The subtraction construction from TM-001 scores higher than a logistic regression and a linear SVM trained to capture the same concept under the report's cosine-similarity evaluation. The authors caution that the classifiers' lower values likely stem from this evaluation setup and may not persist under another metric.
Evidence
correlational
Key metric
cosine similarity to the empirical shift, mostly burned and winter: mean difference 0.713 and 0.799, logistic regression 0.503 and 0.725, linear SVM 0.361 and 0.604
Caveat
The authors state that the lower classifier scores likely stem from the evaluation metric and identify the lack of alternative evaluation methods as the main limitation of the comparison.
