Leveraging Snowflake Cortex for Advanced AI and ML: New Functionalities for Analytics Teams
Table of Contents

The landscape of data analytics is rapidly evolving, with new tools and functionalities continuously being developed to enhance the capabilities of analytics teams. Snowflake Cortex has introduced several innovative machine learning (ML) and artificial intelligence (AI) features over the past couple of years, making it easier for teams to implement and scale their AI/ML workflows directly within the Snowflake environment. This blog post explores these new functionalities and how they can be leveraged for various use-cases.

1. Time Series Forecasting

Functionality: ML_FORECAST

Use-Case: Predicting future values based on historical time series data.

Example: Forecasting sales, stock levels, or demand for products.

Implementation:

SELECT
    date,
    sales,
    ML_FORECAST(
        sales,
        LOOKAHEAD=30
    ) OVER (ORDER BY date) AS forecasted_sales
FROM
    sales_data;

Benefits:

  • Provides accurate forecasts based on historical data trends.
  • Helps in planning and inventory management.

2. Anomaly Detection

Functionality: ML_DETECT_ANOMALIES

Use-Case: Identifying outliers or anomalies in datasets.

Example: Detecting fraudulent transactions or unusual behavior in network traffic.

Implementation:

SELECT
    transaction_id,
    amount,
    ML_DETECT_ANOMALIES(
        amount
    ) OVER () AS anomaly_score
FROM
    transactions;

Benefits:

  • Enhances security and fraud detection capabilities.
  • Automatically detects unusual patterns without extensive manual analysis.

3. Clustering

Functionality: ML_CLUSTER

Use-Case: Grouping similar data points into clusters.

Example: Segmenting customers based on purchasing behavior or demographics.

Implementation:

SELECT
    customer_id,
    ML_CLUSTER(
        age,
        annual_income,
        spending_score
    ) OVER () AS cluster_id
FROM
    customer_data;

Benefits:

  • Helps in market segmentation and targeting.
  • Identifies patterns and similarities within large datasets.

4. Linear Regression

Functionality: ML_REGRESS

Use-Case: Predicting a continuous outcome based on input features.

Example: Predicting house prices based on features like size, location, and number of bedrooms.

Implementation:

SELECT
    house_id,
    ML_REGRESS(
        price,
        size,
        location,
        bedrooms
    ) OVER () AS predicted_price
FROM
    housing_data;

Benefits:

  • Provides insights into relationships between variables.
  • Supports predictive modeling and trend analysis.

5. Classification

Functionality: ML_CLASSIFY

Use-Case: Classifying data points into predefined categories.

Example: Categorizing emails as spam or not spam, or predicting customer churn.

Implementation:

SELECT
    email_id,
    email_content,
    ML_CLASSIFY(
        email_content,
        model='pretrained-spam-model'
    ) OVER () AS classification
FROM
    email_data;

Benefits:

  • Automates the classification of large datasets.
  • Improves decision-making processes by categorizing data effectively.

6. Custom Model Inference

Functionality: ML_INFER

Use-Case: Running inference using custom pre-trained models.

Example: Using a custom-trained machine learning model to predict outcomes on new data.

Implementation:

SELECT
    data_point_id,
    feature1,
    feature2,
    ML_INFER(
        feature1,
        feature2,
        model='custom-model'
    ) OVER () AS prediction
FROM
    new_data;

Benefits:

  • Flexibility to use custom models trained outside of Snowflake.
  • Seamlessly integrates custom ML workflows within the Snowflake ecosystem.

Conclusion

Snowflake Cortex continues to expand its suite of ML and AI functionalities, providing powerful tools that significantly enhance the capabilities of analytics teams. These new features enable sophisticated analysis, from time series forecasting and anomaly detection to clustering, regression, classification, and custom model inference. By leveraging these tools, teams can streamline their workflows, gain deeper insights from their data, and drive more informed decision-making processes.
