VertiFuseX: Generalizable Financial Forecasting via Multi-Stream Temporal Fusion

Battle Count: 113

Highly relevant to quantitative trading. The paper directly addresses stock price prediction with algorithmic trading simulation, risk-adjusted performance metrics (Sharpe, Sortino, Max Drawdown), stress-testing under extreme regimes (COVID-19, 2022 bear market), transaction cost modeling, and real-time deployment considerations (1.5ms latency, 2.6MB footprint). The multi-market evaluation across 10 global indices and the economic validation through trading simulation make it directly applicable to quantitative trading workflows.

Moderate complexity. The architecture uses standard LSTM variants (LSTM, Bi-LSTM, St-LSTM) and a simple DNN, all well-supported in TensorFlow/Keras. The vertical fusion is implemented via concatenation and learned affine transformations (dense layers). Fixed hyperparameters reduce tuning burden. However, the multi-stream design requires careful dimension alignment (all branches to d_T=64), joint backpropagation through all branches, and proper chronological data splitting. Total 675k parameters is lightweight. Training takes ~2 minutes per index.

The paper provides detailed architecture specifications, fixed hyperparameters (Table 5), algorithm pseudocode (Algorithms 1 and 2), random seed (150), multi-seed robustness analysis (seeds 42, 101, 150), and clear data preprocessing steps.
