SegmentSizeSuddenChange

Description

Sudden Change verses configure Mona to find timeseries-based anomalies, in which the latest point in a behavioral time-series data acts very differently than the rest of the time series. The latest point will be considered as an anomaly, if it is over (or under) a threshold. To calculate if the latest point is over/under this threshold we first measure the distance between the latest point value and some top (for over) or bottom (for under) percentile (a parameter). We then normalize this difference by the difference between the same top/bottom percentile and the median value of the timeseries.

'Segment Size Sudden Change' verses configure Mona to find segments, whose absolute size (the number of contexts in this segment) per time-frame has gone through a "sudden change" (as defined above) in the latest time frame compared to the rest of the segment sizes time series.

    "stanza_name": {
      "verses": [
        {
          "type": "SegmentSizeSuddenChange",
          "segment_baseline_by": [
            "company_id",

          "time_series_points": "60d"
        }
      ]
    }
  }
}

In this example we see a SegmentSizeSuddenChange verse which is configured to search for statistically significant changes in the size of any specific "detected_language" in the last day compared to the 59 days prior, within any different values of "country" and "company_id" as the baseline. Note that this verse type requires no "metrics" param. The "min_culprit_size" param will filter out countries or companies that on the day of the anomaly (the last day) have less then 50 records. We use "min_anomaly_level" to define that a sudden change occurs when the difference between the last day's average and the median of the entire time series is at least 3 times the difference between the 95 percentile of the entire time series and the median.

default_urgency	The urgency class for insights created using this verse. Currently, supports two values: "normal" (default) and "high". If set to "normal", then specific thresholds for "high" urgency can be set using other parameters prefixed with "highurgency". If set to "high", then threshold parameters prefixed with "highurgency" are not considered at all - since all insights of this verse will be considered as having a "high" urgency.	Urgency	normal

{ "default_urgency": "high" }

metrics

Name	Description	Type	Default
metrics	Relevant metrics to search anomalies for in the verse, relevant only for types who search for anomalies in metrics behavior.	MetricsList	()

{ "metrics": [ "top_score", "delta_top_to_second_score" ] }

min_anomaly_level

Name	Description	Type	Default
min_anomaly_level	This parameter sets the threshold for the minimal anomaly level for which an insight will be generated. Anomaly Level of this verse is the difference between the last point's value to the median value, normalized by the difference between the top_percentile_benchmark and the median.	PositiveFloat	2.5

{ "min_anomaly_level": 2 }

min_segment_size

Name	Description	Type	Default
min_segment_size	Minimal segment size to require for the entire time-series.	PositiveInt	5

{ "min_segment_size": 10 }

min_segment_size_fraction

Name	Description	Type	Default
min_segment_size_fraction	Minimal segment size in fraction from baseline segment, which a segment must have in order to be considered in the search.	InclusiveFraction	0

{ "min_segment_size_fraction": 0.05 }

name

Name	Description	Type	Default
name	(Required) The name of the verse. Please note, a verse's name must be different from other verses in the same stanza.	str	None

{ "name": "confidence_outliers" }

segment_by

Name	Description	Type	Default
segment_by	The dimensions to use to segment the data in order to search for anomalies. This list must be a sublist of all arc class' dimensions. Limiting the possible values of a specific segmentation field on which insights can be generated can be done using the "avoid_values" and the "include_only_values" keys in the segmentation JSON object, as seen in the example.	SegmentationsList	()

{ "segment_by": [ "city", "bot_id", {"name": "provider-code", "avoid_values": ["zoom"]}, {"name": "selected-language", "avoid_values": ["eng", "spa"]}, {"name": "country", "include_only_values": ["jpn"]} ] }

time_resolution

Name	Description	Type	Default
time_resolution	Time series time resolution period. Expected format is "" where can be any positive integer, and options currently include: "d" (days), or "w" (weeks). e.g, "1d" means 1 day period	TimeResolution	1d

{ "time_resolution": "1w"" }

time_series_points

Name	Description	Type	Default
time_series_points	Size of desired entire time series.	PositiveInt	60

{ "time_series_points": 30 }

trend_directions

Name	Description	Type	Default
trend_directions	A list of allowed anomalies trends directions - either 'asc' for ascending (anomalies in which the found value is LARGER THAN the relevant benchmark), or 'desc' for descending (anomalies in which the found value is SMALLER THAN the relevant benchmark).	TrendDirections	('asc', 'desc')

{ "trend_directions": [ "asc" ] }
