The Global NLP Lab. Jan 8. 1. In-context learning (ICL) is an exciting new paradigm in NLP where large language models (LLMs) make predictions based on contexts augmented with just a few training examples. LLMs are able to extract patterns from the examples provided in the context, and use them to perform many complex NLP tasks.Figure 1.2: Larger models make increasingly efficient use of in-context information. We show in-context learning performance on a simple task requiring the model to remove random symbols from a word, both with and without a natural language task description (see Sec.3.9.2). The steeper “in-context learning curves” for large models demonstrate Argument 1 (Macroscopic co-occurence) : Transformer language models undergo a “phase change” early in training, during which induction heads form and simultaneously in-context learning improves dramatically.

Symbol tuning leverages the intuition that when a model cannot use instructions or natural language labels to figure out a task, it must instead do so by learning the input-label mappings ... We study how in-context learning (ICL) in language models is affected by semantic priors versus input-label mappings. We investigate two setups-ICL with flipped labels and ICL with semantically-unrelated labels-across various model families (GPT-3, InstructGPT, Codex, PaLM, and Flan-PaLM).
