EigenWorms_1
Description
Multivariate time series (MTS) indicating the movement of the worm Caenorhabditis elegans. The motion of worms in an agar plate is recorded as a combination of six base shapes.
Usage
data(EigenWorms_1)
Format
A list
with two elements, which are:
data
A list with 130 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 17984 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 first 130 elements
of the whole dataset are stored here. All these elements but the last two pertain to the training 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).
To access this dataset, run "install.packages("ueadata5", repos="https://anloor7.github.io/drat")"
and use the syntax "ueadata5::EigenWorms_1".
