'Sell in May and Go Away' Just Won't Go Away

Complaints that just refuse to go away.

Sell in may and go away? Learning and risk taking in nonmonotonic decision problems.

In nonmonotonic decision problems, the magnitude of outcomes can both increase and decrease over time depending on the state of the decision problem. These increases and decreases may occur repeatedly and result in a variety of possible outcome distributions. In many previously investigated sequential decision problems, in contrast, outcomes (or the probabilities of obtaining specific outcomes)...

Provably Spurious Qualitative Simulation Predictions That Just Won’t Go Away

It is known that sound and complete qualitative simulators do not exist; that is, there exist inputs which lead to ineradicable spurious behaviors, proving whose inconsistency is an undecidable task, and thus any sound qualitative simulator has to include them in its output. In this paper, we ask whether the next best thing, that is, a single sound qualitative simulator which detects and elimin...

Does Bad News Go Away Faster?

We study the relationship between content and temporal dynamics of information on Twitter, focusing on the persistence of information. We compare two extreme temporal patterns in the decay rate of URLs embedded in tweets, defining a prediction task to distinguish between URLs that fade rapidly following their peak of popularity and those that fade more slowly. Our experiments show a strong asso...
