The Randomized Causation Coefficient
نویسندگان
چکیده
We are interested in learning causal relationships between pairs of random variables, purely from observational data. To effectively address this task, the state-of-the-art relies on strong assumptions on the mechanisms mapping causes to effects, such as invertibility or the existence of additive noise, which only hold in limited situations. On the contrary, this short paper proposes to learn how to perform causal inference directly from data, without the need of feature engineering. In particular, we pose causality as a kernel mean embedding classification problem, where inputs are samples from arbitrary probability distributions on pairs of random variables, and labels are types of causal relationships. We validate the performance of our method on synthetic and real-world data against the state-of-the-art. Moreover, we submitted our algorithm to the ChaLearn’s “Fast Causation Coefficient Challenge” competition, with which we won the fastest code prize and ranked third in the overall leaderboard.

A causation coefficient and taxonomy of correlation/causation relationships
This paper introduces a causation coefficient which is defined in terms of probabilistic causal models. This coefficient is suggested as the natural causal analogue of the Pearson correlation coefficient and permits comparing causation and correlation to each other in a simple, yet rigorous manner. Together, these coefficients provide a natural way to classify the possible correlation/causation...

In this article, we will evaluate the concept of causation in medicine from a philosophical point of view and through histor...
متن کاملFactors of occupational injury: a survey in a chemical company.
Chemical industries being the seat of dangerous occurrences frequently resulting in injuries, an occupational injury surveillance study was initiated involving 307 permanent and 419 temporary workers in a chemical company to understand the contribution of different possible factors on injury causation. Risk calculation was undertaken in relation to every individual factor using univariate and m...
متن کاملThinking as Evidence for the Probability of the Existence of a God: An Argument from Unnaturalness for Necessity
The objective of this article is to show that it is justified to assert that the existence of God is plausible, considering the fact that thinking itself is an immediate outcome (effect) of a thinker (cause). This idea may seem evident, but it is in fact challenged by certain claims of cognitive philosophers who aver that our knowledge of necessity and causation is, i...
