Estudo da variação da entropia de Shannon no jogo de xadrez a partir dos conceitos de teoria da informação
(Universidade Federal de São Carlos, 2024-02-15)
Information Theory is a branch of science that quantifies information and its communication processes, and has at its core the reformulation of the fundamental concept of entropy. Shannon's entropy reflects the measure of ...
Seleção estatística de árvores de contexto
(Universidade Federal de São Carlos, 2024-01-22)
Context trees are models that parsimoniously generalize Markovian models. These models were introduced by Jorma Rissanen in 1983, as an efficient tool in Information Theory. Since then, these models have been widely used ...
Classificação binária de dados financeiros em problemas com classes desbalanceadas
(Universidade Federal de São Carlos, 2024-01-29)
In order to mitigate the risks and uncertainties associated with credit granting, financial institutions are constantly exploring methods to enhance the credit evaluation system. In the same context, the growth in credit ...
Panorama sobre a análise das propriedades mecânicas de pellets de diferentes biomassas
(Universidade Federal de São Carlos, 2024-02-22)
Biomass is considered a more sustainable energy production option than fossil fuels. However, although it has a lot of potential, its intrinsic characteristics, such as its low energy density, make its widespread use more ...
Análise e previsão de séries temporais via Facebook Prophet
(Universidade Federal de São Carlos, 2024-01-29)
Forecasting is an estimate or projection of what may happen in the future based on information and data available from the past and present. In other words, it is an attempt to make an informed guess about what is likely ...
Utilização de algoritmos de classificação para diagnóstico de diabetes
(Universidade Federal de São Carlos, 2024-02-15)
The undergraduate thesis consists of the study of binary classification algorithms for diagnosing diabetes based on clinical data and physical activity data. For this purpose, we will accomplish a statistical and conceptual ...
Condutividade térmica de concretos com nanosílica
(Universidade Federal de São Carlos, 2020-12-16)
Nowadays, in Brazil, most buildings are dependent on high electricity consumption, a consequence of often disregarding strategies for thermal performance and energy efficiency of the built environment. In this context, ...
Estimação, seleção e predição de redes de neurônios estocásticos com memória de alcance variável
(Universidade Federal de São Carlos, 2024-02-02)
The nervous system is subjected to various sources of noise. Neuronal activity recordings reveal that part of this noise is due to electrical firings occurring spontaneously and irregularly, with variations even when the ...
Modelo de classificação para dados desbalanceados: método SMOTE e variantes
(Universidade Federal de São Carlos, 2024-01-29)
Often, in classification models, we encounter databases that have highly imbalanced classes, such as: rare disease diagnostic data, manufacturing defects, fraudulent transactions, etc. Training a model on a dataset with ...
Dimensionamento de um evaporador de vinhaça do tipo névoa turbulenta
(Universidade Federal de São Carlos, 2024-01-22)
The study analyses evaporation as a sustainable strategy for vinasse disposal, a subproduct of sugarcane ethanol production. The research aims to establish the sizing of a turbulent mist evaporator with a water evaporation ...
