  • 基于传感可区分性构建新型表示目标,分离场景与干扰因素。
  • 在基准测试中优于重建、度量学习等传统方法的诊断表现。
  • 适合关注传感器感知可靠性与表征合理性的研究者。

智能感知系统中的表征通常以重建保真度或下游预测准确率评估,但这些标准无法判断哪些潜在差异是由传感过程合理支持的。在传感器受限环境下,干扰因素可能改变测量值却不改变场景,而不同场景可能因感知能力不足而难以区分。本文将传感器条件下的表征正确性定义为:保留传感支持的场景差异,同时抑制由干扰引起的变异和传感器无法支持的差异。提出‘场景相关观测商’(Scene-Relevant Observation Quotient),作为去噪后传感可区分性的表示目标,并开发了观测商-张量结构自编码器(OQ-TSAE),具备虚假区分、虚假合并、干扰敏感性及潜在排序一致性等诊断能力。在受控基准测试中,商一致性监督显著提升表征正确性诊断性能,优于重建导向、度量学习与对比学习基线。敏感性、扰动与消融实验验证了商对齐监督、可靠商关系与商几何的重要性。互补的真实雷达实验表明,仅用重建的OQ-TSAE变体仍保持良好下游性能、观测退化下的鲁棒性及低种子间变异性。结果表明,传感器条件下的表征不仅应看预测效用,还应检验其潜在空间是否保留了传感所支持的场景区分。

原文摘要 · Abstract (English)

Learned representations in intelligent sensing systems are often evaluated by reconstruction fidelity or downstream prediction accuracy, but these criteria do not specify which latent distinctions are justified by the sensing process. In sensor-conditioned environments, nuisance factors can change measurements without changing the scene, while distinct scenes may be indistinguishable under limited sensing capability. This paper formulates sensor-conditioned representation correctness as preserving sensing-supported scene distinctions while suppressing nuisance-induced and sensor-unsupported variation. We introduce the scene-relevant observation quotient, a representation target induced by sensing-supported distinguishability after nuisance canonicalization, and develop Observation-Quotient Tucker-Structured Autoencoding (OQ-TSAE), a scene-nuisance factorized framework with diagnostics for false distinction, false merge, nuisance sensitivity, and latent ordering consistency. Experiments on a controlled benchmark show that quotient-consistent supervision improves representation-correctness diagnostics over reconstruction-oriented, metric-learning, and contrastive-learning baselines. Sensitivity, perturbation, and ablation studies show the importance of quotient-aligned supervision, reliable quotient relations, and quotient geometry. Complementary real-radar experiments show that a reconstruction-only OQ-TSAE variant retains competitive downstream utility, robustness under observation degradation, and low seed-to-seed variability. These results suggest that sensor-conditioned representations should be evaluated not only by predictive utility, but also by whether their latent geometry preserves sensing-justified scene distinctions.
