Context and question: The simplest type of MP3 file uses one bit rate for the entire file: this is known as Constant Bit Rate (CBR) encoding. Using a constant bit rate makes encoding simpler and faster. However, it is also possible to create files where the bit rate changes throughout the file. These are known as Variable Bit Rate (VBR) files. The idea behind this is that, in any piece of audio, some parts will be much easier to compress, such as silence or music containing only a few instruments, while others will be more difficult to compress. So, the overall quality of the file may be increased by using a lower bit rate for the less complex passages and a higher one for the more complex parts. With some encoders, it is possible to specify a given quality, and the encoder will vary the bit rate accordingly. Users who know a particular "quality setting" that is transparent to their ears can use this value when encoding all of their music, and generally speaking not need to worry about performing personal listening tests on each piece of music to determine the correct bit rate.
What does CBR stand for?
Answer: Constant Bit Rate
Context and question: In The Sensory Order: An Inquiry into the Foundations of Theoretical Psychology (1952), Hayek independently developed a "Hebbian learning" model of learning and memory an idea which he first conceived in 1920, prior to his study of economics. Hayek's expansion of the "Hebbian synapse" construction into a global brain theory has received continued attention in neuroscience, cognitive science, computer science, behavioural science, and evolutionary psychology, by scientists such as Gerald Edelman, and Joaquin Fuster.
In what year was the book published in which Hayek developed Hebbian learning?
Answer: 1952
Context and question: Roman histories and biographies anticipated the extensive mediaeval literature of lives of saints and miraculous chronicles, but the most characteristic form of the Middle Ages was the romance, an adventurous and sometimes magical narrative with strong popular appeal. Controversial, religious, political and instructional literature proliferated during the Renaissance as a result of the invention of printing, while the mediaeval romance developed into a more character-based and psychological form of narrative, the novel, of which early and important examples are the Chinese Monkey and the German Faust books.
Greek classic literature influenced what genre of literature?
