Using Text-Based Life Trajectories from Swedish Register Data to Predict Residential Mobility with Pretrained Transformers
Philipp Stark, Alexandros Sopasakis, Ola Hall +1
We transform large-scale Swedish register data into textual life trajectories to address two long-standing challenges in data analysis: high cardinality of categorical variables an…
Early-Scheduled Handover Preparation in 5G NR Millimeter-Wave Systems
Dino PjaniÄ, Alexandros Sopasakis, Andres Reial +1
The handover (HO) procedure is one of the most critical functions in a cellular network driven by measurements of the user channel of the serving and neighboring cells. The success…
Improved Anomaly Detection through Conditional Latent Space VAE Ensembles
Oskar à ström, Alexandros Sopasakis
We propose a novel Conditional Latent space Variational Autoencoder (CL-VAE) to perform improved pre-processing for anomaly detection on data with known inlier classes and unknown…
Enhancing Carbon Emission Reduction Strategies using OCO and ICOS data
Oskar à ström, Carina Geldhauser, Markus Grillitsch +2
We propose a methodology to enhance local CO2 monitoring by integrating satellite data from the Orbiting Carbon Observatories (OCO-2 and OCO-3) with ground level observations from…
