English(EN) Dialect Fine-Tuning Starts With Data Curation: What NVIDIA's Nemotron Recipe Shows

NVIDIA Nemotron 3.5 微调方法强调数据精选的影响

NVIDIA 详细介绍了一种为其 Nemotron 3.5 自动语音识别 (ASR) 模型进行沙特阿拉伯方言微调的方法。关键启示是,数据精选,特别是决定从语料库中丢弃哪些话语,对性能的影响比基础模型的选择更大。NVIDIA 的方法包括保留结构良好但可能存在噪声的方言数据,同时使用约 90% 的沙特阿拉伯语和 7% 的英语的加权重放混合,以防止现有语言能力的退化。 AI

影响 强调了数据质量和精选在实现 ASR 模型有效方言微调中的关键作用。
