    Sierra, Christian Peña; Cutipa, Enrique Agreda; Wong, Lenis (Institute of Electrical and Electronics Engineers Inc, 2024-01-01)
    In the Peruvian financial sector, deficiencies persist in customer service training due to inadequate comprehension of work motivation and the absence of suitable incentives, reflective of concerns regarding skill shortages and operational inconsistencies among employees. This study proposes a gamification framework tailored to enhance the training of Customer Service advisors within financial entities, addressing the gap in specific training models for this crucial sector. Through analysis, design, and validation stages, the research scrutinizes existing methodologies and implements the framework within a financial Contact Center, yielding impressive results. Notably, a remarkable 85% reduction in training time (from 60 to 8.80 minutes) while maintaining consistent evaluation scores with a 1% increase, alongside a noteworthy 13% decrease in average evaluation duration, underscores the framework's efficacy. These findings emphasize its potential for continual enhancement in training practices, promoting heightened productivity, knowledge retention, and motivation among Customer Service advisors within the financial landscape.

  • Optimization model for healthcare processes using Process Mining

    Julca, Marice Aranza Regina Dorador; Cardenas, Angel Ruben L.; Armas-Aguirre, Jimmy; Mayorga, Santiago Aguirre (IEEE Computer Society, 2023-01-01)
    In this paper, we propose an optimization model for medical services processes to reduce waiting time using process mining. In medical services, there is a high percentage of dissatisfaction with medical care due to the processes related to appointment booking and waiting time for medical consultation. As a result, patients change medical services due to the urgency of the symptoms they suffer, generating distrust in health services in Peru. Through a medical information system, events of medical care processes are collected for analysis using the Celonis tool. The process mining discipline uses the discovery of the study process to identify existing bottlenecks in the process and violations that are included when monitoring process events. The proposed model is based on identifying the existing bottlenecks in the processes, which are appointment booking and office care, as these processes take an average of 135 minutes to execute, and this leads to patient dissatisfaction. The model is composed of 4 main phases: 1. Objectives definition and data processing phase; 2. For the validation of the proposal, a test scenario was defined in a Peruvian public health services organization (ESSALUD) in Satipo, Peru. Preliminary results show that the model reduces by 64% the average time corresponding to the medical consultation process and by 98% the appointment booking. Finally, optimization results increased by 45% and 46%, respectively.

  • Thermographic image processing analysis in a solar concentrator with hard C-means clustering

    Flores, Marco A.; Serrano, Fernando E.; Cadena, Carlos; Alvarez, Jose C. (Springer, 2023-09-01)
    Style transfer is a natural language processing generation task, it consists of substituting one given writing style for another one. In this work, we seek to perform informal-to-formal style transfers in the English language by using a style transfer model that takes advantage of the GPT-2. This process is shown in our web interface where the user input a informal message by text or voice. Our target audience are students and professionals in the need to improve the quality of their work by formalizing their texts. A style transfer is considered successful when the original semantic meaning of the message is preserved after the independent style has been replaced with a formal one with a high degree of grammatical correctness. This task is hindered by the scarcity of training and evaluation datasets alongside the lack of metrics. To accomplish this task, we opted to utilize OpenAI’s GPT-2 Transformer-based pre-trained model. To adapt the GPT-2 to our research, we fine-tuned the model with a parallel corpus containing informal text entries paired with the equivalent formal ones. We evaluate the fine-tuned model results with two specific metrics, formality and meaning preservation. To further fine-tune the model, we integrate a human-based feedback system where the user selects the best formal sentence out of the ones generated by the model. The resulting evaluations of our solution exhibit similar to improved scores in formality and meaning preservation to state-of-the-art approaches.

    Mazzarri Rodríguez, Carlos J.; Leyva Calle, Juan A.; Padilla, Alfredo Barrientos (International Institute of Informatics and Systemics, IIIS, 2023-01-01)
    Currently, continuous technological advancements are pervasive in society, enhancing various aspects of our lives, including entertainment, information, and communication. In this context, one of the primary domains that can benefit from these advancements is education. The constant technological developments must be applied to the educational system to keep pace with changes in our lifestyle. Augmented reality (AR) is an innovative technology that allows smartphones to combine the real environment with virtual objects. Through the device's accelerometer, gyroscope, and camera, AR places 3D models on the screen based on the user's movements, creating an interactive experience. This technology has the potential to improve the learning experience in schools, making teaching more dynamic and increasing student motivation and interest in subjects such as mathematics and sciences, among others. This paper proposes the creation of a mobile application with tools that will enable not only students but also teachers to visualize and interact with any 3D model related to school subjects, enhancing the learning process and making it more engaging for them. Additionally, teachers can add all the information they deem necessary to the page of each model to describe, explain, or highlight any relevant data for their class. The primary contribution of this study is that the system allows teachers to encapsulate knowledge into an organized learning unit, improving the learning experience for students. The impact of the application on learning was assessed through surveys administered to five high school teachers in the Metropolitan Area of Lima after they had tested the application.

    Barrientos, Alfredo; Ríos, Sergio A.; Oviedo, Johan D. (International Institute of Informatics and Systemics, IIIS, 2023-01-01)
    The video game industry has undergone one of the most significant transformations in recent times. This is reflected not only in the economic aspect but also in the increasing number of players who want to explore and interact in the world of video games in recent years. As for the Real-Time Strategy (RTS) genre, which reached its peak in the early 2000s, it did not continue to see the same trend in game development, and the population of active players has been declining [1]. The primary reason for this continuous decline is the competition from games in other genres such as First Person Shooter (FPS), Multiplayer Online Battle Arena (MOBA), and other genres with attractive characteristics that set them apart. In response to this, a solution is offered, which involves the development of a multiplayer RTS video game for Windows operating systems (PC), with the aim of generating greater interest among both beginner and expert players. This document will explain the procedures for the functional and aesthetic development of the video game, as well as validation regarding the user experience.

  • Predictive model to reduce the dropout rate of university students in Perú: Bayesian Networks vs. Decision Trees

    Medina, Erik Cevallos; Chunga, Claudio Barahona; Armas-Aguirre, Jimmy; Grandon, Elizabeth E. (IEEE Computer Society, 2020-06-01)
    This research proposes a prediction model that might help reducing the dropout rate of university students in Peru. For this, a three-phase predictive analysis model was designed which was combined with the stages proposed by the IBM SPSS Modeler methodology. Bayesian network techniques was compared with decision trees for their level of accuracy over other algorithms in an Educational Data Mining (EDM) scenario. Data were collected from 500 undergraduate students from a private university in Lima. The results indicate that Bayesian networks behave better than decision trees based on metrics of precision, accuracy, specificity, and error rate. Particularly, the accuracy of Bayesian networks reaches 67.10% while the accuracy for decision trees is 61.92% in the training sample for iteration with 8:2 rate. On the other hand, the variables athletic person (0.30%), own house (0.21%), and high school grades (0.13%) are the ones that contribute most to the prediction model for both Bayesian networks and decision trees.

  • DPF: App for diagnosing the psychological profile of a possible feminicide

    Ramirez, Ivette; Mauricio, David (Institute of Electrical and Electronics Engineers Inc., 2020-03-01)
    The most visible expression of violence against women is feminicide. The majority of feminicide cases are committed by the partner or former partner of the victim. This involves ongoing domestic abuses, threats or intimidation, sexual violence or situations in which women have less energy or resources than their partner. In addition, clinics, public hospitals or private health institutes have mental health evaluation processes, however, these flows are usually carried out in several sessions, which causes a delay in the diagnosis. In this article, a mobile application that supports psychologists or psychiatrists during the process of the psychological profile diagnosis is proposed. The system contains a questionnaire and psychological tests, in this way, based on the patient responses, indicators, and metrics, the psychological profile of the assailant is obtained as a result. The use of the system in 40 patients shows that the selection times and the psychological test qualification have improved, as well as the interpretation of the results and the total process of diagnosis, which, when obtained at opportune time, allows specialists to prevent the victim from a possible feminicide.
