Words and phrases can be effectively represented as vectors in high-dimensional space using embeddings, making them a crucial tool in the field of natural language processing (NLP). Machine translation, text classification, and question answering are just a few of the many applications that can benefit from this representation’s ability to capture semantic connections between words.
However, when dealing with large data sets, the computational requirements to generate embeddings can be overwhelming. This is mainly because the construction of a large co-occurrence matrix is a prerequisite for traditional embedding approaches such as Word2Vec and GloVe. For very large documents or vocabularies, this array can become unmanageably huge.
To address the challenges of slow embedding generation, the Python community has developed FastEmbed. FastEmbed is designed for speed, minimal resource usage, and accuracy. This is achieved through its state-of-the-art embedding generation method, which eliminates the need for a co-occurrence matrix.
Instead of simply mapping words into a high-dimensional space, FastEmbed employs a technique called random projection. By using the random projection dimensionality reduction approach, it is possible to reduce the number of dimensions in a data set while preserving its essential characteristics.
FastEmbed projects words randomly into a space where they are likely to be near other words with similar meanings. This process is facilitated by a random projection matrix designed to preserve the meaning of words.
Once words are mapped to high-dimensional space, FastEmbed employs a simple linear transformation to learn the embeddings of each word. This linear transformation is learned by minimizing a loss function designed to capture semantic connections between words.
FastEmbed has been shown to be significantly faster than standard embedding methods while maintaining a high level of accuracy. FastEmbed can also be used to create embeds for large data sets while remaining relatively lightweight.
