CharacterTrajectories {mlmts}

CharacterTrajectories

Description

Multivariate time series (MTS) of character samples, captured using a WACOM tablet. Data was recorded at 200Hz.

Usage

data(CharacterTrajectories)

Format

A list with two elements, which are:

data

A list with 80 MTS.

classes

A numeric vector indicating the corresponding classes associated with the elements in data.

Details

Each element in data is a matrix formed by 182 rows (time points) indicating velocity trajectory and 3 columns (variables) indicating spatial dimension. The first 1422 elements correspond to the training set, whereas the last 1436 elements correspond to the test set. The numeric vector classes is formed by integers from 1 to 20, indicating that there are 20 different classes in the database. Each class is associated with a different alphabetical character. For more information, see Bagnall et al. (2018). Run "install.packages("ueadata1", repos="https://anloor7.github.io/drat")" to access this dataset and use the syntax "ueadata1::CharacterTrajectories".
