Researchers have developed and evaluated novel methods for learning risk-neutral densities from irregular option quotes, a task that proves challenging even with accurate pricing. Two benchmarks were used: a controlled synthetic dataset and a chronological NIFTY market dataset. While a two-component lognormal mixture model performed well on the synthetic data, learned operators like DeepONet and quote transformers showed specific strengths in reducing certain errors. The study highlights the importance of target-dependent inductive biases, as no single method universally outperformed others across all metrics and datasets. AI
