BP Neural Network Based On The Forecast Of The Price Of Pig Prices In North And South

These years, with the development of society,The pig industry in our country is very unstable.The reason for the situation is that: first of all, for the frequent safety accidents;Followed by the unceasing change of supply and demand;Again for pork prices or high and low volatility.For pork market participants, pig price is very important to accurately predict the future.The importance is mainly reflected in:pig producers can be per-arranged plans for future production, reduce the risk of pig price change brings to the production and business operation;Pork processors can choose reasonable purchasing plan, cost savings; Relevant departments can according to the prediction results to evaluate pork market risk, thus reasonable arrangement of market operation. Both for scientific guidance production of live pigs, or for pork prices macroeconomic regulation and control, must use scientific prediction for pig price cycle.In the collection, summarization and research on the historical data, on the basis of the author with the aid of the BP neural network prediction method, realized the operation in MATLAB.In choosing the 6 cases of hidden layer neurons, by means of model training for many times, achieved the expected result.
