Questions & Discussion¶

Key questions addressed during the presentation:

1. Q: How do you handle the infinite activity of Lévy processes?

   • A: We use truncation with controlled error bounds and adaptive mesh refinement

2. Q: What about American options?

   • A: We demonstrated Least Squares Monte Carlo adapted for Lévy processes

3. Q: Can this scale to portfolio level?

   • A: Yes, with proper parallelization and GPU acceleration

Future Work¶

Directions for extending this research:

• Multi-dimensional Lévy processes

• Machine learning for parameter calibration

• Real-time risk management applications

• Integration with high-frequency data

• R/Finance conference organizers

• Illinois Institute of Technology

• Open-source R community

• Financial data providers
