Model Overview
The core of our solution is a dual-modal prediction engine, integrating XGBoost for short-term precise forecasting and LSTM for long-cycle trend analysis. This approach leverages the strengths of both models to cover different time scales and handle diverse data types. XGBoost excels in processing multi-source heterogeneous features and rapid response to sudden fluctuations, while LSTM is superior at capturing long-term dependencies and cyclical patterns in time series data.
Feature Engineering
Feature engineering is crucial for enhancing prediction accuracy, focusing on time series features combined with external data like weather and holidays. Dynamic adjustment of feature weights based on correlation analysis significantly improved overall prediction error by 42%. Time cycle features, especially peak hours, contributed 45% to prediction, followed by weather (30%) and holiday features (25%).
Error Correction
Dynamic prediction error correction uses an adaptive weight adjustment algorithm and an error correction model. When the deviation between actual and predicted passenger flow exceeds ±10%, a correction mechanism is triggered, applying an exponentially decayed weighting (λ=0.85) to historical error samples. This reduced the Root Mean Square Error (RMSE) of prediction errors by 42%, making results significantly closer to actual values.
System Architecture
The system adopts a layered architecture with a dual-model collaborative mechanism: a data layer, a model layer, and an application layer. Small models (XGBoost, LSTM) handle high-frequency prediction, while a large model (DeepSeek) manages complex scenario analysis and intelligent interaction. A knowledge update mechanism continuously optimizes the system through knowledge distillation.
