Parex Resources Innovation Fellowships

We believe our researchers and students can change the world – one discovery and innovation at a time.

The Parex Resources Innovation Fellowships were launched in October 2019 for researchers from across the university who are immersed in academic research and community partnerships leading to start-ups or technology advancement based on new discoveries, insights, and innovation. -- Read more --


Hip, Hack, Array! Hackathon 2021

Two of my PURE Summer 2021 students were part of the winning team of the Hip, Hack, Array! Hackathon 2021. Their team Void-21 addressed how to help students with working from home has amplified this lack of University resources and public accessibilities. Our solution was ResearchGram, based on our own experiences as student researchers struggling to gather research papers at our fingertips. This web application allowed us to use Semantic Analysis to narrow our results with the Top 3 relevant documents from the dataset of the University of Colombia.

KEYNOTE AT IWSIB 2021 - 4th International Workshop on Software-intensive Business, June 14th - ONLINE
The Return-of-Investment Perspective on Machine Learning in Software-Intensive Business

Machine Learning (ML) is widely used for different purposes of Software Engineering. ML has the potential to improve efficiency and effectiveness. However, ML is not a silver bullet but needs proper problem and solution approach adjustment. To make proper decisions on that (how much is enough?), we apply the perspective of Return-on-Investment (ROI). We model ROI analysis of ML in general and instantiate the process in the context of software requirements dependency extraction. For OSS data sets, we analyze decision-making on requirements dependency extraction when (i) exclusively based on accuracy with (ii) doing ROI analysis. As a result, we propose recommendations for the context and degree of usage of ML.
