Probability-based classification method: Naive BayesianBayesian decision theoryNaive Bayes is part of the Bayesian decision theory, so let's take a quick and easy look at Bayesian decision theory before we talk about naive Bayes.The core idea of Bayesian decision-making theory : Choose the decision with the highest probability. For example, we graduate to choose the direction of employment, the

/** Classical probability algorithm,* $PROARR is a pre-set array,* Suppose array is: Array (100,200,300,400),* Start is to filter the first number from the probability range of 1,1000 within the range of his probability of occurrence,* If not, then the probability space, that is, the value of K minus the

The Monte Hall problem is a mathematical game problem derived from game theory. It is roughly from the TV game program "Let's Make a Deal ". The name of the question comes from Zhu's role as Monty.Hall ). In this game, contestants will see three closed doors, one of which is followed by a car. Then the contestant selects a door and the host opens one of the remaining two doors to reveal one goat. Afterwards, the host will ask the contestants if they want to change to another closed door. This is

Title Description:Write a random shuffle function. 52 of the required wash out! All kinds of combinations are equal probabilities. That is, the probability of a combination you wash out is 1/(52!). Assume that you have a perfect random number generator.Problem Solving Ideas:This is a probability problem.Random Shuffle, the purpose is to do randomness, require each card to appear the

Problem: A small island, represented as a square n × N, from (0, 0) to (N-1, N-1), a person standing on the island, location (x, y), he can go up and down, one step is a grid, and the possibility of selecting top, bottom, and left is the same. When he leaves the island, it means death. If he is going to take K steps, how likely is his death? Analysis I: The probability is required. First, the number n of all paths and the number M of outbound paths a

When a programmer begins to learn Java, his first question should be how to choose a book as a guide to learning Java. This problem also shows that, compared to other tutorials and blogs, Java

Question: A function Foo can return 0, 1 with a probability of 3: 2. Now it is required to write a fun2 and return 0, 1 with an equi probability. This Is What Baidu says when I see an interview question. One function fun can return values 0 and 1. The probability of returning values 0 and 1 is 1/2. How can we use this function to get another function fun2 so th

Skew (skewness) In probability theory and statistics, skewness measures the asymmetry of the probability distribution of a real random variable. The value of skewness can be positive, negative or even undefined. In quantity, a negative bias (negative bias) means that the tail of the left side of the probability density function is longer than the right,

The maximum likelihood estimate is a wonderful thing, and I think the person who invented this estimate is particularly talented. If it were me, it would be hard to think of it.The maximum likelihood estimation and Bayesian estimation represent the viewpoints of the frequency and Bayesian factions respectively. The frequency faction thinks, the parameter is the objective existence, only then is unknown. Therefore, the frequency faction most concerned about the maximum likelihood function, as lon
