Cognitive Thermometers: Machine Learning and Logical Complexity

In this article, we propose that machine learning provides a somewhat more agnostic approach to measuring semantic complexity.

Key points

  • How does the human mind represent semantic categories?
  • Why do natural languages favor certain meanings over others?
  • We review emerging evidence that logic and machine learning often yield converging results on relative complexity and its resulting effects in semantic typology.
  • We argue that treating machine learning models as "cognitive thermometers" enables a unified approach to complexity that bridges symbolic logic and connectionist AI.
