Project Concept

SoiLIA - Inteligência artificial a serviço da segurança alimentar e da recuperação ambiental.

Plataforma de inteligência artificial voltada ao combate da insegurança alimentar e à recuperação ambiental.

Ao oferecer recomendações personalizadas de manejo sustentável a produtores rurais, o projeto busca:

 

  1. Aumentar a resiliência da produção de alimentos
  2. Reduzir a degradação do solo
  3. Diminuir os impactos climáticos da agricultura convencional

Promovendo, assim, um ciclo mais saudável entre campo, meio ambiente e sociedade.

Luiz Fernando Brasão Fonseca Team Lead RSVP Approved

Machine Learning Engineer at Ubivis LTDA
Responsável pelo desenvolvimento do Estágio 02 (Diagnóstico, Recomendação e Restauração), orquestrando o estágio que transforma dados edafoclimáticos em inteligência agronômica. Implementou a Vertente de Diagnóstico utilizando redução dimensional (PCA) e seleção de Minimum Data Set (MDS) para formular o Soil Fertility Index (SFI) e quantificar déficits via Nutrient Gap Score (NGS). Desenvolveu os modelos baseados em Random Forest para classificação de fertilidade e recomendação multi-classe (22 culturas) a partir de uma estratégia de enriquecimento de features (8-dim). Idealizou o sistema de Restauração de Solo (Crop Impact Matrix e Restoration Score) e a função de fusão configurável que equaciona produtividade e regeneração. Por fim, integrou a camada de Explicabilidade (XAI) com SHAP (global) e LIME (local), garantindo a transparência das predições e validando a robustez da arquitetura por meio de testes de estresse
My interest in Machine Learning began in high school, when I started exploring Python, statistics, and data analysis. This led me to earn the IBM Professional Data Science Certification in 2023. I am currently pursuing a B.Sc. in Computer Science at PUCPR. From 2024 to 2025, I conducted undergraduate research on unsupervised representation learning with Autoencoders, improving cross-domain generalization for kidney stone detection in medical imaging. Currently, my research focuses on Vision Transformers for digital pathology, especially tumor and leprosy classification in histopathology images. I am also co-author of an international paper presented at IEEE SMC 2025 on federated learning for kidney stone detection, and was Technical Lead of the winning team at Renault Transformation Day.
I am interested in connecting with professionals in industrial, financial, and legal sectors to better understand operational challenges and identify opportunities for ML-driven automation. In Brazil, these areas still rely heavily on manual processes, creating strong potential for data-driven solutions. I am also interested in learning how to optimize complex ML models and architectures to run efficiently on IoT and embedded devices with minimal computational resources.
I work on applied and research-driven ML systems across industrial and medical domains, specializing in Computer Vision. My work includes predictive maintenance models for 3-phase motors using electrical current analysis and harmonic decomposition. In research, I previously optimized Autoencoder based models for cross-domain medical imaging tasks. Currently, I investigate Vision Transformers for digital pathology and histopathological image analysis.

Research at PUCPR
Responsável pelo desenvolvimento completo do Estágio 01 (Detecção por Imagem de Drone), incluindo a arquitetura CNN Multistream (streams RGB + NIR com late fusion), extração de máscara de solo via NDVI, e o pipeline de 26 features cromáticas do solo (CIELAB, LBP e índices espectrais). Também implementou a função de perda dual-task (CrossEntropy + MSE), o loop de treinamento com early stopping, e o contrato de interface padronizado que conecta as saídas do Estágio 01 aos estágios seguintes. Contribuiu ainda no design geral da solução e nas decisões de arquitetura do pipeline.
I was born in Paraná, Brazil, but spent most of my life in Rondônia. Passionate about science and technology, I decided in high school to pursue Computer Science and moved away from my family to study at PUCPR. During my studies, I developed a strong interest in Artificial Intelligence and Machine Learning, working on research projects as a PIBIC scholar, participating in programming competitions with PUCPR’s women’s team, and contributing to university technology initiatives. I am currently pursuing my master’s alongside my undergraduate degree through the PIBIC Master program with a full scholarship.
Machine Learning and Artificial Intelligence in general, including deep learning, data-driven systems, and model interpretability. I’m interested in solving complex problems using technology and collaborating on innovative projects that apply ML to real-world challenges. I enjoy both research-oriented work and hands-on development, especially in environments that encourage experimentation and creative problem solving.
I’m currently pursuing a master’s degree alongside my undergraduate studies through the PIBIC Master program at PUCPR. My research explores how SHAP-based Explainable AI can be integrated with Symbolic AI to make deep learning models more interpretable, particularly for medical applications.

Analista de Qualidade de Software at Telefônica Brasil (Vivo)
Responsável pela revisão geral do projeto, garantindo a qualidade e coerência entre os aspectos técnicos e de produto. Atuou de forma transversal como all-rounder, contribuindo na organização, estruturação e validação do contexto da solução. O papel envolveu conectar a visão técnica com a estratégica, apoiando decisões, alinhamento da proposta e garantindo que o projeto fosse consistente, claro e bem direcionado ao problema e impacto proposto.
I am a Computer Science senior currently working as a QA professional in the Artificial Intelligence team at Vivo. I have experience with model evaluation, LLMs, RAG systems, and prompt engineering, and I conduct research in neural networks focused on uncertainty and evaluation metrics. I am passionate about applying generative AI to real-world problems, combining analytical thinking, quality assurance, and engineering to build robust and reliable intelligent systems.
I am particularly interested in generative AI, LLM applications, RAG systems, and multi-agent architectures. I’m looking to deepen my knowledge in AI evaluation, model reliability, and scalable AI systems in production. I’m also interested in collaborating on real-world AI products that combine research, engineering, and quality to build robust and trustworthy intelligent solutions.
I am currently conducting research in neural networks, focusing on uncertainty estimation and model evaluation. My work explores techniques such as Monte Carlo Dropout to improve reliability and robustness in AI systems.
