages in solving problems in their prospective areas. Integrating these two systems will benefit in solving spatial decision making problems. In the past, many researchers have proposed integrating systems which extracts the data from the GIS and saves it in the database for decision making. Most of the frameworks which have been developed were system dependent and are not properly structured. So it is difficult to search the data. This thesis proposes a framework which extracts the GIS data and processes it with the help of ES decision making capabilities to solve the spatial decision making problem. This framework is named GeoFilter. This research classifies various types of mechanisms that can be used to integrate these two systems.

Practical Applications of Extended Deductive Databases in DATALOG*

Seipel, Dietmar January 2010 (has links)
A wide range of additional forward chaining applications could be realized with deductive databases, if their rule formalism, their immediate consequence operator, and their fixpoint iteration process would be more flexible. Deductive databases normally represent knowledge using stratified Datalog programs with default negation. But many practical applications of forward chaining require an extensible set of user–defined built–in predicates. Moreover, they often need function symbols for building complex data structures, and the stratified fixpoint iteration has to be extended by aggregation operations. We present an new language Datalog*, which extends Datalog by stratified meta–predicates (including default negation), function symbols, and user–defined built–in predicates, which are implemented and evaluated top–down in Prolog. All predicates are subject to the same backtracking mechanism. The bottom–up fixpoint iteration can aggregate the derived facts after each iteration based on user–defined Prolog predicates.

MEDICAL EXPERT SYSTEM FOR AXIAL SPONDYLOARTHIRITIS

Laraib Fatima (19204162) 28 July 2024 (has links)
<p dir="ltr">Axial spondyloarthritis (axSpA), a disease that due to its complexity and rarity, presents challenges in diagnosis. With a focus on integrating expert knowledge into an intelligent diagnostic system, the research explores the intricate nature of axSpA, emphasizing the challenges associated with its diverse clinical presentation. By leveraging a comprehensive knowledge base curated by domain experts, encompassing insights into pathophysiology, genetic factors, and evolving diagnostic criteria of axSpA, the expert system strives to provide a nuanced understanding of the disease. The methodology employs a hybrid reasoning approach, combining both forward and backward chaining techniques. Forward chaining iteratively processes clinical data and available evidence, applying logical rules to infer potential diagnoses and refine hypotheses, while backward chaining starts with the desired diagnostic goal and works backward through the knowledge base to validate or refute hypotheses. Additionally, certainty theory is incorporated to manage uncertainty in the diagnostic process, assigning confidence levels to conclusions based on the strength of evidence and expert knowledge. By integrating knowledge base, forward and backward chaining, and certainty theory, the research aims to enhance diagnostic precision for this less common yet impactful inflammatory rheumatic condition, emphasizing the importance of early and accurate identification for effective management and improved patient outcomes. The results indicate a significant improvement in diagnostic accuracy, sensitivity, and specificity compared to traditional methods. The system's potential to enhance early diagnosis and treatment outcomes is discussed, along with suggestions for future research to further refine and expand the system.</p>
