Overview
In today’s data-driven landscape, understanding and reacting to customer behavior in real time is a competitive advantage. This article explores how Transformer architecture can be applied within the Tealium Customer Data Platform (CDP) to generate richer, more actionable event data.
By combining AI-powered sequence modeling with Tealium’s real-time data capabilities, businesses can unlock advanced personalization, automated decision-making, and operational efficiency.
This article will help you:
- Understand what makes transformers unique for customer event data.
- Learn how transformers improve the quality and usability of event data.
- Discover industry-specific use cases enabled by this approach.
The Power of Transformer Architecture for Event Data
Traditional models designed for sequential data often process events one step at a time, limiting their ability to capture patterns across long event sequences. In contrast, transformers analyze entire sequences holistically through mechanisms like self-attention and positional encoding, unlocking richer and more actionable event insights.
Transformer Features that Improve Event Data
| Feature | What it does | Why it helps event data |
|---|---|---|
| Attention Mechanism | Learns relationships between events across a customer’s event history | Enables the model to determine which past events are most relevant when processing the current event (e.g., an abandoned cart from 3 sessions ago influencing today’s purchase) |
| Positional Encoding | Retains event order without relying on recurrence | Enables the model to recognize the correct order of events (e.g., distinguishing between product view → add to cart vs. add to cart → product view), which is essential for understanding customer behavior. |
| Parallelization | Processes all events in parallel during training and serves event-level inference at runtime | Enables scalable, real-time, and event-level inference when deployed within cloud environments. |
| Scalability | Handles millions of users and events simultaneously | Powers predictive models at enterprise scale by processing high-volume event streams outside Tealium infrastructure. |
The result
Tealium customers can generate more intelligent, more contextual, and actionable event data — ready for downstream activation in AudienceStream or other destinations.
Examples
Retail: A retailer uses transformers to detect that a shopper who viewed high-margin items last week is now browsing lower-value products. This context triggers a timely promotion in AudienceStream — increasing the chances of retaining their high-value behavior.
Travel: A travel site uses transformers to detect that a user who previously searched for business flights is now browsing weekend getaways. AudienceStream uses this shift in behavior to trigger personalized recommendations for premium leisure packages — improving cross-sell opportunities.
Finance: A financial institution identifies a user who recently explored mortgage calculators and is now spending time on credit score pages. This signals early-stage intent, allowing AudienceStream to deliver targeted educational content and nurture the lead through the funnel.
Healthcare: A healthcare provider sees a user navigating from general wellness articles to treatment-specific pages across sessions. The model recognizes this shift and routes the user to a relevant care program, driving timely engagement through downstream activation channels.
Visualizing the Architecture
The following diagram illustrates how transformer models integrate with Tealium’s Customer Data Hub to enable event-level enrichment and real-time activation. Events are collected, preprocessed, enriched externally, and then activated seamlessly within AudienceStream.

Events are ingested via EventStream, transformed via Functions, enriched externally through cloud-hosted Transformer Models, and activated in AudienceStream for real-time segmentation and personalized engagement.
From Features To Use Cases
The connection between the model’s features and business outcomes becomes clear when you consider how transformers can enrich event data:
- Rather than relying solely on simple event counts or last-click attribution, transformers process each incoming event while contextualizing it with the customer’s historical behavior.
Example: A customer may have browsed products, added them to their cart, and abandoned the purchase across multiple sessions. The transformer recognizes this pattern when the customer resumes browsing, enabling timely actions such as triggering a personalized abandonment email via AudienceStream. - Relationships between events are discovered automatically, surfacing hidden signals like cross-session purchase intent.
Example: The model may learn that customers who repeatedly view premium products without purchasing are highly likely to convert when offered a targeted discount, enabling predictive activation. - Predictions such as churn risk, next-best-action, or dynamic audience classification are generated in real-time from these enriched event streams and can be immediately leveraged within Tealium AudienceStream for customer engagement.
Example: The model may identify that a high-value user is likely to churn based on a recent drop in engagement compared to their historical behavior. AudienceStream can immediately trigger a personalized win-back offer to retain the user.
Common Scenarios Where Transformers Unlock Value
Event-level Capabilities:
- Real-time Event Enrichment: Enhance raw events before they enter the CDP.
- Predictive Analytics: Forecast key outcomes like churn, conversion, or high-value segments.
- Dynamic Audience Segmentation: Classify users based on full interaction history, not just latest behavior.
