N was then employed to obtain the output on the complete residual structure. Completely connected layers. The characteristics of cubes-Pool2 were flattened, and by applying the fully connected layers, the cubes-Pool2 had been transformed into feature vectors with a size of 1 128.(two)(3)(4)Streptonigrin manufacturer Remote Sens. 2021, 13,10 ofLogistic regression. A logistic regression classifier was added just after the completely connected layers. Softmax was applied for several classification. Soon after flattening the capabilities Remote Sens. 2021, 13, x FOR PEER REVIEWof the input data, the probability of those attributes is often attached to each category 11 of 23 of trees.(five)Figure 9. The architecture of the 3D-Res CNN model, which consists of four convolution layers, two max pooling layers, and Figure 9. The architecture on the 3D-Res CNN model,which consists of 4 convolution layers, two max pooling layers, and two residual blocks. Conv stands for convolutional layer, ReLu stand for the rectified linear unit. for the rectified linear unit.The parameters in the model had been initialized randomly and optimized by backpropThe parameters with the model had been initialized randomly and optimized by backpropagation to lessen (-)-Irofulven Inducer network loss and complete model coaching. Just before setting the weight agation to decrease network loss and comprehensive model coaching. Before setting the weight update rule, a appropriate loss function is essential. This study adopted the mini-batch update update rule, a suitable loss function is necessary. This study adopted the mini-batch update tactic, which is appropriate for processing huge datasets. The calculation the loss function technique, that is suitable for processing huge datasets. The calculation of of the loss funcis according to the the mini-batch input, the the formula follows: tion is based onmini-batch input, and andformula is as is as follows:_ n_classesLCE (y, y) =- L (y, ) = -i=yy log(yi ) i log(y )(1) (1)exactly where y where y will be the accurate label and y may be the predicted label. y may be the predicted label. The first completely connected layer and also the convolution layers inside the network use a linear initially totally connected layer and also the convolution layers within the network use a linear The correction unit (i.e., ReLU) as the activation function, where the formula f f = = max correction unit (i.e., ReLU) because the activation function, exactly where the formula is:is:(x)(x)max (0, (0, x) [27]. ReLU extensively employed unsaturated activation function. In In terms of gradient x) [27]. ReLU is really a is often a broadly used unsaturated activation function.terms of gradient dedescent and instruction time, the efficiency ReLU is higher than other saturated activation scent and instruction time, the efficiency ofof ReLU ishigher than other saturated activation functions. The last totally connected layer utilizes the softmax activation function, as well as the sum functions. The last fully connected layer utilizes the softmax activation function, as well as the sum of your probability values of all neuron activation is 1. with the probability values of all neuron activation is 1. The network adds dropout the two completely connected layers. According to the probThe network adds dropout toto the two completely connected layers. According to the probability, the output in the neuron was 0 toto 0 to limit the interaction of hidden units, capability, the output of your neuron was set to set limit the interaction of hidden units, allow enable the to find out to discover additional robust features, and effect of effect of noise and the networknetwork a lot more robust features, and lower thereduce thenoise and o.
