Title: Multi-task language model-oriented meta-knowledge fine tuning method and platform
Inventor: HONGSHENG WANG
IPC: G06N5/04
Filed: 2020-12-21
Abstract: A multi-task language model-oriented meta-knowledge fine tuning method and a platform. On the basis of cross-domain typical fractional learning, the method obtains highly transferable common knowledge on different data sets of similar tasks, i.e. meta-knowledge, mutually correlates and mutually strengthens learning processes of similar tasks in different domains corresponding to different data sets, thereby improving fine tuning effects of similar downstream tasks on data sets in different domains in language model applications, and improving parameter initialization abilities and generalization abilities of universal language models for similar tasks. The method is to fine tune a cross-domain data set of downstream tasks. Effects of a compression model obtained by means of fine tuning are not limited to a specific data set of such tasks. On the basis of a pre-training language model, the downstream tasks are fine tuned by means of using a meta-knowledge fine tuning network to obtain a language model of similar downstream tasks independent of data sets.

IPC: H04N1/10
Filed: 1985-09-12
Abstract: A method and apparatus for registering the halftone color separation films used in color picture processing. A digital picture is taken of two register points on each separation film, and the pictures (which may contain register marks) are analyzed by algorithmic processes in order to calculate the movement necessary to register the halftone picture details (or register marks). Based on the calculations, the films are punched to provide a pair of register holes in each film at locations which result in registration when the register holes are aligned on register pins during the final reproduction process. The algorithmic process involves determining the halftone screen angle, average interdot spacing and fractional area occupied by each halftone dot within its halftone cell and using this data to construct a continuous tone picture. Interpolation techniques are used to interpolate the continuous tone picture to a registration picture which is a 150 line screen picture square with the raw data picture. Edge enhancement and tone normalization algorithms are used prior to registration. The final machine movements to achieve registration are computed from an algorithm that registers all points of the pictures from translational move data at two points.
