Real Synthetic Scholarship

Synthetic or Real ?

We provide a model of non-redundant credit default swaps (CDSs), building on the observation that CDSs are more liquid than bonds. CDS introduction involves a trade-o↵: It crowds out demand for the bond, but improves the bond allocation because it allows long-term investors to become levered basis traders. CDS introduction raises bond prices only when there is a significant liquidity di↵erence ...

Synthetic and Real Spatiotemporal Datasets

In the context of a spatiotemporal research environment, it is very important to be able to systematically generate data with predictable characteristics. For instance, it allows one to use the same datasets, or others similarly characterized, for benchmarking access structures or mining techniques. This paper presents a survey of existing generators of synthetic spatiotemporal data. It also co...

How Real Can Synthetic Network Traffic Be?

At some point, most networking researchers simulate or emulate networks in order to understand the behavior or performance of some piece of networking technology. In performing these experiments, there is a clear need to have the ability to generate realistic synthetic workloads; synthetic network traffic whose statistical properties match those of traffic observed on a real network link. In ou...

Integrating synthetic objects into real scenes

This paper presents a methodology for integrating synthetic objects into real scenes. We take a set of photographs of the real scene and build a simple image-based model. We use high dynamic range images to build an accurate representation of the lighting in the scene. Then we insert a synthetic object into the model and compute its illumination and shading using the lighting information. Illum...
