Binary Spatial Random Field Reconstruction from Non-Gaussian Inhomogeneous Time-series Observations

1 code implementation7 Apr 2022 Shunan Sheng, Qikun Xiang, Ido Nevat, Ariel Neufeld

Firstly, we develop algorithms to perform approximate Likelihood Ratio Tests on the time-series observations, compressing them to a single bit for both point sensors and integral sensors.

Model-free bounds for multi-asset options using option-implied information and their exact computation

1 code implementation25 Jun 2020 Ariel Neufeld, Antonis Papapantoleon, Qikun Xiang

We consider derivatives written on multiple underlyings in a one-period financial market, and we are interested in the computation of model-free upper and lower bounds for their arbitrage-free prices.
