What is the literacy rate?

1, the recognition rate refers to randomly inverting some bits in each of the 26 samples (the inverted bits are obtained according to the noise rate) to obtain noisy test samples, inputting 100 times, and then statistically outputting the correct number.

2, 2 Results and Discussion The predictive ability of a model is often tested by recognition rate and prediction rate. The recognition rate refers to the prediction ability of the model to the training database, and the prediction rate is used to evaluate the prediction ability of the model to the test set. Self-test is often used to evaluate the recognition rate, and eross-validation is often used to evaluate the prediction rate.

3. Recognition rate refers to the rate of recognizing correct characters. There are many factors that affect the recognition rate, such as the inaccurate brightness level of scanning equipment, which will reduce the accuracy of scanning files and cause the recognition rate to decline.

4. The so-called recognition rate refers to how many samples of a certain type fall within the area of this model, while the rejection rate refers to the degree of rejection of a certain sample model for unknown samples that do not belong to this type.

5. There are two recognition rates. One is the probability that the correctly segmented Chinese character image is correctly recognized, which is called the single character recognition rate, and the other is the probability that the recognition result is correctly recognized relative to the manuscript, which is called the system recognition rate.

6. The recognition rate refers to the correct probability of the above three methods in fault diagnosis of six samples. Dominant solution means that every element of the objective function is greater than or less than every element of some other feasible solution.

7. The principal component PCs numbers are 3, 6, 10 and 16 respectively, and the recognition rate is defined as η = the total number of correctly recognized characters and the total number of test samples (2007)× 100%.
