75k diachronic English-language SVD word embeddings, 20 decades, Google Books corpus — vecs_svd300_googlengrams

75 thousand SVD embeddings from the HistWords project, trained on the Google Books N-Gram corpus (all English) divided into decades. This is a list of 20 elements, in which every element is an embedding matrix associated with a given decade, 1800-1990. Each matrix is 75 thousand vectors (rows) and 300 dimensions (columns). Note that each embedding has the same vocabulary, but when words do not appear in a given decade they appear as rows with only zero values.
