For example, in web search ranking, the relevance of a document given a query can be readily computed as the distance between them in that space.\u00a0With the latest GPUs from Nvidia, we are able to train our models on billions of\u00a0words.\u00a0Readers that are interested in deep learning for text processing may refer to our recent tutorial (<a class=\"invalidLink\" href=\"https:\/\/www.microsoft.com\/en-us\/research\/publication\/deep-learning-for-natural-language-processing-theory-and-practice-tutorial\/\" target=\"_self\" rel=\"noopener noreferrer\">He et al., 2014<\/a>), (<a href=\"https:\/\/www.microsoft.com\/en-us\/research\/publication\/introduction-deep-learning-natural-language-processing-tutorial-deeplearning2017-summer-school-bilbao-2\/#\">Gao 2017<\/a>).<\/div>\n<div id=\"en-usprojectsdssmdefault\" class=\"page-content\">\n<p>We released the <a href=\"https:\/\/www.microsoft.com\/en-us\/download\/details.aspx?id=52365\">predictors and trained model files <\/a>of the DSSM (also a.k.a.
