Riassunto
Among the various challenges that machine learning addresses, this thesis focuses on the problem of graph quantification. Quantification is the task of estimating the class prevalence values (or
class priors) within a sample of unlabelled data points that exhibit Dataset Shift. Graph (or Network) quantification extends this task to the graph setting, which is characterized by data points that are interconnected with each other.
The thesis analyzes the impact of quantification methods and graph learning methods in the context of graph quantification. Moreover, it provides a new state-of-the-art method, GESN-SLD, that outperforms all the previously presented methods in the literature.
