1. 1. Moving Target Classification with Radar Point-Clouds and Supervised Contrastive Learning

   University essay from Lunds universitet/Matematisk statistik

   Author : Nils Zandler Andersson; [2021]
   Keywords : Statistical Learning; Machine Learning; Deep Learning; Radar; Radar Point-Clouds; Supervised Contrastive Learning; Mathematics and Statistics;

   Abstract : This thesis deals with radar data for the purpose of moving target classification in the context of surveillance. The radar data in question comes in the form of point-clouds represented as frame-wise histograms with several channels and we seek to improve upon an existing cross-entropy based deep learning classifier using supervised contrastive loss.

3. 2. Boundedness of a Class of Hilbert Operators on Modulation Spaces

   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Nils Zandler Andersson; [2019]
   Keywords : ;

   Abstract : In this work we take interest in frames and modulation spaces. On the basis of their properties, we show how frame expansions can be used to prove the boundedness of a particular class of Hilbert operators on modulation spaces taking advantage of the special category of piece-wise polynomial functions known as B-splines. ..
