Profiling instances in noise reduction [PDF]
Knowledge-Based Systems, 2012 The dependency on the quality of the training data has led to significant work in noise reduction for instance-based learning algorithms. This paper presents an empirical evaluation of current noise reduction techniques, not just from the perspective of their comparative performance, but from the perspective of investigating the types of instances that

Quantum noise reduction techniques in KAGRA [PDF]
Eur. Phys. J. D, 74, 10 (2020), 2019 KAGRA is the first large-scale gravitational-wave detector with cryogenic test masses. Its target sensitivity is limited mostly by quantum noise in the observation frequency band owing to the remarkable reduction of thermal noise at cryogenic temperatures.

Composite Test inclusive of Benfords Law, Noise reduction and 0-1 Test for effective detection of Chaos in Rotor-Stator Rub [PDF]
Nonlinear Dynamics, 2021, 2021 Segregating noise from chaos in dynamic systems has been one of the challenging work for the researchers across the globe due to their seemingly similar statistical properties. Even the most used tools such 0-1 test and Lyapunov exponents fail to distinguish chaos when signal is mixed with noise.

Noise Reduction in Hyperspectral Imagery: Overview and Application
Remote Sensing, 2018 Hyperspectral remote sensing is based on measuring the scattered and reflected electromagnetic signals from the Earth’s surface emitted by the Sun. The received radiance at the sensor is usually degraded by atmospheric effects and instrumental (sensor ...
