提出情感启动评分,自动识别生理数据中的情绪干扰点

Affective Priming Score: A Data-Driven Method to Detect Priming in Sequential Datasets

  • 基于数据驱动方法为每个数据点打分,量化情绪启动影响程度
  • 在SEED和SEED-VII数据集上,去启动数据使误分类率显著下降
  • 适合关注情绪计算数据质量与模型鲁棒性的研究者

情感启动是情感计算中模糊性挑战的典型体现。尽管社区多从标签角度解决该问题,但对生理信号等数据本身受启动效应影响的研究仍不足。受启动影响的数据会导致学习模型误判。本文提出情感启动评分(APS),一种数据驱动方法,为序列中每个数据点赋值,量化其受启动影响的程度。在包含充分情绪转换的SEED和SEED-VII数据集上验证该方法。使用相同模型配置,在原始数据与去启动序列上分别训练,发现去启动序列的误分类率显著降低。本工作从数据层面识别并缓解启动效应,提升模型鲁棒性,并为情感计算数据集的设计与采集提供重要启示。

原文摘要 · Abstract (English)

Affective priming exemplifies the challenge of ambiguity in affective computing. While the community has largely addressed this issue from a label-based perspective, identifying data points in the sequence affected by the priming effect, the impact of priming on data itself, particularly in physiological signals, remains underexplored. Data affected by priming can lead to misclassifications when used in learning models. This study proposes the Affective Priming Score (APS), a data-driven method to detect data points influenced by the priming effect. The APS assigns a score to each data point, quantifying the extent to which it is affected by priming. To validate this method, we apply it to the SEED and SEED-VII datasets, which contain sufficient transitions between emotional events to exhibit priming effects. We train models with the same configuration using both the original data and priming-free sequences. The misclassification rate is significantly reduced when using priming-free sequences compared to the original data. This work contributes to the broader challenge of ambiguity by identifying and mitigating priming effects at the data level, enhancing model robustness, and offering valuable insights for the design and collection of affective computing datasets.
