CAMeLBERT-DA SA 模型

模型描述

CAMeLBERT-DA SA 模型是通过对 CAMeLBERT Dialectal Arabic (DA) 模型进行微调而构建的情感分析（SA）模型。 在微调过程中，我们使用了 ASTD 、 ArSAS 和 SemEval 数据集。 关于我们使用的微调过程和超参数可在我们的论文 *" The Interplay of Variant, Size, and Task Type in Arabic Pre-trained Language Models "中找到。

• 我们的微调代码可以在 here 中找到。

预期用途

您可以将 CAMeLBERT-DA SA 模型直接用作我们的 CAMeL Tools SA 组件的一部分（推荐）， 或将其作为 transformers pipeline 的一部分。

如何使用：

要将模型与 CAMeL Tools SA 组件一起使用：

>>> from camel_tools.sentiment import SentimentAnalyzer
>>> sa = SentimentAnalyzer("CAMeL-Lab/bert-base-arabic-camelbert-da-sentiment")
>>> sentences = ['أنا بخير', 'أنا لست بخير']
>>> sa.predict(sentences)
>>> ['positive', 'negative']

您还可以直接使用 SA 模型与 transformers pipeline：

>>> from transformers import pipeline
>>> sa = pipeline('text-classification', model='CAMeL-Lab/bert-base-arabic-camelbert-da-sentiment')
>>> sentences = ['أنا بخير', 'أنا لست بخير']
>>> sa(sentences)
[{'label': 'positive', 'score': 0.9616648554801941},
 {'label': 'negative', 'score': 0.9779177904129028}]

注意：要下载我们的模型，您需要 transformers>=3.5.0 。 否则，您可以手动下载模型。

    abstract = "In this paper, we explore the effects of language variants, data sizes, and fine-tuning task types in Arabic pre-trained language models. To do so, we build three pre-trained language models across three variants of Arabic: Modern Standard Arabic (MSA), dialectal Arabic, and classical Arabic, in addition to a fourth language model which is pre-trained on a mix of the three. We also examine the importance of pre-training data size by building additional models that are pre-trained on a scaled-down set of the MSA variant. We compare our different models to each other, as well as to eight publicly available models by fine-tuning them on five NLP tasks spanning 12 datasets. Our results suggest that the variant proximity of pre-training data to fine-tuning data is more important than the pre-training data size. We exploit this insight in defining an optimized system selection model for the studied tasks.",
