Identity （相同性/相同率）
The extent to which two (nucleotide or amino acid) sequences are invariant.Indel（插入或删除的缩略语）
An insertion or deletion in a sequence alignment.Information content (of a scoring matrix)
A representation of the degree of sequence conservation in a column of ascoring matrix representing an alignment of related sequences. It is also the number of questions that must be asked to match the column to a position in a test sequence. For bases, the max-imum possible number is 2, and for proteins, 4.32 (logarithm to the base 2 of the number of possible sequence characters).Information theory（信息理论）
A branch of mathematics that measures information in terms of bits, the minimal amount of structural complexity needed to encode a given piece of information.Input layer（输入层）
The initial layer in a feed-forward neural net. This layer encodes input information that will be fed through the network model.Interface definition language
Used to define an interface to an object model in a programming language neutral form, where an interface is an abstraction of a service defined only by the operations that can be performed on it.Internet（因特网）
The network infrastructure, consisting of cables interconnected by routers, that pro-vides global connectivity for individual computers and private networks of computers. A second sense of the word internet is the collective computer resources available over this global network.Interpolated Markov model
A type of Markov model of sequences that examines sequences for patterns of variable length in order to discriminate best between genes and non-gene sequences.Intranet（内部网）
Intron （内含子）
Non-coding region of DNA.Iterative（反复的/迭代的）
A sequence of operations in a procedure that is performed repeatedly.CategoryResource
