A TU/Delft researcher has developed an AI coach to help people quit smoking and vaping. Nele Albers opted for so-called reinforcement learning (RL) when developing the tool. This is a form of machine learning where a model learns through rewards, similar to how humans learn behaviour. Albers based her research on insights from behaviour change theories and data from three large-scale studies with more than 500 participants each. This week, she defended her thesis.
Apart from the technical side, Albers also researched ethical, economic and psychological aspects. Moreover, she analysed how different factors contribute to effective behavioural change. These include issues such as how to convince smokers to quit, what is required of them and who should support them.
