模型:
microsoft/xtremedistil-l6-h384-uncased
XtremeDistilTransformers是一个蒸馏的任务无关transformer模型,利用任务迁移学习一个小型通用模型,可应用于任意任务和语言,如 XtremeDistilTransformers: Task Transfer for Task-agnostic Distillation 论文所述。
我们利用 XtremeDistil: Multi-stage Distillation for Massive Multilingual Models 和 MiniLM: Deep Self-Attention Distillation for Task-Agnostic Compression of Pre-Trained Transformers 论文中的任务迁移和多任务蒸馏技术,具体内容见 Github code 。
此l6-h384检查点具有6个层,384个隐藏大小,12个注意力头,对应于2200万参数,比BERT-base快5.3倍。
其他可用的检查点: xtremedistil-l6-h256-uncased 和 xtremedistil-l12-h384-uncased
