XAI框架TriProbe解析多任务分离性
TRIPROBE: Probing Task Separability Beyond Classification for XAI
想了解如何用TriProbe这个XAI框架，从输入、特征和分类器三个层面，把多任务问题拆解成二进制子任务，找出模型处理瓶颈和任务冲突的地方。
TriProbe提出一种多层级探查框架，用于可解释性诊断任务分离性。它通过输入空间、特征表示和分类器输出三个层面，将多任务问题分解为二进制子任务，并使用最大费舍尔判别率作为分离性度量，识别瓶颈和受影响的任务对。在Roshambo sEMG基准测试上，TriProbe揭示了隐藏的故障点，指导数据收集、验证和架构设计。
TRIPROBE: Probing Task Separability Beyond Classification for XAI
Modern evaluation of learning pipelines often reduces to downstream accuracy, leaving open the question of why tasks succeed or fail. TriProbe addresses this gap with a multi-level probing framework for explainable diagnosis of task separability. Rather than treating models as black boxes, TriProbe traces how separability evolves across inputs, learned features, and final classifiers. It decomposes multi-task problems into binary subtasks and applies three complementary probes: a Foundational Probe on input spaces, a Latent Probe on feature representations, and a Final Probe on classifier outputs. Using Maximum Fisher's Discriminant Ratio as a principled separability metric, TriProbe identifies bottlenecks and affected task pairs. Experiments on the Roshambo sEMG benchmark show how TriProbe reveals hidden breakdowns, guiding data collection, validation, and architecture design.
