Algorithm Distillation treats learning to reinforcement learn as an across-episode sequential prediction problem. A dataset of learning histories is generated by a source RL algorithm, and then a causal transformer is trained by autoregressively predicting actions given their preceding learning histories as context.Sep 3, 2023 · Abstract The goal of meta-learning is to learn to adapt to a new task with only a few labeled examples. Inspired by the recent progress in large language models, we propose in-context tuning (ICT), which recasts task adaptation and prediction as a simple sequence prediction problem: to form the input sequence, we concatenate the task instruction, labeled in-context examples, and the target ...

While it has been widely studied in NLP, it is still a relatively new area of research in computer vision. To reveal the factors influencing the performance of visual in-context learning, this paper shows that prompt selection and prompt fusion are ... experience, and response). The mind naturally seeks meaning in context by searching for relationships that make sense and appear useful. Building upon this understanding, contextual learning theory focuses on the multiple aspects of any learning environment, whether a classroom, a laboratory, a computer lab, or a worksite.In-Context Learning: In-context learning refers to the ability to infer tasks from context. For example, large language models like GPT-3 (Brown et al.,2020) or Gopher (Rae et al.,2021) can be directed at solving tasks such as text completion, code generation, and text summarization by specifying the task through language as a prompt. Large language models (LMs) are able to in-context learn—perform a new task via inference alone by conditioning on a few input-label pairs (demonstrations) and making predictions for new inputs. However, there has been little understanding of how the model learns and which aspects of the demonstrations contribute to end task performance.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 Another type of in-context learning happens via “chain of thought” prompting, which means asking the network to spell out each step of its reasoning—a tactic that makes it do better at logic ...Figure1, in-context learning and explicit finetun-ing share a dual view of gradient descent, where ICL produces meta-gradients through forward com-putation, while finetuning computes gradients by back-propagation. Therefore, it is reasonable to un-derstand in-context learning as implicit finetuning. In order to provide empirical evidence to sup- fully apply in-context learning for DST, build-ing on a text-to-SQL approach. • To extend in-context learning to dialogues, we introduce an efficient representation for the dialogue history and a new objective for dialogue retriever design. •Our system achieves a new state of the art on MultiWOZ in zero/few-shot settings. Abstract. We introduce MetaICL (Meta-training for In-Context Learning), a new meta-training framework for few-shot learning where a pretrained language model is tuned to do in-context learning on a large set of training tasks.

Recently, in-context learning has gained popularity over fine-tuning due to its simplicity and improved out-of-domain generalization, and because extensive evidence shows that fine-tuned models pick up on spurious correlations. Unfortunately, previous comparisons of ...In-context learning is a new learning paradigm where a language model observes a few examples and then straightly outputs the test input's prediction. Previous works have shown that in-context learning is sensitive to the provided examples and randomly sampled examples show significantly unstable performance. In this paper, we propose to find ``supporting examples'' for in-context learning ...In this work, we propose an efficient method for retrieving prompts for in-context learning using annotated data and an LM. Given an input-output pair, we estimate the probability of the output given the input and a candidate training example as the prompt, and label training examples as positive or negative based on this probability.May 23, 2023 · Active Learning Principles for In-Context Learning with Large Language Models.

In-context learning is a recent paradigm in natural language understanding, where a large pre-trained language model (LM) observes a test instance and a few training examples as its input, and directly decodes the output without any update to its parameters.Prompt engineering is enabled by in-context learning, defined as a model's ability to temporarily learn from prompts. The ability for in-context learning is an emergent ability of large language models. A prompt is natural language text describing the task that an AI should perform.

Informally, in-context learning describes a different paradigm of “learning” where the model is fed input normally as if it were a black box, and the input to the model describes a new task with some possible examples while the resulting output of the model reflects that new task as if the model had “learned”.
