[Paper] Optimizing Prompts for Text-to-Image Generation

• Language models serve as a prompt interface that optimizes user input into model-preferred prompts.

• Learn a language model for automatic prompt optimization via reinforcement learning.

[Paper] Structured Prompting: Scaling In-Context Learning to 1,000 Examples

• Example use cases:

1. Prepend (many) retrieved (long) documents as context in GPT.

2. Scale in-context learning to many demonstration examples.

[Paper] Extensible Prompts for Language Models

• Extensible interface allowing prompting LLMs beyond natural language for fine-grain specifications

• Context-guided imaginary word learning for general usability

[Paper] Inference with Reference: Lossless Acceleration of Large Language Models

• Outputs of LLMs often have significant overlaps with some references (e.g., retrieved documents).

• LLMA losslessly accelerate the inference of LLMs by copying and verifying text spans from references into the LLM inputs.

• Applicable to important LLM scenarios such as retrieval-augmented generation and multi-turn conversations.

• Achieves 2~3 times speed-up without additional models.

[Paper] Why Can GPT Learn In-Context? Language Models Secretly Perform Finetuning as Meta Optimizers

• According to the demonstration examples, GPT produces meta gradients for In-Context Learning (ICL) through forward computation. ICL works by applying these meta gradients to the model through attention.

• The meta optimization process of ICL shares a dual view with finetuning that explicitly updates the model parameters with back-propagated gradients.

• We can translate optimization algorithms (such as SGD with Momentum) to their corresponding Transformer architectures.
