Hello! My name is Wilson Wongso, a Machine Learning Engineer who has just recently finished a Bachelor of Computer Science degree. My main field of interest is low-resource Natural Language Processing (NLP) and Speech Language Processing (SLP).

I am currently a Machine Learning Engineer at Bookbot. I lead a small team of three and our work focuses on automatic speech recognition, speech synthesis, audio classification, conversational AI, and many more.

I am also an independent researcher at Lazarus NLP. We work on open-source language models for languages of Indonesia. Our main goal is to revive the dying languages of Indonesia through speech and language technology.

We have just recently released a pre-print paper titled NusaBERT: Teaching IndoBERT to be Multilingual and Multicultural. The paper discusses the challenges of Indonesia’s linguistic landscape and how we developed NusaBERT, a multilingual and multicultural language model for Indonesia.

Before this position, I was mainly an esports content writer at Hybrid Indonesia where I discuss competitive gaming, professional players & teams, do interviews, and occasionally mix a little machine learning in my writing. You can view my articles on Notion.

School Curriculum: Indonesian National vs. Cambridge International
As I enter my freshman year in university, I’m gradually exposed to more people and their various backgrounds. The more I chat with my new friends, the more I get to understand one major difference that I’ve overlooked all this time – a school’s curriculum.

The Absurd and Ironic Indonesian Reading Culture
While a lot of people abroad are racing to read hundreds of books per year, the Indonesian people are famous for having one of the world’s lowest reading interests. This peculiarity is not only concerning to many but also represents a huge irony for a country whose people are immensely active in day-to-day social media activities.

How MOBA Games Killed My Fear of Math
Like many young kids growing up, I hated mathematics. The subject to me seemed blurry, scary, full of large quantities, and looked like I could never catch up to my peers who were excelling in elementary school. More often than not, I will also hear a couple of my schoolmates who argued that this subject is utterly useless in the real world, their most favorite catchphrase being: “why do we even study this?”

M2 World Championship Playoffs Analyses: A Tale of Twists and Turns
After weeks of preparation, quarantine session, and a great show of team fighting skills, the M2 World Championship has finally come to an end, crowning the latest, world’s best team in Mobile Legends Bang Bang. More importantly, M2 marks the end of an era for multiple recurring themes, ranging from the newly crowned champions to those who retired with a quite bitter aftertaste.

Esports Franchising in Nations with Developing Mobile Esports Scene
Esports is one of the most attractive and popular fields to hop into in recent years. It has proven its worth and the amount of attention it gets even from the mainstream public. To a few, esports is merely forming teams and playing as five, but it gets more serious than that. Esports has formed its very own ecosystem outside of casual gaming, and the two realms seem to be growing in their own separate ways.

One-Tap Potential: Jason “f0rsakeN” Susanto’s Youthful Esports Pursuit
When we think of esports athletes, we tend to think of relatively older players who either have dropped out of school to chase their dreams or be semi-responsible for their academic lives. More often than not, it’s tempting to play games over doing homework, since most of us probably dislike the idea of not having fun.
