Solutions are obtained to the relativistic equations of motion describing the trajectories of freely circulating particles in a Tokamak. For electrons or ions subjected to toroidal acceleration or deceleration or for a poloidal field changing with time, the motion lies on a toroidal drift surface whose major radius changes slowly with time and whose ...

Proceedings of the 13th annual conference companion on Genetic and evolutionary computation, 2011
Drift analysis, introduced to the field of evolutionary computation by He and Yao ten years ago, quickly became one of the strongest tools to prove upper and lower bounds on the run-times of evolutionary algorithms. It has, however, the reputation of being difficult to use, both because it relies on deeper mathematical tools and because it needs a ...

Localization of Concept Drift: Identifying the Drifting Datapoints
2022 International Joint Conference on Neural Networks (IJCNN), 2022The notion of concept drift refers to the phenomenon that the distribution which is underlying the observed data changes over time. As a consequence machine learning models may become inaccurate and need adjustment. While there do exist methods to detect concept drift, to find change points in data streams, or to adjust models in the presence of ...

A drift of the drift adjustment method [PDF]
, 2002 This paper shows why regressing the realised rates of depreciation within the exchange rate band on a given information set and conditional on (ex-post) actual no-realignment (à la drift adjustment) still encounters a Peso Problem. Such a procedure generally gives inconsistent estimates. The main reason is that the frequency of realignments in the data

Received: 27 September 2005 Revised: 28 September 2005 Accepted: 29 September 2005 I first met Claudio in Oslo around 1980. Like so many others we met because of Kristen Nygaard. At this time Claudio spent some months at the University of Oslo as a visiting scholar doing research (together with Leslie Schneider) on the practical impacts of the ‘data ...
