Title: *Inferring causality in dynamical processes with the Information 
Imbalance of distance ranks*

Abstract:

Uncovering causal relationships between time-dependent observables is a 
problem which goes at the heart of scientific research. However, 
distinguishing a cause-effect relationship from a correlation, possibly 
induced by a quantity which is not observed, or unknown, is still 
considered an open problem, especially if the effect is triggered by the 
simultaneous variation of a large number of variables. Nowadays, the 
performance of many causal detection methods degrades quickly with the 
number of variables that one should consider. Moreover, in real-world 
contexts most of the approaches lead to false-positives, namely have 
difficulties in recognizing the absence of causality.

In this talk, I will illustrate a new method built on the Information 
Imbalance measure, which significantly mitigates these problems. In 
particular, the use of distance ranks instead of plain variables allows 
circumventing the problem of estimating probability densities, handling 
high-dimensional data that are challenging for other approaches.
