It was first released in 12 [this repository](https://github.com/agemagician/CodeTrans). This model is trained on tokenized csharp code functions: it works best with tokenized csharp functions. 13 14 15 ## Model description 16 17 This CodeTrans model is based on the t5-base model. It has its own SentencePiece vocabulary model. It used transfer-learning pre-training on 7 unsupervised datasets in the software development domain. It is then fine-tuned on the source code summarization task for the csharp code snippets. 18 19 20 21 ## Intended uses & limitations 22 23 The model could be used to generate the description for the csharp function or be fine-tuned on other csharp code tasks. It can be used on unparsed and untokenized csharp code. However, if the csharp code is tokenized, the performance should be better. 24 25 ### How to use 26 27 Here is how to use this model to generate csharp function documentation using Transformers SummarizationPipeline: 28 29 python 30 from transformers import AutoTokenizer, AutoModelWithLMHead, SummarizationPipeline 31 32 pipeline = SummarizationPipeline( 33 model=AutoModelWithLMHead.from_pretrained("SEBIS/code_trans_t5_base_source_code_summarization_csharp_transfer_learning_finetune"), 34 tokenizer=AutoTokenizer.from_pretrained("SEBIS/code_trans_t5_base_source_code_summarization_csharp_transfer_learning_finetune", skip_special_tokens=True), 35 device=0 36 ) 37 38 tokenized_code = "public static DateTime ParseUnixDateTime ( double unixTime ) { var dt = new DateTime ( CODE_INTEGER , CODE_INTEGER , CODE_INTEGER , CODE_INTEGER , CODE_INTEGER , CODE_INTEGER , CODE_INTEGER , System . DateTimeKind . Utc ) ; dt = dt . AddSeconds ( unixTimeStamp ) . ToLocalTime ( ) ; return dt ; }" 39 pipeline([tokenized_code]) 40  41 Run this example in [colab notebook](https://github.com/agemagician/CodeTrans/blob/main/prediction/transfer%20learning%20fine-tuning/source%20code%20summarization/csharp/base_model.ipynb). 42 ## Training data 43 44 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) 45 46 47 ## Training procedure 48 49 ### Transfer-learning Pretraining 50 51 The model was trained on a single TPU Pod V3-8 for 500,000 steps in total, using sequence length 512 (batch size 4096). 52 It has a total of approximately 220M parameters and was trained using the encoder-decoder architecture. 53 The optimizer used is AdaFactor with inverse square root learning rate schedule for pre-training. 54 55 ### Fine-tuning 56 57 This model was then fine-tuned on a single TPU Pod V2-8 for 500 steps in total, using sequence length 512 (batch size 256), using only the dataset only containing csharp code. 58 59 60 ## Evaluation results 61 62 For the source code summarization tasks, different models achieves the following results on different programming languages (in BLEU score): 63 64 Test results : 65 66 | Language / Model | Python | SQL | C# | 67 | -------------------- | :------------: | :------------: | :------------: | 68 | CodeTrans-ST-Small | 8.45 | 17.55 | 19.74 | 69 | CodeTrans-ST-Base | 9.12 | 15.00 | 18.65 | 70 | CodeTrans-TF-Small | 10.06 | 17.71 | 20.40 | 71 | CodeTrans-TF-Base | 10.94 | 17.66 | 21.12 | 72 | CodeTrans-TF-Large | 12.41 | 18.40 | 21.43 | 73 | CodeTrans-MT-Small | 13.11 | 19.15 | 22.39 | 74 | CodeTrans-MT-Base | **13.37** | 19.24 | 23.20 | 75 | CodeTrans-MT-Large | 13.24 | 19.40 | **23.57** | 76 | CodeTrans-MT-TF-Small | 12.10 | 18.25 | 22.03 | 77 | CodeTrans-MT-TF-Base | 10.64 | 16.91 | 21.40 | 78 | CodeTrans-MT-TF-Large | 12.14 | **19.98** | 21.10 | 79 | CODE-NN | -- | 18.40 | 20.50 | 80 81 82 > Created by [Ahmed Elnaggar](https://twitter.com/Elnaggar_AI) | [LinkedIn](https://www.linkedin.com/in/prof-ahmed-elnaggar/) and Wei Ding | [LinkedIn](https://www.linkedin.com/in/wei-ding-92561270/) 83 84 85
