Time Series Classification With Motifs And Characteristics

In the last years, there is a huge increase of interest in application of time series. Virtually all human endeavors create time-oriented data, and the Data Mining community has proposed a large number of approaches to analyze such data. One of the most common tasks in Data Mining is classification, in which each time series should be associated to a class. Empirical evidence has shown that the nearest neighbor rule is very effective to classify time series data. However, the nearest neighbor classifier is unable to provide any form of explanation. In this chapter we describe a novel method to induce classifiers from time series data. Our approach uses standard Machine Learning classifiers using motifs and characteristics as features. We show that our approach can be very effective for classification, providing higher accuracy for most of the data sets used in an empirical evaluation. In addition, when used with symbolic models, such as decision trees, our approach provides very compact decision rules, leveraging knowledge discovery from time series. We also show two case studies with real world medical data.© Springer-Verlag Berlin Heidelberg 2014.537125138Buhler, J., Tompa, M., Finding motifs using random projections (2002) Journal of ComputationalBiology, 9 (2), pp. 225-242Chiu, B., Keogh, E., Lonard, S., (2003) Probabilistic Discovery of Time Series Motifs, pp. 493-498. , In"Proceedings of the 9th International Conference on Knowledge Discovery and Data Mining, New York, USAFerreira, P.G., Azevedo, P.J., Silva, C.G., Brito, R.M.M., (2006) Mining Approximate Motifs in Time Series, 4265, pp. 89-101. , In:Todorovski, L., Lavrač, N., Jantke, K.P.

Evaluation Of The Force X Elongation Curves Dispersion Of Descending Colon Of Rats Using Boltzmann's Sigmoidal Model [avaliação Da Dispersão De Curvas Força X Elongação De Segmentos De Cólon Descendente De Ratos Por Meio Do Modelo Sigmoidal De Boltzmann]

Purpose: to evaluate the dispersion of Force x Elongation curves (FE) that represents the mechanical behavior of rat's colon. Materials and Methods: ten descending colon segments were submitted to the Total Energy of Rupture Test. Each curve generated by this test was fitted to Boltzmann model that correlates the values of force and elongation through the combination of the parameters A1, A2, x0 and dx. Then, for each parameter were calculated the mean, standard deviation and their correlations. Later, the resultant dispersion was determinated in the whole deformation process by an analysis that considers the correlations between the greatnesses based on the propagation of uncertainties law. The resultant dispersion was multiplied by a coverage factor, considering a normal distribution, to determinate an interval in which 95% of force values will be present. Results: the mean, standard deviation and correlation were determined. The resultant dispersion of force values was expanded drawing limits inside which FE curves will be for a confidence interval of 95%. Conclusion: this methodology will be possibly used to evaluate variables that act on the intestinal mechanical behavior.2915156Fagundes, J.J., (1990) Estudo comparativo da cicatrização de anastomoses cólicas realizadas com auxílio do bisturi laser de dióxido de carbono: Trabalho experimental em cães, , Tese dedoutorado - Faculdade de Ciências Médicas da Universidade Estadual de Campinas, Campinas, SPWu, F.C., Lee, H.D., Machado, R.B., Dalmás, S., Coy, C.S.R., Góes, J.R.N., Fagundes, J.J., Apresentação do teste energia total de ruptura para avaliação de material biológico com propriedade viscoelástico não-linear (2004) Acta Cir Bras, 19 (6). , [serial on-line], Nov - DezWu, F.C., (2003) Estudo dos efeitos de diferentes concentrações de oxigênio e da hiperoxigenação hiperbárica sobre anastomose cólica comprometida ou não pela isquemia: Trabalho experimental em ratos, , Tese de doutorado - Faculdade de Ciências Médicas da Universidade Estadual de Campinas, Campinas, SPHendriks, T., Mastboom, W.J.B., Healing of experimental intestinal anastomoses (1990) Diseases of the Colon & Rectum, 33, pp. 891-901Burin, E.L.K., Lee, H.D., Niz, M.A.K., Silva, M.C.C., Coy, C.S.R., Góes, J.R.N., Predição do Comportamento Mecânico de Segmentos de Cólon Descendente de Ratos por meio do Modelo Sigmoidal de Boltzmann (2007) 56° Congresso Brasileiro de Coloproctologia: Anais do 56° Congresso Brasileiro de Coloproctologia, , 2007CuritibaNiz, M.A.K., Burin, E.L.K., Wu, F.C., Lee, H.D., Nogueira, F.M.A., Fagundes, J.J., Góes, J.R.N., Utilização dos modelos matemáticos de Boltzmann, de Chapman e Logístico para o estudo do comportamento mecânico de segmentos de cólon descendente de ratos (2006) CBIS 2006: Anais do X Congresso Brasileiro de Informática em Saúde, , 2006FlorianópolisVoltolini, R.F., Metz, J., Machado, R.B., Lee, H.D., Wu, F.C., Fagundes, J.J., Góes, J.R.N., SABI 2.0: Um sistema para a realização de teste biomecânicos em material viscoelástico não linear (2003) Laptec2003: Proceedings of The 4th Congress of Logic Applied to Technology, , 2003MaríliaBurin, E.L.K., Niz, M.A.K., Lee, H.D., Nogueira, F.M.A., Fagundes, J.J., Góes, J.R.N., Wu, F.C., Aplicação do Modelo Sigmoidal de Boltzmann para o Ajuste das Curvas Força x Elongação de Cólon Descendente de Ratos obtidas por meio do Aplicativo SABI 2.0 (2006) WIM 2006: Anais do VI Workshop de Informática Médica, , 2006Vila Velhada Silva, G.R., Sobre o modelo catalítico reversível aplicado ao estudo da cinética epidemiológica da infecção chagásica.

Comparative Study Of Computacional Models Generated From Representations Of Colonoscopic Images: Normal Mucosal Tissues Vs Mucosal Tissues Of Colic Polyp [estudo Comparativo De Modelos Computacionais Gerados Sobre Representações De Imagens De Coloscopia: Tecido De Mucosa Normal Vs Tecido De Mucosa De Pólipo Cólico]

Purpose: to evaluate the predictive quality of computational models to differentiate colic tissues, based on Co-occorrurence Matrices (MC) representation of Coloscopic Images (IC). Materials and Methods: Image analysis and artificial intelligence methods were employed to construct computational models. Sixty seven IC images, containing polyp, were considered in this work, from which a part containing a polypus and another without it were collected given origin to 134 images. For each one of these, different MC were constructed considering five distance parameters (D = 1 to 5) and the extraction of 11 texture characteristics. With this representation, five computational models were generated based on decision trees. These models were evaluated using two techniques: (a) cross-validation and (b) contingency tables. Results: for the (a) analysis, the model with D = 3 presented the smaller average error (22.25% ± 11.85%). For the (b) analysis, models with D = 1 and 3 presented the best precision values. Conclusion: parameters D = 1 and 3 presented models with the best predictive qualities. Results showed that the constructed models were promising to be applied within decision making computational systems.2912329Karkanis, S., Galoussi, K., Maroulis, D., Classification of Endoscopic Images Based on Texture Spectrum.

Prototype System To Manage Data On Coloproctology Surgery

Objective: To develop a prototype system to manage data on coloproctology surgery, aiming at Data Quality (DQ) and the adoption of a DQ monitoring process, which is nonexistent in most biomedical systems. Methods: The construction of the prototype was separated into five steps: analysis of an existing system (legacy), the analysis of requirements and specifications for the new prototype, the development of the model, definition of technologies and the development of a prototype. Results: The analysis of the legacy system revealed several limitations and inconsistencies, which can result in problems concerning the DQ. Therefore, actions to prevent these problems are already being executed at the step of developing the prototype, such as the creation of interactive and more elaborate interfaces, the use of validation mechanisms on data fields and the proposal of a process to monitor inconsistencies and incompleteness in patients' data. Conclusion: The adoption of DQ mechanisms on system development results in building a reliable and consistent database, to assist tasks such as management, scientific research and future intelligent data analysis methods. Future work includes subjective evaluations of DQ indicating the adequacy of the prototype for the users' needs.314351361Valarini, R., Campos, F.G.C.M., Resultado do registro nacional brasileiro em vídeo-cirurgia colorretal em 2007 (2008) J Coloproctol, 28 (2), pp. 145-155Martins, J.F., Rocha, J.G., Miranda, E.F., Sartor, M.C., Steckert, J.S., Steckert, A.S., Análise da prevalência de entidades coloproctológicas nos pacientes idosos do serviço de coloproctologia de um Hospital Universitário (2009) J Coloproctol, 29 (2), pp. 145-157Torres, N.J.R., Souza, J.R.M.C.A., Santiago, R.R., Prudente, A.C.L., Cirurgias colorretais no Hospital Universitário da Universidade Federal de Sergipe: Três anos de criação do serviço de coloproctologia (série histórica) (2008) J Coloproctol, 28 (1), pp. 77-83Prudente, A.C.L., Torres, N.J.R., Santiago, R.R., Mariano, D.R., Vieira, F.M.C., Cirurgias proctológicas em 3 Anos de serviço de coloproctologia: Série histórica (2009) J Coloproctol, 29 (1), pp. 71-76Queiroz, F.L., Côrtes, M.G.W., Rocha, N.P., Alves, A.C., Freitas, A.H.A., Lacerda, F.A., Resultados do registro de cirurgias colorretais videolaparoscópicas realizadas no estado de Minas Gerais-Brasil de 1996 a 2009 (2010) J Coloproctol, 30 (1), pp. 61-67Oliveira, R.G., Faria, F.F., Lima, J.R.A.C.B., Rodrigues, F.G., Andrade, M.M.A., Gomes, D.M.B.M., Cirurgias êntero-colorretais abordagem cirúrgica de 129 pacientes do SUS no programa de pós-graduação Sensu Lato em coloproctologia (2010) J Coloproctol, 30 (3), pp. 333-343Han, J., Kamber, M., (2006) Data Mining: Concepts and Techniques, , 2nd ed.

Evaluation Of Models For The Recognition Of Hadwritten Digits In Medical Forms

Medicine has benefited widely from the use of computational techniques, which are often employed in the analysis of data generated in medical clinics. Among the computational techniques used in these analyses are those from Knowledge Discovery in Databases (KDD). In order to apply KDD techniques in the analysis of clinical data, it is often necessary to map them into an adequate structured format. This paper presents an extension in a methodology to map medical forms into structured datasets, in which a sub-system for handwritten digit recognition is added to the overall mapping system. © 2008 Springer-Verlag Berlin Heidelberg.5167 LNBI178181Maletzke, A.G., Lee, H.D., Zalewski, W., Edson, R.F.V., Matsubara, T., Coy, C.S.R., Fagundes, J.J., Chung, W.F., (2007) Mapeamento de informações médicas descritas em formulários para bases de dados estruturadas [in portuguese], pp. 1-10. , Brasil, ppTrier, O.D., Jain, A.K., Taxt, T., Feature extraction methods for character recognition - a survey (1996) Pattern Recognition, 29, pp. 641-662Heutte, L., Paquet, T., Moreau, J.-V., Lecourtier, Y., Olivier, C., A structural/ statistical feature based vector for handwritten character recognition (1998) Pattern Recognition Letters, 19, pp. 629-641Arica, N., Yarman-Vural, F., An overview of character recognition focused on offline handwriting (2001) IEEE Trans.
