OBE: Outlier by Example

Outlier detection in large datasets is an important problem. There are several recent approaches that employ very reasonable definitions of an outlier. However, a fundamental issue is that the notion of which objects are outliers typically varies between users or, even, datasets. In this paper, we present a novel solution to this problem, by bringing users into the loop. Our OBE (Outlier By Exa...

Temporal Griffiths phases.

Disorder is an unavoidable ingredient of real systems. Spatial disorder generates Griffiths phases (GPs) which, in analogy to critical points, are characterized by a slow relaxation of the order parameter and divergences of quantities such as the susceptibility. However, these singularities appear in an extended region of the parameter space and not just at a (critical) point, i.e., there is ge...

Description of the FRS domain

An FRS helps in the reservation of facilities (such as tutorial rooms, hotel rooms, lecture theaters) and specific equipment. Different organizations such as academic institutions, hotels, hospitals and companies, have different physical facilities and arrangements for their reservation. Most often, users (individuals or organizations) manage their own reservations with an FRS (e.g., add, delet...
