Robust Tree-based Causal Inference for Complex Ad Effectiveness Analysis

Pengyuan Wang, Wei Sun, Dawei Yin, Jian Yang, Yi Chang
2015 Proceedings of the Eighth ACM International Conference on Web Search and Data Mining - WSDM '15  
Our new framework enables analysis on uni-or multi-dimensional ad treatments, where each dimension (ad treatment factor) could be discrete or continuous.  ...  Moreover, to be practical in the data-rich online environment, the measurement needs to be highly general and efficient, which is not addressed in conventional causal inference approaches.  ...  Causal inference aims to infer unbiased causality effect of the ad treatment from observational data on chosen outcome metric, e.g., the effect of ads on success rates, by eliminating the impact of the  ...

Data Inference from Encrypted Databases: A Multi-dimensional Order-Preserving Matching Approach [article]

Yanjun Pan, Alon Efrat, Ming Li, Boyang Wang, Hanyu Quan, Joseph Mitchell, Jie Gao, Esther Arkin
2020 arXiv   pre-print
In this paper, for the first time, we study data inference attacks on multi-dimensional encrypted databases (with 2-D as a special case).  ...  So far, the effectiveness of such attacks is limited to single-dimensional dense data (most values from the domain are encrypted), but it remains challenging to achieve it on high-dimensional datasets  ...  [16] proposed an inference attack against property-preserving encryption on multi-dimensional data. This attack operates column by column.  ...
