GECCO Challenge 2018 – Water Quality Time Series

Benchmark time series for water quality monitoring composed of multiple sensors and an associated binary event label. This dataset supports research in anomaly and event detection for environmental data streams. See cefet-rj-dal/united for usage guidance and links to the preprocessing steps used to build the package-ready object. Labels available: Yes.

Examples

data(gecco)
# Select the first univariate series and inspect
series <- gecco[[1]]
summary(series$value)
#>    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
#>   6.500   6.500   6.500   6.523   6.500   6.600 
# Plot values with event markers
plot(ts(series$value), main = names(gecco)[1], ylab = "value")
