Me talking during the Zoom Thesis Defense

Every December since 2015, I have taken some time to write my annual review, a practice that was originally inspired by James Clear (see my 2019, 2018, 2017, 2016, 2015, and 2014 versions). The review's goal is to reflect on the previous year and identify what went well, what could have gone better, and what I’m working toward. This practice enables me to celebrate the efforts and milestones I have made over the past 12 months while examining the bottlenecks and limitations I could have improved upon. The review is a deeply personal report, letting me see myself for who I am and think about the type of person I want to become. This year’s format is inspired by David Perell, which consists of five parts. …

Last month, I had the opportunity to attend the Toronto Machine Learning Summit 2020, organized by the great people at the Toronto Machine Learning Society. I previously attended their MLOps event in the summer, which I also have written an in-depth recap here.

The summit aims to promote and encourage the adoption of successful machine learning initiatives within Canada and abroad. There was a variety of thought-provoking content tailored towards business leaders, practitioners, and researchers. In this long-form post, I would like to dissect content from the talks that I found most useful from attending the conference.

The post consists of 4…
