From rule to statistic and statistical language model

context-sensitive characteristics of the establishment of mathematical models, also known as statistical language model. For the statistical language model, Jarinik is described as follows: If a sentence is reasonable, see how likely the sentence will appear in the corpus, which is measured by probability. The Mathematical description of the statistical language model is as follows:Suppose S denotes a meaningful sentence, consisting of a sequence of words w1,

insurance companies and. (Basically the reader is unintelligible). before the 1970s, the scientists tried to determine whether the word sequence was grammatically correct or not, but the road was not moving. Jarinik looked at the problem from another angle, and it was pretty done with a simple statistical language model. Jarinik's starting point is simple: If a sentence is reasonable, see how likely it is. As for probability, it is measured by probabilities. The first sentence appears the mos

Why the neural network should be normalized

With the neural network of small partners know that the data needs to be normalized, but why to do normalization, the problem has always been ambiguous, and there is no more than the answer on the net, the small series spent a period of time, made some research, give us a careful analysis, why do normalization: 1. Numerical problems. There is no doubt that normalization can indeed avoid some unnecessary numerical problems. The magnitude of the input variable does not cause a numerical problem,

NLP (iii) _ Statistical language model

ConceptStatistical language model: It is a mathematical model to describe the inherent law of natural language. Widely used in various natural language processing problems, such as speech recognition, machine translation, Word segmentation, part-of-speech tagging, and so on. Simply put, a language model is a model used to calculate the probability of a sentence.That is P (w1,w2,w3 .... WK). Using a language model, you can determine which word sequence

, trail surrogate]: Two 16bits code units, with the value ranges of 0xd800 .. 0xdbff and 0xdc00 .. 0 xdfff. The range of the Code unit obtained in BMP is 0x0000 .. 0 xFFFF (0xd800 .. 0xdfff is retained and does not include it). Therefore, these three segments do not overlap with each other and are easy to implement during decoding. Decoding UTF-16 Hi \ Lo Dc00 DC01 ...

Popular Understanding N-gram language model.

counting is logically completely OK, but because of the flexible nature of language, and the size of the corpus is always limited, for a slightly longer sentence, it is probably not in the corpus. For example, the following sentence: "I am looking for a restaurant to eat breakfast", intuitively, this sentence in corpus should appear a lot of times it? But if you enter this sentence into Google's search box and click Search, you will find that there is no exact match on the returned results. The
