The trajectory of the first two formants, F1 and F2, is treated in a series of coordinate pairs that are mapped from the F1F2 plane into a two-dimensional plane of \"coefficients\". These coefficients are multipliers of two empirically-based orthogonal basis vectors which, when added to a neutral vowel area function, will produce a new area function with the desired locations of F1 and F2. Thus, area functions and voice parameters extracted at appropriate time intervals can be fed into a speech simulation model to recreate the original speech. A transformation of the speech can also be imposed by manipulating the area function and voice characteristics prior to the recreation of speech by simulation. The model has initially been developed for vowel-like speech utterances but the effect of consonants on the F1F2 trajectory is also briefly addressed.","PeriodicalId":437491,"journal":{"name":"Proceedings IEEE International Joint Symposia on Intelligence and Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127862029","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}

Recently, as the number of known protein structure are increasing steeply, automatic classification is highly required. This paper presents a new method of classification of protein folds based on the structural similarities between a pair of proteins from the viewpoint of the secondary structural elements. The similarity can be evaluated through the structural transformation from one protein to the other, which is composed of a set of predefined primitive operations. Since the similarity is scored with the total cost of the transformation, the method requires no threshold value. The effectiveness of the method was empirically demonstrated through the experiments using the data in the Brookhaven Protein Data Bank.","PeriodicalId":437491,"journal":{"name":"Proceedings IEEE International Joint Symposia on Intelligence and Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132759188","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}

The ANFIS controller, which enhances Sugeno fuzzy controller with self-learning capability from adaptive network, can combine the qualitative knowledge in fuzzy rules and be fine-tuned by online learning. The effectiveness of the proposed ANFIS joint control was verified through a 5-link biped robot simulation. We demonstrated that the designed hierarchical control system can use the experimental input-output data pairs for the biped robot learning and walking with dynamic balance. It is also shown that the further online self-learning capability of the ANFIS controller can markedly improve the dynamic walking performance of the biped robot.","PeriodicalId":437491,"journal":{"name":"Proceedings IEEE International Joint Symposia on Intelligence and Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116559713","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}

ACO performs local improvement by restricting the crossover range in adaptive way. This approach is based on bias value which restrict the location of crossover point. Bias value is computed by the fitness function value performance ratio, and the number of generations. As generations progress, the portion of chromosome to apply ACO becomes much smaller. ACO scheme can reduce the computation complexity and escape from getting stuck local optimum and also by maintaining diversity if can maintain the balance between exploration and exploitation. Several experiments have been carried our to compare the performance of adaptive scheme and standard scheme. Compared to simple GA, the proposed method is faster and more accurate in finding global optimum.","PeriodicalId":437491,"journal":{"name":"Proceedings IEEE International Joint Symposia on Intelligence and Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130201702","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}

One of the most difficult aspects of instrument fault diagnosis is developing an appropriate rule base for the expert network. Beginning with an initial set of rules given by experts, a more accurate representation of the reasoning process can be found using example data. A methodology for determining alternate paths of reasoning and incorporating them into the expert network is presented. Our technique presupposes interaction and cooperation with the expert, and is intended to be used with the assistance of the expert to incorporate knowledge discovered from the data into the intelligent diagnosis tool. Tests of this methodology are conducted within the problem domain of fault diagnosis for gas chromatography. Performance statistics indicate the efficacy of automating the introduction of alternate path reasoning into the diagnostic reasoning system.","PeriodicalId":437491,"journal":{"name":"Proceedings IEEE International Joint Symposia on Intelligence and Systems","volume":"79 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131175337","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 represent the knowledge, frame base (graph) knowledge representation has been chosen.

The challenge of developing an adaptive knowledge base depends on how to evolve the knowledge (adaptivity) and how to control the evolution (maintain the quality of the knowledge).
