Invariant Time-Series Classification [PDF]

open access: yes, 2012
Time-series classification is a field of machine learning that has attracted considerable focus during the recent decades. The large number of time-series application areas ranges from medical diagnosis up to financial econometrics. Support Vector Machines (SVMs) are reported to perform non-optimally in the domain of time series, because they suffer ...

A shapelet transform for time series classification [PDF]

open access: yesProceedings of the 18th ACM SIGKDD international conference on Knowledge discovery and data mining, 2012
The problem of time series classification (TSC), where we consider any real-valued ordered data a time series, presents a specific machine learning challenge as the ordering of variables is often crucial in finding the best discriminating features. One of the most promising recent approaches is to find shapelets within a data set.

Time Series Classification Based on Multi-Dimensional Feature Fusion

open access: yesIEEE Access, 2023
Time series classification is a key problem in data mining, most of existing classification methods directly extract one-dimensional data from one-dimensional features, which cannot effectively express the inter-relation between different time points ...

Discriminative Dictionary Learning for Time Series Classification

open access: yesIEEE Access, 2020
Time series symbolization based on the Symbolic Fourier Approximation (SFA) and a sliding window mechanism can effectively improve classification performance. Hence, it has become a research hotspot of time series representation learning.

Transfer learning for time series classification [PDF]

open access: yes2018 IEEE International Conference on Big Data (Big Data), 2018
Transfer learning for deep neural networks is the process of first training a base network on a source dataset, and then transferring the learned features (the network's weights) to a second network to be trained on a target dataset. This idea has been shown to improve deep neural network's generalization capabilities in many computer vision tasks such
