smoked carp

correct message bar/sample extracted The value is between 0 and 1, the closer the value is to 1, the higher the precision or recall. 3. F = Correct rate * Recall rate * 2/(correct rate + recall rate) (f value is the correct rate and recall rate of the harmonic mean) Take this example: there are 1400 carp, 300 shrimp and 300 turtles in a pond. It is now for the purpose of catching carp. 700

(such as documents, Web pages, etc.) is accurate, recall is the number of all accurate entries have been retrieved. The correct rate, recall rate and F value are the important evaluation indexes to select the target in the mixed environment. Take a look at the definition of these indicators first: Correct rate = number of correct message strips/extracted information strips Recall rate = Number of information in the correct Information Bar/sample extracted The value is between 0 and 1, the close

Consistent hashing algorithm and its implementation (consistent Hashing) One, the principle of a consistent hashing algorithm 1, the background of the emergence of a consistent hashing algorithm Technology and business are mutually reinforcing and advancing together. The generation of consistent hashing algorithms also stems from business requirements. As the business grows, a single machine has been unable to meet the needs of the business, distributed architecture emerged. In a distributed

White House, the Blue House is the second, and the British live in the Red House. It is concluded that the yellow house is the first; Norwegian people live in the yellow house. 8. The owner of the yellow house smoked Dunhill cigarettes. Norwegian smoke Dunhill cigarettes. 9. Horse farmers live next to Dunhill cigarettes.

Powder-like small medicine, general purity is too high, the amount to be small and liquid, generally 0.5%--2% small drugs are generally extracted from high-purity spices, most of them imported, for example, we often use the

The correct rate, recall rate and F value are the important evaluation indexes of the target in the mixed environment.Consider the definition of these indicators first:Correct rate = number of individuals correctly identified/number of individuals identifiedRecall rate = Number of individuals correctly identified/total number of individuals present in the test setF value = correct rate * Recall rate * 2/(correct rate + recall rate)Example: There are 1400 car
