Question 1: True or false
mediumAI-checkedFine-tuning & PEFTFLAN fine-tunes pretrained language models on over 60 NLP datasets phrased as natural-language instructions (instruction tuning) and evaluates them zero-shot on task clusters held out of training. True or false: in its scaling ablation, instruction tuning improved held-out zero-shot performance at every model size tested, from 422M to 137B parameters.
