Data augmentation for multivariate time series classification

or

How do you make a ghost jump?

Can time series classifiers benefit from synthetic data augmentation? In the notebooks in this repository, I explore the application of synthetic data augmentation using weighted dynamic time warping barycenter averaging to improving the performance of a 1-NN DTW-based classifer for multivariate time series.

Notebooks:

  1. summary.ipynb - An overview of the methodology and results
  2. syntheticdatageneration.ipynb - Synthetic data generation
  3. testandplotclassificationaccuracy.ipynb - Testing the classification accuracy as a function of the degree of data augmentation
  4. rawtimeseriesvisualization.ipynb - Plotting raw time series data
  5. 3DtSNEvisualizations.ipynb - Plotting a 3D t-distributed stochastic neighbor embedding of baseline and augmented datasets
