December 2024 monthly summary for aeon-toolkit/aeon. Primary work focused on clarifying the evaluation metrics configuration for LITETimeClassifier and IndividualLITEClassifier. Delivered documentation clarification that specifies accepted metrics parameter types (strings, functions, or Keras Metric instances) and includes a link to Keras docs to guide users on configuring evaluation metrics during training. This work improves usability and reduces misconfiguration during model evaluation. Related commit tracked under [DOC] LITE Time classifier metrics (#2464).
