Описание: The legendary SR-71 Blackbird spy plane was, and still is, the world's only operational Mach 3 aircraft, and was designed, built, and tested by Lockheed's famed "Skunk Works." This new book covers all fifty Blackbirds built, from the first flight in 1962, to the last in 1999. As a replacement for the venerable U-2 spyplane, Lockheed went from contract signing to first flight in only thirty-two months starting in April 1958--from the beginning of design studies to the signing of a contract from the CIA to build the initial batch of A-12s in February 1960, to first flight in 1962. From the A-1 design through the completion of the very first Radar Cross Section models of the A-12, to the testing of every major system and subsystem, this book describes and illustrates the SR-71 as never before, using images from a variety of sources, as well as the author's own superb, new photography.
I hardly have to tell you that machine learning has become one of the most exciting technologies of today. Large companies such as Google, Facebook, Apple, Amazon, IBM, and many others are investing heavily in research into machine learning and its use for good reason. Even if you sometimes get the impression that "machine learning" is used as an empty catchphrase, it is undoubtedly not a fad. This exciting field opens up many new opportunities and is an integral part of everyday life. Think of the virtual assistants of smartphones, product recommendations for customers in online shops, the prevention of credit card fraud, spam filters in e-mail programs, the detection and diagnosis of disease symptoms.
