Contrastive Order Learning: A General Framework for Ordinal Regression

arXiv:2607. 08109v1 Announce Type: new Abstract: We propose contrastive order learning (ConOrd), a contrastive learning framework for ordinal regression that integrates the strengths of contrastive learning and order learning.

FFR: Forward-Forward Learning for Regression

The Forward-Forward (FF) algorithm offers a computationally efficient and biologically plausible alternative to backpropagation (BP) by training neural networks through purely local, layer-wise optimization. However, FF is inherently designed for classification via contrastive positive-negative sample pairs, and extending it to regression poses fundamental challenges: continuous target space lack natural "opposites" for contrastive learning, and the standard goodness function carries no information about target magnitude or ordering.

Ranking Infrared-Visible Fusion the Way Humans Do: A Learned Pairwise Preference Measure

The paper introduces the Learned Perceptual Image Fusion Measure (LPIFM), a model trained on dense human pairwise comparisons to assess infrared-visible image fusion. LPIFM jointly processes both source images and fused candidates using a shared hierarchical encoder, triadic interaction, and a tie-aware objective, achieving high agreement with human judgments and outperforming 19 conventional metrics. The authors release a large comparison corpus, model weights, and code, demonstrating LPIFM’s rapid adaptability to new fusion-evaluation protocols.

Accounting for Bias Enables Sustainable LLM Evaluation

The paper argues that the current LLM-as-a-judge evaluation method, which compensates for systematic measurement bias by increasing the number of comparisons, is statistically unsound and computationally wasteful. It identifies that treating LLM judges as neutral ignores documented biases such as position bias, verbosity bias, judge severity, and self‑enhancement. The authors propose a unified latent variable framework that jointly models pairwise and ordinal data while explicitly correcting for these confounders, enabling reliable rankings with far fewer comparisons and negligible additional compute.
