It’s composed of four transformers: Image -> Embedding, Text -> Embedding, Embedding -> Text, Image -> Text. With all these, transformations we can translate text to image and visa-versa using a embedding as an intermediate representation.

[NeurIPS’19] Previous text embeddings (e.g., Word2Vec) are trained in the Euclidean space But used on spherical space—Mostly directional similarity (i.e., cosine similarity) Word similarity is derived using cosine similarity WebJun 9, 2024 · Word embedding aims to represent each word with a dense vector which reveals the semantic similarity between words. Existing methods such as word2vec derive such representations by factorizing the word–context matrix into two parts, i.e., word vectors and context vectors. However, only one part is used to represent the word, which …
WebTo address this issue, we define and construct a dual-geometric space embedding model (DGS) that models two-view KGs using complex non-Euclidean geometric spaces for different portions of the graph. DGS utilizes the spherical space, hyperbolic space, and their intersecting space in a unified framework for learning embeddings.
