Application of the Simplex Method in Optimizing a Gradual Implementation in Credit Modalities (Aplicação do método Simplex na otimização de uma implementação gradual em modalidades de crédito)
type: item
description: https://zenodo.org/records/16516919 The article addresses the fictional case of the company AutoProvision. The main goal is to determine the best combination of clients across different credit modalities (Working Capital, Overdraft, Personal Loan, etc.) to maximize expected profit during an initial phase of gradual project implementation. For this, we use Linear Programming, modeling the problem with decision variables (number of clients per modality), an objective function (maximize total profit), and constraints (capital limits, total client capacity, demand per modality, and a minimum for diversification). The model was implemented in Python using the PuLP library and solved using the Simplex Method. The results define the optimal allocation of clients for each credit line in this first cycle, resulting in a data-driven action plan for the start of AutoProvision's operations, as well as serving as a basis for future analyses and adjustments as the business evolves. The work demonstrates the practical application of optimization tools in a business context, including visualization and analysis of the results.

title: IMAGE CLASSIFICATION FOR IDENTIFICATION OF DEEPFAKES GENERATED BY ARTIFICIAL INTELLIGENCE USING SELF-ATTENTION AND MACHINE LEARNING MODEL (CLASSIFICAÇÃO DE IMAGENS PARA IDENTIFICAÇÃO DE DEEPFAKES GERADAS POR INTELIGÊNCIA ARTIFICIAL UTILIZANDO MODELO DE AUTOATENÇÃO E APRENDIZADO DE MÁQUINA)
description: https://doi.org/10.5281/zenodo.15708576 Com o crescente uso de tecnologias de inteligência artificial (IA) para gerar conteúdos visuais, a necessidade de ferramentas eficazes para distinguir o real do sintético tornou-se indispensável. A disseminação de deepfakes e a manipulação de imagens representam ameaças significativas à integridade da informação e à segurança digital. Este trabalho desenvolveu e avaliou modelos de classificação de imagens para identificar conteúdos gerados por IA com alta precisão, empregando técnicas modernas de aprendizado de máquina e aprendizado profundo. Utilizamos uma base de dados composta por mais de 12 mil imagens, classificadas em conjuntos de treinamento, validação e teste. Diversos modelos foram explorados, incluindo KNN, PCA + SVM, Random Forest e arquiteturas avançadas baseadas em transformadores, como ViT e DeiT. No entanto, os melhores resultados foram alcançados com o modelo ResNet50, após a implementação de técnicas de regularização como dropout, L2 regularization e data augmentation, que mitigaram problemas de overfitting e garantiram uma maior capacidade de generalização do modelo. Os resultados mostraram que a ResNet50, com essas melhorias, alcançou uma acurácia de 97,90%, superando os modelos baseados em transformadores testados, como o DeiT e o ViT. Isso demonstra a eficácia das redes convolucionais, quando ajustadas corretamente, para capturar padrões sutis e características essenciais que distinguem imagens reais de deepfakes. Embora o modelo tenha apresentado um desempenho robusto, o campo da detecção de deepfakes permanece em constante evolução, demandando aprimoramentos contínuos. O aumento da diversidade dos conjuntos de dados e o desenvolvimento de modelos mais resistentes a manipulações adversárias são desafios importantes que precisam ser abordados. Este estudo reforça o potencial das redes convolucionais, combinadas com técnicas de regularização e pré-processamento, na detecção de conteúdos gerados por IA. Como…

title: Prediction Models Based on Players' Historical Data for Evaluating Competitive Balance in League of Legends Matches (Modelos de Previsão Baseados em Dados Históricos dos Jogadores para Avaliar do Equilíbrio Competitivo em Partidas de League of Legends)
description: https://doi.org/10.5281/zenodo.15702048 This study aims to investigate possible trends in the ranked queues of the game League of Legends, developing predictive models to evaluate the balance of matches based on players' historical data. The data was collected through the game's official API, including statistics such as KDA, gold per minute, vision score, damage per minute, and objectives achieved (towers, dragons, and barons). Different machine learning techniques, including Random Forest, Logistic Regression, and SVM, were implemented and compared, using Python for backend development and data processing. The models were evaluated using metrics such as accuracy, F1 Score, recall, and support. The Random Forest model showed the best performance during training, achieving 96% accuracy. However, when tested with live match data, its performance dropped significantly, with the best result reaching 48%. The confusion matrix revealed the models' limitations in capturing more complex nuances of the matches. Additionally, an analysis of the win-rate proportion between teams was conducted, contributing to a broader understanding of the factors influencing match balance. The results suggest that, although the selected attributes are relevant, they are insufficient to identify patterns indicating imbalance in matches. This evidence highlights the effectiveness of the matchmaking system and the impact of Matchmaking Rating (MMR) on maintaining balance in matches.

title: Investigation of Academic Performance in the Analysis and Systems Development Course in Brazil: Framework for Monitoring and Evaluating Grades (Framework for Analyzing the Patterns that Influence the Progress of Students in the Early Semesters of Systems Analysis and Development Courses in Brazil)
description: https://doi.org/10.5281/zenodo.15701706 The course in Analysis and Systems Development (ADS) is essential to meet the growing demand in the Information and Communication Technology (ICT) market in Brazil, which seeks qualified professionals to support digital transformation. Although salaries in the ICT sector are higher than the national average, Brazil faces challenges in meeting this demand due to the limited number of graduates annually from programs such as ADS. This study analyzes the academic performance of students in the ADS course, focusing on the factors that influence their academic progress, using grades obtained in specific subjects during the first two semesters of the course as the basis. The research was conducted at a private higher education institution, involving data from 160 enrolled students. Subjects such as "Algorithms" and "Programming Language," as well as "Information Technology" and "Systems Analysis," were analyzed, selected for their similar syllabi, allowing for performance analysis over two consecutive semesters. The results indicated that difficulties in the first semester, especially in fundamental subjects such as "Algorithms," affect performance in subsequent subjects, suggesting the existence of patterns in the flow of academic performance. Furthermore, it was observed that performance between subjects shows important relationships, indicating that poor performance in one subject can impact other areas. The categorization of performance profiles allowed for the identification of specific student groups that may benefit from support strategies, such as enhanced teaching, remedial activities, and personalized monitoring.

Aplicação de Técnicas de Machine Learning e Processamento de Imagens para a Identificação de Selos Indicativos de Excessos em Embalagens Alimentícias
type: item
description: https://doi.org/10.5281/zenodo.15700909 Este estudo investigou a viabilidade da aplicação de técnicas de Machine Learning e processamento de imagens em dois cenários distintos relacionados à análise de embalagens alimentícias. O estudo principal focou na detecção de selos de alerta (indicando excesso de gordura, açúcar ou sódio) utilizando uma base de dados própria com 92 imagens distintas coletadas pelas autoras em supermercados. Para o reconhecimento de padrões visuais, foram empregadas redes neurais convolucionais (CNNs), com o uso de data augmentation para aumentar a diversidade do conjunto de dados e aprimorar a robustez do modelo. Os resultados obtidos demonstraram uma acurácia de 0.83, com métricas de precisão (0.89), recall (0.89) e F1-score (0.89) para a detecção de selos em embalagens planas, como as de barras de chocolate. Antes do estudo principal, foi realizado um estudo experimental que visou a extração automática de informações nutricionais de embalagens, com o objetivo de transcrever essas informações para facilitar o acesso de pessoas com deficiência visual, analfabetos e crianças. A base de dados utilizada foi a OpenFoodFacts API. Para este estudo, foi empregado o método de Reconhecimento Óptico de Caracteres (OCR), com destaque para o uso da ferramenta Tesseract. Apesar de serem aplicadas técnicas de tratamento de imagem, como a redução de ruídos, sombras e curvaturas, foi identificado que, com o código utilizado, não era possível obter bons resultados em imagens que apresentassem sombras ou curvaturas. Essas condições adversas comprometeram o desempenho do OCR, dificultando a extração precisa do texto das embalagens. O estudo conclui que, embora o reconhecimento de texto em embalagens alimentícias exija melhorias adicionais no pré-processamento de imagens, a abordagem proposta para a detecção de selos apresenta-se promissora, com desempenho satisfatório e aplicabilidade prática no cenário analisado.

Use Of Predictive Recurring Neural Network Models In The Prediction Of Dengue Cases (Previsão de casos de dengue utilizando modelos preditivos derede neural recorrente - RNN)
type: item
description: https://doi.org/10.5281/zenodo.15699989 This research addresses the prediction of dengue outbreaks using statistical data, aiming to develop a predictive model that assists in the early identification of dengue outbreaks in the State of São Paulo. A quantitative approach was employed, utilizing statistical analysis techniques and mathematical models to process and interpret data collected from epidemiological and meteorological sources. Factors such as temperature, humidity, age, population, gender, waste collection, and access to treated water were analyzed, as well as the incidence of dengue cases in different regions of the State between the years 2010 and 2024. The methodology included the application of time series in predictive models developed using Recurrent Neural Networks (RNN) with three types of layers: Simple RNN, Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU). The results indicated that the combination of climatic variables and historical dengue data allows for the accurate prediction of new outbreaks. It was concluded that the application of statistical models in predicting dengue outbreaks can be a valuable tool for public health authorities, enabling the implementation of preventive and control measures more effectively and promptly, thus contributing to reducing the impact of dengue in affected communities.

title: Musical Plagiarism Detection: An Approach with Artificial Intelligence (Al) and Machine Learning (ML) (Detecção de plágio musical: uma abordagem com inteligência artificial (IA) e aprendizado de máquina (AM))
description: https://doi.org/10.5281/zenodo.15678650 This study explores the development of an automated system for detecting musical plagiarism, a journey intertwined with advanced signal processing techniques, machine learning (ML), and textual analysis. Each step, each note, reflects the complexity and sensitivity of the topic. Data collection, a cornerstone of this process, requires a robust, diverse, and dynamic database that embraces different musical genres, historical periods, and harmonic and melodic variations. As highlighted by Smith (1997), diversity in datasets is crucial to avoid biases in analysis and to enhance the models' generalization capacity. The system's architecture, designed to be modular and scalable, employs AWS services with the precision of a conductor: EC2 orchestrates model hosting, S3 stores data like valuable scores, and Lambda executes asynchronous processing. This structure not only supports massive data volumes but also enables real-time analysis and the addition of new features seamlessly. Every line of code respects the guidelines of the Copyright Law (Law 9,610/98), which allows the use of protected works for academic and research purposes. The initial results offer promising chords. The combination of MFCC and PCP, key tools in tonal analysis, proved powerful in identifying harmonic similarities with high accuracy. However, the system also hits a few dissonant notes: applying techniques like STFT and KNN to long-duration music reveals computational limitations, emphasizing the need for a more robust infrastructure and fine-tuned parameterization. Logan (2000) had already pointed out the value of MFCC in adapting audio analysis to human perception, and here, its impact resonates. Additionally, the system boldly expands its repertoire with added features. One of these is the classification of musical genres based on song lyrics, a task led by the Naive Bayes Multinomial and TF-IDF vectorization. Early performances show impressive results in c…

DEEP LEARNING TECHNIQUES APPLIED IN STOCK MARKET FORECASTS (TÉCNICAS DE DEEP LEARNING APLICADAS EM PREVISÕES NO MERCADO DE AÇÕES)
type: item
description: https://doi.org/10.5281/zenodo.15670699 The Brazilian stock market has proven to be very profitable in recent years, even in adverse scenarios. For example, in 2021, when many industries faced significant challenges such as economic crises and political instability, affecting a wide range of sectors, the market continued to attract investors, with some companies achieving impressive results and surpassing expectations. This growth reflects the importance of the stock market as one of the pillars of the Brazilian economy, being essential for the development of businesses of all sizes and sectors, from the largest corporations to small businesses. In times of crisis, the stock market offers opportunities for both investors and companies seeking to capitalize on their operations and expand their activities. Given the relevance of the stock market to the Brazilian economy, we aimed to analyze various factors that influence stock performance, such as economic policies and fluctuations in interest rates. To forecast stock prices for different companies, we collected historical stock price data along with economic indicators. This data was then processed and analyzed using time series models, classification and regression techniques. The time series models facilitated the identification of patterns over time, while the classification and regression techniques helped detect the key factors that influence price variations. With this combination of methods, it was possible to conduct a thorough analysis; now we present the results obtained from the application of each model.

type: item
description: DOI: 10.5281/zenodo.10732940 With the emergence, popularization and ease of consumption of generative Artificial Intelligences – AIs capable of generating content that does not yet exist, be it written, visual, among others – it has become necessary to create tools that can combat plagiarism and misuse of intellectual property. An example of this problem is a case that became extremely popular in which an image created by the generative AI Midjourney won a digital art competition (Oliveira, Pedro, 2022), raising several debates about it. This article aims to analyze the images of signatures, in order to reach a conclusion on the topic: is it possible to distinguish the handwriting of a human and an AI? To this end, the following techniques were used: SIFT (Scale-Invariant Feature Transform) to extract characteristics that distinguish the two types of signatures. The K-Means algorithm to group the data that will be transcribed into a histogram that will be consumed by the K-Neareast Neighbors (KNN) algorithm that will classify the data obtained. Using a base of original and artificially generated images of the painter's handwriting, Claude Monet - from the Impressionist art movement - this research aims to develop and conclude the possibility of differentiating a human handwriting from that generated by an AI algorithm based on the signature present in the work, through Machine Learning algorithm technologies.

Application to assist in the recognition and identification of lost pets using the Artificial Neural Networks technique
type: item
description: DOI: https://doi.org/10.5281/zenodo.10724842 O número de animais de estimação abandonados no Brasil aumentou significativamente entre 2018 e 2020, com um aumento de 126% no início da pandemia (IPB, 2022). Este estudo explora o impacto emocional do abandono em cães e a felicidade do reencontro com seus donos. Os cães sofrem de abandono, aguardando o regresso dos seus donos (Bradshaw, 2016). Este período de espera enfraquece-os, pois quebra a sua rotina e afecta o seu autocuidado. A perda de um animal de estimação pode ser comparada à perda de um ente querido. No Brasil, o processo de reencontro de animais de estimação com seus donos ainda é precário. Porém, quando o reencontro acontece, a felicidade é imensa para ambas as partes, melhorando a saúde física e mental. A conexão nesse momento transcende os sentidos da vida. Este trabalho tem como objetivo implementar uma ferramenta de reconhecimento de padrões utilizando técnicas de Inteligência Artificial (IA) para ajudar a identificar animais de estimação perdidos. A ferramenta utilizará algoritmos de reconhecimento de imagem e de aprendizagem automática para fazer corresponder os animais de estimação perdidos aos seus donos. A ferramenta será desenvolvida utilizando tecnologias de código aberto e será disponibilizada ao público gratuitamente. Os benefícios esperados da ferramenta incluem: Aumento das hipóteses de reunir os animais de estimação perdidos com os seus donos; Redução do stress e da ansiedade tanto para os animais de estimação como para os donos; Aumento da sensibilização para o problema do abandono de animais de estimação e, Incentivo à adoção de animais de estimação. O desenvolvimento desta ferramenta é um passo significativo para resolver o problema do abandono de animais de estimação no Brasil. Ao aproveitar o poder da IA, podemos ajudar a criar uma sociedade mais compassiva e responsável para todos os animais.

The Importance of Neural Networks in Aiding the Identification of Monkeypo
type: item
description: DOI 10.5281/zenodo.10713093 With the arrival of covid-19 and a global quarantine scenario, the use of technology in the healthcare sector has grown dramatically, and telemedicine has become a great resource for healthcare professionals and patients. It is estimated that demand for the service increased by 226% in the first two months of 2022, compared to the previous year. However, after the preventive measures and the decrease in cases and deaths, telemedicine has remained a great ally for its many benefits, such as the speed of care, less exposure to contagious diseases, and no travel costs. COVID-19 was not the only contagious disease during this pandemic period, while the focus of governments and people was on controlling and reducing covid-19 cases, other diseases were boosting their numbers, such as monkeypox. Shortly after the covid crisis, there was a huge increase in monkeypox, a disease caused by by the orthopoxvirus genus. It is a disease characterized by skin rashes and can be transmitted by physical contact and airborne droplets, so the patient also needs to be isolated so that there is no contagion. The focus of our study is the comparison between two neural networks, Resnet18 and Xception, in the context of image recognition, to identify symptoms on patients' skin. Notably, Resnet18 has emerged as the option with the best cost-benefit ratio. This choice provides convenience, speed, and safety, ensuring effectiveness in symptom identification without unnecessarily exposing the health condition.
