ABSTRACT

BACKGROUND AND OBJECTIVE: Cervical cancer is one of the leading causes of women's death. Like any other disease, cervical cancer's early detection and treatment with the best possible medical advice are the paramount steps that should be taken to ensure the minimization of after-effects of contracting this disease. PaP smear images are one the most effective ways to detect the presence of such type of cancer. This article proposes a fuzzy distance-based ensemble approach composed of deep learning models for cervical cancer detection in PaP smear images. METHODS: We employ three transfer learning models for this task: Inception V3, MobileNet V2, and Inception ResNet V2, with additional layers to learn data-specific features. To aggregate the outcomes of these models, we propose a novel ensemble method based on the minimization of error values between the observed and the ground-truth. For samples with multiple predictions, we first take three distance measures, i.e., Euclidean, Manhattan (City-Block), and Cosine, for each class from their corresponding best possible solution. We then defuzzify these distance measures using the product rule to calculate the final predictions. RESULTS: In the current experiments, we have achieved 95.30%, 93.92%, and 96.44% respectively when Inception V3, MobileNet V2, and Inception ResNet V2 run individually. After applying the proposed ensemble technique, the performance reaches 96.96% which is higher than the individual models. CONCLUSION: Experimental outcomes on three publicly available datasets ensure that the proposed model presents competitive results compared to state-of-the-art methods. The proposed approach provides an end-to-end classification technique to detect cervical cancer from PaP smear images. This may help the medical professionals for better treatment of the cervical cancer. Thus increasing the overall efficiency in the whole testing process.

ABSTRACT

Comportamentos antissociais tornaram-se recorrentes no ambiente escolar e se manifestado por meio de agressões físicas, verbais e simbólicas. O objetivo deste estudo foi verificar o efeito de uma intervenção, fundamentada no atendimento das necessidades psicológicas básicas (NPB), nos comportamentos pró e antissociais em aulas de Educação Física escolar. Participaram deste estudo 45 alunos e 2 professores de educação Física (PEF) divididos em Grupo Controle (GC) e Grupo Intervenção (GI). Os alunos responderam o Questionário de Atitudes no Esporte (QAE-23) e uma entrevista semiestruturada nos momentos pré e pós intervenção. A intervenção consistiu em uma orientação semanal com o PEF do GI durante 10 semanas, com objetivo de realizar adaptações na aula a fim de levar ao cumprimento das NPB. Para verificar diferença entre os grupos, em relação às respostas do QAE-23, nos momentos pré e pós, foi utilizado o teste T de Student e adotado nível de significância 5%. Na análise qualitativa, as entrevistas foram gravadas, transcritas e, posteriormente, categorizadas e analisadas. Mediante análise dos relatos obtidos pela entrevista foi possível observar percepção do atendimento das NPB e redução de comportamentos antissociais. Contudo, não foi observada diferença estatisticamente significativa entre os grupos para as respostas do QAE-2. Conclui-se, por meio dos relatos obtidos na entrevista, que a intervenção pautada no cumprimento das NPB possibilitou um efeito positivo em relação à redução dos comportamentos antissociais, porém, os dados quantitativos sugerem que a duração do estudo pode ter sido um fator limitante de maior efeito em relação à ausência internalização dos comportamentos

The objective was to verify the effect of an intervention, based on the attendance of the basic psychological needs (NPB) and pro and antisocial behaviors in school physical education classes. Thirty-five students and two teachers of Physical Education, divided into Control Group (CG) and Intervention (GI) participated in this study. The students answered the Attitudes Questionnaire in Sport (QAE-23) and participated in a semi-structured interview in the pre-and post-intervention moments. The intervention was performed with the GI teacher for 10 weeks, aiming to promote NPB during class. The Student's t-test was used and adopted p <0.05. The interviews were categorized and analyzed. It was observed perception of NPB care and reduction of antisocial behaviors. It was concluded that intervention based on NPB compliance enabled a reduction of antisocial behavior, but the duration of the study may have been a limiting factor of greater effect in relation to the internalization of these behaviors
