Improving Content Recommendation: Knowledge Graph-Based Semantic Contrastive Learning for Diversity and Cold-Start Users

no code implementations27 Mar 2024 Yejin Kim, Scott Rome, Kevin Foley, Mayur Nankani, Rimon Melamed, Javier Morales, Abhay Yadav, Maria Peifer, Sardar Hamidian, H. Howie Huang

It is essential to provide recommendations that are both personalized and diverse, rather than solely relying on achieving high rank-based performance, such as Click-through Rate, Recall, etc.

Contrastive Learning Descriptive +4

Federated Classification using Parsimonious Functions in Reproducing Kernel Hilbert Spaces

no code implementations8 Sep 2020 Maria Peifer, Alejandro Ribeiro

Instead, each agent must form a local model and decide what information is fundamental to the learning problem, which will be sent to a central unit.

Sparse multiresolution representations with adaptive kernels

no code implementations7 May 2019 Maria Peifer, Luiz. F. O. Chamon, Santiago Paternain, Alejandro Ribeiro

To address the complexity issues, we then write the function estimation problem as a sparse functional program that explicitly minimizes the support of the representation leading to low complexity solutions.
