In the field of machine learning, probability distribution plays an important role in the understanding of data. Whether it is effective or noisy data, if you know the distribution of data, then in the data modeling process will be a great revelation. This paper summarizes several common probability distributions, such as the distribution of discrete random variables representing the Bernoulli distribution
{Code ...} the result is {code ...} after running it for many times, it is almost the same, and the actual user's results will be a bit problematic {code ...} how can we minimize the fluctuation when there is a small probability?

A probability function called $ x $. And has the following properties:
$ P_ I \ geqslant 0, P_1 + p_2 + \ DOTS = 1 $
The probability function of $ x $ shows how all probability 1 is allocated among its possible values. Therefore, it is also called the "probability distribution" of th
Network packet error probability and packet error probabilityTcp and udp checksum are weak. Simply put, the sum of all values is reversed. Even errors in order cannot be prevented, and there are not many digits, 16 bits.

In the past two days, we have been looking at particle filtering and EKF. The anterior probability and posterior probability are mixed up. I checked it online and finally figured it out.
A prior probability is a subjective probability. Then, based on the experiment, the Bayes formula is used to calculate the posterior
