This paper based on the analysis of the basic meaning in data mining and the structure of decision tree uses the decision tree algorithm — C4.5 to establish a soil quality grade prediction model and combines the soil composition in Lishu to be a training sample. C4.5 algorithm also expresses the acquired knowledge by means of quantitative rules. The experiment results manifest that the expression...
With the help of MapReduce powerful parallel computing ability and good extensibility, we try to solve the bottleneck problem of traditional BP neural network in dealing with the big data for the training sets in this paper. Through the experimental data for the farmland fertilizer effect, we propose that fertilizer rate is taken as input for the neural network, and ultimately yield is taken as the...
