  • Jul 31, 2019 · In the multivariate Bernoulli event model, features are independent booleans (binary variables) describing inputs, for example if a word occurs in the text or not. \[P(x_{1}, x_{2},..., x_{p}\mid y) = \prod_{i=1}^{p} p_{ki}^{x_{i}} (1-p_{ki})^{(1-x_{i})}\] where where $p_{ki}$ is the probability of class k generating the term $x_{i}$.
  • For example, self-driving cars must classify observed images as people, cars, trees, and so on; they must predict the position and speed of other cars; they must determine how far to rotate the wheels in order to make a turn. These classification and prediction problems are solved using machine learning, and the self-driving system is a form of AI.

  • In probability theory, the multinomial distribution is a generalization of the binomial distribution. For example, it models the probability of counts for each side of a k-sided die rolled n times. For n independent trials each of which leads to a success for exactly one of k categories, with each category having a given fixed success probability, the multinomial distribution gives the probability of any particular combination of numbers of successes for the various categories. When k is 2 and n

Even if these features depend on each other or upon the existence of the other features, all of these properties independently contribute to the probability that this fruit is an apple and that is why it is known as ‘Naive’.
