MITRE Data Sets

To access the data please contact Juniper. Here is a PDF that explains the datasets and gives some sample challenge questions. MITRE DATA PDF


Death in physical, biological and social systems

Firms, nation states, human beings and stars all die. Do the causes of "death" in physical, biological and social systems have something in common? If yes, what is it?


Fractal-like structures in economic data

In the 1960-70s Mandelbrot showed that some economic time series have fractal-like structures, i.e. they look the same at many time scales. The existence of these structures has been debated since. Do economic time series like S&P 500 index have fractal-like structures? If yes, how fractal-like are they?


Microbial Community Data Sets

The Earth Microbiome Project EMP is a massively multidisciplinary effort to analyze microbial communities across the globe. The general premise is to characterize the Earth by environmental parameter space into different biomes and then explore these using samples currently available from researchers across the globe. All data sets are processed in the same way (DNA extraction, PCR primers, sequencing, bioinformatics), making them inter-comparable. You can explore these data sets (including some time series, and a bunch of spatial samplings) at the following link EMP Data (no need to create a login ID, just scroll down to 'Download Public Data'). If you have questions, please contact Sean Gibbons (sgibbons at uchicago dot edu).



Does Larger Memory Capacity Brings about Evolutionary Advantage?

Evolutionary game theory modeling. Agents/players on lattice or networks. A player with n-step memory has responses to all 4^n past game outcomes. Intuitively, a player with longer memory can have more sophisticated strategy, which might be used to exploit player with smaller memory capacity. Yet according to the Prisoner's Dilemma tournament organized by Axelrod, Tit-for-Tat, which can be modeled using only one-step memory, fares better than a number of sophisticated strategies invented by experts in the field of game theory. From the game theory perspective, does smaller memory capacity actually have evolutionary benefits?
