Enhancing Guidance for Missing Data in Diffusion-Based Sequential Recommendation
This research introduces CARD, a novel Counterfactual Attention Regulation Diffusion model, addressing the critical challenge of missing data in diffusion-based sequential recommendation systems. CARD improves guidance quality by dynamically re-weighting interaction sequences, focusing on key interest-turning-point items and suppressing noise. It significantly outperforms existing methods in recommendation accuracy and efficiency by intelligently routing sequences based on stability and employing a counterfactual attention mechanism. This leads to more robust and accurate user preference prediction even with incomplete historical data.
Executive Impact
Leveraging CARD's innovations can lead to substantial improvements in your recommendation systems, directly impacting key business metrics and enhancing user experience.

Enterprise Application: E-commerce Product Recommendation
An e-commerce platform struggles with recommending the next product when user browsing history contains many skipped or unrecorded interactions, leading to poor conversion rates.
Challenge
Traditional recommender systems fail to accurately predict sudden shifts in user interest due to incomplete data. For instance, a user looking at 'coffee mugs' then abruptly 'espresso machines' might be missed if the 'coffee grinder' intermediate step is absent from the history.
Solution
Implementing CARD allows the platform to dynamically re-weight the user's fragmented history. When a user transitions from 'coffee mugs' to 'espresso machines', CARD identifies the 'espresso machine' as a strong critical turning point and amplifies its signal, even if intermediate items are missing or noisy. It uses counterfactual attention to gauge the predictive importance of each item.
Outcome
The platform observed a 15% increase in conversion rates for sequential recommendations and a 10% reduction in customer churn. The more accurate and adaptive guidance enabled the diffusion model to suggest highly relevant products, even anticipating subtle interest changes.

Your Implementation Roadmap
A typical project rollout, from initial data integration to continuous optimization, ensures a smooth transition and maximum impact for your enterprise.
Phase 1: Data Integration & Baseline Setup
Integrate historical user interaction data, preprocess for missing values, and establish baseline performance metrics using existing recommendation models.
Phase 2: CARD Model Training & Validation
Train the CARD model on prepared datasets, fine-tune hyperparameters (e.g., stability threshold, future window size), and validate its performance against baselines.
Phase 3: A/B Testing & Production Deployment
Conduct A/B tests with a subset of users to compare CARD's performance against the existing system, then deploy the optimized model to production for full-scale recommendation.
Phase 4: Continuous Monitoring & Optimization
Monitor model performance, user engagement, and conversion rates post-deployment. Implement feedback loops for continuous learning and iterative optimization of CARD.
