  106. DART: Differentiable Prompt Makes Pre-Trained Language Models Better Few-Shot Learners

    DART (Differentiable pRompT) trains prompt templates end-to-end via backpropagation, treating prompts as learnable continuous vectors rather than fixed text. It makes small pre-trained language models competitive few-shot learners without scaling to GPT-3 sizes — an important stepping stone between hand-crafted prompts and full fine-tuning.

  107. What Language Model Architecture and Pretraining Objective Work Best for Zero-Shot Generalization?

    Wang, Roberts, Scao et al. (BigScience Architecture Group) conduct a large-scale comparison of model architectures (causal decoder, non-causal decoder, encoder-decoder) and pretraining objectives (autoregressive, masked LM) for zero-shot generalization. The key finding: causal decoders + autoregressive LM win at zero-shot; non-causal decoders + masked LM + multitask fine-tuning win overall.

  108. Multitask Prompted Training Enables Zero-Shot Task Generalization

    T0 shows that training a language model on 2000+ diverse human-authored prompts across 170+ NLP tasks dramatically improves zero-shot generalization to unseen tasks. An 11B T0 model outperformed 175B GPT-3 zero-shot — proving prompt diversity during training matters more than raw scale for generalization.

  109. Prompt Programming for Large Language Models: Beyond the Few-Shot Paradigm

    Reynolds and McDonell (2021) argue that prompting large language models is better understood as programming than as few-shot learning — the few examples in a prompt aren't training data but rather code that specifies the desired computation. This reframing opens up principled prompt design strategies that beat naive templating.

  110. SPoT: Better Frozen Model Adaptation through Soft Prompt Transfer

    Vu, Constant, Al-Rfou, Cer, and Lester (Google Research/UMass, 2022) show that initializing soft prompts from a related source task dramatically improves prompt tuning, achieving near fine-tuning performance while keeping the base model frozen. The result reveals that prompt initialization is a critical and underappreciated factor in parameter-efficient adaptation.
