About me

Hi there! I’m Daniele Malitesta, a postdoc researcher at CentraleSupélec, Inria (Université Paris-Saclay) working with Prof. Fragkiskos Malliaros.

Previously, I pursued my PhD in Electrical and Information Engineering at Politecnico di Bari under the supervision of Prof. Tommaso Di Noia.

My main research topics are Graph Representation Learning, Recommender Systems, and Multimodal Deep Learning.

Upcoming events

[Jan 16, 2025] I’ll give a talk entitled “Graph-based Imputation to Address Missing Modalities in Multimodal Recommendation” at the HCAI research group in Linz!
[Nov 29, 2024] Me, along with colleagues from CentraleSupélec, Ecole Polytechnique, CNRS, Télécom, and Entalpic will host the LoG 2024 Meetup in Paris. Check our event website.
[Oct 22, 2024] I will present our short paper “Do We Really Need to Drop Items with Missing Modalities in Multimodal Recommendation?” at CIKM 2024 in Boise, Idaho.
[Oct 22, 2024] I will chair the full paper session on graph-based recommendation at CIKM 2024.

[Nov 29, 2024] I’ve been nominated among the outstanding reviewers at LoG 2024!
[Oct 15, 2024] For the second time in a row, I was nominated among the outstanding reviewers at RecSys 2024!
[Oct 06, 2024] The proceedings of the IRonGraphs workshop (co-located with ECIR 2024) are finally out: check them at this link!
[Jul 26, 2024] Our paper “A Novel Evaluation Perspective on GNNs-based Recommender Systems through the Topology of the User-Item Graph” w/ colleagues from Politecnico di Bari has been accepted at RecSys 2024!
