Managing computers is like managing peopleThe meaning of human existence is to do things, but a person can do things is limited, so there are more people together to do common things, but because people are unstable, if not to limit, will be wrong, so the manager was born, and the manager, first of all, he will do things, to qualify as a manager, Arranging other people to do things for themselves, become managers, what to do is to communicate with others, in this way to let others replace their

to approximate a two-item distribution when the number of experiments is very large, or to approximate the Poisson distribution at high average incidence, and also to the large number theorem. The Gaussian distribution is determined by two parameters: the desired μ and variance σ2, with the following formula:As an example of a Gaussian distribution, it is known from this graph that the desired decision determines the central position of the normal curve, and the variance determines the steep or

01 Brief Introduction The probability graph model is the product of the combination of graph theory and probability theory. It was created by Judea Pearl, a famous one. I like the probability graph model tool very much, it is a powerful multi-variable and visualized modeling tool for variable relations, mainly including two major directions: undirected graph model and directed graph model. An undirected gra

can divide n+1 maximum number of times).That is, the product of all P^maxn divided by the product of p^K, the numerator equals [1, 2, 3,.... n+1], and the denominator equals n+1. The result is consistent with the conclusion of the puzzle.Prove the process a little rubbing ....If K and maxn are found in order, the complexity is O (Num*log (p)), where num is the number of primes ,P is the prime number. If two points are found, O (Num*log (LOGP))Code: O (Num*log (p))#include #include#include#inclu

", he gives the opportunity to other priority threads, if there is only the current thread and a lower than the current thread execution priority of the thread, then the current thread will still take precedence.It is important to note that the priority here is simply the amount of opportunity to execute, and does not mean that the priority thread must be enters upgradeable to the CPU than the lower-priority line. Just the probability of execution.(5) Sleep () allows a lower-priority thread to g

Let's continue the discussion of reading Vapnik ' s book Statistical Learning theory. In the very beginning of the book, Vapnik first described and the fundamental approaches in pattern recognition:the Parametri C Estimation approach and the non-parametric estimation approach. Before introducing the non-parametric approach, which the support vector machine belongs to, Vapnik first address the Foll Owing thr

From this section, I started to go to "regular" machine learning. The reason is "regular" because it starts to establish a value function (cost function) and then optimizes the value function to obtain the weight, then test and verify. This entire process is an essential part of machine learning. The topic to learn today is logical regression, which is also a supervised

easier to solve, such as increasing the complexity of the model (increasing the branches in the decision tree, increasing the number of training in the neural network, etc.), increasing the features ("Combination", "generalization", "correlation"), and reducing the regularization factor (reference).Over fitting: The solution of overfitting usually has to re- clean the data (which causes the overfitting to be caused by the data impure), increases the sample size, reduces the model complexity, us
