Understanding and Personalising Clothing Recommendation for Women

In this paper, we introduce an approach for clothing personalized recommendation system that is able to recommend clothing items to women, according to their fashion styles and body types. Thus, our recommendation approach includes three main modules: one for automatically identifying the fashion style, the other for detecting body type, and the third is responsible for recommending clothing categories with models linked to clothing images. Thus, it allows the women to select appropriate clothing options, considering clothing categories that include: dresses, coats, tops, sweaters, jackets. We have evaluated our recommendation approach and preliminary results indicate that it significantly supports the users with adequate clothing choices.

An agent-based tutoring system for learning propositional logic using multiple linked representations

In this paper, we propose an agent-based ITS for learning propositional logic using two linked viewpoints and representations to address the problem on checking the validation of a given argument, articulating syntactic and semantic inference approaches. One motivation for this integration comes from the importance to involve students in two complementary viewpoints, permitting students to make connections between the two viewpoints involving different strategies, used in problem solving situations. Basically, the system works by placing students in a problem-solving situation and providing needed knowledge support based on his performance. We discuss the system and show its architecture and functionality, as well as its implementation details. Through scenarios with adequate coverage, we evaluate the value of the proposed approach and conclude that it is feasible and useful.

Study on Machine Learning Algorithms to Automatically Identifying Body Type for Clothing Model Recommendation

The task of automatically identify body type with high accuracy is still a relevant problem in clothing fashion settings. This paper addresses such problem, presenting a study on machine learning techniques applied to classify women’s body shapes, taking into account a small set of body attributes, in order to further find appropriate clothing models. Thus, we perform a comparative study on such techniques to evaluate the accuracy of four classifiers, aiming at selecting the best of them to be used for clothing model recommendation based on rules. Overall, in the conducted computational experiment, Random Forest and SVM methods had the best performance, but the other two had also very good results, demonstrating their effectiveness to automatically identifying body type, serving as a relevant information to be used in our rule-based system to provide clothing model recommendation.

A Knowledge-based Approach for Personalised Clothing Recommendation for Women.

Currently, recommendation system technology has been assumed as a promising approach to contribute to fashion domain in terms of electronic commerce. In this paper, we propose an approach for a clothing personalized recommendation system that is able to help the women to identify appropriate clothing categories together with models linked to clothing images, mainly based on their fashion styles and body types. To achieve this, besides an intelligent user interface, our recommendation approach deals with two main components: the user modeling and the clothing recommendation, which is responsible for recommending fashion clothing items to women. The user modeling is responsible for creating and updating the user model, including two main knowledge-based mechanisms: the first is responsible for automatically identifying the fashion style, and the second is responsible for detecting body type. We evaluated our recommendation approach and preliminary results indicate that it significantly supports the women with choices.

An Approach that Support Multiple Linked Representations Within an Intelligent Tutoring System for Helping Students to Develop Skills on Designing Digital Circuits

This paper proposes an approach that allows an exploration of three linked representations within a tutoring system for helping students in problem solving situations to develop skills on designing digital logic circuits. Specifically, we provide a learning environment by considering situations that essentially consist of mapping a logic expression into another equivalent. This environment can work on two basic situations: (i) the students are asked to solve problems, having the possibility to receive personalized assistance or (ii) the tutoring system resolves problems asked by students. The problems and solutions have to be specified in two symbolic representations: Boolean algebra or Propositional Logic, having each expression automatically mapped into its equivalent expression displayed in gate logic language. The tutoring system architecture is presented, as well as its aspects of implementation. The proposed and implemented approach to the tutoring system was evaluated through scenarios of problems with adequate coverage, demonstrating its feasibility.

An interactive learning environment for assisting students in solving problems on designing of logic digital circuits by using Multiple Representations

In this paper, we propose a Web-based interactive learning environment with a knowledge-based assistant for helping undergraduate students in solving problems on designing digital circuits, focusing the relationship between Boolean algebra and Digital Logic. Particularly, we have addressed problem solving situations that essentially consist of mapping a logic expression into another equivalent, for example, the task of simplifying digital circuits. To do that, we have considered to operate on two symbolic linked representations: Boolean Algebra and Logic, connecting these two representations to a visual one with logic gates. This integration comes from the importance to involve students in three equivalent representations, permitting them to make connections between them. The learning environment contains a knowledge-based assistant that works on a collection of scenarios with several associated problems, where the students are placed in a problem-solving situation. To each problem, there are pedagogical resources needed to provide the students with feedback and knowledge support based on their performance and identified needs. Furthermore, there is an adaptive mechanism that is responsible for how problems should be sequenced or ordered, and even we have designed a switcher mechanism, which permits the students to change from one to another representation. We evaluate our approach by using scenarios and conclude that the system is feasible.

O plagio no meio academico e uma tarefa dificil de ser controlada, devido o grande numero de trabalhos que sao feitos por uma vasta quantidade de alunos e tambem pelo excesso de tarefas dos professores e pelo pouco tempo que conseguem dedicar para o controle da qualidade e autenticidade dos trabalhos. Com isso, e importante contar com softwares que auxiliem no processo de verificacao de indicios de plagio, desta maneira o presente trabalho vislumbra desenvolver uma nova ferramenta de analise de indicios de plagio bem como aprimorar o metodo DIP – Detector de Indicios de Plagio para auxiliar o docente na verificacao da autenticidade dos trabalhos.A Neuropedagogia promove o confronto sucessivo e simultâneo entre concepcoes tacitas, crencas e valores normativos com esquemas inovadores, criando um espaco entropico e poetico no âmbito da experiencia humana.
