Non stretching NMO (Normal-Moveout) correction with DTW (Dynamic Time Warping) algorithm, study case: shallow target seismic

Journal of Physics: Conference Series, 2021
Abstract Normal Move Out (NMO) Correction using Common Mid-Point (CMP) data based on shallow target seismic. It has several problems for NMO correction. This constraint is caused by changes in extreme velocity gradients, resulting in less optimum value shallow target Common Mid-Point (CMP).

Development and application of a modified dynamic time warping algorithm (DTW-S) to analyses of primate brain expression time series [PDF]

BMC Bioinformatics, 2011
Comparing biological time series data across different conditions, or different specimens, is a common but still challenging task. Algorithms aligning two time series represent a valuable tool for such comparisons. While many powerful computation tools for time series alignment have been developed, they do not provide significance estimates for time ...

Combined Effects of Fat‐Tail and Spread Forecasting on Pairs Trading: A Hybrid Model Based on Integrating VAR With GRU Models

Journal of Forecasting, Volume 45, Issue 3, Page 1110-1128, April 2026.
ABSTRACT Pairs trading, a popular algorithmic trading strategy, exploits the short‐term price difference (spread) between two comoving assets. Empirically, the spread distribution of most assets in pairs trading has a fat‐tail characteristic that does not follow a normal distribution.
