DeepStochLog: Neural Stochastic Logic Programming

1 code implementation23 Jun 2021 Thomas Winters, Giuseppe Marra, Robin Manhaeve, Luc De Raedt

Like graphical models, these probabilistic logic programs define a probability distribution over possible worlds, for which inference is computationally hard.

Learning Representations for Sub-Symbolic Reasoning

no code implementations1 Jun 2021 Giuseppe Marra, Michelangelo Diligenti, Francesco Giannini

Unlike flat architectures like Knowledge Graph Embedders, which can only represent relations between entities, R2Ns define an additional computational structure, accounting for higher-level relations among the ground atoms.

Online Learning of Non-Markovian Reward Models

no code implementations26 Sep 2020 Gavin Rens, Jean-François Raskin, Raphaël Reynouad, Giuseppe Marra

In our formal setting, we consider a Markov decision process (MDP) that models the dynamics of the environment in which the agent evolves and a Mealy machine synchronized with this MDP to formalize the non-Markovian reward function.

A Lagrangian Approach to Information Propagation in Graph Neural Networks

1 code implementation18 Feb 2020 Matteo Tiezzi, Giuseppe Marra, Stefano Melacci, Marco Maggini, Marco Gori

GNNs exploit a set of state variables, each assigned to a graph node, and a diffusion mechanism of the states among neighbor nodes, to implement an iterative procedure to compute the fixed point of the (learnable) state transition function.

Learning in Text Streams: Discovery and Disambiguation of Entity and Relation Instances

no code implementations6 Sep 2019 Marco Maggini, Giuseppe Marra, Stefano Melacci, Andrea Zugarini

We consider a scenario where an artificial agent is reading a stream of text composed of a set of narrations, and it is informed about the identity of some of the individuals that are mentioned in the text portion that is currently being read.
