Diffeomorphic Transformations for Time Series Analysis: An Efficient Approach to Nonlinear Warping

no code implementations25 Sep 2023 Iñigo Martinez

Elastic metrics such as dynamic time warping (DTW) offer a promising approach, but are limited by their computational complexity, non-differentiability and sensitivity to noise and outliers.

Data Science Methodologies: Current Challenges and Future Approaches

no code implementations14 Jun 2021 Iñigo Martinez, Elisabeth Viles, Igor G. Olaizola

Few methodologies have been proposed on the literature that tackle these type of challenges, some of them date back to the mid-1990, and consequently they are not updated to the current paradigm and the latest developments in big data and machine learning technologies.
