We address personalization issues of image captioning, which have not been discussed yet in previous research. For a query image, we aim to generate a descriptive sentence, accounting for prior knowledge such as the user's active vocabularies in previous documents. As applications of personalized image captioning, we tackle two post automation tasks: hashtag prediction and post generation, on our newly collected Instagram dataset, consisting of 1.1M posts from 6.3K users. We propose a novel captioning model named Context Sequence Memory Network (CSMN).

If you use this code as part of any published research, please refer the following paper.

git clone https://github.com/cesc-park/attend2u

1. Install python modules

pip install -r requirements.txt

2. Download pre-trained resnet checkpoint

cd ${project_root}/scripts
./download_pretrained_resnet_101.sh

3. Download our dataset (coming soon)

cd ${project_root}/scripts
./download_dataset.sh

4. Generate formatted dataset and extract Resnet-101 pool5 features

cd ${project_root}/scripts
./extract_features.sh

Run training script. You can train the model with multiple gpus.

python -m train --num_gpus 4 --batch_size 200

Run evaluation script. You can evaluate the model with multiple gpus

python -m eval --num_gpus 2 --batch_size 500

Comming soon!

Here are post generation examples:

We implement our model using tensorflow package. Thanks for tensorflow developers. :)

We also thank Instagram for their API and Instagram users for their valuable posts.

Additionally, we thank coco-caption developers for providing caption evaluation tools.
