Limits on spin-dependent WIMP-proton cross-sections using the DRIFT-IId directional dark matter detector [PDF]

, 2011
The nature of dark matter remains one of the biggest questions in physics today. Weakly Interacting Massive Particles (WIMPs) are a particularly well motivated candidate for the missing matter that makes up 85% of the mass of the Universe.

Combining similarity in time and space for training set formation under concept drift [PDF]

, 2011
Concept drift is a challenge in supervised learning for sequential data. It describes a phenomenon when the data distributions change over time. In such a case accuracy of a classifier benefits from the selective sampling for training.

Fast and accurate business process drift detection [PDF]

, 2015
Business processes are prone to continuous and unexpected changes. Process workers may start executing a process differently in order to adjust to changes in workload, season, guidelines or regulations for example.

Concept Drift Detection Delay Index [PDF]

, 2023
Data streams may encounter data distribution changes, which can significantly impair the accuracy of models. Concept drift detection tracks data distribution changes and signals when to update models.

Do Arctic waders use adaptive wind drift? [PDF]

, 2004
We analysed five data sets of flight directions of migrating arctic waders in relation to winds, recorded by tracking radar and optical range finder, in order to find out if these birds compensate for wind drift, or allow themselves to be drifted by ...

A Comprehensive Survey on Concept-Drift-Resilient Network Intrusion Detection Systems

IEEE Access
The evolution of computer networks for service provision, through new devices and architectures, renders past traffic patterns obsolete. The shift in the statistical properties of data is known as concept drift (CD) and is bound to affect automated ...

Mean drift forces on arrays of bodies due to incident long waves [PDF]

, 1986
The scattering of long water waves by an array of bodies is investigated using the method of matched asymptotic expansions. Two particular geometries are considered, these are a group of vertical cylinders extending throughout the depth and a group of ...

An Automatic Drift-Measurement-Data-Processing Method with Digital Ionosondes

Remote Sensing, 2022
Drift detection is one of the important detection modes in a digital ionosonde system. In this paper, a new data processing method is presented for boosting the automatic and high-quality drift measurement, which is helpful for long-term ionospheric ...
