Semantic Search with Multimodal Embeddings

In a world of diverse data, traditional keyword search is no longer enough to connect text, images, and audio. Modern search systems rely on multimodal embeddings to map different media types into a single, shared vector space. This course guides you through the foundational concepts of vector embeddings and semantic search. You will learn how modern machine learning models align different data modalities, enabling you to design search systems that can retrieve images using text queries or find relevant audio files based on visual content. What you'll learn: - Understand the fundamental principles of vector spaces and high-dimensional embeddings. - Map text, images, and audio into unified vector representations using modern transformer models. - Implement cross-modal search queries using Python and vector databases. - Evaluate search relevance using similarity metrics like cosine similarity. - Apply Retrieval-Augmented Generation (RAG) concepts to multimodal data pipelines. - Configure vector indexes to optimize search speed and retrieval accuracy. The course begins with core terminology and the mathematical foundations of vector spaces, then progresses to practical search pipeline design and modern vector database integration. It is designed for beginners in data science, AI, and software engineering, requiring no prior machine learning experience.
