The main goal of embedding algorithms is usually to produce embeddings where items that are similar in the original data set are embedded into vectors that lie close to each other in the embedding space. This makes embeddings highly suitable as input for computational analysis tasks such as clustering, classification, and similarity calculations since it is often more straightforward to perform these calculations on numeric vectors than rather than on the underlying data. For some data types, such as graphs\/networks and words\/text, there exist several different algorithms (each with its specific characteristics and tradeoffs) and therefore choosing the best embedding technology for a given application is an important and often non-trivial task. However, searching for single candidates is not the only strategy that could be used\u2013and therefore this presentation will contain examples and results (some published, and some work-in-progress) aiming to answer the research question \u201c<em>Is it possible to combine several different embeddings to obtain even better results and visualizations?<\/em>\u201d<\/p>\n<p>More information about Daniels research project <a href=\"https:\/\/lnu.se\/en\/research\/research-projects\/doctoral-project-multivariate-network-embedding-for-visual-analytics\/\">https:\/\/lnu.se\/en\/research\/research-projects\/doctoral-project-multivariate-network-embedding-for-visual-analytics\/\u00a0<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When?
