We developed a Parametric Differential Machine Learning methodology to learn DNN parametric pricers for varying model and contract parameters, with adaptive parameter sampling. We demonstrated these parametric pricers and used them for calibration for the example of specific Cheyette models for interest rate caplets. We used the inherent randomness of the process to optimize over several random replications and thus robustify the calibration. Models and instruments are given in low-code close to mathematical notation and then translated to efficient differentiable simulation and computation in TensorFlow. This is a joint work with Bernhard Hientzsch.
