How to use it?
- Step 1: Putting your data in correct format. It is very important for fastText to have data in a prescribed correct format.
- Step 2: Cloning the repo. Next we need to clone the fastText repo into our notebook to use its functions.
- Step 3: Playing around with the commands.
- Step 4: Predicting using saved model.
How do you train a fastText model?
To train FastText model you will need the following:
- A local machine with a Linux operating system.
- Good internet connection.
- Updated anaconda installed.
- Optional: Better to make a separate virtual environment in anaconda named “FastText_env” or your favorite using python 3.6 or newer.
What is Bucket FastText?
The option -bucket is used to fix the number of buckets used by the model. For questions about the functionalities, please use the Facebook page (https://www.facebook.com/groups/1174547215919768) or the Google group (https://groups.google.com/forum/#!forum/fasttext-library) instead of Github issue.

What is CBOW and Skipgram?
Continuous Bag of Words Model (CBOW) and Skip-gram In the CBOW model, the distributed representations of context (or surrounding words) are combined to predict the word in the middle . While in the Skip-gram model, the distributed representation of the input word is used to predict the context .
What is the use of fastText?
According to facebookresearch/fastText: fastText is a library for efficient learning of word representations and sentence classification. The fastText project has released pre-trained word representations for 90 different languages using fastText.
Why is Facebook open-sourcing fastText?
To address this need, the Facebook AI Research (FAIR) lab is open-sourcing fastText, a library designed to help build scalable solutions for text representation and classification. Our ongoing commitment to collaboration and sharing with the community extends beyond just delivering code.
How does fastText learn weights?
During the model update, fastText learns weights for each of the n-grams as well as the entire word token. While the training for fastText is multi-threaded, reading the data in is done via a single thread. The parsing and tokenization is done when the input data is read. Let’s see how this is done in detail:
What is bag of words in fastText?
In fastText, a low dimensional vector is associated to each word of the vocabulary. This hidden representation is shared across all classifiers for different categories, allowing information about words learned for one category to be used by other categories. These kind of representations, called bag of words, ignore word order.
