Quantitative Models and Factor Analysis Summary Quantitative Models and Construction - **Model Name**: Multi-modal Multi-scale Stock Price Prediction Model **Model Construction Idea**: The model integrates multi-modal (chart data and time-series data) and multi-scale (different frequency data) features to enhance stock price prediction accuracy. It employs four independent deep time-series models and convolutional models for feature extraction, using both regression and classification losses for end-to-end training[14][17][18]. **Model Construction Process**: 1. **Multi-modal Features**: Combines time-series price-volume data and standardized price-volume charts. Time-series models capture abstract numerical relationships, while convolutional models identify chart patterns[17]. 2. **Multi-scale Features**: Incorporates 1-minute high-frequency data, daily data, and weekly data. High-frequency data is factorized into 55 features, which are then input into time-series models[18]. 3. **Lightweight Design**: Reduces the parameter size of each sub-model to 1/4 of the initial version, minimizing overfitting and computational resource dependency[18]. 4. **Multi-head Output**: Outputs include absolute future returns and categorical predictions (up, flat, down), using mean squared error and cross-entropy as loss functions[19]. **Model Evaluation**: The model demonstrates significant improvements in prediction accuracy and excess returns compared to the initial version[14][17][19].
