AraT5-base

AraT5-base is one of three models described in our AraT5: Text-to-Text Transformers for Arabic Language Understanding and Generation . In this paper, we introduce three powerful Arabic-specific text-to-text transformer models trained on large Modern Standard Arabic (MSA) and/or Dialectal Arabic (DA) data. AraT5 is trained on 248GB of text (29B tokens) of MSA and DA, AraT5-msa is trained on 70GB of text (7.1B tokens) from MSA data, and AraT5-tweet is trained on 178Gb of text (21.9B tokens) from 1.5B Arabic tweets which contains multiple varieties of dialectical Arabic.

In addition, we provide the three models on two architectures small and base. For all models, we use a learning rate of 0.01, a batch size of 128 sequences, and a maximum sequence length of 512 whereas AraT5-tweet 128 maximum sequence is used. Hence, the original implementation of T5 in the TensorFlow framework is used to train the models. We train the models for 1M steps.8 Training took ∼ 80 days on 1 on Google Cloud TPU with 8 cores (v3.8) from TensorFlow Research Cloud (TFRC).

How to use AraT5 models

This is an example for fine-tuning AraT5-base for News Title Generation on the Aranews dataset

In addition, we release the fine-tuned checkpoint of the News Title Generation (NGT) which is described in the paper. The model available at Huggingface (UBC-NLP/AraT5-base-title-generation).
