A Note on the Size of Denoising Neural Networks

چکیده

Patch based denoising algorithms seek to approximate the conditional expectation of clean patches given their related noisy observations. In this note, we give a probabilistic account of how various algorithms approach this problem and in particular, we argue that small neural networks can denoise small-scale texture patterns almost as well as their large counterparts. The analysis further indicates that self-similarity and Bayesian approaches such as neural networks are complementary paradigms for patch denoising, which we illustrate with an algorithm that effectively complements BM3D with small neural networks, thereby outperforming BM3D with minor additional cost.

Color Matching of Blends Prepared From Black and White Fibers by Neural Networks (TECHNICAL NOTE)

The color of the blends of pre-colored fibers depends on the ratio of each fiber in the blends. Some theories have been introduced for color matching of blends of pre-colored fibers. Most however, are restricted in scope and accuracy. Kubelka and Munk presented the most applicable theory, which is still used in industry. In this work, the classical Kubelka-Munk method for color prediction of a ...

Application of ANN Technique for Interconnected Power System Load Frequency Control (RESEARCH NOTE)

This paper describes an application of Artificial Neural Networks (ANN) to Load Frequency Control (LFC) of nonlinear power systems. Power systems, such as other industrial processes, have parametric uncertainties that for controller design had to take the uncertainties in to account. For this reason, in the design of LFC controller the idea of robust control theories are being used. To improve ...

Classification of ECG signals using Hermite functions and MLP neural networks

Classification of heart arrhythmia is an important step in developing devices for monitoring the health of individuals. This paper proposes a three module system for classification of electrocardiogram (ECG) beats. These modules are: denoising module, feature extraction module and a classification module. In the first module the stationary wavelet transform (SWF) is used for noise reduction of ...
