Embodiment 1

[0019] Example 1: Recognition of the watershed and its average void ratio of a 3D gas-solid flow system based on a 2D simulation image

[0020] First, the unit of the gas-solid flow system is determined to be a single solid particle, and the problem to be dealt with only includes one system, and the mesoscale is the particle aggregate scale. There are two types of extreme mesoscale structures in this system: one is that the size of particle agglomerates is as large as the system size, that is, a fixed bed, and the corresponding dominant mechanism is that the average void ratio tends to the minimum value; the other is that the size of particle agglomerates is as small as The cell size, ie dilute phase transport, corresponds to the dominant mechanism where the rate of energy expenditure for suspending and transporting particles within a unit volume of the bed tends towards a minimum. The intermediate area between fixed bed and dilute phase transport is fluidized bed, whose stabi...

Abstract

The invention belongs to the field of artificial intelligence, and relates to a method for improving the quality of a deep learning data set and the interpretability of a model by applying a scientific methodology. The implementation process of the invention is as follows: physical systems are defined, a mesoscale model of each physical system is established, a complete physical model of a processed object is established, association between object features and physical attributes is established, a one-dimensional label is established for the object features, a training set and a test set areestablished, deep learning is used for modeling, and the training model is used for predicting and explaining the training model. Compared with an existing deep learning method, due to the fact that the method is associated with the physical model of the processed object, the method has the advantages of being small in required data set, good in interpretability of the built model and the like.

Description

technical field [0001] The invention belongs to the field of artificial intelligence and relates to a method for improving the quality of deep learning data sets and model interpretability by applying mesoscience methodology. Background technique [0002] Deep learning technology is developed from artificial neural network technology. Based on artificial neural network technology, this technology improves the network configuration and calculation algorithm by greatly increasing the number of nodes and hidden layers, and greatly improves the ability to model complex objects. However, due to the increase in the number of nodes and hidden layers and the diversity of network configurations, the number of variables has increased sharply and the complexity of the mathematical model has increased. While improving the accuracy of the model, deep learning also greatly increases the number of samples in the data set. , resulting in a significant increase in modeling time overhead and...
