Definition of Pseudocount. Meaning of Pseudocount. Synonyms of Pseudocount

- and the "pseudocount" α > 0 is a smoothing parameter, with α = 0 corresponding to no smoothing (this parameter is explained in § Pseudocount below). Additive...
- ****igns the "never-seen" symbol a fixed pseudocount of one. A variant called PPMd increments the pseudocount of the "never-seen" symbol every time the...
- is often desirable to incorporate a small-sample correction, called pseudocount, in all probability estimates such that no probability is ever set to...
- started the experiments. In a sense we made n + 2 observations (known as pseudocounts) with s + 1 successes. Although this may seem the simplest and most reasonable...
- with all (alpha) parameters set to one half. This amounts to using a pseudocount of one half for each possible outcome. Equivalently, if we write γ i...
- sample size increases. Formally, the center value corresponds to using a pseudocount of     1   2 z α 2   , {\displaystyle \ {\tfrac {\!\ 1\!\ }{2}}z_{\alpha...
- contained a small number of sequences, or only highly related sequences, pseudocounts are added to normalize the character distributions represented in the...
- 7\times 1.0\times 1.0\times 0.6\times 0.7\times 0.2\times 0.2=0.0007056.} Pseudocounts (or Laplace estimators) are often applied when calculating PPMs if based...
- vector captures the prior belief about the situation and can be seen as a pseudocount: observations of each outcome that occur before the actual data is collected...
- when n i = 0 {\displaystyle n_{i}=0} for certain i {\displaystyle i} , pseudocounts can be added. A frequency distribution shows a summarized grouping of...
