Unbiased Lift-based Bidding System [article]

Daisuke Moriwaki and Yuta Hayakawa and Isshu Munemasa and Yuta Saito and Akira Matsui
2020 arXiv   pre-print
In this study, we develop Unbiased Lift-based Bidding System, which maximizes the advertisers' profit by accurately predicting the lift-effect from biased log data.  ...  Our system is the first to enable high-performing lift-based bidding strategy by theoretically alleviating the inherent bias in the log.  ...  PROPOSED METHOD In this section, we propose and describe our Unbiased Lift-based Bidding System.  ...

A Decentralized Redeployment Algorithm for Improving the Availability of Distributed Systems [chapter]

Sam Malek, Marija Mikic-Rakic, Nenad Medvidovic
2005 Lecture Notes in Computer Science  
For these reasons, the existing techniques are not applicable to an emerging class of decentralized systems marked by the limited system wide knowledge and lack of centralized control.  ...  As a result of connectivity losses, the overall availability of the system decreases.  ...  For this reason, executing the exact algorithm is only feasible for very small systems.

Counterfactual-based Incrementality Measurement in a Digital Ad-Buying Platform [article]

Prasad Chalasani, Ari Buchalter, Jaynth Thiagarajan, Ezra Winston
2017 arXiv   pre-print
MediaMath (a DSP) has developed the first practical, statistically sound randomization-based methodology for causal ad effectiveness (or Ad Lift) measurement by a DSP (or similar digital advertising execution  ...  system that may not have full control over the advertising transaction mechanisms).  ...  In such cases, all cookie-based response rates would effectively be zero, as conversions cannot be associated with bid opportunities, and Ad Lift becomes indeterminate.  ...

Bid optimizing and inventory scoring in targeted online advertising

Claudia Perlich, Brian Dalessandro, Rod Hook, Ori Stitelman, Troy Raeder, Foster Provost
2012 Proceedings of the 18th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '12  
This paper presents a bid-optimization approach that is implemented in production at Media6Degrees for bidding on these advertising opportunities at an appropriate price.  ...  Billions of online display advertising spots are purchased on a daily basis through real time bidding exchanges (RTBs).  ...  So the reported lift is not the lift of our full targeting and bid optimization, but only the lift of inventory selection on top of the regular selection.  ...

The covered topics include user response prediction, bid landscape forecasting, bidding algorithms, revenue optimisation, statistical arbitrage, dynamic pricing, and ad fraud detection.  ...  The most significant progress in recent years in online display advertising is what is known as the Real-Time Bidding (RTB) mechanism to buy and sell ads.  ...  showed that although such a lift-based bidding strategy indeed brought more conversions to the advertiser, more conversions are assigned to the competitive value-based bidding strategies than the lift-based  ...
