SNLI-VE Models

Fasttext hypothesis only baseline

Run scripts/create_fasttext_datasets.py to generate files for fasttext. Run scripts/create_snli_hard.py to create hard dataset splits.

Train fasttext model and make predictions:

fasttext supervised -input fasttext_train.txt -ouput fasttext_hyp_only -wordNgrams 2
fasttext predict fasttext_hyp_only.bin fasttext_<split>.txt 1 > prediction_<split>.txt 

Detectron bounding boxes for ROI Attention models

Run inference for bounding boxes:

DETECTRON=/path/to/detectron
SNLIVE=/path/to/SNLI-VE
python $DETECTRON/tools/infer_snlive.py \
    --cfg $DETECTRON/configs/12_2017_baselines/e2e_mask_rcnn_R-50-FPN_2x.yaml \
    --output-dir $SNLIVE/data/detectron \
    --output-ext json \
    --image-ext jpg \
    --wts $DETECTRON/weights/e2e_mask_rcnn_R-50-FPN_2x_model.pkl \
    $SNLIVE/data/flickr30k-images

The custom detection script can be found in scripts/infer_snlive.py

SNLI-VE training and inference

Create smaller data subsets for training runs scripts/subset_snli_ve_data.py

Training:

allennlp train experiments/<EXPERIMENT_NAME>.json \
    --serialization-dir models/<EXPERIMENT_NAME> \
    --include-package snli_ve

Evaluation for fusion models:

allennlp predict \
    --output-file data/predictions/<OUTPUT>.json \
    --silent \
    --cuda-device -1 \
    --predictor snlive_fusion_predictor \
    --include-package snli_ve \
    models/<EXPERIMENT_NAME>/model.tar.gz \
    data/snli_ve_<SPLIT>.jsonl

Evaluation for ROI Attention models:

allennlp predict \
    --output-file data/predictions/<OUTPUT>.json \
    --silent \
    --cuda-device -1 \
    --predictor snlive_roi_predictor \
    --include-package snli_ve \
    models/<EXPERIMENT_NAME>/model.tar.gz \
    data/snli_ve_<SPLIT>.jsonl
