How to train

$ python src/train.py \
--gpu 0 \
--ref_vec_path crawl-300d-2M-subword.vec \
--freq_path resources/freq_count.crawl-300d-2M-subword.txt \

How to estimate (OOV) word vectors

For estimating OOV word vectors:

$ python src/inference.py \
--gpu 0 \
--model_path \
result/sum/20190625_00_57_18/model_epoch_300 \
--codecs_path resources/ngram_dic.max30.min3 \
--oov_word_path resources/oov_words.txt

For reconstructing original word embeddings:

$ python src/save_embedding.py \
--gpu 0 \
--inference \
--model_path result/sum/20190625_00_57_18/model_epoch_300
