    Prediction of coalbed methane productivity based on neural network models by JIN Yi, ZHENG Chenhui, SONG Huibo, MA Jiaheng, YANG Yunhang, LIU Shunxi, ZHANG Kun, NI Xiaoming

    Published 2025-01-01
    “…Finally, according to the classification results, combined with the actual drainage data, the BP and LSTM neural network algorithms were used to predict the daily gas production of CBM wells.ResultsThe results show that: (1) Based on the grey correlation method model analysis, 10 parameters such as permeability, gas saturation and reservoir pressure gradient in the study area are the key factors affecting the gas production performance of coalbed methane; (2) Using fuzzy mathematics evaluation method to evaluate the enrichment of coalbed methane, the gas production effects of 34 wells in the study area is divided into three categories: favorable area, relatively favorable area and unfavorable area. (3)A coal reservoir daily gas production prediction model was established based on the LSTM algorithm, with a prediction error value between 4.06% and 14.79%, and the average error value of 11.09%. …”

    Abnormal event detection based on local topology and l<sub>1/2</sub>norm regularize by Qing YU, Ken CHEN, Meng LI, Fei LI

    Published 2018-10-01
    “…A new dictionary learning method was proposed by introducing a local topology term to describe structural information of video events and using the l<sub>1/2</sub>norm as the sparsity constraint to the representation coefficients based on the traditional analysis dictionary learning method.In feature extraction,a histogram of interaction force(HOIF) containing rich motion information and a histogram of oriented gradient(HOG) containing texture information were merged.Then,the improved dictionary was used to train the feature data.Finally,the reconstruction error of the testing sample under the dictionary was used to determine whether the testing sample was an abnormal sample.Experiments on UMN show the high performance of the algorithm.Compared with the state-of-the-art algorithms,the analysis dictionary classification algorithm based on local topology and l<sub>1/2</sub>norm has made more effective detection on the abnormal events in the crowd.…”
