Uncovering structure in high-dimensional and dynamic datasets.
About Me
I am currently a PhD student at Simula Metropolitan Center for Digital Engineering (SimulaMet) studying matrix and tensor factorizations, specifically for temporal data.
My background is on computer science, specializing in data mining and scientific computing. I am especially intrigued by unsupervised machine learning due to its capacity to discover patterns that are not predefined and relationships we did not even know to look for.
