Noisy data are data with a large amount of additional meaningless information in it called noise. [1] This includes data corruption and the term is often used as a synonym for corrupt data. [1] It also includes any data that a user system cannot understand and interpret correctly. Many systems, for example, cannot use unstructured text. Noisy ...
Noisy text analytics is a process of information extraction whose goal is to automatically extract structured or semistructured information from noisy unstructured text data. While Text analytics is a growing and mature field that has great value because of the huge amounts of data being produced, processing of noisy text is gaining in ...
In information theory, the noisy-channel coding theorem (sometimes Shannon's theorem or Shannon's limit), establishes that for any given degree of noise contamination of a communication channel, it is possible (in theory) to communicate discrete data (digital information) nearly error-free up to a computable maximum rate through the channel.

For most data sets and domains, this situation does not arise often and has little impact on the clustering result: [4] both on core points and noise points, DBSCAN is deterministic. DBSCAN* [ 6 ] [ 7 ] is a variation that treats border points as noise, and this way achieves a fully deterministic result as well as a more consistent statistical ...
Scammers are using fake toll-collection texts to steal bank information, authorities warned. Avoid clicking suspicious links and report scams to protect your personal data.
Texas Attorney General Ken Paxton said Allstate created the "world's largest driving behavior database," with data on more than 45 million Americans, by paying mobile app developers millions of ...
In the simple version above, the signal and noise are fully uncorrelated, in which case + is the total power of the received signal and noise together. A generalization of the above equation for the case where the additive noise is not white (or that the / is not constant with frequency over the bandwidth) is obtained by treating the channel as many narrow, independent Gaussian ...
