Boon Logic Amber Analytics Insight

Overview

Boon Logic's Amber™ platform is the first scalable, autonomously configuring, real-time unsupervised learning product for predictive maintenance and condition monitoring.

Amber™ is powered by the fastest unsupervised Machine Learning (ML) algorithm in the World, the Boon Nano, which quickly and autonomously learns the normal behavior of each individual Asset in your environment. Each Asset-specific model can identify anomalous activity with extreme precision and near 100% accuracy. Amber’s high-level insights allow your operators to know exactly when maintenance is needed, reducing downtime and preventative maintenance costs.

Leverage as an ExoSense™ Transform

The Amber Analytics Insight is an ExoSense™-compatible third-party Insight Module that implements patent-pending unsupervised machine learning methods capable of detecting anomalies from any individual or multi-sensor data stream in real-time.

Capability Highlights

  • Automatic tuning and training
  • Individual Asset-level models resulting in multiple analytic outputs
  • Early detection of anomolous behavior to inform predictive maintenance needs
  • Scalable and applicable to diverse kinds of signals
  • Removes reliance on limited human experience to set proper alarm thresholds

Outputs

The following table details the Signals and data generated by the Amber Analytics Insight.

Name Description Type Example Output
Amber Warning (AW)

Representation of Asset "health" based on a threshold of the AM metric auto-determined in Amber (see AM in "Metrics Expanded" section below)

0: Normal, 1: Asset Changing, 2: Asset Critical

The thresholds for the two warning levels are the standard statistical values of 0.95 (outlier) and 0.997 (extreme outlier) respectively

Possbile Values: 0, 1, 2

Number (int) 2
Metrics

Additional analytic metrics & metadata (see "Metrics Expanded" section below)

SI

With respect to the data seen before, values closer to 0 represent ordinary patterns and values closer to 1000 represent novel - potentially even anomalous - patterns

Number (int) 0 - 1000 382
AD

Anomaly Detection, a binary (boolean) result based on a threshold of the SI metric auto-determined in Amber

Number (int) 0 or 1 0
AH

Anomaly History, a rolling sum of Anomaly Detections over "recent history" (length based on {Samples to Buffer} - see "Configuration Parameters" section below)

Number (int) 0 - {Samples to Buffer} 7
AM

Amber Metric, indicates extent to which an unusually high number of anomlaies have occurred in recent history (based on AH)

The values are derived statistically from a Poisson model, with values closer to 0.0 and 1.0 respectively signaling a lower and higher frequency of anomalies than usual

Number (float) 0.0 - 1.0 0.31275
ID

Cluster ID, cluster into which the given input pattern is assigned

Number (int) 0 - {Max Clusters} 16

Tip

Custom Inline Insights can be used to split one or more of the above Metrics into their own dedicated Signal stream(s).

Configuration Parameters

The following table summarizes a list of configuration parameters for the Amber Analytics Insight.

Parameter Description Single Sensor Pre-Fused (Fusion) Example Value
Feature Count

Number of sensor data components included in each sample

Default: 1

Min: 1

Max: 1

Default: 1

Min: 1

8
Streaming Window Size

Indicates the number of successive samples to use in creating overlapping patterns

Example: With a Streaming Window Size of 50, each pattern clustered by the Insight is comprised of the most recent 50 samples, meaning each pattern overlaps the previous 49 samples with the latest 1

Default: 50

Min: 1

Max: 500

Default: 1

Min: 1

Max: 1

1
Samples to Buffer

Number of samples to be streamed before Autotuning begins on the buffered samples

Rolling window used for Anomaly History (AH) calculation

Note: This must be at least 10x {Streaming Window Size}, with a general rule of thumb being to consider 200-500x

Default: 10000

Min: 50

Default: 10000

Min: 50

43200
Learning Rate Numerator

Component of learning graduation requirement for stopping learning

See next

Default: 10

Min: 1

Default: 10

Min: 1

1
Learning Rate Denominator

Component of learning graduation requirement for stopping learning

The ratio {Learning Rate Numerator} / {Learning Rate Denominator} determines a cluster growth "flatness" threshold

During the most recent {Learning Rate Denominator} inferences, if there have been fewer than {Learning Rate Numerator} new clusters created, Learning will stop and Monitoring will begin

Default: 10000

Min: 1

Default: 10000

Min: 1

Learning Max Clusters

Learning graduation requirement for stopping learning

During the Learning phase, if the Insight reaches a total of {Learning Max Clusters} in its model, Learning will stop and Monitoring will begin

Default: 10000

Min: 1

1000
Learning Max Samples

Learning graduation requirement for stopping learning

During the Learning phase, if the Insight has processed a total of {Learning Max Samples}, Learning will stop and Monitoring will begin

Tips

  • The Samples to Buffer configuration approximately determines which samples are available for the Autotuning state, during which the generalized Min & Max values of any feature(s) will be identified.
    • The value to use may change based on the typical operating times and general behavior patterns of the target Asset.
    • If historical data is available, consider reviewing the data (e.g. on a Line Chart, Data Table, etc.) to see if there are any temporal (hourly, daily, weekly, etc.) patterns.
    • It is also often helpful to talk with someone who works directly with the Asset.
  • For a Single Sensor stream, given the relationship among sequential time series measurements of a single feature is evaluated, the Streaming Window Size must be greater than 1.
  • For a Pre-Fused (Fusion) stream, given the relationship among all features included in each sample is evaluated, a Streaming Window Size of 1 is generally sufficient.

Note

Once configuration parameters have been set for a given instance of the insight they cannot be changed. To analyze the stream with different parameters, create a new instance with the desired changes.

Setup Guide

  • You can now edit the properties of these Signals (e.g. to change the "precision" for the integer-type Amber Warning (AW)).
  • As noted earlier, you may also consider using Custom Inline Insights to split one or more of the Additional Metrics into their own dedicated Signal stream(s).
