Embeddings Explained
What a vector of meaning is and how to pick the model that makes them.
// THE TRACK
01 · START HEREEmbeddingsUnderstand what an embedding vector is, why similar meanings land close together, and where embeddings show up across AI systems.BEGINNERWords to VectorsFollow a sentence through an embedding model — tokens in, transformer layers, pooled vector out — to demystify how text becomes math.BEGINNERTraining Embedding ModelsUnderstand the training recipes — contrastive loss, Siamese networks, and fine-tuning pipelines — that teach embedding models to place similar meanings close together.INTERMEDIATEChoosing a ModelGet a decision framework — quality benchmarks, dimensions, price, and hosting — for picking the right embedding model for your project.INTERMEDIATEEmbedding DimensionsLearn what each number in an embedding vector represents and how dimension count trades off accuracy against memory and speed.INTERMEDIATEMultimodal EmbeddingsUnderstand how models like CLIP map text and images into one shared vector space, so a typed query can retrieve a matching picture.INTERMEDIATEMatryoshka EmbeddingsLearn how Matryoshka-trained embeddings let you slice a vector down to fewer dimensions for cheaper storage while keeping most of the quality.INTERMEDIATENormalizing EmbeddingsUnderstand what L2 normalization does to an embedding, why it makes dot product equal cosine similarity, and when you should apply it.INTERMEDIATEMatryoshka Representation LearningYou will understand the Matryoshka Representation Learning technique: how one model produces truncatable embeddings and why that saves storage and compute.INTERMEDIATEsentence-transformersYou will understand what sentence-transformers is, how it computes and trains text embeddings and rerankers, and why it underpins so much semantic search.INTERMEDIATEMTEB LeaderboardYou will understand what MTEB measures, how to read its leaderboard, and why the top model is rarely the right pick for your use case.INTERMEDIATE
