A Classifier That Teaches Itself: Self-Improving, Frozen-gate Training (SIFT) for Dynamic Document Classification

SIFT is a dynamic document classification service that uses a low-cost CPU pipeline and escalates only uncertain cases to an LLM judge.

SIFT (Self-Improving, Frozen-gate Training) addresses enterprise classification bottlenecks by combining a SPLADE sparse encoder with a LightGBM head. It routes low-confidence predictions to an LLM judge, which then updates the classifier, enabling continuous improvement without manual labeling projects.
