Weakly Supervised Semantic Segmentation of Multispectral Satellite Images for Land Cover Mapping

M.Sc. Thesis

Student: Esther Ademola

This thesis evaluates deep learning models for deforestation detection using weakly annotated Sentinel-2 satellite imagery. U-Net and DeepLabV3+ outperform traditional methods but face precision challenges. Results highlight the complexities of multispectral remote sensing and the need for improved annotation quality.

Cross Topology Modeling and Optimization of Electrical Drives Using Machine Learning

M.Sc. Thesis

Student: Marius Benkert

This paper addresses challenges in electrical machine simulation by enhancing deep learning approaches that bypass resource-intensive finite element analysis. Building on previous work (Parekh et al., 2022; 2023), it refines a variational autoencoder architecture that maps diverse motor topologies into a unified latent space, improving both training efficiency and optimization robustness compared to earlier models.

Step Detection

M.Sc. Thesis

Student: Muhammad Sarwar

This thesis explores neural network approaches for step detection using accelerometer and gyroscope data. It compares two methods: CNN models that extract spatial features from time-series data with improved accuracy and speed over traditional LSTM models, and a YOLO-like architecture that predicts step start-end pairs with minimal post-processing. The research evaluates models using both traditional metrics and mean absolute error to assess temporal prediction accuracy.

Transfer Learning in Crop Remote Sensing

M.Sc. Thesis

Student: Ana Muñoz Gutiérrez

This research addresses the challenge of estimating global wheat cultivation before harvest seasons, which is difficult due to limited quality data despite wheat's importance for global food security. The study explores deep learning techniques with a focus on transfer learning methods, using satellite imagery combined with US agricultural statistics to predict winter and spring wheat production.
