van de Ruit, M. (author), Billeter, M.J. (author), Eisemann, E. (author)t-distributed Stochastic Neighbour Embedding (t-SNE) has become a standard for exploratory data analysis, as it is capable of revealing clusters even in complex data while requiring minimal user input. While its run-time complexity limited it to small datasets in the past, recent efforts improved upon the expensive similarity computations and...journal article 2021

Pezzotti, N. (author), Thijssen, J.G.L. (author), Mordvinstev, Alexander (author), Höllt, T. (author), Van Lew, B. (author), Lelieveldt, B.P.F. (author), Eisemann, E. (author), Vilanova Bartroli, A. (author)In recent years the t-distributed Stochastic Neighbor Embedding (t-SNE) algorithm has become one of the most used and insightful techniques for exploratory data analysis of high-dimensional data. It reveals clusters of high-dimensional data points at different scales while only requiring minimal tuning of its parameters. However, the...journal article 2020

Condia, Josie E.Rodriguez (author), Augusto da Silva, F. (author), Hamdioui, S. (author), Sauer, C. (author), Reorda, M. Sonza (author)Nowadays, General Purpose Graphics Processing Units (GPGPUs) devices are considered as promising solutions for high-performance safety-critical applications, such as those in the automotive field. However, their adoption requires solutions to effectively detect faults arising in the device during the operative life. Hence, effective in-field...conference paper 2019

Bhosale, P.S. (author), Staring, M. (author), Al-Ars, Z. (author), Berendsen, Floris F. (author)Currently, non-rigid image registration algorithms are too computationally intensive to use in time-critical applications. Existing implementations that focus on speed typically address this by either parallelization on GPU-hardware, or by introducing methodically novel techniques into CPU-oriented algorithms. Stochastic gradient descent (SGD...conference paper 2018

Theodoropoulos, D.N. (author)In this dissertation, we propose a new approach for rapid development of multi-core immersive-audio systems. We study two popular immersive-audio techniques, namely the Beamforming and the Wave Field Synthesis (WFS). Beamforming utilizes microphone arrays to extract acoustic sources recorded in a noisy environment. WFS employs large loudspeaker...doctoral thesis 2011
