Knowledge-informed Bidding with Dual-process Control for Online Advertising
This research introduces KBD, a novel two-stage bid optimization method for online advertising. It integrates human expertise through Informed Machine Learning, globally optimizes multi-step bidding sequences with Decision Transformers, and leverages dual-process control (PID and DT) for robust adaptation in dynamic environments. Experiments demonstrate KBD's superior performance and resilience to distribution shifts.
Executive Impact & Strategic Advantage
KBD offers significant advancements for enterprises in online advertising, addressing common limitations of black-box ML models to deliver more adaptable, efficient, and globally optimized bidding strategies.

Impact of Knowledge Integration (IML)
The Informed Machine Learning (IML) framework, particularly the IE module with its price-volume interpreter, is crucial for improving bid optimization. It ensures robust performance in data-sparse settings and allows for the integration of human expertise as inductive biases, leading to more reliable and interpretable models.
Dual-process Control for Robustness
The dual-process control mechanism, combining a fast rule-based PID controller (System 1) with a deliberative Decision Transformer (System 2), significantly enhances robustness against data distribution shifts. This hybrid approach allows for both reliable constraint adherence and optimal long-term reward maximization.
KBD Methodology Flow
KBD operates in a two-stage process: a macro (daily) stage for establishing a base tCPA using Informed Machine Learning, and a micro (hourly) stage for dynamic adjustments via dual-process control with Decision Transformer and PID controller.
IEFormer Robustness to Segment Number
The IEFormer model, a core component of the macro stage, demonstrates strong robustness to the choice of the number of segments (N) used in its price-volume interpreter. This indicates reliable performance regardless of specific configuration choices, maintaining high accuracy across various settings.

Case Study: Dual-process Control in Action
In real-world online advertising deployments, the KBD framework's dual-process control significantly improves key metrics, particularly during periods of market volatility such as sales promotions or new product launches. The PID controller (System 1) provides a robust, constraint-adherent baseline, preventing overly aggressive bids and ensuring budget compliance. Simultaneously, the Decision Transformer (System 2) refines these bids for long-term optimal returns, calibrating the PID's decisions with a global perspective. This hybrid approach leads to consistent gains in cost-exhaust ratio and GMV, demonstrating KBD's ability to adapt and maintain performance where traditional ML models fail due to distributional shifts.
