Build k-Nearest Neighbor (k-NN) similarity search engine with Amazon Elasticsearch Service

By GIXnews

Amazon Elasticsearch Service now offers k-Nearest Neighbor (k-NN) search which can enhance search by similarity use cases like product recommendations, fraud detection, and image, video and semantic document retrieval. Built using the lightweight and efficient Non-Metric Space Library (NMSLIB), k-NN enables high scale, low latency nearest neighbor search on billions of documents across thousands of dimensions with the same ease as running any regular Elasticsearch query.
