New research disentangles SSL pipeline tuning from classifier optimization

A new research paper introduces SemiScope, a method designed to disentangle the effects of tuning semi-supervised learning (SSL) pipelines versus tuning the downstream classifier in security classification tasks. The study found that optimizing the classifier alone often recovers a significant portion of the performance gains achieved by fully optimizing the entire SSL pipeline. The paper proposes a simpler approach: using Self-Training with a Bayesian Optimization-tuned classifier and a validation-set tuned decision threshold, which performs comparably to fully supervised methods at higher label percentages.
