Threshold Anomaly Detection

No algorithm description given

Threshold Anomaly Detection This algorithm detects out of bounds data-points from a time-series dataset and sets them to 0. Table of Contents Introduction Inputs Outputs Algorithm Console Introduction By using the pre-defined upper & lower bounds, this algorithm will keep all data-points that lie within the thresholds. All data-points that lie outside are set to 0. Inputs This algorithm has two input formats; JSON Formatting and Array Formatting. JSON Format { 
 "data": Double[],
 "lowerBound": Double,
 "upperBound": Double
} { 
 "data": [1,2,3,4,3,4,6,7,5,4,2,1,1],
 "lowerBound": 1.4,
 "upperBound": 6.5
} data -   (required)   - The time series input data you wish to detect anomalies on, this algorithm assumes the values are evenly spaced. ( dx(1) == dx(n) ) lowerBound -   (optional)   - The lower boundary limit,  the default value is 0. upperBound -   (optional)   - The upper boundary limit,  the default value is 0. Array Format [
 data: Double[],
 lowerBound: Double,
 upperBound: Double
] [[1,2,3,4,3,4,6,7,5,4,2,1,1], 1.4, 6.5] data -   (required)   - The time-series input data you wish to detect anomalies on, this algorithm assumes the values are evenly spaced. ( dx(1) == dx(n) ) lowerBound -   (required)   - The lower boundary limit. upperBound -   (required)   - The upper boundary limit. Outputs This algorithm has json output for json input, and array output for array input. JSON Format { 
 "output": Double[]
} { 
 "output": [0,2,3,4,3,4,6,0,5,4,2,0,0]
} output - The filtered dataset, if a data-point was considered out of bounds it’s value is set to 0. Array Format output: Double[] [0,2,3,4,3,4,6,0,5,4,2,0,0] output - The filtered dataset, if a datapoint was considered out of bounds it’s value is set to 0.
