The artificial neural network 304 is composed of a feature extraction neural network and a classification neural network, and the feature extraction neural network can stack the input signal by sequentially stacking a convolutional layer and a pooling layer. The convolution layer may include a convolution operation, a convolution filter, and an activation function. The calculation of the convolution filter is adjusted according to the matrix size 303 of the target input, but in general, a 4X4 matrix can be used. The activation function generally uses, but is not limited to, a ReLU function, a sigmoid function, and a tanh function. The pooling layer is a layer that reduces the matrix size 303 of the input, and a method of extracting a representative value by tying pixels in a specific area may be used. In general, the average value or the maximum value is often used for the calculation of the pooling layer, but is not limited thereto. The operation is performed using a square matrix, and in general, a 4X4 matrix can be used. The convolutional layer and the pooling layer are repeated alternately until the corresponding input becomes small enough while maintaining the difference. The artificial neural network 304 may have a hidden layer and an output layer. In general, the artificial neural network 304 has 6 or more hidden layers, and 10 nodes of each hidden layer are designated, but more or less may be specified in some cases. The activation function of the hidden layer uses a ReLU function, a sigmoid function, and a tanh function, but is not limited thereto. The number of output layer nodes of the fourth artificial neural network 304 may be a total of two, but is not limited thereto. The two output layer nodes may be values obtained by classifying the hand size 303 and humidity 302 , respectively. The output value may be used to generate the disinfectant spray amount 305 from the values obtained by classifying the size 303 and the humidity 302 of the corresponding hand.

The kiosk 10 may learn the artificial neural network 304 through the labels. At this time, the integrated management server 40 may learn the artificial neural network 304 through the labels.

The labels may include values obtained by classifying the size 303 and humidity 302 of the hand for determining 10,000 hand sizes 303 and humidity 302 and the corresponding disinfectant spray amount 305. have. The artificial neural network 304 may be formed by calculating a loss function by comparing the labeled training outputs obtained by inputting the labeled training inputs with the fourth labels. As the loss function, a known mean squared error (MSE), cross entropy error (CEE), etc. may be used. However, the present invention is not limited thereto, and as long as the deviation, error, or difference between the output of the artificial neural network 304 and the label can be measured, loss functions used in various artificial neural network models may be used.

Next, the kiosk 10 may optimize the artificial neural network 304 based on the comparison value. By updating the weights of the nodes of the artificial neural network so that the comparison value becomes smaller and smaller, the output of the artificial neural network corresponding to inference and the label corresponding to the correct answer can be gradually matched, and through this, the artificial neural network can determine the correct answer. It can be optimized to output close inferences. Specifically, the learning apparatus may optimize the artificial neural network by repeating the process of resetting the weight of the artificial neural network so that the loss function corresponding to the comparison value approaches the estimated value of the minimum value. A known backpropagation algorithm, stochastic gradient descent, or the like may be used for optimization of an artificial neural network. However, the present invention is not limited thereto, and a weight optimization algorithm used in various neural network models may be used.

According to an embodiment, the integrated management server 40 may acquire the disinfectant spray amount 305 based on the output value. In addition, the integrated management server 40 may transmit the obtained disinfectant spray amount 305 back to the hand sanitizer. The amount of disinfectant spraying 305 classifies the size 303 of the user's hand into 4 steps of the 1st, 2nd, 3rd, and 4th steps, and the humidity 302 of the user's hand is 1st, 2nd, and 3rd grade Classified into a total of three grades, based on the result of synthesizing the classified hand size 303 and humidity 302 may include a total amount and spray range to spray the spray liquid.

For example, step 1 of the steps indicating the size of the hand 303 is a case where the hand width is classified as XS. It can be sprayed using only the innermost spray nozzle among the spray nozzle holes. Each stage can be divided into XS, S, M, and L. For example, step 4 of the steps indicating the size 303 of the hand is a case where the hand width is classified as L. In this case, the total amount to be sprayed may be 1 ml, and the spray range is a circular shape divided into 4 steps. All of the spray nozzle holes can be used to allow for spraying. If the user's hand is larger than L, the user may instruct the user to disinfect one hand first and then the next hand using the display of the kiosk 10 . In the first, second and third grades dividing the user's hand humidity 302, the first grade means less than 30%, the second grade means less than 30% to 50%, and the third grade means 50% or more. can For example, when the humidity 302 of the hand corresponds to the first class, the total amount to be sprayed may be sprayed with a value reduced by 20 from the value based on the size of the hand 303 . In general, the 2nd class may spray a value increased by the standard amount and the 3rd class by 20% of the standard, but is not limited thereto. Considering the humidity 302 of the hand may be to adjust the concentration of the disinfectant solution that can act on the disinfection of the hand in the actual palm.
