Vocational choice tests, in their current state, often fall short in delivering personalized and engaging recommendations, resulting in a lack of support during crucial choice moments at school. As a result, students rely heavily on parental advice, potentially limiting later career satisfaction. This research project aims to harness advanced machine learning techniques, such as (deep) reinforcement learning (RL), to offer tailored and improved vocational recommendations considering the individual student's interests.
Recommender systems can be used to match specific vocations or career options to the user, based on the user profile and the characteristics of the vocational choice options. Leveraging the ability of deep learning (DL), deep reinforcement learning (DRL) can be applied in large action spaces, such as vocational choice tests. On the downside, because they use DL, deep RL algorithms and systems are less explainable than conventional RL systems, thereby potentially creating a black-box system.
The primary objective of this PhD project is to design and develop recommender systems that employ innovative algorithms to deliver personalized vocational guidance. By incorporating sophisticated machine learning, we aspire to create a user-centric approach that considers individual interests and preferences. Resulting matches have to be explainable to the user. Therefore, in this PhD project the black-box of DRL algorithms will be opened, for example through simultaneous explanation and policy learning.
Moreover, we aim to integrate feedback mechanisms that allow users to shape and refine their recommendations further. This innovative approach not only enhances the usability of vocational tests but also empowers individuals to make better career choices.
The main research goals are:
1. Designing and implementing explainable (deep) reinforcement learning algorithms for recommender systems. 2. Evaluating algorithm performance through (1) user opinions on the recommendations, (2) user opinions on the vocational choice test itself, and (3) long term satisfaction and relevance of recommendations (validity).Your profile

The CoDE section consists of teachers and researchers with backgrounds in psychology, educational science, mathematics, or computer science. We teach courses on methodology, data-analysis, and cognitive psychology. Our research focuses on data-based solutions for societal problems related to education, health, and human factors. In our teaching and research we make use of the latest developments in measurement and (large-scale) assessment, such as neurophysiology, process data, extended reality, eye-tracking, psychometrics, and machine learning.
CoDE is part of the Department Learning, Data Analytics and Technology (LDT).About the organisation
The Faculty of Behavioral, Management and Social sciences (BMS) aims to play a key role in understanding, jointly developing and evaluating innovations in society. Technological developments are the engine of innovation. As a technical university that puts people first, we tailor them to human needs and behavior and use social engineering to integrate them into society. We also ensure adequate governance at public and private level, and robust, inclusive and fair organizational structures. We do this by developing, sharing and applying high-quality knowledge in Psychology, Business Administration, Public Administration, Communication Sciences, Philosophy, Educational Sciences and Health Sciences. Our research and education in these disciplines revolves around tackling and solving societal challenges. The research programs of BMS are closely linked to the research of the UT institutes Mesa+ Institute for Nanotechnology, TechMed Center and Digital Society Institute.
As an employer, the Faculty of BMS offers work that matters. We equip you to create new possibilities for yourself and for our society. With us, you will become part of a leading technical university with increasing, positive social impact. We offer an open, inclusive and entrepreneurial atmosphere, in which we encourage you to make healthy choices, for example through our flexible, adaptable benefits.Want to know more? Steinrücke, J.
