Yasantha Niroshan

Graduate Research Assistant · University of Moratuwa

I work on machine learning under tight resource budgets.

I hold a B.Sc. (Hons) in Computer Science and Engineering from the University of Moratuwa, where I'm now a Graduate Research Assistant working on predictive monitoring. I was previously Lead Software Engineer at RoboticGen.
