Signal Pattern Recognition Based on Fractal Features and Machine Learning
Applied Sciences, 2018 As a typical pattern recognition method, communication signal modulation involves many complicated factors. Fractal theory can be used for signal modulation feature extraction and recognition because of its good ability to express complex information. In

Research on a Fractal Dimension Calculation Method for a Nano-Polymer Microspheres Dispersed System
Frontiers in Chemistry, 2021 Polymer microspheres (PMs) are a kind of self-similar volume expansion particle, and their fractal dimension varies with hydration swelling. However, there is no unique fractal dimension calculation method for their characteristics.

On the Beurling dimension of exponential frames [PDF]
, 2010 We study Fourier frames of exponentials on fractal measures associated with a class of affine iterated function systems. We prove that, under a mild technical condition, the Beurling dimension of a Fourier frame coincides with the Hausdorff dimension of ...

Stochastic models which separate fractal dimension and Hurst effect [PDF]
, 2001 Fractal behavior and long-range dependence have been observed in an astonishing number of physical systems. Either phenomenon has been modeled by self-similar random functions, thereby implying a linear relationship between fractal dimension, a measure ...

Martingale dimensions for fractals
The Annals of Probability, 2008 We prove that the martingale dimensions for canonical diffusion processes on a class of self-similar sets including nested fractals are always one. This provides an affirmative answer to the conjecture of S. Kusuoka [Publ. Res. Inst. Math. Sci. 25 (1989) 659--680].
