Frameworks for efficient and accurate data processing often rely on a suitable representation of measurements that capture phenomena of interest. Typically, such representations are high-dimensional ...

The exponential smoothing method is widely used in time series forecasting. However, the smooth parameter α in single exponential smoothing model and double exponential smoothing model is unchanged in ...

Robust variable selection procedures through penalized regression have been gaining increased attention in the literature. They can be used to perform variable selection and are expected to yield ...

In the paper, we establish and study Hardy spaces with variable exponents on spaces of homogeneous type (X, d, μ) in the sense of Coifman and Weiss, where d may have no any regularity property and μ ...
