Embedding models and vector embeddings are crucial in handling vast amounts of unstructured data, particularly when dealing with modern datasets that require understanding meaning and context. These models transform unstructured data into numerical representations, enabling computers to understand, process, and analyze it more effectively. They capture the relationships and meanings within the data, allowing for tasks like question-answering, translation, and summarization. Advanced embedding models can handle multiple languages and data types such as text, images, and audio, making them important in building modern search systems that understand and retrieve relevant content using meaning rather than keywords.
