| Denoising Diffusion Probabilistic Models (DDPMs) are a highly popular class of deep generative models that have been successfully applied to various problems, including image and video generation. Recently, there have been attempts to apply these models to time-series data. However, they are not enough for modeling spatial-temporal interactions. They primarily focus on temporal dependencies within individual sensors, neglecting the spatial correlations between different nodes. In reality, objects are spatially correlated with each other. This project aims to explore a graph-based denoising diffusion probabilistic model to jointly capture both temporal dependencies and spatial interactions. - Artificial Intelligence and Signal and Image Processing, Civil Engineering, Communications Technologies, Electrical and Electronic Engineering, Environmental Engineering, Interdisciplinary Engineering

| This project is part of a collaboration between the IMOS lab and Matterhorn Gotthard Bahn, a railway company operating in the Swiss Alps. The student will work on developing computer vision algorithms for automated visual inspection of retaining walls around railway tracks. Retaining (or supporting) walls are crucial infrastructure elements responsible for maintaining the structural integrity of terrains around railway tracks and ensure safe operation. They are subject to wear and damages including cracks, concrete cancer (i.e., alkali–silica reaction), displacements, erosion and water infiltration. Images of retaining walls have already been collected and labels are available. The goal will be to design algorithms to estimate the condition of a wall, with a focus on robustness, transfer learning, and explainability (XAI). - Engineering and Technology, Information, Computing and Communication Sciences

| Many graphs in real-world applications are text-attributed graphs (TAG). Examples include the description of the condition of sensors and pipes and the water distribution network over the junctions, the posts on a social media platform and the following graph over the users, the text of academic articles and the citation network over these articles, among others. This project focuses on combining the power of graph neural networks (GNNs) and large language models (LLMs) to extract information from both the text modality and the graph modality to facilitate learning on TAGs in engineering applications. - Artificial Intelligence and Signal and Image Processing
