This invention belongs to the field of medical temporal signal processing technology, specifically a method for predicting respiratory-related displacement based on attention-embedded dilated convolution. The method involves acquiring respiratory-related temporal data of the target object over continuous time; inputting this data into a trained respiratory-related displacement temporal prediction network model, which outputs the predicted respiratory displacement. The network model comprises multiple cascaded dilated convolutional residual blocks and a prediction layer. Each dilated convolutional residual block includes a causal dilated convolutional unit, a self-attention mechanism unit, and a residual connection unit. The output of the last dilated convolutional residual block is input into the prediction layer, which outputs the respiratory-related displacement of the target object at future time points. This invention dynamically weights key time steps during each layer's temporal feature extraction process, thereby improving the predictive ability for respiratory-related displacement and tumor motion.

The invention belongs to the field of database maintenance, and discloses a method and a related system for rapid data statistics of industrial time series data, which realize standardization and structuring of statistical logic by analyzing a customer data statistical request, extracting a tag name and a statistical task. Semantic differences of different databases in the aspects of statistical functions, aggregation rules, time window definitions and the like are avoided, and statistical tasks can be executed in a unified logic model. According to the method, the statistical task is divided into a plurality of time periods according to the time region, so that the system can independently execute statistical operation in different time windows. The sectional calculation not only improves the parallel calculation efficiency, but also avoids the deviation caused by different time index precisions of the bottom layer of the database, and effectively ensures the consistency and comparability of statistical results.
