A Little About Me

My name is Igor Lima Rocha Azevedo. I'm an Electrical Engineer from the University of Brasília, now a Research Scholar at The University of Tokyo

Originally from Brasília, the capital of Brazil, I am fluent in both English and Portuguese, with some proficiency in Spanish, and I am currently learning Japanese as I live in Japan. As a research scholar, I focus on studying foundational models and recommender systems.

Through this blog, I aim to share my knowledge and insights to help others on their learning journey, particularly, on artificial intelligence and its applications.

    Main Reference: https://arxiv.org/abs/2405.08793 Learning in Latent Variable Models Latent variable models are powerful extensions of probabilistic models. They introduce hidden or unobserved variables to explain dependencies in data that cannot be captured solely by observed variables. These latent variables often represent underlying processes or structures that are not directly measurable. Latent Variable Representation Given a… Read more: A Causality Summary Part III

    Main Reference: https://arxiv.org/abs/2405.08793 Probabilistic Graphical Models Probabilistic Graphical Models (PGMs) are powerful tools that represent the joint probability distribution of a set of random variables in terms of their conditional dependencies, which are typically defined by a graph structure. A fundamental task in PGMs is sampling from the joint distribution, and this can be achieved… Read more: A Causality Summary Part II

    Main Reference: https://arxiv.org/abs/2405.08793 Have you ever thought about the word “causal” in the sentence we’ve all heard: “Smoking causes lung cancer”? It sounds pretty simple, right? The way I  see it, at least, is the following: if someone has lung cancer and they smoke, we assume smoking caused it. smoke — causes —> cancer Okay, but… Read more: A Causality Summary Part I

  • Dash: An Intriguing Framework, to Say the Least
    Code: https://github.com/igor17400/sakura-time-series As a data scientist, you’ve probably had some pretty awesome ideas, and at your best, turned them into cool animations using Python libraries in Jupyter notebooks. But when you tried showing them to someone—like your parents—they might have just seen a bunch of colorful graphs in some weird tool called “Jupyter Notebook.” To… Read more: Dash: An Intriguing Framework, to Say the Least

The Pink Ipê tree, or “Ipê Rosa,” is celebrated for its stunning clusters of pink, trumpet-shaped flowers that bloom in late winter to early spring. This tree, native to Brazil, is a striking symbol of renewal, with its vibrant blossoms often appearing before its leaves.
