take an average of this evaluation mode.It is a useful algorithm to use the F-score algorithm to evaluate both precision and recall rates . The PR of the molecule determines that the precision ratio (P) and recall (R) must be large at the same time to ensure that the F score values are larger. If the precision ratio or recall rate is very low, close to 0, the direct result of the PR value is very low, approaching 0, that is, F score is also very low.At this point we compare three algorithms, we

Analogy to the servlet component, I give my own definition to the components of the Auraro framework:
1. What is a component.
Components are compliant, with a certain function, can be run independently of the software module
2. What is a container.
The container provides the environment for the operation of the component, managing the lifecycle of the component

To learn about machine learning, you must master a few mathematical knowledge. Otherwise, you will be confused (Allah was in this state before ). Among them, data distribution, maximum likelihood (and several methods for extreme values), deviation and variance trade-offs, as well as feature selection, model selection, and hybrid model are all particularly important. Here I will take you to review the releva

For example, if a strange guy is in a temporary state, he or she can move it back and forth and check whether any hero unit is near,
When it is detected that a hero is approaching, it is converted to status 2, attacking the hero.
All, we also need a function to convert the state
void converToState(EState dstState){curState = dstState;}
The above state machine is implemented in C language.

In addition, the algorithm itself needs to k-clustering the data, which may be difficult for big data to achieve, so the overall efficiency of the algorithm has yet to be tested.
