🧵Our paper “Gegenbauer Graph Neural Networks for Time-Varying Signal Reconstruction” was accepted in IEEE Transactions on Neural Networks and Learning Systems (some weeks ago)! 📄 Read it here: doi.org/10.1109/TNNLS.… 📑 ArXiv link: arxiv.org/abs/2403.19800

Predicting causal effects tends to require a high label ratio, which translates to more interventions and hence higher risk/cost. Our paper “Uplift Modelling under Limited Supervision“, accepted ECML PKDD’24, indicates that smaller experiments could suffice in e-commerce.1/2

Very happy to have collaborated on this paper (now accepted at ECML PKDD'24) about uplift modelling in the e-commerce scenario leveraging #GNNs 🚀 Amazing work led by George Panagopoulos and supervised by Fragkiskos Malliaros and Jun Pang 😎

(Big) life update 😊: With Victor Schmidt 💀🐔 & Mathieu Galtier, we are co-founding @Entalpic_ai, an AI startup for chemistry and materials discovery. Our mission is to develop science and its applications for a fair and ecological transition. In stealth but hiring entalpic.notion.site/Entalpic-is-hi…

"Do we really need to drop items with missing modalities in #multimodal #recsys?" Not at all! Our short paper at #CIKM2024 ACM CIKM 2024 proposes untrained #graph propagation to impute missing modalities as a **preprocessing** stage 🚀 w/ Emanuele Rossi Claudio Pomo Fragkiskos Malliaros Tommaso Di Noia

Recently, #diffusion models in CV have been shown to produce possibly #biased images, eventually leading to #unfairness. Thus, a natural question arises: "Does this also occur in #recommendation?" Maybe yes 🫢 Take a look at our pre-print 👇👇 arxiv.org/abs/2409.04339
