Understanding Domain-Size Generalization in Markov Logic Networks

no code implementations23 Mar 2024 Florian Chen, Felix Weitkämper, Sagar Malhotra

This behavior emerges from a lack of internal consistency within an MLN when used across different domain sizes.

Simple and Effective Transfer Learning for Neuro-Symbolic Integration

no code implementations21 Feb 2024 Alessandro Daniele, Tommaso Campari, Sagar Malhotra, Luciano Serafini

Then, a NeSy model is trained on the same task via transfer learning, where the weights of the perceptual part are injected from the pretrained network.

Lifted Inference beyond First-Order Logic

no code implementations22 Aug 2023 Sagar Malhotra, Davide Bizzaro, Luciano Serafini

We expand a vast array of previous results in discrete mathematics literature on directed acyclic graphs, phylogenetic networks, etc.

Deep Symbolic Learning: Discovering Symbols and Rules from Perceptions

no code implementations24 Aug 2022 Alessandro Daniele, Tommaso Campari, Sagar Malhotra, Luciano Serafini

In this paper, we propose Deep Symbolic Learning (DSL), a NeSy system that learns NeSy-functions, i. e., the composition of a (set of) perception functions which map continuous data to discrete symbols, and a symbolic function over the set of symbols.

On Projectivity in Markov Logic Networks

no code implementations8 Apr 2022 Sagar Malhotra, Luciano Serafini

We show that, in terms of data likelihood maximization, RBM is the best possible projective MLN in the two-variable fragment.

Weighted Model Counting in FO2 with Cardinality Constraints and Counting Quantifiers: A Closed Form Formula

no code implementations12 Oct 2021 Sagar Malhotra, Luciano Serafini

Weighted First-Order Model Counting (WFOMC) computes the weighted sum of the models of a first-order logic theory on a given finite domain.

Weighted Model Counting in the two variable fragment with Cardinality Constraints: A Closed Form Formula

no code implementations25 Sep 2020 Sagar Malhotra, Luciano Serafini

We introduce the concept of lifted interpretations as a tool for formulating polynomials for WFOMC.
