NeuroStat evaluation beyond English and current application domains

Investigate the effectiveness of NeuroStat and extend the MOSAIC benchmark to multilingual corpora, particularly low-resource languages, and specialized domains such as code generation and legal documents.

Background

NeuroStat is evaluated primarily on English-language texts from selected domains, including news, creative writing, and biomedical abstracts. The paper identifies the effectiveness of the framework in multilingual settings—especially for low-resource languages—and in specialized domains such as code generation and legal documents as unresolved because these settings have not yet been evaluated.

The proposed future investigation would require expanding both the MOSAIC benchmark and NeuroStat’s evaluation protocol to assess robustness and detection performance across these cross-lingual and cross-domain conditions. The issue is explicitly presented as a limitation rather than as a problem resolved by the reported experiments.

References

The framework's effectiveness on multilingual corpora (particularly low-resource languages) or highly specialized domains such as code generation and legal documents remains unexplored. Future work should extend the MOSAIC benchmark and NeuroStat's evaluation to diverse cross-lingual and cross-domain settings.

The methodology: traffic-stratified benchmarking, one RL expert per weak axis, and weight-space merging, is not inherently tied to these languages or to our organization, though we leave verification on other languages and domains to future work.
