论文摘要
促使模型表现出令人印象深刻的几次学习能力。在测试时间与单个模型或多个模型的组成一起重复相互作用，进一步扩展了功能。这些组成是概率模型，可以用具有随机变量的图形模型的语言表示，其值是复杂的数据类型，例如字符串。具有控制流和动态结构的情况需要概率编程的技术，这些技术允许以统一语言实施不同的模型结构和推理策略。从这个角度来看，我们将几种现有技术正式化，包括刮擦板 /思想链，验证者，星星，选择 - 推动和工具使用。我们将结果程序称为语言模型级联。
Prompted models have demonstrated impressive few-shot learning abilities. Repeated interactions at test-time with a single model, or the composition of multiple models together, further expands capabilities. These compositions are probabilistic models, and may be expressed in the language of graphical models with random variables whose values are complex data types such as strings. Cases with control flow and dynamic structure require techniques from probabilistic programming, which allow implementing disparate model structures and inference strategies in a unified language. We formalize several existing techniques from this perspective, including scratchpads / chain of thought, verifiers, STaR, selection-inference, and tool use. We refer to the resulting programs as language model cascades.
