The invention discloses a price
trend prediction method for bulk commodities whose prices are in an oscillation environment for a long time, and relates to the technical field of
data analysis, and the method comprises the steps: obtaining historical data; based on the historical data, constructing a
time sequence prediction model of a multi-dimensional time dimension and a
machine learning prediction model, obtaining a corresponding
time sequence prediction result through the
time sequence prediction model of the multi-dimensional time dimension, and obtaining a
machine learning prediction result through the
machine learning prediction model; and taking the minimum variance of the prediction result as an optimization target, obtaining corresponding weight parameters of the time
sequence prediction model and the
machine learning prediction model of the multi-dimensional time dimension by applying a constraint optimization
algorithm, and combining all prediction results based on the corresponding weight parameters to form a target prediction price. According to the method, multiple prediction models are creatively fused, analysis support is provided for final price
trend prediction from multiple dimensions, and the model accuracy is greatly improved.
