📝 摘要（中文）
个性识别传统上受限于理论依赖的模型，往往需要适应预定义的心理分类，限制了模型的泛化能力。本文提出了JAM（Judge for Adaptive Metric-Alignment）框架，旨在从发现统一的潜在伪特征出发，捕捉共享的心理结构，而非依赖于特定的个性理论。JAM通过注意力聚合图原型网络学习结构化表示，并结合跨理论协调方法，整合异构数据集。为了提高模型的鲁棒性，采用了LLM作为评判机制，识别模糊样本以指导自适应度量学习。实验结果表明，JAM在跨框架泛化和性能上均有显著提升，推动了理论无关的个性推断。
🔬 方法详解
问题定义：本文旨在解决个性识别中对预定义心理分类的依赖问题，现有方法往往无法有效捕捉潜在的心理特征，导致泛化能力不足。
核心思路：JAM框架的核心思想是通过发现统一的潜在伪特征，学习通用的心理表征，而非依赖于特定的理论标签，从而实现更好的个性推断。
技术框架：JAM框架包括注意力聚合图原型网络和跨理论协调方法，前者用于在嵌入空间中学习结构化表示，后者则整合异构数据集，避免使用预定义标签。
关键创新：JAM的主要创新在于其理论无关的设计，通过自适应度量学习和LLM作为评判机制，显著提高了模型的鲁棒性和数据质量。
关键设计：在技术细节上，JAM采用了聚类方法进行嵌入空间的学习，并通过人类引导的链接和机器引导的一致性来实现数据集的统一，确保了模型在不同数据集上的适应性。

📄 摘要（原文）
Personality recognition has traditionally been constrained by theory-dependent formulations, where models are trained to fit predefined psychological taxonomies rather than uncovering shared underlying behavioral structure. This limits generalization, as personality itself is better understood as theory-invariant, while existing annotations reflect only partial and sometimes inconsistent views of the same latent traits. In this work, we introduce JAM ((J)udge for (A)daptive (M)etric-Alignment), a theory-agnostic framework that shifts learning from adapting to predefined personality theories toward discovering unified latent pseudo-facets that capture shared psychological structure. Rather than constraining the model to any personality taxonomy during training or inference, the framework learns generalizable psychological representations and can infer an individual's latent psychological profile directly from the textual samples, without requiring theory-specific labels. JAM achieves this through an Attention-Pooled Graph Prototypical Network that learns structured representations via clustering in embedding space, together with a Cross-Theory Harmonization (CTH) approach that integrates (i) Human-Guided Linkage and (ii) Machine-Induced Consensus to unify heterogeneous datasets without relying on predefined labels. To further improve robustness and data quality, we incorporate an LLM-as-a-Judge mechanism operating in two configurations, (i) LLM-before-the-loop and (ii) LLM-in-the-loop which identifies ambiguous samples to guide adaptive metric learning. Experiments show that JAM improves cross-framework generalization and performance, establishing a strong step toward theory-agnostic personality inference and supporting low-resource personality theories.
