The 2LRS aims to select a reduced number of rules from a previously generated rule base and a reduced number of conditions for each selected rule. The learning adapts the cores of the MFs maintaining the partitions strong. The proposed approach has been experimented on two real world regression problems and the results have been compared with those obtained by applying the same multi-objective evolutionary algorithm for learning concurrently rules and MF parameters. We show that our approach achieves the best trade-offs between interpretability and accuracy.","PeriodicalId":120918,"journal":{"name":"2011 IEEE 5th International Workshop on Genetic and Evolutionary Fuzzy Systems (GEFS)","volume":"14 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131879655","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}

Interpretability assessment is usually addressed by evaluating the complexity and/or readability of fuzzy rule-based systems. However, comprehensibility is usually not taken into account because it implies more cognitive aspects which are difficult to formalize and to deal with. In this work we show the importance of considering not only readability but also comprehensibility during the design process of fuzzy systems. We introduce the use of a novel index for evaluating comprehensibility in the context of a three-objective evolutionary framework for designing highly interpretable fuzzy rule-based classifiers. It is named as logical view index (LVI) and it is based on a semantic cointension approach. The proposed evolutionary algorithm consists of embedding the HILK (Highly Interpretable Linguistic Knowledge) fuzzy modeling methodology into the classical NSGA-II with the aim of maximizing accuracy, readability, and comprehensibility of the generated fuzzy rule-based classifiers. Our proposal is tested in the well-known PIMA benchmark problem which corresponds to a medical diagnosis problem where interpretability is a strong requirement.","PeriodicalId":120918,"journal":{"name":"2011 IEEE 5th International Workshop on Genetic and Evolutionary Fuzzy Systems (GEFS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125176042","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}

Studying handwriting, we perceive the existence of elementary and global perceptual codes. Gathering the elementary ones in a choice of constraints we obtain global ones, and to obtain different forms of handwriting, we proceed by a perceptual organization of them. So, we present a new fuzzy genetic system to improve handwriting segmentation via perceptual codes. This system is based on the Beta-elliptic model, uses the fuzzy set theory to detect the elementary perceptual codes (EPCs) and the genetic algorithms for the global perceptual ones (GPCs). To validate our new system, we use ADAB database. The obtained results show successful representations of handwritten script via perceptual codes.","PeriodicalId":120918,"journal":{"name":"2011 IEEE 5th International Workshop on Genetic and Evolutionary Fuzzy Systems (GEFS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114383919","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}

This paper first shows the time complexities associated with WA and WTA inference methods in Takagi-Sugeno fuzzy rule-based systems, also highlighting the strengths and the weaknesses of both approaches. Then it argues that using a hybrid of the two inference methods, namely the WTA during identification and the WA during the evaluation, allows advantaging of the strong points of the two methods, without inheriting most of their weakness. In particular, the hybrid formulation has a nice property which can be even mandatory in particular applications: it both guarantees that the TS system is continuous (provided that infinite support membership functions are used) and that it performs an approximate reasoning, by combining the conclusions of more than one rule. The interesting features of the hybrid method are demonstrated on a multiobjective genetic rule learning framework used for regression.","PeriodicalId":120918,"journal":{"name":"2011 IEEE 5th International Workshop on Genetic and Evolutionary Fuzzy Systems (GEFS)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131775044","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}

Varying customer demands, shorter lifecycles and changing fashion trends are amongst the factors that make accurate production planning important. Manufacturers strive to fulfil requirements such as on-time completion, short production lead time and effective allocation of job order to specific production lines. However, effective production planning is difficult to achieve because the apparel manufacturing environment is fuzzy and dynamic. This paper suggests the use of intelligent production planning algorithms, based on fuzzy set theory, genetic algorithms (GA) and multi-objective genetic algorithms (MOGA), to achieve optimal solutions for apparel production planning.","PeriodicalId":120918,"journal":{"name":"2011 IEEE 5th International Workshop on Genetic and Evolutionary Fuzzy Systems (GEFS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131094900","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 use of more optimization objectives to cover more aspects of the fuzzy model is very convenient, but also leads to a many-objective problem that is intractable with classical algorithms. This paper proposes three distinct categories of interpretability measures that can be used for optimization. Moreover, it introduces a new interpretability measure for fuzzy tuning. The proposed metric is implemented into a state-of-the-art algorithm that includes many-objectives techniques which allow the use of more objectives without substantial degradation. The new algorithm is tested in a set of real-world regression problems with successful results.","PeriodicalId":120918,"journal":{"name":"2011 IEEE 5th International Workshop on Genetic and Evolutionary Fuzzy Systems (GEFS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121639100","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 novelty of this research lies in exploring the composition of quantitative and temporal fuzzy itemsets and the approach of using a multi-objective evolutionary algorithm. This preliminary work presents the problem, a novel approach and promising results that will lead to future work. Results show the ability of NSGA-II to evolve target itemsets that have been augmented into synthetic datasets.
