The machine translation system from Ka Tu language into Vietnamese in a restrict context contributed to solving the serious lack of information in aboriginal languages and can be expanded into other areas such as warming fire alarm, broadcasting policies and laws of the State, farming experience, animal husbandry, natural disaster prevetion...

{"title":"A Multi-point Interactive Method for Multi-objective Evolutionary Algorithms","authors":"Long Nguyen, L. Bui","doi":"10.1109/KSE.2012.30","DOIUrl":"https://doi.org/10.1109/KSE.2012.30","url":null,"abstract":"Many real-world optimization problems have more than one objective (and these objectives are often conflicting). In most cases, there is no single solution being optimized with regards to all objectives. Deal with such problems, Multi-Objective Evolutionary Algorithms (MOEAs) have shown a great potential. There has been a popular trend in getting suitable solutions and increasing the convergence of MOEAs, that is consideration of Decision Maker (DM) during the optimization process (interacting with DM) for checking, analyzing the results and giving the preference. In this paper, we propose an interactive method allowing DM to specify a set of reference points. It used a generic algorithm framework of MOEA/D, a widely-used and decomposition-based MOEA for demonstration of concept. Basically MOEA/D decomposes a multi-objective optimization problem into a number of different single-objective optimization sub-problems and defines neighborhood relations among these sub-problems. Then a population-based method is used to optimize these sub-problems simultaneously. Each sub-problem is optimized by using information mainly from its neighboring sub-problems. In MOEA/D an ideal point is used to choose neighbored solutions for each run. Instead of using a single point, we introduce an alternative to the set of reference points. There are several way to take into account the information of the region specified by the set of reference points; here we used the mean of this set (or we call the combined point). The combined point which represents for the set of reference points from DM is used either to replace or adjust the current ideal point obtained by MOEA/D. We carried out a case study on several test problems and obtained quite good results.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123785386","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}

These relations were obtained by investigating the variations of prosodic features in Vietnamese emotional speech in comparison with prosodic features of neutral speech. The analyses were performed on a multi-style emotional speech database which consisted of Vietnamese sentences uttered in different styles. Specifically, four emotional styles were considered: happiness, sadness, cold anger, and hot anger. Speech data in the neutral style were also collected, and prosodic differences of each style with respect to this neutral baseline were quantified. The acoustic features related to prosody which were investigated were fundamental frequency, power, and duration. According to the analysis results, for each speaker of the database, a set of prosodic variation coefficients was produced for each emotional style. This will help for bringing emotions into Vietnamese synthesized speech, making them more natural.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"456 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123875936","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}

In this paper we generalize and extend their concept learning method [1] for description logic-based information systems. We take attributes as basic elements of the language. Each attribute may be discrete or numeric. A Boolean attribute is treated as a concept name. This approach is more general and much more suitable for practical information systems based on description logic than the one of [1]. As further extensions we allow also data roles and the concept constructors \"functionality\" and \"unquantified number restrictions\". We formulate and prove an important theorem on basic selectors. We also provide new examples to illustrate our approach.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130062027","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}

Because of syntactic structure discrepancy between two languages, the translation output will not preserve the same word order as the source. When a sentence is long, it should be partitioned into several clauses and the word reordering in the translation should be done within clauses, not between clauses. In this paper, a rule-based technique is proposed to split long Vietnamese sentences based on linguistic information. We use splitting boundaries for translating sentences with two type of constrains: wall and zone. This method is useful for preserving word order and improving translation quality. We describe experiments on translation from Vietnamese to English, showing an improvement BLEU and NIST score.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130840171","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 proposes a method for generating accurate models of components in order to solve this issue in the context of the component-based systems. The key idea of this method is to generate minimal deterministic finite automata as the accurate models of the corresponding components. For this purpose, the proposed method first computes a set of traces as a regular language of a given component by executing all possible experiments over the alphabet of the component. This method then constructs a regular expression to represent this set. After that, a minimal deterministic finite automaton as an accurate model of the component is generated by applying the Thompson algorithm and some optimized activities. The generated models are useful for the existing model-based approaches, e.g., model checking and model-based testing in improving quality of component-based software. An implemented tool supporting the method and experimental results are also presented.","PeriodicalId":122680,"journal":{"name":"2012 Fourth International Conference on Knowledge and Systems Engineering","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131478798","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 requires a manual quality control step conducted by experts to remove bad samples or bad SNP sites. In this paper, we propose a maximum likelihood method to detect bad samples to improve the reliability of the results.
