Gold definitionUpdated Apr 2, 2026

Definition

IFP(SUM) is a recursive extension of First-Order Logic with Summation (FO(SUM)), designed for querying weighted finite structures. It serves as a specialized query language for machine learning models, particularly neural networks represented as weighted graphs.

At a glance

Executive summary

IFP(SUM) is a specialized logic used to ask complex questions about machine learning models, especially neural networks. It treats these models as weighted graphs and allows researchers to formally analyze their structure and behavior, helping to understand how they work and what they can compute.

TL;DR

IFP(SUM) is a powerful logic for formally querying and analyzing machine learning models, particularly neural networks, by treating them as weighted graphs.

Key points
