Key Points

  • The research aims to identify the limitations of integrated evaluation metrics in machine learning and their impact on model representation.
  • Analyzed integrated evaluation metrics in machine learning contexts.
  • Isolated conditions causing metric aggregation to obscure distinct model representations.
  • Provided a diagnostic assessment of the inferential limits of metric integration.
  • Identified scenarios where metric aggregation leads to identical scores for diverse models.
  • Demonstrated loss of discriminative information despite similar performance metrics.

Abstract

This technical note analyzes the limitations of integrated evaluation metrics commonly used in machine learning. By isolating a minimal condition under which metric aggregation collapses distinct internal model representations into identical scores, it shows how discriminative information may be lost despite apparent performance agreement. The analysis is purely diagnostic and model-agnostic, focusing on the inferential limits imposed by metric integration rather than on specific architectures, training procedures, or optimization strategies.
