Detecting and Reacting on Drifts and Shifts in On-Line Data Streams with Evolving Fuzzy Systems
In this paper, we present new approaches to handle drift and shift in on-line data streams using evolving fuzzy systems (EFS), which are characterized by the fact that their structure is not fixed and not pre-determined. When dealing with drifts and shifts in data streams one needs to take into account two major issues: a) automatic detection of, and b) automatic reaction to this. To address th...
متن کاملBasic Prion Science “Spreads” Insight
Translational research used to be fun. In fact, it used to be arresting—of course, considered here in the frame of triplets and ribonucleic acids of the transfer and mRNA variety. In fact, the mind-boggling concept that someone could actually know the velocity of a ribosome trundling down a messenger RNA, like a freight car on a railway track, led me to decide at a tender age that biochemistry ...
متن کاملOriented Paradigm Shifts in Cognitive Science
An action-oriented perspective changes the role of an individual from a passive observer to an actively engaged agent interacting in a closed loop with the world as well as with others. Cognition exists to serve action within a landscape that contains both. This chapter surveys this landscape and addresses the status of the pragmatic turn. Its potential infl uence on science and the study of co...
متن کاملAlmost specification and renewality in spacing shifts
Let $(Sigma_P,sigma_P)$ be the space of a spacing shifts where $Psubset mathbb{N}_0=mathbb{N}cup{0}$ and $Sigma_P={sin{0,1}^{mathbb{N}_0}: s_i=s_j=1 mbox{ if } |i-j|in P cup{0}}$ and $sigma_P$ the shift map. We will show that $Sigma_P$ is mixing if and only if it has almost specification property with at least two periodic points. Moreover, we show that if $h(sigma_P)=0$, then $Sigma_...
متن کاملThe prion dilemma confounding science educators
In this paper, the issue of the prion hypothesis, a simmering controversy within the scientific community, is addressed. We inquire into the appropriateness of the use of certain augmentations and rhetoric approaches used during scientific debates, as well as the aptness of unequivocal statements in textbooks that indicate "abnormal prions" as a primary cause of Transmissible Spongiform Encepha...
