    -Businesses can use vector search to provide semantic search, understanding the meaning behind item names, descriptions, or images to find and recommend similar items. This enhances the user experience by offering more relevant and meaningful content to users, making it easier for them to explore and discover items of interest.

  • How does the process of using vector search for a production service in enterprises look like?

    -The process involves getting embeddings for each item, building an index on Vector Search with the embeddings, and deploying the index on an index endpoint. Queries can then be run on Vector Search to find similar items by their names or other attributes, providing results within milliseconds.

  • How does the use of embeddings from BigQuery and Vertex AI Search simplify the process of creating a semantic search system?

    -BigQuery's ML.EMBED_TEXT function allows for easy generation of embeddings for text data. These embeddings can then be exported and used in Vertex AI Search to create an index for semantic search. This streamlined process simplifies the creation of a semantic search system and reduces the time and cost associated with AI service development.

  • Can you provide an example of a company that has successfully implemented vector search technology?

    -Mercari, a popular marketplace app, has successfully implemented vector search technology to show product recommendations. They were able to build and deploy the system within a month with a single person, significantly reducing the time and cost for AI service development.

Keywords

💡Vector Search

Vector search is a technology that enables the efficient and accurate retrieval of items based on their content meaning rather than just keywords. It uses embeddings, which are vector representations of data, to map similar content close together in a high-dimensional space. In the context of the video, vector search is crucial for businesses to provide relevant search results and recommendations, as seen with Google's services like Search, YouTube, and Google Play. The technology allows for semantic search, understanding the meaning behind item names, descriptions, or images, and has been deployed in production systems like Mercari's marketplace app for product recommendations.

💡Embeddings

Embeddings are numerical representations of data, such as text, images, or any content, that capture their semantic meaning in a high-dimensional vector space. They are the foundation of vector search, allowing AI to identify and locate content based on its meaning rather than relying on keywords or categories. In the video, embeddings are created by training AI with specific content, resulting in a vector that represents the essence of that content. These embeddings are then used in vector search to find and recommend items that are semantically similar to a given query, providing a more intuitive and relevant user experience.

💡AI/ML Services

AI/ML (Artificial Intelligence/Machine Learning) services refer to the applications and systems that utilize AI and machine learning algorithms to perform tasks that would typically require human intelligence.
