Researchers use GitHub to test machine learning models by solving real-world problems with an evaluation framework. Assessing the competence of language models in tackling practical software engineering problems is crucial for their advancement.   

SWE-bench, a cutting-edge assessment system, uses GitHub issues and Python pull requests to evaluate these models' coding and problem-solving abilities.  

The results indicate that even the most sophisticated models can only address uncomplicated problems. It emphasizes the urgent requirement for additional progress in language models to facilitate practical and intelligent solutions in software engineering. 

SWE-bench framework

While previous work has introduced evaluation frameworks for language models, these frameworks frequently require additional flexibility and attention to the complexity of software engineering processes. Current benchmarks for code creation account for the complexity of these issues. With its emphasis on patch generation and complex context reasoning, the SWE-bench framework stands out as a more realistic and comprehensive evaluation for enhancing language models with software engineering capabilities. It is crucial in software engineering with machine learning.

Realistic problems

There is a growing demand for reliable benchmarks to assess the performance of language models (LMs) as they find increasing use in the industry. Updated benchmarks are needed to test LMs with realistic challenges. The intricacy and verifiability of software engineering activities through unit tests make them an appealing challenge. As a practical benchmark for evaluating LMs in a software engineering setting, SWE-bench uses GitHub issues and solutions to encourage real-world application and ongoing updating.

Their study encompasses 2,294 practical software engineering issues sourced from GitHub. Language models modify codebases to address problems spanning several functions, classes, and files. The model inputs include task instructions, issue text, retrieved files, sample patches, and a prompt. Model performance evaluation is conducted in two context settings: sparse retrieval and oracle retrieval. 

Evaluation

The evaluation results demonstrate that even advanced models such as Claude 2 and GPT-4 need help solving practical software engineering problems. These models achieve pass rates as low as 4.8% and 1.7%, even when employing the most effective context retrieval techniques. Their models are subject to context changes and perform poorly with longer contexts. Their models tend to produce concise and poorly structured patch files, underscoring the difficulties in managing intricate code-related duties. 

Real-world situations

The study emphasizes the necessity of thoroughly assessing the performance of Language Models (LMs) in realistic, real-world situations as they progress. The assessment framework, SWE-bench, functions as a rigorous and authentic platform for evaluating the capacities of advanced language models in software engineering. The evaluation findings demonstrate the existing constraints of even the most advanced Language Models (LMs) in addressing intricate software engineering difficulties. Their contributions highlight the imperative of creating LMs that are more pragmatic, intelligent, and self-governing. 

SWE-bench evaluation system

The researchers suggest multiple approaches to enhance the SWE-bench evaluation system. Their research proposes enlarging the benchmark by incorporating various software engineering topics. Language models' performance can be improved by investigating enhanced retrieval strategies and multi-modal learning methodologies.   

Conclusion

Future research should address the limits in comprehending intricate code modifications and enhancing the production of properly formatted patch files. Furthermore, these phases aim to establish a more complete and efficient evaluation framework for language models in practical software engineering situations.
