Class Embedding

java.lang.Object
dev.langchain4j.data.embedding.Embedding
public class Embedding extends Object
Represents a dense vector embedding of a text. This class encapsulates a float array that captures the "meaning" or semantic information of the text. Texts with similar meanings will have their vectors located close to each other in the embedding space. The embeddings are typically created by embedding models.
