 Vector search is an information retrieval method that has been growing in popularity over the past few  years, partly because of the rising importance of multimedia embeddings created from unstructured data and the need to perform semantic search on the embeddings to find items which are semantically similar to each other.
 
-Vector search is also used in _data mining and machine learning_ tasks and comprises an important step in many _clustering_ and _visualization_ algorithms like [UMAP](https://arxiv.org/abs/2008.00325), [t-SNE](https://lvdmaaten.github.io/tsne/), K-means, and [HDBSCAN](https://hdbscan.readthedocs.io/en/latest/how_hdbscan_works.html).
