WebMay 27, 2024 · Smith-Waterman As part of a speech recognition project to extract usable training data from speech data with noisy reference transcriptions, I reimplemented the (striped) Smith-Waterman (SSW) that was used to create the LibriSpeech corpus. The Smith–Waterman algorithm has several steps: Determine the substitution matrix and the gap penalty scheme. A substitution matrix assigns each pair of bases or amino acids a score for match or mismatch. Usually matches get positive scores, whereas mismatches get relatively lower scores. See more The Smith–Waterman algorithm performs local sequence alignment; that is, for determining similar regions between two strings of nucleic acid sequences or protein sequences. Instead of looking at the entire sequence, the … See more In 1970, Saul B. Needleman and Christian D. Wunsch proposed a heuristic homology algorithm for sequence alignment, also referred to as the … See more Smith–Waterman algorithm aligns two sequences by matches/mismatches (also known as substitutions), insertions, and deletions. Both insertions and deletions are the operations that introduce gaps, which are represented by dashes.

WebThe striped Smith–Waterman implementation takes a similar approach by pre-calculating the query profile, but with a different layout than Rognes (Fig. 1). The layout used by the query profile is a striped access parallel to the query sequence. The query is divided into equal length segments, S. http://sc15.supercomputing.org/sites/all/themes/SC15images/tech_poster/poster_files/post269s2-file3.pdf http://cryptogenomicon.org/farrars-striped-simd-smith-waterman.html greystones sheffield gig guide
