I'm Umanga Bista , originally from Kathmandu and currently a PhD candidate at the Computational media lab, Australian National University .

My PhD supevisors are Prof. Lexing Xie , Dr. Aditya Menon , Dr Alexander Mathews and Dr. Lizhen Qu.

I am interested in applying Machine Learning to multimodal datasets, and submodular optimisation in machine learning. I also like to work with data setreaming systems and fascinated by functional programming.

Current Research + Roles

PhD: Currently, I am working on Picturing everyday knowledge project. My proposed topic for phd is "Comparative Summarisation of Rich Media Collections".

I am a Casual Research engineer in Computational Media labs, where i develop and maintain continuous and scalable data collection and preprocessing pipelines.

Tutor: I am a tutor to Document Analysis course. I tutored in second semester of 2017 and 2018.

Research Interests

  • Machine learning from Multimodal Datasets such as texts, images, graphs
  • submodular optimisation in machine learning
  • Scalable machine learning
