1. Meta-Prompting: Enhancing Language Models with Task-Agnostic Scaffolding
Source: https://arxiv.org/abs/2401.12954
This paper proposes meta-prompting, which enhances the functionality and performance of language models (LMs) by transforming a single LM into a multi-faceted conductor that manages and integrates multiple independent LM queries. Meta-prompting guides the LM to break down complex tasks into smaller, more manageable subtasks, which are then handled by distinct “expert” instances of the same LM, each operating under specific, tailored instructions. The LM itself acts as the conductor, ensuring seamless communication and effective integration of the outputs from these expert models. The zero-shot, task-agnostic nature of meta-prompting simplifies user interaction by obviating the need for detailed, task-specific instructions. The research demonstrates the seamless integration of external tools, such as a Python interpreter, into the meta-prompting framework, thereby broadening its applicability and utility. Through rigorous experimentation with GPT-4, the study establishes the superiority of meta-prompting over conventional scaffolding methods.
2. UniMS-RAG: A Unified Multi-source Retrieval-Augmented Generation for Personalized Dialogue Systems
Source: https://arxiv.org/abs/2401.13256
This paper presents a novel framework for generating personalized responses in dialogue systems by integrating knowledge from multiple sources. The authors propose UniMS-RAG, a system that unifies knowledge source selection, knowledge retrieval, and response generation tasks into a single sequence-to-sequence paradigm. The framework uses acting tokens and evaluation tokens to guide the selection of knowledge sources and assess the relevance of retrieved evidence. It also incorporates a self-refinement mechanism during inference to iteratively improve the generated response based on consistency and relevance scores. Experiments on two personalized datasets demonstrate UniMS-RAG’s effectiveness in knowledge source selection and response generation, outperforming existing methods. The framework’s flexibility allows it to adapt to various retrieval-augmented tasks and provides new insights into the future of personalized dialogue systems.

The paper introduces Corrective Retrieval-Augmented Generation (CRAG), a method to improve text generation by enhancing the use of retrieved documents. CRAG tackles the problem of inaccurate document retrieval by employing a lightweight evaluator to determine the quality of documents. It also uses large-scale web searches to expand the range of information retrieved. Furthermore, CRAG applies a decompose-then-recompose algorithm to remove unnecessary content from the documents. This method is integrated into existing retrieval-augmented generation models, showing its versatility and effectiveness in producing more accurate and relevant text outputs
4. Memory-Inspired Temporal Prompt Interaction for Text-Image Classification
Source: https://arxiv.org/abs/2401.14856
The paper describes a novel multimodal interaction strategy called Memory-Inspired Temporal Prompt Interaction (MITP), developed by researchers at Zhejiang University and Ritsumeikan University. MITP is designed to enhance text-image classification tasks by mimicking human memory mechanisms, specifically working memory and memory activation. The method involves two stages: an acquiring stage, where temporal prompts are used to capture information from each modality, and a consolidation and activation stage, where a memory hub consolidates and activates the prompts to facilitate inter-modality information exchange. MITP leverages direct interactions between prompt vectors on intermediate layers, reducing the need for additional trainable parameters and memory usage. The researchers demonstrate MITP’s effectiveness on several public datasets, achieving competitive results with a small number of trainable parameters and low memory usage. The method outperforms existing prompt-based methods and late fusion strategies, showcasing its potential for efficient and effective multimodal learning.

6. Investigate-Consolidate-Exploit: A Gene ral Strategy for Inter-Task Agent Self-Evolution
Source: https://arxiv.org/abs/2401.13996
The paper introduces the Investigate-Consolidate-Exploit (ICE) strategy, aimed at advancing AI agents’ adaptability and flexibility through inter-task self-evolution. ICE is a three-stage process designed to enable AI agents to self-evolve by transferring knowledge between tasks. The first stage, Investigate, involves identifying valuable experiences from planning and execution trajectories. The second stage, Consolidate, standardizes these experiences into workflows and pipelines for easy re-utilization. The final stage, Exploit, uses these consolidated experiences to improve the efficiency and effectiveness of new tasks. Experiments conducted using the XAgent framework demonstrate that ICE can reduce API calls by up to 80% and lower the demands on model capabilities, making agent deployment more time and cost-efficient. When combined with GPT-3.5, ICE’s performance is comparable to that of GPT-4, indicating its potential to significantly enhance agent task execution

8. Large Language Models are Superpositions of All Characters: Attaining Arbitrary Role-play via Self-Alignment
Source: https://arxiv.org/abs/2401.12474
Researchers introduced DITTO, a novel self-alignment method that enhances the role-play capabilities of Large Language Models (LLMs) through knowledge augmentation and dialogue simulation. DITTO is designed with a unique role-play evaluation framework that emphasizes consistent role identity, accurate role-related knowledge, and cognitive boundaries, offering a reproducible, explainable, and efficient alternative to manual annotations. The study dissects role-play through cross-supervision, revealing insights into the core of role-play capabilities and demonstrating the limitations of strong-to-weak imitation learning and the generalization potential in role-play styles. DITTO enables LLMs to achieve role-play proficiency without relying on proprietary models like GPT-4, outperforming existing open-source models across various sizes, even without distillation data. The paper also explores the dual nature of role-play, separating it into role-specific knowledge and conversational style, with the latter showing a range of generalization that can be easily acquired by smaller models. The authors aim to inspire further research into the fundamental mechanisms of role-play alignment, challenging the status quo in the field.

10. SliceGPT: Compress Large Language Models by Deleting Rows and Columns
Source: https://arxiv.org/abs/2401.15024
The researchers have introduced a novel concept known as computational invariance, which involves applying orthogonal matrix transformations to weight matrices in transformer models without altering their functionality. Utilizing this concept, they have developed a technique called SliceGPT, which edits signal matrices within transformer architectures by projecting them onto their principal components and subsequently removing certain columns or rows from the transformed weight matrices to achieve model compression. Through extensive experiments on models such as OPT, LLAMA-2, and other large language models (LLMs), the team has demonstrated that SliceGPT can effectively reduce model sizes by up to 30% while maintaining or even surpassing the perplexity of existing compression methods. Furthermore, they have shown that on downstream tasks, all tested models can be compressed by up to 30% using SliceGPT while preserving over 90% of the dense model’s performance.
