hebrew-gpt_neo-small

基于 EleutherAI's gpt-neo 的希伯来文本生成模型。每个模型都是在TPUv3-8上进行训练的，该TPU是通过 TPU Research Cloud 计划提供给我的。

数据集

Open Super-large Crawled ALMAnaCH corpus（ALMAnaCH超大型爬行语料库）是通过使用goclassy架构对Common Crawl语料库进行语言分类和过滤而获得的大规模多语言语料库。

Conneau＆Wenzek等人在2020年创建的CC100-Hebrew数据集。该数据集是从CC-Net库的2018年1月至12月的Commoncrawl快照中处理的100个单语数据集之一。该语料库的大小为6.1G，为希伯来语。
