Abstract: The current document is directed to methods and systems that effectively and efficiently employ incomplete training data to train machine-learning-based systems. Incomplete training data, as one example, may include training data with erroneous or inaccurate input-vector/label pairs. In currently disclosed methods and systems, Incomplete training data is mapped to loss classes based on addition training-data information and specific, different additional-information-dependent loss-generation methods are employed for training data of different loss classes during machine-learning-based-system training so that incomplete training data can be effectively and efficiently used.

Abstract: The present disclosure includes a system for generating a presentation order from a document that has fixed presentation layout when rendered. Techniques include reconstructing structural information and logical ordering for fixed-layout documents. A document editor generates a presentation order, or a read order, for contents within a fixed-layout document. The document editor creates an initial sort order for areas of content within a document. The document editor then generates a presentation order based on graphical dimensions and graphical placement relationships among areas of content within a document. The resulting presentation order can be used to create a second document or second layout, or to add structural information to create reflowed or reflowable content.
