I'm a postdoc in Decentralized Machine Learning. Before, I did my PhD in Computer Science with a Machine Learning specialization and I had the previledge to work under the supervision of Prof. Montresor.
I'm generally interested in Machine Learning, Natural Language Processing, and Social Network Analysis. My PhD research was mainly on Graph Embedding (aka - Network Representation Learning - NRL) and Information Diffusion Analysis. More concretely, i have explored how we can use data from information diffusion events and node attributes in order to learn high-quality embedding of nodes. This is particularly useful in cases where the network under consideration is noisy. For example when it has missing information, such as social links between nodes.
