Publication number: 20240104809Abstract: Embodiments described herein provide systems and methods for multimodal layout generations for digital publications. The system may receive as inputs, a background image, one or more foreground texts, and one or more foreground images. Feature representations of the background image may be generated. The foreground inputs may be input to a layout generator which has cross attention to the background image feature representations in order to generate a layout comprising of bounding box parameters for each input item. A composite layout may be generated based on the inputs and generated bounding boxes. The resulting composite layout may then be displayed on a user interface.Type: ApplicationFiled: January 30, 2023Publication date: March 28, 2024Inventors: Ning Yu, Chia-Chih Chen, Zeyuan Chen, Caiming Xiong, Juan Carlos Niebles Duque, Ran Xu, Rui Meng

Publication number: 20240077844Abstract: Systems and methods for automated workflow include assigning a set of first targets to an uncompiled first workflow. The uncompiled first workflow specifies a first set of process modules. Each such module is associated with a subset of unit operations. Each unit operation includes a time interval and specifies an instrument. For each target in the set of first targets, the uncompiled workflow is translated into an instance of a compiled first workflow that includes a linear temporal order of unit operations. This translating resolves a branch condition, nested condition, or loop condition of the uncompiled first workflow.Type: ApplicationFiled: November 3, 2023Publication date: March 7, 2024Inventors: Ran Chao, Jing Jiang, Shaoyu Meng
