Optimizing LLM Learning Shots for Story Point Estimation with Search-Based Methods


Core Concepts
Optimizing LLM learning shots improves story point estimation accuracy.
Abstract
Large Language Models (LLMs) benefit from few-shot learning by providing examples before predictions. This study explores using Search-Based methods to optimize the number and combination of examples for improved estimation performance. The CoGEE method is employed to enhance LLM accuracy in estimating story points for agile tasks. Preliminary results show a 59.34% improvement in estimation performance over three datasets compared to zero-shot settings. Computational search involves genetic evolutionary algorithms, and the GPT-4 API is utilized for estimation modeling. The study uses projects from the TAWOS dataset and demonstrates promising results in optimizing LLM learning shots for software effort estimation.
Stats
Our SBSE technique improves the estimation performance of the LLM by 59.34% on average. Confidence intervals are calculated so that this percentage is 95%. We ran the optimization with a population of 50 individuals for 20 generations. For an n sized sample, dof = n − k, where k is the number of parameters to be estimated (here k = 1). We use NSGA-II, a popular multi-objective evolutionary algorithm for optimization.

Deeper Inquiries

How can optimizing learning shots impact other machine learning tasks beyond story point estimation

Optimizing learning shots can have a significant impact on various machine learning tasks beyond story point estimation. By fine-tuning the examples provided to Large Language Models (LLMs) in few-shot learning scenarios, we can enhance their performance across different domains. For instance, in natural language processing tasks like sentiment analysis or text generation, optimizing learning shots can help LLMs better understand and generate contextually relevant responses with minimal training data. This approach could also be applied to image recognition tasks where providing tailored examples for few-shot learning could improve object detection accuracy and classification capabilities.

What potential drawbacks or limitations might arise from relying heavily on few-shot learning methods

While few-shot learning methods offer advantages such as rapid adaptation to new tasks and efficient use of limited training data, there are potential drawbacks and limitations to consider. One limitation is the risk of overfitting when optimizing learning shots for specific examples, which may lead to reduced generalization on unseen data. Additionally, heavily relying on few-shot learning approaches might result in models that are sensitive to the quality and diversity of the provided examples, potentially leading to biased or inaccurate predictions if not carefully curated. Moreover, the computational cost of repeatedly fine-tuning models with different sets of examples could be prohibitive for large-scale applications.

How can advancements in Large Language Models revolutionize traditional software engineering practices

Advancements in Large Language Models (LLMs) have the potential to revolutionize traditional software engineering practices by offering enhanced capabilities in various areas. LLMs can automate repetitive coding tasks through code generation based on natural language descriptions or comments, streamlining software development processes and reducing manual effort. They can also assist in bug detection and resolution by analyzing code semantics at a deeper level than conventional static analyzers. Furthermore, LLMs enable more accurate documentation generation by summarizing complex technical concepts into understandable language automatically. Additionally, LLMs empower developers with intelligent code completion suggestions based on contextual understanding from vast amounts of programming knowledge available online. This feature enhances productivity and reduces errors during coding sessions. Overall, integrating LLMs into software engineering workflows has the potential to boost efficiency, accuracy, and innovation within development teams while paving the way for more advanced AI-driven tools tailored specifically for software development needs.
