Bangla FastText Model

This is a FastText pre-trained model for the Bengali language.

This model is build for bnlp package.

Datasets

• Wikipedia dump datasets

Training Details

• Fasttext trained with total words = 20M, vocab size = 1171011, epoch=50, embedding dimension = 300

Evaluation Details

• training loss = 0.318668

Usage

• pip install -U bnlp_toolkit
• pip install fasttext==0.9.2
• Generate Vector Using Pretrained Model

from bnlp.embedding.fasttext import BengaliFasttext

bft = BengaliFasttext()
word = "গ্রাম"
model_path = "bengali_fasttext_wiki.bin"
word_vector = bft.generate_word_vector(model_path, word)
print(word_vector.shape)
print(word_vector)

• Train Bengali FastText Model

from bnlp.embedding.fasttext import BengaliFasttext

bft = BengaliFasttext()
data = "raw_text.txt"
model_name = "saved_model.bin"
epoch = 50
bft.train(data, model_name, epoch)

• Generate Vector File from Fasttext Binary Model

from bnlp.embedding.fasttext import BengaliFasttext

bft = BengaliFasttext()

model_path = "mymodel.bin"
out_vector_name = "myvector.txt"
bft.bin2vec(model_path, out_vector_name)
