Data binning, also called data discrete binning or data bucketing, is a data pre-processing technique used to reduce the effects of minor observation errors. The original data values which fall into a given small interval, a bin , are replaced by a value representative of that interval, often a central value ( mean or median ).
The problem with this method was that only a tiny fraction of the sequences carried a marker gene, leaving most of the data unassigned. Modern binning techniques use both previously available information independent from the sample and intrinsic information present in the sample.
Typically data is discretized into partitions of K equal lengths/width (equal intervals) or K% of the total data (equal frequencies). [1] Mechanisms for discretizing continuous data include Fayyad & Irani's MDL method, [2] which uses mutual information to recursively define the best bins, CAIM, CACC, Ameva, and many others [3]
The maximal information coefficient uses binning as a means to apply mutual information on continuous random variables. Binning has been used for some time as a way of applying mutual information to continuous distributions; what MIC contributes in addition is a methodology for selecting the number of bins and picking a maximum over many possible grids.
As most tree based algorithms use linear splits, using an ensemble of a set of trees works better than using a single tree on data that has nonlinear properties (i.e. most real world distributions). Working well with non-linear data is a huge advantage because other data mining techniques such as single decision trees do not handle this as well.
Data binning: a data pre-processing technique. Binning (metagenomics): the process of classifying reads into different groups or taxonomies. Product binning: in semiconductor device fabrication, the process of categorizing finished products. Pixel binning: the process of combining charge from adjacent pixels in a CCD image sensor during readout.
Semantic data mining is a subset of data mining that specifically seeks to incorporate domain knowledge, such as formal semantics, into the data mining process.Domain knowledge is the knowledge of the environment the data was processed in. Domain knowledge can have a positive influence on many aspects of data mining, such as filtering out redundant or inconsistent data during the preprocessing ...
The data generated by metagenomics experiments are both enormous and inherently noisy, containing fragmented data representing as many as 10,000 species. [1] The sequencing of the cow rumen metagenome generated 279 gigabases , or 279 billion base pairs of nucleotide sequence data, [ 28 ] while the human gut microbiome gene catalog identified 3. ...
