Slowness principle
WebbThe seismic ray at any given point follows the direction of the gradient of the traveltime field . As before, let u be the unit vector along the ray. The ray in general will follow a curved path, and the raypath vector will be tangent to this curved raypath. Let us derive the ray equation. This equation tells us how the raypath vector changes ...

We show here that it is possible for SFA to detect... Webb22 feb. 2024 · It is quite well-understood now that deeper layers in an artificial neural network extract more and more abstract features, so, if we agree with the slowness principle, then it means that the deeper layers can work at a slower pace than the layers that are the input of the network.
WebbDownloadable! Following earlier studies which showed that a sparse coding principle may explain the receptive field properties of complex cells in primary visual cortex, it has been concluded that the same properties may be equally derived from a slowness principle. In contrast to this claim, we here show that slowness and sparsity drive the … WebbIn this thesis, we investigate slowness as an unsupervised learning principle of sensory …

The arrival of this pulse is detected at an array of receivers a few feet from the transmitter. The difference in time elapsed between the arrival of sound at the receivers is the desired travel time, the sound wave travels through the formation while ...
