| ALPHABET |
A finite, nonempty set an ALPHABET.The LENGTH or cardinality of an alphabet A will be referred to as |A|. |
| 字母表 |
有限、非空、有序的集合 |
| SYMBOL |
The elements {a 1 ,...,a m } of an alphabet are called SYMBOLS |
| 符号 |
字母表内的元素 |
| SEQUENCE |
A series S = (s 1 ,s 2 ...) of symbols s i from an alphabet A is called SEQUENCE . |
| 序列 |
有序的符号构成一个序列 通常简写为 S = s 1 s 2 ... |
| PROBABILITY |
Let S = (s 1 ,...,s n ) a finite-length sequence with |S| = n over A = {a 1 ,...,a m }. Also let |S| a i the frequency of a i in S. Then we define P(a i ) := (|S| a i)/n as the PROBABILITY of a i (in S). |
| 符号实际概率 |
符号在一个有限长序列中出现的概率 |
