The Real-Time ML Conundrum: Why It’s So Challenging (and How TurboML Solves It)

Before we jump into the steps, it’s crucial to appreciate why a TurboML real-time ML system is such a game-changer. Traditional batch processing for ML models, where data is collected and processed periodically (e.g., hourly, daily), simply isn’t sufficient for use cases demanding immediate responses. Fraud detection, for instance, requires evaluating transactions as they occur to prevent financial losses.

However, achieving real-time performance introduces significant engineering complexities:

1. Distributed Messaging Systems: Moving data asynchronously and reliably between services in real-time requires robust message buses like Apache Kafka or Redpanda. Setting up, scaling, and managing these systems is a specialized skill.
2. Real-Time Data Processing Engines: Beyond just moving data, you need to transform it on the fly. This means integrating and managing complex stream processing frameworks like Apache Flink or Apache Spark Streaming. Building custom connectors and ensuring low-latency transformations can be incredibly difficult.
3. Stateful Computations: Many real-time features, such as calculating “total amount spent in the last 24 hours,” require maintaining state over time. Implementing these “window features” at scale is notorious for its complexity.
4. Online Retraining and Model Versioning: In dynamic environments like fraud detection, fraud patterns constantly evolve. Your ML models need to continuously adapt through incremental updates (online retraining) without manual intervention. Furthermore, you need robust model versioning and rollback capabilities to ensure stability and diagnose issues.
5. Monitoring and Comparison: Once deployed, models need continuous monitoring. The ability to A/B test new models against production models in parallel, compare their performance metrics, and safely promote superior versions is vital for continuous improvement.

These challenges often lead to lengthy development cycles, high operational overhead, and a steep learning curve for teams trying to implement real-time ML. This is precisely where the TurboML real-time ML system shines. It abstracts away these infrastructural complexities, allowing you to define your ML logic in Python and deploy it with minimal effort, letting TurboML handle the heavy lifting.

Your 7-Step Journey to Building a Real-Time ML System with TurboML

Ready to experience the simplicity and power of TurboML real-time ML system for yourself? Follow thesAdd Poste steps to build your own real-time fraud detection pipeline.

Step 1: Set Up Your Development Environment and Clone the Project

The first step is to get the necessary code and development tools in place. The beauty of this setup is the use of “dev containers,” which ensure a consistent and isolated development environment, regardless of your local operating system.

1. Prerequisites:
   • Ensure you have Docker installed and running on your machine.
   • Install Visual Studio Code, as it offers excellent support for dev containers.
2. Clone the Repository:
   Open your terminal or command prompt and execute the following commands to get the project code:

   git clone https://github.com/Paulescu/end-to-end-real-time-ml
   cd end-to-end-real-time-ml
   

3. Open in VS Code and Reopen in Container:
   Once you’re in the project directory, open it with VS Code:

   code .
   

   If you don’t have the “Dev Containers” extension for VS Code installed, VS Code might prompt you to install it. After installation (or if already installed), you’ll see an option in the lower-left corner of VS Code (a green button) to “Reopen in Container.” Click this. VS Code will then build (if not already cached) and connect to the Docker-based development container. This container comes pre-configured with all the Python libraries and tools needed for interacting with the TurboML real-time ML system.

   • Pro Tip: To verify you’re inside the container, open a new terminal in VS Code (Terminal > New Terminal) and type uname. You should see output indicating a Linux environment, even if you’re on Windows or macOS. This confirms you’re in the isolated dev container.

Step 2: Authenticate Your TurboML Real-Time ML System Connection

To interact with the TurboML real-time ML system, you’ll need an account and your unique API credentials.

1. Sign Up for TurboML:
   Head over to https://turboml.com. Click on “Try Now” and sign up for a free account. TurboML offers a generous 24-hour free access period, which you can renew by simply signing up again, allowing ample time for experimentation and learning.
2. Obtain API Credentials:
   Once logged into your TurboML dashboard, navigate to the appropriate section (often “Settings” or “API Keys”) to find your Backend URL and API Key. These are crucial for programmatic access to the TurboML real-time ML system. Remember, your API key is a secret—do not share it publicly or commit it to your version control.
3. Configure Your Environment Variables:
   In your VS Code project, you’ll find a file named .env.example. Make a copy of this file and rename it to .env. Open the new .env file and paste your BACKEND_URL and API_KEY into the respective fields, replacing the placeholders. This file will be automatically loaded by your Python scripts for secure authentication.

Step 3: Define Your Feature Pipeline for the TurboML Real-Time ML System

Feature engineering is the art of transforming raw data into meaningful features that your ML model can learn from. In a real-time context, this needs to happen instantly as new data arrives. The TurboML real-time ML system simplifies this immensely through a declarative approach.

1. Understanding the Feature Pipeline:
   The project’s Makefile contains a command make feature-pipeline. This command executes a Python script that defines the feature engineering logic. Instead of manually setting up Kafka topics and Flink jobs, you simply describe what transformations you want, and the TurboML real-time ML system handles all the underlying infrastructure.
   For our fraud detection example, a crucial real-time feature is a “window feature” that calculates the total amount spent with a specific card in the last 24 hours. This type of stateful computation is typically hard to implement at scale, but TurboML makes it effortless.
2. Run the Feature Pipeline Command:
   In your VS Code terminal (connected to the dev container), execute:

   make feature-pipeline
   

   This script will communicate with the TurboML platform, registering your defined features.

3. Verify in TurboML Dashboard:
   Log back into your TurboML dashboard. Navigate to the “Features” section. You should now see new feature groups, including one for labels (0 for non-fraudulent, 1 for fraudulent) and another for features, which includes raw transaction data alongside your newly engineered “total amount spent” feature. This confirms your feature pipeline is active within the TurboML real-time ML system.

Step 4: Set Up and Deploy Your Predictive Model with TurboML

With your features defined, the next step is to create and deploy your predictive model. The TurboML real-time ML system streamlines this process, particularly focusing on the crucial aspects of online retraining and model versioning.

1. Model Definition:
   The make model command in the Makefile runs a Python script that defines how your model should work. You specify:
   • Input Features: Which features your model should use.
   • Labels: What the model should predict.
   • Model Type: For real-time applications, online ML algorithms like the Hoffding Tree Classifier (used in this example, from the River library) are ideal because they can learn incrementally from new data.
   • Feature Types: Differentiating between numerical and categorical features for proper encoding.
2. Online Retraining & Versioning:
   Fraud patterns are constantly evolving. A static model quickly becomes obsolete. The TurboML real-time ML system automates online retraining, ensuring your model continuously adapts to new patterns as data arrives. Furthermore, it implements robust model versioning, allowing you to track changes, compare performance between versions, and even roll back to a previous version if issues arise. This is an immense operational benefit for any production-grade real-time ML system.
3. Deploy Your Model:
   In your terminal, run the command:

   make model
   

   This submits your model definition to TurboML. The platform will then train an initial version of your model using any historical data already pushed and deploy it. If you’ve run this before with the same name, you might encounter an error due to name conflict. You can either delete the old model from the TurboML dashboard or modify the model’s name in the Python script to resolve this.

4. Verify Model Status:
   Return to your TurboML dashboard and navigate to the “Models” section. You should see your newly deployed model with a “Running” status. Under its details, you’ll also find information about model versions.

Step 5: Generate Live Data to Test Your TurboML Real-Time ML System

A real-time ML system thrives on a continuous stream of data. While in a production environment you’d connect to live data sources (e.g., a Kafka topic from your transaction system), for testing and integration, we’ll simulate this.

1. Simulating Production Data:
   The project includes a script that resamples historical transaction data and pushes it into the TurboML real-time ML system to mimic live data ingestion. This is a common and effective way to perform integration testing and ensure your entire pipeline, from feature engineering to model scoring, is functioning correctly.
2. Initiate Live Data Generation:
   In your terminal, execute the command:

   make live-data
   

   You’ll see output indicating transactions being pushed. This is designed to be a long-running process, continuously feeding data to your TurboML instance. You can let it run for a few minutes to generate sufficient data.

3. Monitor Model Predictions:
   Go back to your TurboML dashboard. Navigate to your model’s “Outputs” section. As data flows in from your make live-data script, you should observe the model actively scoring data and generating predictions. This confirms that your TurboML real-time ML system is operational and performing inferences in real time.
4. Stop Data Generation:
   Once you’ve seen sufficient data being scored, you can stop the make live-data process by pressing Ctrl+C in the terminal where it’s running.

Step 6: Master Model Monitoring and Comparison with TurboML

Deployment is just the beginning. In a production setting, continuous monitoring and the ability to compare models are paramount for maintaining high performance and iterating safely. The TurboML real-time ML system offers robust capabilities in this area.

1. Real-time Model Monitoring:
   Within your TurboML dashboard, under your model’s details, you’ll find metrics sections. Here, you can observe performance indicators (e.g., error rates, accuracy) of your deployed model in real time. This allows you to quickly identify any degradation in performance, which might signal new fraud patterns or data shifts.
2. A/B Testing with Model Comparison:
   A unique advantage of the TurboML real-time ML system is its seamless support for model comparison. If you develop a new version of your model (e.g., with new features or a different algorithm), you can deploy it in parallel with your existing production model. Both models will score incoming data, allowing you to compare their predictions and performance metrics side-by-side in the dashboard. This “champion-challenger” approach enables safe experimentation and ensures you only promote a new model to production once you’re confident it outperforms the current one.
   This feature is invaluable for continuously improving your real-time ML capabilities without risking your live application.
