Notel (Korean: 노텔), also called NoteTel, is a brand of portable media player made in China which is popular in North Korea. The word is a portmanteau of "notebook" and "television". It is estimated that up to half of all urban North Korean households have a notel.[1][2] The device has USB and SD ports, can play DVDs and EVDs, and contains radio and television tuners. It can also be powered and rec
In sound processing, the mel-frequency cepstrum (MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients (MFCCs) are coefficients that collectively make up an MFC.[1] They are derived from a type of cepstral representation of the audio clip (a nonlinea
Free Speech flag, from the HD DVD AACS case An illegal number is a number that represents information which is illegal to possess, utter, propagate, or otherwise transmit in some legal jurisdiction. Any piece of digital information is representable as a number; consequently, if communicating a specific set of information is illegal in some way, then the number may be illegal as well.[1][2][3] Back
RDRAND (for "read random") is an instruction for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source.[1] It is also known as Intel Secure Key Technology,[2] codenamed Bull Mountain.[3] Intel introduced the feature around 2012, and AMD added support for the instruction in June 2015. (RDRAND is available in Ivy Bridge pro
A partially observable Markov decision process (POMDP) is a generalization of a Markov decision process (MDP). A POMDP models an agent decision process in which it is assumed that the system dynamics are determined by an MDP, but the agent cannot directly observe the underlying state. Instead, it must maintain a sensor model (the probability distribution of different observations given the underly
