To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…
