Alexandra (Ola) Zytek
Machine learning algorithms are becoming increasingly powerful - but how can we extend their benefits to a diverse set of real-world domains? Models continue to be black-boxes that confuse and concern users, and applying them can be a difficult and complicated process.
My research aims to bridge the gap between algorithms and real-world users through collaborations with end-users and development of software systems and interfaces that make applying ML with seamless support for the nuances of real-world domains easier.
I am a PhD student at MIT, researching at the Data to AI lab under the supervision of Kalyan Veeramachaneni.
