Based on conventional natural gradient algorithm (NGA) and equivariant adaptive separation via independence algorithm (EASI), a novel sign algorithm for on-line blind separation of independent sources is presented. A sign operator for the adaptation of the separation model is obtained from the derivation of a generalized dynamic separation model. A variable step-size sign algorithm rooted in NG...

Free/Open Source Software (F/OSS) is a generic term that is used for software developed under a license, which allows the use, modification and distribution of the software without claiming a fee for it. There are other terms, like “open source”, which describe a slightly different version of the F/OSS term; however the basic idea is the same in terms of usage, distribution and modification. A ...

Having an overview of the structure of information has been shown to be necessary to effectively approach the reading of it. This paper describes how programming constructs can be represented using speech and non-speech audio to provide an important ‘glance’ at program source code prior to reading it. Three methods of representing program code are investigated, using pure speech, non-speech and...
