WebSep 1, 2024 · Although DTW has been successfully used for many years, it still encounters some pairwise alignment challenges. In [24] the authorts reported unintuitive alignments when the algorithm tries to express amplitude variability in the Y-axis by improper warping the X-axis. This behaviour leads to situations defined as ”singularities”, where a single … WebAug 12, 2013 · The dynamic time warping seems suitable for adjustment of derived genomic signals. DTW originally serves for processing of digital signals sampled at defined time instances. In genomic signals, time instances are represented by indexes of nucleotides. The signals based on cumulated phase carry not only useful information, but also noise.
