Optimal Transport for Model Calibration [PDF]

SSRN Electronic Journal, 2021
We provide a survey of recent results on model calibration by Optimal Transport. We present the general framework and then discuss the calibration of local, and local-stochastic, volatility models to European options, the joint VIX/SPX calibration problem as well as calibration to some path-dependent options.

A Real-time Traffic Signal Control Strategy Under Partially Connected Vehicle Environment

Promet (Zagreb), 2019
The performance of a traffic system tends to improve as the percentage of connected vehicles (CV) in total flow increases. However, due to low CV penetration in the current vehicle market, improving the traffic signal operation remains a challenging task.

On-Wafer Calibration Algorithm for Partially Leaky Multiport Vector Network Analyzers [PDF]

, 2005
A new solution for multiport vector network analyzer calibration is presented in this paper. The error model is divided in two separate leaky halves, each of them with crosstalk terms, but without the leakage between the two sides.
