Lessons learned in developing CASIP (computer-assisted socratic instructional program) a CAI authoring tool, about the scope and limitations of computerized natural language interaction are examined. Different approaches were tested, and the most effective of these was found to involve a conditionally branched search of key words from among clusters of contextually synonymous words. This mode of man-machine interaction offers a multistage model for certain aspects of human verbal interaction. Possible ways of testing this model are suggested as well as uses for diagnosing certain cognitive dysfunctions, especially in children.<<ETX>>","PeriodicalId":291071,"journal":{"name":"Proceedings of the Symposium on the Engineering of Computer-Based Medical","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122261367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adaptive noise canceling techniques are utilized to obtain noise-canceled projections in the data-preprocessing stage. Because noise encountered in computerized tomography is signal-dependent, an adaptive predictor is preferred to a fixed-parameter filter. Noise cancellation is achieved because the decorrelation time for broadband noise is less than that of narrowband signals. Both the tapped delay line structure and the lattice have been studied for implementing the adaptive linear predictor. The idea of forward-backward processing is used for circumventing the large error in the initial part of the noise-canceled projection data. The reconstruction is then completed from noise-filtered projection data using the convolution back projection method. Simulation results demonstrating the efficacy of the proposed method are presented.<<ETX>>","PeriodicalId":291071,"journal":{"name":"Proceedings of the Symposium on the Engineering of Computer-Based Medical","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125970128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It represents declarative knowledge in an associative network, allows the attachment of arbitrary procedural knowledge, and is used by a problem-independent control algorithm. This framework is used to implement a complete system for the diagnostic evaluation of scintigraphic images of the heart. The input to the system is an image sequence which is first preprocessed and segmented to obtain the left ventricle and its sectors. The contours of the ventricle and the sectors are the basis for knowledge-based analysis of the images. Analysis proceeds from the contour segments via objects and their motions to diagnostic descriptions of the image sequence. Experiments show that the system successfully completes analysis, and in particular does not make wrong diagnostic suggestions.<<ETX>>","PeriodicalId":291071,"journal":{"name":"Proceedings of the Symposium on the Engineering of Computer-Based Medical","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131671801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To show how neural nets work, experiences in an experiment using them are described. The experiment involves using AI techniques to assist in the discovery of causal relationships between the variables existing in a large clinical trial database. A peripheral vascular disease database was used to acquire a feeling for the complexities involved in developing a distributed encoding scheme and to determine the computational resources required to train a neural net for the type of data used. By testing several models the effects of changes in the encoding scheme and the number of training iterations the system needed to predict the appropriate change needed could be determined. These results were compared to the information available from other analyses of the same data. The generative capabilities of the system were then tested by training it over one sample of cases and applying it to cases it had not encountered before. Some idea of the computational resources needed in terms of time and memory capacity was developed.<<ETX>>","PeriodicalId":291071,"journal":{"name":"Proceedings of the Symposium on the Engineering of Computer-Based Medical","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127638698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
