    Facial Expression Recognition Based on Dense Connected Convolution Structure
    MA Jin-feng
    Computer & Telecommunication. 2021, 1 (4): 1-5.   DOI: 1008-6609(2021)04-0001-05
    Face expression recognition is an important branch of image processing and a hot topic in computer vision research. Thetraditional convolutional neural network improve the accuracy of the network by deepening the number of network layers and ex-panding the scale of model parameters, but compared with the traditional machine learning algorithm, its accuracy has not been sig-nificantly improved. For this reason, inspired by DenseNet, a network model M-Densenet is designed, which is specifically appliedto facial expression recognition. This model is used to conduct experiments on Fer2013gray expression recognition data set. The ex-perimental results show that the model is used to conduct experiments on Fer2013gray expression recognition data set. With a highaccuracy rate of70.45%, compared with the traditional convolutional neural network, the number of parameters of the model is low-er and the utilization rate of model parameters is higher.

    DENG Rui WEI Sheng-nan
    Computer & Telecommunication. 2021, 1 (4): 66-73.   DOI: 1008-6609(2021)04-0066-08
    : In the sewage treatment process, one of the important steps is to predict the sewage quality, so that we can understand the changes of the sewage quality. In order to obtain more accurate water quality prediction results, the collected historical sewage data of a sewage treatment plant is first normalized and missing values is filled, etc., and select seven indicators such as ORP (OxidationReduction Potential), DO (Dissolved Oxygen), pH as input variables; then use the DBSCAN(Density-Based Spatial Clustering of Applications with Noise) algorithm to obtain the clustered sewage data, thus the similar sewage data are grouped into one category; finally, the LSTM neural network model is used to predict the values of the Chemical Oxygen Demand (COD), Ammonia Nitrogen (NH4N) and Total Phosphorus (TP), so as to know the changes of water quality. The experimental results show that the Root Mean Square Error (RMSE) value and Mean Absolute Error (MAE) value of the prediction results are both small, and the predicted values are close to the actual values, the prediction results are more accurate.
