Increasingly, sensor-rich smart systems are being created to monitor and control cyber-physical environments. The models are being constructed and tested based on historical sensor data. However, due to environmental changes, over time the quality of environmental representation and the quality of trained computational models decreases. This phenomenon is well-known as concept drift, a change in statistical properties of continuously generated data over time, e.g., sensor streams, which results in degradation of the performance of models that were developed before the change occurred and reduction in the quality of reasoning on new data, since patterns that were mined previously are now obsolete.

In this project, the PhD student will create a formal framework for environmental representation from raw sensor streams in the presence of environmental change with the ability to describe concept drift over time, for example, with explainable logical formulas, or behavioral rules. The automated adaptive mechanism of environment representation from sensor data will detect changes, adapt the model and explain this adaptation, consider several concurrent interpretations in cases of uncertainty, and understand the limitations of the current models. The framework will be applied to existing real-world use cases.

What are you going to do?

Your tasks and responsibilities:

• perform novel research in the area of concept drift, IoT systems, digital twins, defining formal models, engineering respective software frameworks, scientifically testing and evaluating your approach;
• establish collaborations with other researchers within and outside of UvA;
• publish and present your work in journals and international conferences;
• be an active part of the Informatics Institute, in particular, Intelligent Data Engineering (INDElab) group, and their activities;
• assist in educational activities and supervision of bachelor and master students;
• complete and defend a PhD thesis within the official appointment duration of four years.

Your daily supervisor will be Dr. Victoria Degeler.

What do you have to offer?

• A Master’s degree (or equivalent) in computer science, artificial intelligence or a related subject (or be close to completing the degree);
• demonstrated interest in AI reasoning systems, algorithms, IoT, context-aware pervasive computing, machine learning and data analysis, software engineering;
• good programming skills;
• high motivation in pursuing academic research;
• fluency in English, both written and spoken.

Our offer

A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students. The preferred starting date is flexible.

The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 2,901 in the first year to € 3,707 in the last year (scale P). UvA additionally offers an extensive package of secondary benefits, including 8% holiday allowance and a year-end bonus of 8.3%. The UFO profile ‘PhD candidate’ is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.

Besides the salary and a vibrant and challenging environment at Science Park, we offer you multiple fringe benefits:

• 232 holiday hours per year (based on fulltime) and extra holidays between Christmas and 1 January;
• Multiple courses to follow from our Teaching and Learning Centre;
• A complete educational program for PhD students;
• Multiple courses on topics such as leadership for academic staff;
• Multiple courses on topics such as time management, handling stress and an online learning platform with 100+ different courses;
• 7 weeks birth leave (partner leave) with 100% salary;
• Partly paid parental leave;
• The possibility to set up a workplace at home;
• A pension at ABP for which UvA pays two third part of the contribution;
• The possibility to follow courses to learn Dutch;
• Help with housing for a studio or small apartment when you’re moving from abroad.
