# CodeTrans model for code documentation generation java |
|
Pretrained model on programming language java using the t5 large model architecture. It was first released in |
|
[this repository](https://github.com/agemagician/CodeTrans). This model is trained on tokenized java code functions: it works best with tokenized java functions. |
|
|
|
|
|
## Model description |
|
|
|
This CodeTrans model is based on the `t5-large` model. It has its own SentencePiece vocabulary model. It used multi-task training on 13 supervised tasks in the software development domain and 7 unsupervised datasets. It is then fine-tuned on the code comment generation task for the java function/method. |
|
|
|
## Intended uses & limitations |
|
|
|
The model could be used to generate the description for the java function or be fine-tuned on other java code tasks. It can be used on unparsed and untokenized java code. However, if the java code is tokenized, the performance should be better. |
|
|
|
### How to use |
|
|
|
Here is how to use this model to generate java function documentation using Transformers SummarizationPipeline: |
|
|
|
```python |
|
from transformers import AutoTokenizer, AutoModelWithLMHead, SummarizationPipeline |
|
|
|
pipeline = SummarizationPipeline( |
|
model=AutoModelWithLMHead.from_pretrained("SEBIS/code_trans_t5_large_code_comment_generation_java_multitask_finetune"), |
|
tokenizer=AutoTokenizer.from_pretrained("SEBIS/code_trans_t5_large_code_comment_generation_java_multitask_finetune", skip_special_tokens=True), |
|
device=0 |
|
) |
|
|
|
tokenized_code = "protected String renderUri ( URI uri ) { return uri . toASCIIString ( ) ; }" |
|
pipeline([tokenized_code]) |
|
``` |
|
Run this example in [colab notebook](https://github.com/agemagician/CodeTrans/blob/main/prediction/multitask/fine-tuning/code%20comment%20generation/large_model.ipynb). |

## Training data |
|
|
|
The supervised training tasks datasets can be downloaded on [Link](https://www.dropbox.com/sh/488bq2of10r4wvw/AACs5CGIQuwtsD7j_Ls_JAORa/finetuning_dataset?dl=0&subfolder_nav_tracking=1) |

|
## Training procedure |
|
|
|
### Multi-task Pretraining |
|
|
|
The model was trained on a single TPU Pod V3-8 for 260,000 steps in total, using sequence length 512 (batch size 4096). |
|
It has a total of approximately 220M parameters and was trained using the encoder-decoder architecture. |
|
The optimizer used is AdaFactor with inverse square root learning rate schedule for pre-training. |
|
|
|
### Fine-tuning |
|
|
|
This model was then fine-tuned on a single TPU Pod V3-8 for 25,000 steps in total, using sequence length 512 (batch size 256), using only the dataset only containing java code. |
|

|
|
## Evaluation results |
|
|
|
For the code documentation tasks, different models achieves the following results on different programming languages (in BLEU score): |
