Intrinsically motivated graph exploration using network theories of human curiosity

1 code implementation11 Jul 2023 Shubhankar P. Patankar, Mathieu Ouellet, Juan Cervino, Alejandro Ribeiro, Kieran A. Murphy, Dani S. Bassett

The theories view curiosity as an intrinsic motivation to optimize for topological features of subgraphs induced by nodes visited in the environment.

Multi-task Bias-Variance Trade-off Through Functional Constraints

no code implementations27 Oct 2022 Juan Cervino, Juan Andres Bazerque, Miguel Calvo-Fullana, Alejandro Ribeiro

In this paper we draw intuition from the two extreme learning scenarios -- a single function for all tasks, and a task-specific function that ignores the other tasks dependencies -- to propose a bias-variance trade-off.

Training Graph Neural Networks on Growing Stochastic Graphs

no code implementations27 Oct 2022 Juan Cervino, Luana Ruiz, Alejandro Ribeiro

In this paper, we propose to learn GNNs on very large graphs by leveraging the limit object of a sequence of growing graphs, the graphon.

Learning Globally Smooth Functions on Manifolds

no code implementations1 Oct 2022 Juan Cervino, Luiz F. O. Chamon, Benjamin D. Haeffele, Rene Vidal, Alejandro Ribeiro

To do so, it shows that under typical conditions the problem of learning a Lipschitz continuous function on a manifold is equivalent to a dynamically weighted manifold regularization problem.

Federated Representation Learning via Maximal Coding Rate Reduction

no code implementations1 Oct 2022 Juan Cervino, Navid Naderializadeh, Alejandro Ribeiro

We propose a federated methodology to learn low-dimensional representations from a dataset that is distributed among several clients.

Training Stable Graph Neural Networks Through Constrained Learning

no code implementations7 Oct 2021 Juan Cervino, Luana Ruiz, Alejandro Ribeiro

Graph Neural Networks (GNN) rely on graph convolutions to learn features from network data.

An Agnostic Approach to Federated Learning with Class Imbalance

no code implementations ICLR 2022 Zebang Shen, Juan Cervino, Hamed Hassani, Alejandro Ribeiro

Federated Learning (FL) has emerged as the tool of choice for training deep models over heterogeneous and decentralized datasets.

Learning by Transference: Training Graph Neural Networks on Growing Graphs

no code implementations7 Jun 2021 Juan Cervino, Luana Ruiz, Alejandro Ribeiro

Graph neural networks (GNNs) use graph convolutions to exploit network invariances and learn meaningful feature representations from network data.

Multi-task Supervised Learning via Cross-learning

no code implementations24 Oct 2020 Juan Cervino, Juan Andres Bazerque, Miguel Calvo-Fullana, Alejandro Ribeiro

In this paper we consider a problem known as multi-task learning, consisting of fitting a set of classifier or regression functions intended for solving different tasks.
