Semi-supervised learning with concept drift using particle dynamics applied to network intrusion detection data

Concept drift, which refers to non stationary learning problems over time, has increasing importance in machine learning and data mining. Many concept drift applications require fast response, which means an algorithm must always be (re)trained with the latest available data. But the process of data labeling is usually expensive and/or time consuming when compared to acquisition of unlabeled data, thus usually only a small fraction of the incoming data may be effectively labeled. Semi-supervised learning methods may help in this scenario, as they use both labeled and unlabeled data in the training process. However, most of them are based on assumptions that the data is static. Therefore, semi-supervised learning with concept drifts is still an open challenging task in machine learning. Recently, a particle competition and cooperation approach has been developed to realize graph-based semi-supervised learning from static data. We have extend that approach to handle data streams and concept drift. The result is a passive algorithm which uses a single classifier approach, naturally adapted to concept changes without any explicit drift detection mechanism. It has built-in mechanisms that provide a natural way of learning from new data, gradually "forgetting" older knowledge as older data items are no longer useful for the classification of newer data items. The proposed algorithm is applied to the KDD Cup 1999 Data of network intrusion, showing its effectiveness.

Valores culturais e organizacionais em transformação: estudo sobre o Programa de Intercâmbio Social da Aiesec

Many young people have chosen go on exchange experiences, expecting to live in a context full of diversity, to know elements in the country they are visiting and also to develop themselves personally and professionally. Organizational and cultural values can be acquired or developed through these professional exchange experiences. This paper aimed to understand the vision of young people who went on the social exchange of AIESEC related to cultural and organizational values in the experience. AIESEC is a global and nonprofit organization formed by university students, with the objective of peace and the fulfillment of the humankind needs. Thus, professional exchanges are the main tool for achieving this goal. The study analyzes the experiences of 15 exchange students as well as the point of view of five managers of the organization in order to gain a broad perspective in relation to exchange experiences to understand how young people understand the concept of culture. The interview results suggest that in labor relations, autonomy and egalitarianism are values that go together, while the harmony could be observed by the fact that the projects deal with the issue of sustainability. Furthermore, responsibility, tolerance and collective were the human values that the exchange students developed the most, indicating that experience enables openness to live the diversity and to the intercultural dialogue in order to value local cultures of the visited countries

A concepção do aluno sobre o papel da educação física na escola após a experiência de acampante

Camping alloys the implementation of a broad variety of activities that involves many aspects of the corporal culture of movement. There is much more than fun in games and plays and that’s what we seek to include in the children’s daily routine. The Physical Education professional has as one of its duties to teach these elements, such as the knowledge related to the citizenship formation to its students. Therefore, the participation in camping can contribute to this formation, since the students have the chance to realize the amplitude of Physical Education and change their view on it, even at school. The aim of this research is to investigate after the camping experience, if the students change their conception on the Physical Education role at school. This study has used qualitative methodology consisting on interviews done prior and post the students camping experience at the school . Ten students of both gender, aged between 13 and 15 years old, were interviewed. It was used a script with semi-structured questions. As the main result it has found an unanimity among the students towards the importance of Physical Education: the responsibility for the health and it’s also arisen discussions on cooperation and respect. Although they recognize that the teacher does not discuss these values and attitudes; two students believe that to have changed their view towards school Physical Education after experiencing the activities proposed in the camping. Despite most of the students haven’t changed their concept on school Physical Education, they had the opportunity to see new activities and to think more carefully about the importance of Physical Education classes at school, an opportunity on building a more critical view on the discipline.

Tatuagem, unheimliche e identificação: desvelamentos

The tattoo is a social phenomenon found in all social strata, with broad inclusion in all age groups and their motivation is commonly related to aesthetic pleasure, beauty and interest in body art. These references, however, are insufficient to understand the B side of the experience: the nightmares, attempts to erase, the compulsion and the concern about stop tattooing. Something happens between the search of beauty and the execution of the tattoo, that drags out the person to the anguish dimension. In detailing this, the specificity of distress Unheimliche will serve as our guide and, in the epistemological function of uncovering, allow an approximation to the concept of identification. Reading of the concept, the identification function will appear and, with it, the uncovering of the infinite pulse of desiring, when the object wants to talk,represent itself and manifest.The tattoos psychic function in the neurosis is the same for each step every morning: find the object and with this North, calibrate the compass of neurosis.

Esthetic and function improvement by direct composite resins and biomimetic concept

Aim: This case report describe a resin layering restorative technique based on biomimetic concept to improve esthetics in a patient with dental defects that affected both enamel and dentin in anterior teeth. Background: Severe structural defect in anterior teeth compromises esthetics and it is a high challenge to become the defect imperceptible after the restoration. Case description: A clinical sequence of applying different composite resin layers allowed the reproduction of the interaction between hard dental tissues and the restorative material. Conclusion: This technique achieved a satisfactory final esthetic outcome, preserving sound teeth structure and at same time, improved the quality of life of the young patient. Clinical significance: The utilization of the biomimetic concept to increase a disharmonic smile with dental defects is based in a conservative approach, which reached a satisfactory and esthetic outcome.

Foucault's heraclitism and the concept of history

Deleuze states that Foucault would have created a new relationship between men and history, a relationship other than that established by the philosophers of history. In order to specify the steps Foucault took to accomplish this invention, I shall support, according to Deleuze, Foucault s Heraclitism as the basis for a genuine Foucaultian concept of history. After outlining the risks taken by Foucault s concept of history, I observe this concept at work through the three periods that perform his thought: Archeology, Genealogy and Aesthetics of Existence. The main characters that embody his concept of history through these periods are: a) the discontinuous profile of history; b) the denaturalization of would-be unhistorical objects; c) the historical dimension of body; d) the eddies of subjectivation in history. We shall focus our inspection on the turn made along Foucault s work when he takes into a new account the theme of subjectivity, mostly in the last two volumes of the History of Sexuality. Thus, our attention turns to the subjectivity defined as a process, in order to investigate individual identity as the result of history.

The role of the state in health public policies: an overview of the debate on the concept of State and the Brazilian case

This article is the result of a narrative literature review. The objective is to show the development of an overview on the ideological debate on the design of state health policies. We argue that the role of the state in the development of health policy, even under the pressure of the global market, may create alternatives to promote and drive economic and social development, meaning they are not subject to economic constraints imposed by the liberal ideal of market. Here is a part of a theoretical discussion about the construction and presence of the State in Latin America, particularly in Brazil. We take the approaches of the Marxist tradition and liberal to the issue as reference. This discussion allows us to understand the historical role of the state in the maintenance of social policies, specifically health, is an alternative to public control eases the intense capital mobility promoted by economic globalization. In this sense, the theme makes the Brazilian health an important issue of social sciences, why is the historicity of the construction of the Brazilian health system, as a public policy that can mirror the actual reconstruction of the institutional framework of the Brazilian state with the establishment instances of negotiation between the various spheres of power that strengthen the state in this process of democratization of Brazilian society.

Concept design for a RFID enabled student workbook

In this paper, the concept for a radio frequency identification (RFID) enabled student workbook is discussed and a prototype system developed. The workbook is a question-answer notebook in traditional paper format in which hand written solutions to student assignments are written. An embedded RFID tag in the workbook is then used for the student to store his/her solution to the attempted assignment questions at home. On entry to the classroom and once the questions have been attempted, an RFID reader in the classroom will retrieve the answers from the workbook, automatically collate the results and instantly provide a summary of these results for the individual student and the class as a whole. If problems are highlighted, the teacher can then investigate issues with individual students and review the answers provided in the workbook.

Prevalence and possible risk factors of peri-implantitis: a concept review

The purpose of this review is to estimate the prevalence of peri-implantitis, as well as to determine possible risk factors associated with its development in patients treated with oral implants. Although implant therapy has been identified as a successful and predictable treatment for partially and fully edentulous patients, complications and failures can occur. Peri-implantitis is considered a biologic complication that results in bone loss around implants and may lead to implant treatment failure. A great variation has been observed in the literature regarding the prevalence of peri-implantitis according to the diagnostic criteria used to define peri-implantitis. The prevalence ranges from 4.7 to 43% at implant level, and from 8.9 to > 56% at patient level. Many risk factors that may lead to the establishment and progression of peri-implantitis have been suggested. There is strong evidence that presence and history of periodontitis are potential risk factors for peri-implantitis. Cigarette smoking has not yet been conclusively established as a risk factor for peri-implantitis, although extra care should be taken with dental implant in smokers. Other risk factors, such as diabetes, genetic traits, implant surface roughness and presence of keratinized mucosa still require further investigation. Peri-implantitis is not an uncommon complication following implant therapy. A higher prevalence of peri-implantitis has been identified for patients with presence or history of periodontal disease and for smokers. Until now, a true risk factor for peri-implantitis has not been established. Supportive maintenance program is essential for the long-term success of treatments with oral implants. The knowledge of the real impact of peri-implantitis on the outcome of treatments with oral implants as well as the identification of risk factors associated to this inflammatory condition are essential for the development of supportive maintenance programs and the establishment of prevention protocols.
