Master Thesis - Decoding Occupancy: Classifying User Activity from Building Power Consumption with Machine Learning

At the Institute of Climate and Energy Systems Engineering (ICE-1) we focus on the development of models and algorithms for simulation and optimization of decentralized, integrated energy systems. Such systems are characterized by high shares of renewable energies and increasing sector coupling, which leads to high spatial and temporal variability of energy supply and demand as well as a high degree of interdependence of material and energy flows. Our research at the ICE institute aims to provide scalable and faster-than-real-time capable methods and tools that enable the energy-optimal, cost-efficient and safe design and operation of future energy system.

Your Job

Design a data pipeline to extract and preprocess activity-relevant features from monitored building power consumption data
Develop a classification algorithm (e.g., based on Gaussian Processes or related probabilistic models) to infer user activity states from power signals
Validate and benchmark your method against alternative classifiers on real building datasets
Quantify and formalize uncertainty estimates to support reliable deployment in real-world building management systems

Your Profile

Excellent university degree (Bachelor) in field of Data Science or a comparable field i.e. Electrical Engineering, Computer Science/Engineering, Physics
Strong mathematical background
Interest in energy systems, power grids and its components
Excellent knowledge and experience in programming Python
Excellent knowledge and experience in machine learning
Experience with git is welcome
Excellent ability for cooperative collaboration
Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the ), ideally supported by a certificate confirming the language level
Prior German knowledge is not strictly required
