Various methods for random sentence representations, from the paper No Training Required: Exploring Random Encoders for Sentence Classification.

If you don't have SentEval yet, download it:

git clone https://github.com/facebookresearch/SentEval.git

Download the evaluation data and place SentEval in the current directory, or provide the path using --senteval_path.

In the paper, we use GloVe embeddings (but nothing stops you from running RandSent with different embeddings):

wget http://nlp.stanford.edu/data/glove.840B.300d.zip

Place glove.840B.300d.txt in the current directory, or provide the path using --word_emb_path.

RandSent requires:

• Python 3
• Pytorch 1.0
• Numpy

These are some example commands:

ESN:

python -u randsent.py --model esn --pooling mean --pos_enc 0 --output_dim 2048 --zero 1 --spectral_radius 1.0 --leaky 0 --concat_inp 0 --stdv 0.1 --activation None --bidirectional 1 --sparsity 0.5 --gpu 1

Random projection (BOREP):

python -u randsent.py --model borep --pooling mean --projection same --pos_enc 0 --bidirectional 0 --output_dim 4096 --activation nn.ReLU --zero 1 --gpu 1

Random LSTM:

python -u randsent.py --model lstm --pooling mean --pos_enc 0 --bidirectional 1 --output_dim 2048 --zero 1 --num_layers 1 --activation None --gpu 1
