VLSP2021 vieCap4H Challenge: Automatic image caption generation for healthcare domains in Vietnamese
https://aihub.vn/competitions/40#participate
pip install torch torchvision torchaudio
pip install -r requirements.txt
Download the tokenizer from: tokenizer link and put it in: tokenizers folder.
Download pre-trained weights from pretrained link and put it in pretrained_models folder.
In this repo, I convert the JSON to CSV format for simple processing.
In json2txt.py, specify the caption file_path in json format, and caption destination dest_path in csv format.
The file_path will be the path to the train_captions.json or sample_submission.json or private_sample_sub.json.
The dest_path will be the path containing the generated CSV file, it is in the train_files folder. Noted that: the train_captions.json will generate train_captions.csv, the sample_submission.json will generate test_captions.csv, and the private_sample_sub.json will generate private_captions.csv.
In config.py, we specify these paths to the provided data:
train_path = '../data/viecap4h-public-train/viecap4h-public-train/'
# test_path = '../data/vietcap4h-public-test/'
test_path = '../data/vietcap4h-private-test/vietcap4h-private-test/'
tokenizer_path = './tokenizers/tokenizer_vi_fix_error_english2.pth'
prev_model = './pretrained_models/swin_fold1_epoch11_best_remove_english_292646.pth'
train_path is the path to the images_train folder of the train data.
test_path is the path to the images_public_test folder of the public test data or the images folder of the private data.
tokenizer_path is the path to the tokenizer.
prev_model is the path to the pre-trained model.
This code uses Swin Transformer (you can change to other types of Transformer) as the Encoder and LSTM Attention as the Decoder.
Run train.py to train with the train data. Make sure that you already have the tokenizer file.
To reproduce our result on the private board, please make sure to train fold 2 which is specified in config.py, and get the weight at the epoch 11.
Run inference.py. Noted that we currently dont support the ensemble version, but if you want to do it, set the ensemble parameter in config.py to True.
Achieved 0.302 BLEU4 for Public Dataset.
Achieved 0.293 BLEU4 for Private Dataset. As a result, I achived the 3rd on the leaderboard.

abstract = {This study presents our approach to automatic Vietnamese image captioning for the healthcare domain in text processing tasks of Vietnamese Language and Speech Processing (VLSP) Challenge 2021, as shown in Figure~\ref\{fig:example\}. In recent years, image captioning often employs a convolutional neural network-based architecture as an encoder and a long short-term memory (LSTM) as a decoder to generate sentences. These models perform remarkably well in different datasets. Our proposed model also has an encoder and a decoder, but we instead use a Swin Transformer in the encoder, and a LSTM combined with an attention module in the decoder. The study presents our training experiments and techniques used during the competition. Our model achieves a BLEU4 score of 0.293 on the vietCap4H dataset, and the score is ranked the 3\$^\{rd\}\$ place on the private leaderboard. Our code can be found at \url\{https://git.io/JDdJm\}.},
