Vector embeddings, also known as word embeddings or feature embeddings, refer to the conversion of categorical variables or text into vectors of continuous values. In machine learning and natural language processing (NLP), vector embeddings translate high-dimensional data into a lower-dimensional space, making it more manageable and revealing underlying patterns in the data.
Vector embeddings are a crucial part of many machine learning and NLP tasks, as they provide a way to handle non-numeric data, such as text, by converting it into numerical form. The resulting vectors capture semantic relationships between the original data points. For instance, in word embeddings, semantically similar words are mapped to vectors close to each other in the vector space. Techniques like Word2Vec, GloVe, and FastText are commonly used to create word embeddings. Vector embeddings not only facilitate the handling of text data but also aid in uncovering insights and relationships that may not be apparent in the original high-dimensional space.
