Using techniques from deep learning, we show that neural networks can be trained successfully to replicate the modified payoff functions that were first derived in the context of partial hedging by Föllmer and Leukert. Not only does this approach better accommodate the realistic setting of...

We make all decisions in the context of what we know and can envision. However, catastrophes often arise from what we had not known or had not envisioned previously. Approaches that work for addressing what can be envisioned are not useful in preventing catastrophic meltdowns arising from what...
