The invention discloses a machine self-learning intelligent plate changing method for an edge roller. The method comprises the following steps: inputting multiple groups of samples into a machine learning neural network; the machine learning neural network performs forward calculation according to the input sample data so as to perform model training; adjusting the weight from the input layer to the hidden layer and the weight from the hidden layer to the output layer; updating the number of times of model training, judging whether the number of times of target training is reached or not, if not, returning to the above steps to continue training, and if yes, ending training, storing trained data and obtaining a trained model; in actual production, the width and thickness of glass required by production are input into the trained model to obtain the parking space, pressing and swing angle of the glass edge roller needing to be adjusted, and the glass edge roller is adjusted to obtain glass required by production; the method has the advantages that the board changing efficiency is improved, the model is continuously optimized according to historical data, the board changing result does not depend on previously stored data, and the board changing data error is small.

The proposed technology provides methods, devices and computer programs for performing data error detection and correction. It is provided a method for performing data error detection and correction. The method comprises the step S1 of providing multiple Mojette transform projections (pi,q,) obtained by applying an encoding Mojette transform on an input, or original, block of data elements or values. The method also comprises decoding S2 the multiple Mojette transform projections to form a reconstructed block of data elements or values. The method also comprises investigating S3 whether any of the decoded Mojette transform projections comprises at least one bin≠0 following generation of the reconstructed block, thus providing an indication that a data error has been detected in the reconstructed block. The method also comprises determining S4, if at least one bin≠0, a corrected reconstructed block of data elements or values based on the decoded Mojette transform projections. The proposed technology also provides devices and computer programs implementing the method.

The invention discloses a target data positioning method, a target data positioning device, a server and a computer readable storage medium. The target data positioning method includes: creating a management table to obtain a temporary data management table; in occurrence of data operation, acquiring a temporary table in the data operation; writing process data of the temporary table into the temporary data management table to enable positioning of target data according to the temporary data management table, wherein the process data includes temporary table names, namespace names, class names, operating types and operating time. By the process data written into the temporary table, the target data of any procedure in data operation can be positioned; in occurrence of errors in operation,wrong target data can be quickly positioned, and accordingly efficiency and accuracy in data positioning are improved, and the problem of data errors can be solved quickly.
