It is common for general purpose ASR systems to fail in certain applications that use a domain specific language. Different strategies have been used to reduce the error, such as providing a context that modifies the language model and post-processing correction methods. This article explores the use of an evolutionary process to generate an optimized context for a specific application domain, as well as different correction techniques based on phonetic distance metrics. The results show the viability of a genetic algorithm as a tool for context optimization, which added to a post-processing correction based on phonetic representations is able to reduce the errors on the recognized speech.","PeriodicalId":220522,"journal":{"name":"Res.

Swarm robotics is inspired by the behavior of social animals for the coordination of a large number of low cost and insufficient robots that in performing a task requires collaboration. The behavior in a swarm of robots can be manipulated by changing the parameters of repulsion, attraction, orientation and influence (RAOI). In the case of repulsion, attraction and orientation modify the basic behavior of the swarm cre-ating functional groups of robots keeping them close or dispersed, even forming chains. While the influence parameter is associated with specific stimuli to guide the swarm to perform simple tasks. To demonstrate this, a simulation platform presents the impact of these parameters in a swarm of builder robots considering a task of transporting materials.","PeriodicalId":220522,"journal":{"name":"Res.

Boredom, stress and happy –learn-related emotions– are included in physiological signals datasets, but not in Facial Expression Recognition (FER) datasets. In addition to this, Galvanic Skin Response (GSR) signal is the most representative data for emotions classification. This paper presents a technique to generate a dataset of facial expressions and physiological signals of spontaneous and acted learnrelated emotions –boredom, stress, happy and neutral state– presented during video stimuli and face acting. We conducted an experiment with 22 participants (Mexicans); a dataset of 1,840 facial expressions images and 1,584 GSR registers were generated. A Convolutional Neural Network (CNN) model was trained with the facial expression dataset, then statistical analysis was performed with the GSR dataset. MobileNet’s CNN reached an overall accuracy of 94.36% in a confusion matrix, but the accuracy decreased to 28% for non-trained external images. The statistical results of GSR with significant differences in confused emotions are discussed.","PeriodicalId":220522,"journal":{"name":"Res. Comput.

This work presents an evaluation of the predictive techniques decision trees using CART algorithm, Na¨ıve Bayes Classifier, Gradient Boosting Machine and Support Vector Machine for predicting whether a student will successfully complete a programming course or not. Factors considered for prediction were university-entrance and personal criteria like entrance age, gender, scholarship, high school GPA, mark in admission exam and other related with student’s performance in a pre-requisite introductory programming course. The predicted variable takes two values, ‘Approved’ or ‘Not Approved’, and the data record contains an unbalanced portion of the class ’Approved’. For the analysis were considered two data sets, unbalanced and balanced. Evaluation of algorithms was performed considering the concepts of accuracy and ROC area. Results show that accuracy is bigger for the unbalanced data set, but its ROC area was very poor. Using the balanced data set, results were more reliable because accuracy and ROC area are closer. Best results were obtained with Na¨ıve Bayes and Support Vector Machine algorithms. The most important factor in the prediction was whether a student had a scholarship or not.","PeriodicalId":220522,"journal":{"name":"Res. Comput.

This paper presents a methodological proposal for automatic identification of emotions in educational environments using machine learning algorithms and physiological and behavioral signal acquisition technologies to identify relations between emotions and learning. Four of the main learning-centered emotions are considered [1]: engagement, boredom, confusion and frustration. It is proposed to make a fusion of data from two physiological and behavioral signal acquisition technologies with the objective of achieving the identification of emotions in the most precise manner. Therefore, considering the stages of the proposed methodology, the first of them is presented and the design of the experiment that will be executed for data collection. The development of an appropriate database with elements belonging to a learning environment for the study of emotions is an essential task.","PeriodicalId":220522,"journal":{"name":"Res. Comput.
