This repository includes the implementation for Adaptively Aligned Image Captioning via Adaptive Attention Time.

• Python 3.6
• Java 1.8.0
• PyTorch 1.0
• cider
• coco-caption
• tensorboardX

See details in data/README.md.

(notes: Set word_count_threshold in scripts/prepro_labels.py to 4 to generate a vocabulary of size 10,369.)

You should also preprocess the dataset and get the cache for calculating cider score for SCST:

$ python scripts/prepro_ngrams.py --input_json data/dataset_coco.json --dict_json data/cocotalk.json --output_pkl data/coco-train --split train

$ sh train-aat.sh

See opts.py for the options.

$ CUDA_VISIBLE_DEVICES=0 python eval.py --model log/log_aat_rl/model.pth --infos_path log/log_aat_rl/infos_aat.pkl  --dump_images 0 --dump_json 1 --num_images -1 --language_eval 1 --beam_size 2 --batch_size 100 --split test
