Hguimaraes random tech notes


Hey there!

tl;dr: I mostly teach computers how to learn and adapt to solve problems.

My names is Heitor Guimarães (@Hguimaraes) and I’m a Data Scientist at Itaú in a partnership program (graduate program) with the Aeronautics Institute of Technology (ITA). My undergraduate degree was in Computer and Information Engineering at the Federal University of Rio de Janeiro (UFRJ), in Brazil.

I’ve been working in the tech industry since 2013, back when I started in the image processing field. Currently I’m focusing on Data Science and Machine Learning, interested on Speech, Sound, NLP and creative AI applications to arts and music. I’m also a MOOC enthusiast and always looking to learn something new through online courses and spread this idea.
