Triple-CFN: Separating Concepts and Features Enhances Machine Abstract Reasoning Ability

Ruizhuo Song, Beiming Yuan

TL;DR

The paper tackles visual abstract reasoning, showing deep models struggle with inductive pattern learning due to conflicts among high-dimensional concepts when represented in low-dimensional spaces. It proposes CFN and its enhanced version Triple-CFN to separate concept extraction from feature extraction and to model their interactions via cross-attention, augmented by a dual EM process and decorrelation (covariance-based) supervision to mitigate overfitting. It further extends the framework with metadata-driven supervision (Meta Triple-CFN) and introduces a Re-space layer to build a stable feature space, achieving state-of-the-art or competitive results on RPM datasets (RAVEN, I-RAVEN, PGM) and Bongard-logo, with improved interpretability. The work demonstrates that separating concepts and features, guided EM optimization, and space construction substantially boost reasoning accuracy and generalization, with practical implications for reasoning in diverse DL domains.

Abstract

This paper introduces innovative frameworks for visual abstract reasoning, aiming to boost deep learning model performance. It emphasizes the importance of separating abstract concept and reasoning feature extraction processes. The effectiveness of the Cross-Feature Network (CFN) and its enhanced version, Triple-CFN, validates this approach. Challenges in visual abstract reasoning arise from complex pattern induction and conflicts in low-dimensional representations. To address these, a dual Expectation-Maximization (EM) process is introduced during CFN training, optimizing module parameters to synthesize non-conflicting concepts. However, the dual EM process may overfit, so mutual and decorrelation supervisions are designed to assist feature extraction, with decorrelation supervision proving effective. Leveraging metadata in Raven's Progressive Matrices (RPM), the paper proposes Meta Triple-CFN, improving reasoning accuracy and interpretability. Additionally, a Re-space layer is designed for feature space construction, further enhancing Triple-CFN's reasoning accuracy. These innovative designs provide effective solutions for abstract reasoning problem solvers, benefiting multiple deep learning domains.
