Code for paper Neural-based Noise Filtering from Word Embeddings (COLING 2016).

1. Sklearn
2. Theano

• The models can filter noise from any pre-trained word embeddings such as word2vec, GloVe
• The format of word embeddings used in this code is either word2vec or GloVe (either binary or text)

• This step is to learn the dictionaries for CompEmb and OverCompEmb models; transform complete word embeddings to overcomplete word embeddings.

• Running command:

  python preprocessing.py -input <original_embs_file> -output <overcomp_file> -factor <factor_overcomplete> -bin <format_file>

  For example, transform an input word embeddings of 100 dimensions into overcomplete word embeddings of 1000 dimensions (factor == 10) with binary format:

  python preprocessing.py -input sgns_100d.bin -output sgns_overcomp_1000d.bin -factor 10 -bin 1

1. Training CompEmb model:

```THEANO_FLAGS="mode=FAST_RUN,device=cpu,floatX=float32" python filter_noise_embs.py -input sgns_100d.bin -output sgns_denoising_100d.bin -iter 30 -bsize 100 -bin 1```

Train CompEmb model with 30 iterations, batch size of 100, and binary format.

2. Training OverCompEmb model:

```THEANO_FLAGS="mode=FAST_RUN,device=cpu,floatX=float32" python filter_noise_embs.py -input sgns_100d.bin -output sgns_denoising_1000d.bin -over sgns_overcomp_1000d.bin -iter 30 -bsize 100 -bin 1```

Train OverCompEmb model with 30 iterations, batch size of 100, and binary format; sgns_overcomp_1000d.bin is an overcomplete word embeddings.
