Abstract

In a natural market environment, the price prediction model needs to be updated in real time according to the data obtained by the system to ensure the accuracy of the prediction. In order to improve the user experience of the system, the price prediction function needs to use the fastest training model and the model prediction fitting effect of the best network as a predictive model. We conduct research on the fundamental theories of RNN, LSTM, and BP neural networks, analyse their respective characteristics, and discuss their advantages and disadvantages to provide a reference for the selection of price-prediction models.

Complexity vs Empirical Score

  • Math Complexity: 3.5/10
  • Empirical Rigor: 2.0/10
  • Quadrant: Philosophers — conceptual discussion, limited math and data

Why this score: The paper discusses neural network architectures with moderate equations but lacks detailed implementation code or backtesting results, focusing more on theoretical comparison than empirical validation.
