Classical machine learning and data mining methods rely on the assumption that data distribution stays the same during model training and operation. In reality this is is often not the case. As the world is continuously changing, so evolve data that describe it. My research background is in machine learning methods that can diagnose themselves and adapt to changing data distribution over time.
The main outcome of my PhD thesis research was pointing out a distinction between the point in time that change takes place, and optimal training data history for updating predictive models. I have also made contributions in forming optimisation and evaluation criteria for predictive models with evolving streaming data, (inter)active learning for streaming data and adaptive data preprocessing.
