Publication number: 20200012939Abstract: A neural network may be trained on a training corpus that comprises a large number of dataset-visualization pairs. Each pair in the training corpus may consist of a dataset and a visualization of the dataset. The visualization may be a chart, plot or diagram. In each dataset-visualization pair in the training corpus, the visualization may be created by a human making design choices. The neural network may be trained to predict, for a given dataset, a visualization that a human would create to represent the given dataset. During training, features and design choices may be extracted from the dataset and visualization, respectively, in each dataset-visualization pair in the training corpus. After the neural network is trained, features may be extracted from a new dataset, and the trained neural network may predict design choices that a human would make to create a visualization that represents the new dataset.Type: ApplicationFiled: May 15, 2019Publication date: January 9, 2020Inventors: Kevin Hu, Michiel Bakker, Cesar Hidalgo

Patent number: 5822503Abstract: Disclosed is a method of modifying one or more colors contained in an Encapsulated PostScript (EPS) file in a computer program such as a desktop publishing program (50). After an EPS file has been imported into a publication, all identifiable colors in the EPS file, i.e., spot colors and, in some instances, process colors, are displayed to a color palette (84). The color palette allows a user to see those colors (or inks) that are needed to print the publication, and subsequently modify the colors without having to return to the originating program that exported the EPS file. The method includes creating a publication color list that contains those colors that have been modified, generating a PostScript (PS) color table from the publication color list after the modifications are complete, and changing the attributes of those colors in the PS table while printing the publication to a file or to a printer.Type: GrantFiled: June 20, 1997Date of Patent: October 13, 1998Assignee: Adobe Systems IncorporatedInventors: Al C.
