Abstract: A display device and an operation method of the display device are provided in the present disclosure. The display device includes a display screen a sound-generation driving module, and further includes an acoustic scanning module, arranged on a non-display side of the display screen and configured to determine a spatial contour of a space where the display device is located through acoustic scanning; a viewer position detection module, configured to detect viewer coordinates in the space where the display device is located; and a control module, configured to control the sound-generation driving module to generate sound in accordance with the spatial contour and the viewer coordinates.

Abstract: A model training system includes at least one first cluster and a second cluster communicating with the at least first cluster. The at least one first cluster is configured to acquire a sample data set, generate training data according to the sample data set, and send the training data to the second cluster; and the second cluster is configured to train a pre-trained model according to the training data sent by the at least one first cluster.

Abstract: A method for generating a cross-lingual textual semantic model includes: acquiring a set of training data that includes pieces of monolingual non-parallel text and pieces of bilingual parallel text; determining a semantic vector of each piece of text in the set of training data by inputting each piece of text into an initial textual semantic model; determining a distance between semantic vectors of each two pieces of text in the set of training data based on the semantic vector of each piece of text in the set of training data; determining a gradient modification based on a parallel relationship between each two pieces of text in the set of training data and the distance between the semantic vectors of each two pieces of text in the set of training data; and acquiring a modified textual semantic model by modifying the initial textual semantic model based on the gradient modification.
