Sparse Relational Reasoning with Object-Centric Representations

Bibliographic Details
Title: Sparse Relational Reasoning with Object-Centric Representations
Authors: Spies, Alex F., Russo, Alessandra, Shanahan, Murray
Publication Year: 2022
Subject Terms: Computer Science - Machine Learning, Computer Science - Artificial Intelligence, I.2.10, I.2.6
More Details: We investigate the composability of soft-rules learned by relational neural architectures when operating over object-centric (slot-based) representations, under a variety of sparsity-inducing constraints. We find that increasing sparsity, especially on features, improves the performance of some models and leads to simpler relations. Additionally, we observe that object-centric representations can be detrimental when not all objects are fully captured; a failure mode to which CNNs are less prone. These findings demonstrate the trade-offs between interpretability and performance, even for models designed to tackle relational tasks.
