The future will also bring challenges in the real applications, both in picking applications that make sense from an economic point of view, and also in inventing whatever will be required to make them  ...  The inbetween case is lossy. So all real gases and materials are lossy!  ...  This is the compressibility term. You have adiabatic compressibility for wide open channels, isothermal compressibility for very tight channels, or something in-between for in-between channels.  ...

Artificial Intelligence [article]

Denis Rothman
2018 Zenodo  
In May 2017, Google revealed AutoML, an automated machine learning system that could create an artificial intelligence solution without the assistance of a human engineer.  ...  These cloud platforms will slowly but surely reduce the need for artificial intelligence developers. Google Cloud's AI provides intuitive machine learning services.  ...  They are lossy, which means that information is lost during the encoding-decoding phase, unlike standard lossless compression algorithms.  ...
