I am Eliezer de Souza da Silva, a postdoctoral researcher specializing in Data Science, Machine Learning, Generative Models, and Causality. Currently, I am working at the Fundação GetĂșlio Vargas (FGV), School of Applied Mathematics in Rio de Janeiro, Brazil. I have experience in software development and industrial projects as a software engineer, research scientist, and data scientist.
I hold a Ph.D. in Computer and Information Science from NTNU, Norway, where I completed my thesis titled âFactorization Models with Relational and Contextual Information.â I also earned an M.Sc. in Electrical and Computer Engineering from UNICAMP, Brazil, with a dissertation on âMetric Space Indexing for Nearest Neighbor Search in Multimedia Context.â My academic journey began with a B.Sc. in Computer Engineering from UFES, Brazil.
My research focuses on developing advanced probabilistic models to help us answer questions across various scientific domains. My expertise lies in using probabilistic reasoning to integrate uncertainty measures into machine learning models, seeking to increase the robustness and trustworthiness of AI systems. I have worked on probabilistic machine learning, Bayesian statistics, causal discovery, and deep learning, with applications in information retrieval, recommender systems, NLP, time series, physical simulations, and others.
Currently, I am studying and developing generative models for amortized inference, focusing on Generative Flow Networks. This work was produced with Prof. Diego Mesquita while being part of the Green AI Lab.
In addition to my research, I am passionate about education and mentoring. I have designed and delivered course materials, graded coursework and master theses, and mentored B.Sc. and M.Sc. students in ML/AI and applied mathematics. I have also been instrumental in organizing and leading educational initiatives such as the Nordic and Tropical Probabilistic AI School, which aims to bring advanced AI education to diverse audiences.
Outside academia, I enjoy playing music and composition, attending cultural events, traveling, running, playing basketball, practicing meditation, and exploring nature. I usually do those things with my son, friends, and sometimes strangers. I grew up in multiple countries and value cultural exchanges. I am fluent in Portuguese, English, and Cape Verdean Creole and have basic to intermediate knowledge of French and Spanish.
