Definition of prime number:The number of integers in a natural number greater than 1, except 1 and the integer itself, cannot be divisible by other natural numbers. In other words, the natural number of only two positive factors (1 and self) is

1, least common multipleFinding the least common multiple of two numbers is a very common operation. For example, the minimum male of 3 and 5 is 15. The least common multiple of 6 and 8 is 24.The following code asks for the least common multiple of

When I was reading foreign textbooks, I found a concept of Mean Squared Error (mean variance). I went to Zhejiang University's book probability theory and mathematical statistics, the mean variance and standard deviation are defined as a concept

Variance and standard deviation The sum of squares of the differences between each data and the average sample is called the sample variance. The arithmetic square root of the sample variance is called the sample standard deviation. Both the sample

You can use the searcher. Explain (query, int DOC) method to view the specific composition of a document's score. In Lucene, the score is calculated by TF * IDF * boost * lengthnorm. TF: the square root of the number of times the query word appears
