• Abstract summary: Large language models (LLMs) can perform zero-shot classification, but large-scale deployment can be expensive. This paper introduces an LLM chain ensemble methodology that aligns multiple LLMs in a sequence, routing data subsets to subsequent models. Our results show that the chain ensemble method often exceeds the performance of the best individual model in the chain and achieves substantial cost savings.

• Abstract: The ability of large language models (LLMs) to perform zero-shot classification makes them viable solutions for data annotation in rapidly evolving domains where quality labeled data is often scarce and costly to obtain. However, the large-scale deployment of LLMs can be prohibitively expensive. This paper introduces an LLM chain ensemble methodology that aligns multiple LLMs in a sequence, routing data subsets to subsequent models based on classification uncertainty. This approach leverages the strengths of individual LLMs within a broader system, allowing each model to handle data points where it exhibits the highest confidence, while forwarding more complex cases to potentially more robust models. Our results show that the chain ensemble method often exceeds the performance of the best individual model in the chain and achieves substantial cost savings, making LLM chain ensembles a practical and efficient solution for large-scale data annotation challenges.

  Manual annotation of data is labor-intensive, time-consuming, and costly. In-context learning (ICL) in which some examples related to the task are given in the prompt can lead to inefficiencies and suboptimal model performance. This paper presents experiments comparing several LLMs, considering different embedding models, across various datasets for the Named Entity Recognition (NER) task.

  Large Language Models (LLMs) suffer from high computational costs, environmental inefficiency, and potential biases inherited from monolithic architectures. We propose a collaborative framework, GRA, that aggregates specialized roles across small LLMs to generate high-quality, diverse, and reliable data. Our results challenge the necessity of monolithic large models for high-quality data synthesis, advocating instead for strategic coordination of smaller agents.

  We introduce LLM-Lasso, a framework that leverages large language models (LLMs) to guide feature selection in Lasso regression. LLMs generate penalty factors for each feature, which are converted into weights for the Lasso penalty using a simple, tunable model. Features identified as more relevant by the LLM receive lower penalties, increasing their likelihood of being retained in the final model.
