Skyline matrixIn scientific computing, skyline matrix storage, or SKS, or a variable band matrix storage, or envelope storage scheme is a form of a sparse matrix storage format matrix that reduces the storage requirement of a matrix more than banded storage. In banded storage, all entries within a fixed distance from the diagonal (called half-bandwidth) are stored. In column-oriented skyline storage, only the entries from the first nonzero entry to the last nonzero entry in each column are stored.
Symbol grounding problemThe symbol grounding problem is the problem of how "...symbol meaning..." is "...to be grounded in something other than just more meaningless symbols" [Harnad, S. (1990)]. This problem is of significant importance in the realms of philosophy, cognition, and language. In cognitive science and semantics, the symbol grounding problem is concerned with how it is that words (symbols in general) get their meanings, and hence is closely related to the problem of what meaning itself really is.
SonificationSonification is the use of non-speech audio to convey information or perceptualize data. Auditory perception has advantages in temporal, spatial, amplitude, and frequency resolution that open possibilities as an alternative or complement to visualization techniques. For example, the rate of clicking of a Geiger counter conveys the level of radiation in the immediate vicinity of the device. Though many experiments with data sonification have been explored in forums such as the International Community for Auditory Display (ICAD), sonification faces many challenges to widespread use for presenting and analyzing data.
