A theory of independent mechanisms for extrapolation in generative models

Generative models can be trained to emulate complex empirical data, but are they useful to make predictions in the context of previously unobserved environments? An intuitive idea to promote such **extrapolation** capabilities is to have the …

Groupe invariance principles for causal generative models

The postulate of independence of cause and mechanism (ICM) has recently led to several new causal discovery algorithms. The interpretation of independence and the way it is utilized, however, varies across these methods. Our aim in this paper is to …

Shifts of Gamma Phase Reflect Dynamic Information Transfer

We investigate how oscillations of cortical activity in the gamma frequency range (50–80 Hz) may influence dynamically the direction and strength of information flow across different groups of neurons. We found that the arrangement of the phase of gamma oscillations at different locations indicated the presence of waves propagating along the cortical tissue were observed to propagate along the direction with the maximal flow of information transmitted between neural populations. Our findings suggest that the propagation of gamma oscillations may reconfigure dynamically the directional flow of cortical information during sensory processing.
