Methods 2.1. Visual In-Context Learning In-context learning is a new paradigm that originally emerged from large autoregressive language models pre-in-context learning, where the model learns to do a downstream task simply by conditioning on a prompt consisting of input-output examples. The LM learns from these examples without being explicitly pretrained to learn. Thus, it is unclear what enables in-context learning. In this paper, we study how in-context learningIn-context learning is a unique way for language models to learn and perform tasks by only looking at examples of inputs and outputs without making any changes to their internal workings. It is related to the process in that the language model discovers hidden concepts from the data it was previously trained on. And even when the outputs are ...2.1 GPT- 3 for In-Context Learning The in-context learning scenario of GPT- 3 can be regarded as a conditional text generation problem.
