The “Smart” Committee: Scaling Option Pricing with k-Sparse Gated Neural Networks
A single neural network often struggles to price options accurately across every regime. Why ask a LEAPS expert to price a 0DTE call? k-Sparse Gating solves this by acting as an intelligent ‘triage’ system. By activating only the Top-k specialists from a committee of 9 regime-trained experts, we eliminate ‘model noise’ and slash GPU latency.…
