Leveraging Alibaba Cloud Elasticsearch for Intelligent Data Detection and Prediction

This guide unveils how to seamlessly integrate anomaly detection and prediction into your data, enhancing your business's decision-making processes and operational efficiency.

Elasticsearch Machine Learning stands as a robust tool that allows for intelligent detection and prediction within data hosted on Elasticsearch, all owing to its sophisticated machine learning technology. From automatically identifying data patterns and anomalies to generating new features and aggregation results, Elasticsearch Machine Learning aims to boost data availability and value, thus providing more intelligent and efficient solutions for data analysis and utilization. Focusing on Alibaba Cloud Elasticsearch, this article walks you through implementing unsupervised and supervised machine learning tasks to enrich your business data insights.

Background Information

Alibaba Cloud Elasticsearch supports two primary learning modes: unsupervised and supervised machine learning.

Unsupervised Machine Learning detects anomalies in data without being trained on what constitutes an anomaly.
Supervised Machine Learning involves training a model on specific data to classify new data and make predictions based on regression and classification algorithms.

Preparations

Before diving into machine learning with Elasticsearch, ensure you have:

1）Created an Alibaba Cloud Elasticsearch cluster, preferably Elasticsearch V8.5 (Create an Alibaba Cloud Elasticsearch cluster).

2）Logged on to the Kibana console of your Elasticsearch cluster to add sample data for analysis.

// A snippet from the Sample web logs dataset
{
  "_index": "kibana_sample_data_logs",
  ...
  "geo": {
    "coordinates": {
      "lat": 31.24905556,
      "lon": -82.39530556
    }
  },
  ...
  "url": "https://www.elastic.co/solutions/logging",
  ...
}

Create a Machine Learning Task

Unsupervised Learning Task: Analyzing Web Logs

PUT _ml/anomaly_detectors/weblogs_single_metric
{
  "analysis_config": {
    "bucket_span": "15m",
    "detectors": [
      {
        "function": "count",
        "partition_field_name": "geo.src"
      }
    ]
  },
  ...
}

This example sets up an unsupervised machine learning task to analyze web server access behaviors, optimizing website performance and identifying anomalous access trends.

Supervised Learning Task: Flight Delay Prediction

Using the Sample flight data, we aim to predict flight delays based on historical data. Below is how you segment the data:

{
  "_index": "kibana_sample_data_flights",
  ...
  "OriginWeather": "Cloudy",
  "AvgTicketPrice": 824.8516378170061,
  ...
  "FlightDelay": false,
  ...
}

Creating an Inference Machine Learning Task:

1）Navigate to Analytics > Machine Learning in the Kibana console.

2）Choose Data Frame Analytics > Jobs and create a new job focusing on Regression.

PUT _ml/data_frame/analytics/flight_delay_prediction
{
  "source": {
    "index": "kibana_sample_data_flights"
  },
  "dest": {
    "index": "flight_delay_predictions"
  },
  "analysis": {
    "regression": {
      "dependent_variable": "FlightDelayMin"
    }
  },
  ...
}

3）After creating the job, evaluate its metrics in the Model evaluation section for reliability assessment.

Using the Flight Delay Prediction Task

To apply the model:

PUT _ingest/pipeline/flight_flightDelayMin_predict
{
  "processors": [
    {
      "inference": {
        "model_id": "flightDelayMin_job-168609891****",
        "inference_config": { "regression": {} },
        ...
      }
    }
  ]
}

This instructs Elasticsearch to predict flight delays based on new data entering the system.

POST _ingest/pipeline/flight_flightDelayMin_predict/_simulate
{
  ...
}

Performing this data analysis predicts the delay time for each flight, providing valuable insights for airlines and passengers alike.
