The invention discloses a shale identification method based on improved Resnet, and the method employs an AdaGrad optimization algorithm for parameter updating, the algorithm can properly adjust the learning rate for each element of a parameter, learning is carried out at the same time, W represents a to-be-updated weight parameter, h is the sum of squares of the loss of the previous parameter with respect to the gradient, is the gradient of a loss function with respect to the weight, and is the sum of squares of the loss of the previous parameter with respect to the weight. The method is very ideal in application in a Lonmaxi shale reservoir section, the improved residual network is very suitable for being applied to image recognition, and the problem that a deep neural network cannot process image data is solved; according to the residual network identification method provided by the invention, the features after image processing are transmitted into the multi-layer perceptron to be output ...

The invention provides an environment control method, system and device, electronic equipment and a storage medium. The method comprises the steps of obtaining actually measured environment data of at least one moment including a current moment; inputting the actually measured environment data into a prediction model to obtain predicted environment data, output by the prediction model, of the next moment under each control strategy; the prediction model is determined based on sample actual measurement environment data at each moment under a sample control strategy; determining a target control strategy from the control strategies based on the operation energy consumption data under the control strategies and difference data between the predicted environment data and preset environment threshold data under the control strategies; and performing environment control based on the target control strategy. According to the method, the system, the device, the electronic equipment and the storage ...
