Efficiently Discovering Locally Exceptional Yet Globally Representative Subgroups

2017

Subgroup discovery is a local pattern mining technique to find interpretable descriptions of sub-populations that stand out on a given target variable. That is, these sub-populations are exceptional with regard to the global distribution. In …

Testing Conditional Independence on Discrete Data using Stochastic\n Complexity

2019 · arXiv (Cornell University)

Testing for conditional independence is a core aspect of constraint-based\ncausal discovery. Although commonly used tests are perfect in theory, they\noften fail to reject independence in practice, especially when conditioning on\nmultiple variables.\n We focus on discrete …

Towards Plausible Graph Anonymization

2017 · SERVAL (Université de Lausanne)

Social graphs derived from online social interactions contain a wealth of information that is nowadays extensively used by both industry and academia. However, as social graphs contain sensitive information, they need to be properly anonymized …

Discovering Invariant and Changing Mechanisms from Data

2022 · Proceedings of the 28th ACM SIGKDD Conference on Knowledge Discovery and Data Mining

While invariance of causal mechanisms has inspired recent work in both robust machine learning and causal inference, causal mechanisms may also vary over domains due to, for example, population-specific differences, the context of data collection, …
