Original data used in the Salient Subsequences demo

Source: R/mp-meat-data.R

This is the Meat dataset from UCR Archive modified for Salient discovery. The original data is mixed with Random Walks and the algorithm must pick only the originals.

mp_meat_data

Format

original is the original dataset with 60+60 observations mixed with 120 random walks:

data

240 time series with length of 448 each.

labels

label of each time series, -666 means a random walk.

sub_len

size of sliding window.

sub is the original dataset embedded in random walks:

data

One time series with length of 107520.

labels

label of each original data.

labels_idx

starting point where the original data was placed.

sub_len

size of sliding window.
