New method uses discrete diffusion models for training-free multi-label text classification

Researchers have introduced dLLM-SetScore, a novel method that leverages discrete masked-diffusion language models for multi-label text classification without requiring task-specific fine-tuning. This approach involves posing yes/no questions for each potential label and comparing the probabilities of the answer tokens. To avoid biases, the method employs per-label scoring, placing each label in the same syntactic position to prevent order-dependent artifacts observed in previous methods. Evaluations on datasets like Reuters and GoEmotions demonstrated that LLaDA-Instruct checkpoints, using this protocol, achieved high training-free performance, outperforming other models including SetFit and supervised classifiers in several comparisons.
