Correctness isnt Efficiency: Runtime Memory Divergence in LLM-Generated Code

Prateek Rajput, Yewei Song, Abdoul Aziz Bonkoungou +4

Large language models (LLMs) can generate programs that pass unit tests, but passing tests does not guarantee reliable runtime behavior. We find that different correct solutions to…

Is Small Language Model the Silver Bullet to Low-Resource Languages Machine Translation?

Yewei Song, Lujun Li, Cedric Lothritz +6

Low-resource languages (LRLs) lack sufficient linguistic resources and are underrepresented in benchmark datasets, resulting in persistently lower translation quality than high-res…
