A/B Testing in Networks with Adversarial Members
Author:
Kaleigh Clary, Department of Computer Science, University of Massachusetts Amherst
Abstract:
Many researchers attempt to study the effects of interventions in network systems. To simplify experimental design and analysis in these environments, simple assumptions are made about the behavior of its members. However, nodes may not respond to treatment, or may respond maliciously. These adversarial nodes influence treatment topology by preventing or altering the expected network effect, but may not be known or detectable. We characterize the influence of adversarial nodes and the bias these nodes introduce in average treatment effect estimates. In particular, we derive expressions for the bias induced in average treatment effect using the linear estimator from Gui et al (2015). In addition to theoretical bounds, we empirically demonstrate estimation bias through experiments on synthetically generated networks. We consider both the case in which adversarial nodes are dispersed randomly through the network and the case where adversarial node placement is targeted to the highest degree nodes. Our work demonstrates that peer influence makes causal estimates on networks susceptible to the actions of adversaries, and specific network structures are particularly vulnerable to to adversarial responses.

Blacklisting the Blacklist in Online Advertising

Author: Yeming Shi, Dstillery Abstract: Every day, billions of online advertising slots are bought and sold through real time bidding (RTB). In RTB, publishers sometimes reject bids to deliver ads (impressions) for some brands, due to, for example, direct deals with other brands. Publishers rarely disclose which brands they blacklist to ad buyers. Buyers bidding for a blacklisted brand waste co...

    Gemini 1.5 Pro: This video is about Google Vizier, a service for blackbox optimization developed by Google. Blackbox optimization is a type of optimization where the system you are trying to optimize is opaque, meaning you can only evaluate different configurations by running experiments. Vizier makes it easy to define and run these experiments, and it also provides a number of features to help you improve the efficiency of your search. Here are the key design goals of Vizier: * Ease of use: Vizier is designed to be easy to use, even for people who are not familiar with blackbox optimization. * Availability: Vizier is highly available, so you can be confident that it will be up and running when you need it. * Scalability: Vizier can scale to handle large workloads, so you can use it to optimize even the most complex systems. * Performance: Vizier uses state-of-the-art algorithms to find the best possible configuration for your system. * Flexibility: Vizier is flexible and can be used to optimize a wide variety of systems. Vizier is a powerful tool that can be used to optimize a wide variety of systems. It is easy to use, available, scalable, performs well, and flexible. If you are looking for a way to improve the performance of your system, Vizier is a great option to consider. Some of the applications of Vizier include: * Automated optimization for user interfaces or user experience * Optimizing machine learning models * Physical design problems * Robotics One interesting example of how Vizier has been used is to design chocolate chip cookies. By parameterizing the space of possible cookie recipes, Vizier was able to generate a series of cookies that were then taste-tested by humans. The results of this experiment were used to improve the Vizier algorithm.
