**AraT5-base** is one of three models described in our [**AraT5: Text-to-Text Transformers for Arabic Language Understanding and Generation**
](https://arxiv.org/abs/2109.12068). 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
Below is an example for fine-tuning **AraT5-base** for News Title Generation on the Aranews dataset 
``` bash
!python run_trainier_seq2seq_huggingface.py \
        --learning_rate 5e-5 \
        --max_target_length 128 --max_source_length 128 \
        --per_device_train_batch_size 8 --per_device_eval_batch_size 8 \
        --model_name_or_path "UBC-NLP/AraT5-base" \
        --output_dir "/content/AraT5_FT_title_generation" --overwrite_output_dir \
        --num_train_epochs 3 \
        --train_file "/content/ARGEn_title_genration_sample_train.tsv" \
        --validation_file "/content/ARGEn_title_genration_sample_valid.tsv" \
        --task "title_generation" --text_column "document" --summary_column "title" \
        --load_best_model_at_end --metric_for_best_model "eval_bleu" --greater_is_better True --evaluation_strategy epoch --logging_strategy epoch --predict_with_generate\
        --do_train --do_eval
```

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](https://huggingface.co/UBC-NLP/AraT5-base-title-generation)).
