Handwriting
Description
Multivariate time series (MTS) indicating writing from a subject wearing a smartwatch.
Usage
data(Handwriting)
Format
A list
with two elements, which are:
data
A list with 1000 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 152 rows (time points) indicating acceleration trajectory and 3 columns (variables) indicating accelerometer value. The first 150 elements
correspond to the training set, whereas the last 850 elements correspond to the test set. The numeric vector classes
is formed
by integers from 1 to 26, indicating that there are 26 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::Handwriting".
