Build a Search Engine: Semantic Search System Using OpenSearch

PyImageSearch

In this tutorial, well explore how OpenSearch performs k-NN (k-Nearest Neighbor) search on embeddings. Each word or sentence is mapped to a high-dimensional vector space, where similar meanings cluster together. OpenSearch uses k-Nearest Neighbors (k-NN) search to find the most similar embeddings in the dataset.

Benchmarking Amazon Nova and GPT-4o models with FloTorch

AWS Machine Learning Blog

OpenAI launched GPT-4o in May 2024, and Amazon introduced Amazon Nova models at AWS re:Invent in December 2024. The implementation included a provisioned three-node sharded OpenSearch Service cluster. Retrieval (and reranking) strategy FloTorch used a retrieval strategy with a k-nearest neighbor (k-NN) of five for retrieved chunks.
