The success of reinforcement learning in robotic tasks is highly dependent on the state representation – a mapping from high dimensional sensory observations of the robot to states that can be used for reinforcement learning. Even though many methods have been proposed to learn state representations, it remains an important open problem. Identifying the characteristics existing methods are opti...

Among the bovine diseases, mastitis causes high economic losses in dairy production system. Nowadays, detection under field conditions is mainly performed by California Mastitis Test, which considered de facto standard. However, this method presents with problems of slowness and expensiveness chemical-reactive process, deeply dependent on an expert’s trained eye and, consequently, highly imprec...

I apply array processing techniques to study the slowness and coda of P/Pdiff for 1,371 shallow earthquakes (< 200 km) that occurred in Asia, South America, Tonga-Fiji, and Indonesia, and were recorded by the medium-aperture array, YKA, in Canada. The slowness analysis shows lateral variations in Earth structure at the base of the mantle across the north Pacific. I observe an Ultra-Low Velocity...

In acoustic seismic-reeection experiments, because of the lack of low frequencies in the usual seismic sources, the reeection of the energy back to the surface is associated to the short wavelengths of the slowness (the reeectivityy parameters), while the long wavelengths of the slowness (the propagatorr parameters) are associated to the kinematics of the arrival times of this energy. Such a de...
