Big backpack Question: There are n a weight and price value respectively W[i] and V[i] project. The total weight of these products does not exceed the W project. Finds the maximum sum value for all selected scenario price values.Among them, 1≤n≤40, 1≤w[i], v[i]≤10^15, 1≤w≤10^15.The first feeling of this problem is the normal 01 backpack.Just after reading the data range will be found. This time the value and weight can be very large values, compared to n is smaller. The complexity of solving a b

We always produce a lot of text in our daily life, and if each text is stored as a document, then each document is an ordered sequence of words d= (W1,W2,⋯,WN) from human observation.
Corpus containing M-piece documents
The purpose of the statistical text modeling is to ask how the word sequences in the corpus are generated. Statistics are described by people as guessing the game of God, all the corpus texts produced by human beings we can all be see

1. Language Model (LM) Overview
Children who have done NLP tasks should know what a language model is, simply put, if we think of a sentence s as a collection of several (n) Word w, then the probability of this sentence being generated is:P (s) =p (w1,w2,..., wn) =p (W1) p (W2|W1) p (w3|w1,w2) ... p (wn|w1,..., wn−1)

} Suppose there are simultaneous W1, W2, W3, W4, W5, W6 concurrent request writes. Part B code allows the W1 to compete with the mutex resource to acquire the lock. W1 adds the data it wants to write to the Writers_ queue, when the queue has only one W1, so it goes smoothly buildbatchgroup . When the Mutex_ mutex is released when running to 34 rows, Mutex_ can be released here because other writes do not meet the team's first condition and will not

Main statistical models: n-gram and Hidden Markov Model (Hidden Markov Model, hmm)
1.2.1n-gram model idea
The model is based on the assumption that the appearance of the N words is only related to the previous N-1 words, but not to any other words, the probability of a sentence is the product of the probability of occurrence of each word.
We give a word and then guess what the next word is. What do you think of the next word when I say "yanzhaomen? I thi
modify the cyclic variables J and I? After reading it for half a day, I realized that I wanted to copy a part of the Matrix to a temporary array. In fact, this replication is completely unnecessary. Later I spent a few hours doing a huge reconstruction of this simple program. During this period, we constantly find extremely repeated code, and even some duplicate code is inconsistent (that is, some of the copied code has been modified and corrected ). Let's take a look at this Code:If (S [1] [1]
