Abstract

The invention discloses a commodity demand prediction system based on an attention mechanism, which comprises a prediction module, a prediction display module, a hybrid neural network module, an attention mechanism module and a time sequence module. The hybrid neural network module is internally provided with a signal receiving unit, a convolutional neural network module and a recurrent neural network module. A first grabbing module and a first definition module are arranged in the convolutional neural network module, a second grabbing module and a second definition module are arranged in the recurrent neural network module, and an assignment unit and an assignment conveying unit are arranged in the attention mechanism module. A short-term feature unit, a local variable unit, a long-term feature unit and a global macroscopic variable unit are arranged in the time sequence module, and the convolutional neural network module is connected with the short-term feature unit and the local variable unit. The invention provides a hybrid neural network commodity demand prediction system based on an attention mechanism.

Description

technical field [0001] The present application relates to a forecasting system, in particular to a forecasting system for commodity demand based on an attention mechanism. Background technique [0002] The attention mechanism is an algorithm proposed in 2017 to improve the language learning ability of the language model. The attention mechanism can not only quantify the correlation between different words on a single sentence, but also quantify the correlation between different words on multiple sentences. Let the final prediction result focus more on words with strong correlation, while words with weak correlation have less influence on the final prediction result. [0003] Commodity demand forecasting is an important performance under time series forecasting. Traditional time series models such as autoregressive models, moving average models, and time series decomposition models perform poorly when dealing with multidimensional time series and long-term correlation time se...
