Examples of such applications are related to bioinformatics, e-commerce, and sensor data. Regarding classification by means of decision trees, some efficient approaches have been proposed, which are centralized and based on restructuring the decision tree using new instances. However, there are some issues. First, most proposed approaches require that new instances are fully labeled. Second, in some environments, the agent in charge of the classification task cannot re-induce the classifier or restructure the decision tree each time it observes a new instance. Moreover, because this agent does not see the whole dataset, the induced classifier is not likely to be very accurate unless information is exchanged among the agents that are, each, in charge of pieces of the data. Thus, a decrease in accuracy may occur because attributes and classes may be misrepresented in the training dataset used so far. Instead of re-inducing the classification model with arbitrary frequency in a centralized way, this paper proposes an approach based on reinforcement learning that allows agents to go on using the existing classifier as basis for some exploration in the space of possible classifications. We use a quality assessment of the learned model in order to let each agent decide when it is time to get a new model, either by borrowing it from another agent, or by inducing a new classifier. Results using UCI datasets with various characteristics show that this method can be used as a compromise between costly methods for re-inducing the classifier at all times, and using only a static and centralized classification model.","PeriodicalId":114295,"journal":{"name":"2013 IEEE Symposium on Intelligent Agents (IA)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128891587","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 particular the functions that are used to estimate delay from volume of vehicles do not allow the representation of the phenomenon of congestion spillback. In some cases one needs to understand and analyze microscopic properties associated to how travelers adjust to the conditions they encounter. This, on its turn, leads to dynamic environments that are difficult to analyze with conventional tools. This paper presents an agent-based simulation of route choice under different conditions of demand generation, number, and types of driver agents. We consider more sophisticated drivers' behaviors such as en-route decision-making. Besides, they may be equipped with vehicle-to-vehicle communication. We discuss the effects of the use of: various ratio demand/capacity, demand generation, information exchange, and re-planning strategies. The use of an agent-based approach allows the analysis of different classes of agents, thus departing from the investigation of population-wide metrics only. The main conclusion is that for travelers whose trips are long, there is a benefit of using communication and replan en-route, depending on the demand. However, in general, having imperfect information is advantageous, especially from the whole system perspective.","PeriodicalId":114295,"journal":{"name":"2013 IEEE Symposium on Intelligent Agents (IA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132125595","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}

However, for an intelligent agent to be fully autonomous and adaptive, all aspects of intelligent processing from perception to action must be engaged and integrated. To build such an all-encompassing system is a formidable task. We propose that a good approach is to first identify the necessary intelligent computational structures and processes for dealing with a suitably designed micro-environment so that they are tractable. The challenge for computational intelligence is then to uncover general principles leading to general computational structures and processes that can deal with the micro-environment and that are also scalable to deal with more complex and real-world environments. Neuroscience research revealed that there are indeed such scalable general mechanisms in the brain and this is reviewed to provide inspirations for the building of artificial systems. A suitable micro-environment for this purpose must consist of a minimal set of features necessary to engage the various intelligent processes from that of the perceptual to that of the attentional, memory, affective, conceptual, planning, action, and learning. The micro-environment benchmark we propose here consists of an internal environment including the affective states of the intelligent agent as well as an external environment that is dynamic and in which activities of and interactions between objects can take place to engage the intelligent agent in all the intelligent processes described above.","PeriodicalId":114295,"journal":{"name":"2013 IEEE Symposium on Intelligent Agents (IA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114487355","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 provides the means for generating scenarios with different dimensions and characteristics, ensuring the representation of real and adapted markets, and their participating entities. The scenarios generator module enhances the MASCEM (Multi-Agent Simulator of Competitive Electricity Markets) simulator, endowing a more effective tool for decision support. The achievements from the implementation of the proposed module enables researchers and electricity markets' participating entities to analyze data, create real scenarios and make experiments with them. On the other hand, applying knowledge discovery techniques to real data also allows the improvement of MASCEM agents' profiles and strategies resulting in a better representation of real market players' behavior.

In fact, both Web 2.0 and Enterprise 2.0 applications have changed the knowledge sharing paradigm, and have introduced enabling features to foster information flow among users. Nevertheless, the availability of large amount of information targeted to human employment highlights reusing, reasoning and exploitation of available knowledge. Emerging Semantic Web technologies enable to codify information in a machine understandable way. Therefore, the latest web development trend is devoted to combine Web 2.0 features with semantic technologies (e.g. semantic tagging, semantic wiki). This scenario raises new requirements in terms of knowledge base extraction, update and maintenance. To this end, this work defines an ontology-based knowledge management platform that integrates methodologies aimed at supporting the life cycle of large and heterogeneous enterprise's knowledge bases. In particular, the defined architecture relies on hybrid methodologies which apply computational intelligence techniques and Semantic Web technologies to support Knowledge Extraction, Ontology Matching and Ontology Merging.","PeriodicalId":114295,"journal":{"name":"2013 IEEE Symposium on Intelligent Agents (IA)","volume":"162 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126414959","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}
