On the Evolution of A.I. and Machine Learning: Towards a Meta-level Measuring and Understanding Impact, Influence, and Leadership at Premier A.I. Conferences

no code implementations26 May 2022 Rafael B. Audibert, Henrique Lemos, Pedro Avelar, Anderson R. Tavares, Luís C. Lamb

This work also contributes, to a certain extent, to shed new light on the history and evolution of AI by exploring the dynamics involved in the field's evolution by looking at papers published at the flagship AI and machine learning conferences since the first International Joint Conference on Artificial Intelligence (IJCAI) held in 1969.

Neural-Symbolic Relational Reasoning on Graph Models: Effective Link Inference and Computation from Knowledge Bases

no code implementations5 May 2020 Henrique Lemos, Pedro Avelar, Marcelo Prates, Luís Lamb, Artur Garcez

The recent developments and growing interest in neural-symbolic models has shown that hybrid approaches can offer richer models for Artificial Intelligence.

Graph Colouring Meets Deep Learning: Effective Graph Neural Network Models for Combinatorial Problems

2 code implementations11 Mar 2019 Henrique Lemos, Marcelo Prates, Pedro Avelar, Luis Lamb

Our results thus contribute to the standing challenge of integrating robust learning and symbolic reasoning in Deep Learning systems.

Typed Graph Networks

2 code implementations23 Jan 2019 Marcelo O. R. Prates, Pedro H. C. Avelar, Henrique Lemos, Marco Gori, Luis Lamb

To illustrate the generality of the original model, we present a Graph Neural Network formalisation, which partitions the vertices of a graph into a number of types.

Multitask Learning on Graph Neural Networks: Learning Multiple Graph Centrality Measures with a Unified Network

no code implementations11 Sep 2018 Pedro H. C. Avelar, Henrique Lemos, Marcelo O. R. Prates, Luis Lamb

We then show that a GNN can be trained to develop a \emph{lingua franca} of vertex embeddings from which all relevant information about any of the trained centrality measures can be decoded.

Learning to Solve NP-Complete Problems - A Graph Neural Network for Decision TSP

3 code implementations8 Sep 2018 Marcelo O. R. Prates, Pedro H. C. Avelar, Henrique Lemos, Luis Lamb, Moshe Vardi

Our model is trained to function as an effective message-passing algorithm in which edges (embedded with their weights) communicate with vertices for a number of iterations after which the model is asked to decide whether a route with cost $<C$ exists.
