It is now recognized that long memory and structural change can be confused because the statistical properties of times series of lengths typical of many financial and economic series are similar for both models. We propose a new test aimed at distinguishing between unifractal long memory and structural change. The approach, which utilizes the computationally efficient methods based upon Atheor...

Syst. 2022, 4, 2100093 In the originally published article, defining of weighting formula in equations (1) and (2) segment similarity (SWS) equation (3) had been presented incorrectly.

Image data can provide rich content information, which has attracted a lot of attention in the field indoor fingerprint positioning. However, image information from different locations is characterized by high repetition, and these repetitive regions cause problem insufficient differentiation adjacent fingerprints or even misclassification. To solve this problem, article proposes confusion subr...

In the present paper, the male of Spinisternum castaneipictus Willemse, previously unknown is described. The similarity of Spinisternum with other genera causes confusion in identification. This problem is discussed and similar species in different genera are compared. A key to species of Spinisternum and illustrations of S. castaneipictus are provided.

As human beings, our mental processes for recognising linguistic symbols generate perceptual neighbourhoods around such symbols where confusion errors occur. Such neighbourhoods also provide us with conscious mental associations between symbols. This paper formalises orthographic models for similarity of Japanese kanji, and provides a proofof-concept dictionary extension leveraging the mental a...

This work proposes a new segmentation evaluation metric, named boundary similarity (B), an inter-coder agreement coefficient adaptation, and a confusion-matrix for segmentation that are all based upon an adaptation of the boundary edit distance in Fournier and Inkpen (2012). Existing segmentation metrics such as Pk, WindowDiff, and Segmentation Similarity (S) are all able to award partial credi...

In this paper, we propose a method for text-query-based keyword spotting from online Chinese handwritten documents using character classi ̄cation model. The similarity between the query word and handwriting is obtained by combining the character classi ̄cation scores. The classi ̄er is trained by one-versus-all strategy so that it gives high similarity to the target class and low scores to the oth...
