FitLaM / ULMFiT: practical language-model fine-tuning for text classification

Contribution grade

Transfer learning for language models · Human-designed research method or resource

Reference score160,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Developed general-domain LM pretraining, target-domain adaptation and classifier fine-tuning using discriminative layerwise rates, slanted triangular schedules, gradual unfreezing and pooled recurrent states.

Scientific scope

Developed general-domain LM pretraining, target-domain adaptation and classifier fine-tuning using discriminative layerwise rates, slanted triangular schedules, gradual unfreezing and pooled recurrent states. Januaryv1 is FitLaM with five datasets; finalACL paper is ULMFiT with six, retained as one contribution rather than two methods. Inherits LM fine-tuning, AWD-LSTM, triangular rates and chain-thaw-style gradual adaptation. Universal names practical reuse criteria, not proof for every NLP task or100fold universal sample efficiency; pretraining and tuning costs remain.
