Abstract: Disclosed herein is a document image analysis apparatus including: a document image acquisition unit configured to acquire a document image; a region detection unit configured to detect a plurality of regions from the document image acquired by the document image acquisition unit; a clustering unit configured to cluster the plurality of regions detected by the region detection unit to integrate into a cluster; and a reading order assignment unit configured to assign a reading order to a plurality of regions belonging to the cluster within the cluster integrated by the clustering unit.

Abstract: Disclosed herein is an information processing apparatus including: a training data acquisition unit configured to acquire training data; an input channel setting unit configured to set a plurality of input channels for inputting different features, respectively, from the training data acquired by the training data acquisition unit to a learning model to be trained with the training data; and a training unit configured to, in each training, randomly select, among the plurality of input channels set by the input channel setting unit, at least a part of the input channels, and deactivate an input from the selected input channel to the learning model to repeat training of the learning model.

Abstract: A user interface apparatus, computer program, computer readable medium, and method for selecting a selectable object on a display screen is presented. The display screen displays one or more selectable objects. Information regarding a tracked hand position, and a tracked head or eye position of the user are obtained. Based on the tracked hand position and the tracked head or eye position, it is determined whether a said selectable object is located at a first screen position, the first screen position being a position on the display screen such that the first hand at least partly obscures the user's view of the selectable object. If it is determined as so located, then selectable object is determined as selected.
