In method 1, you calculate accuracy as 1-CV_Error which is reliable and makes sense. In method 2, you give samples to trained classifier for the second time. The obtained accuracy is not much reliable as the method 1. Of course, you get different accuracy from method 1 and method 2. And I think the first method for caculating accuracy is enough.

To estimate the accuracy of a test, we should calculate the proportion of true positive and true negative in all evaluated cases. Mathematically, this can be stated as: Accuracy = TP + TN TP + TN + FP + FN . Sensitivity: The sensitivity of a test is its ability to determine the patient cases correctly. To estimate it, we should calculate the proportion of true positive in patient cases

Formula to calculate accuracy. So as to know how accurate a value is, we find the percentage error. Example: Suppose the known length of a string is 6cm, when the same length was measured using a ruler it was found to be 5.8cm. Calculate the accuracy of the ruler. 100% – 3% = 97% Therefore, the results are 97% accurate. Prev Article Next Article

If the analyst touches the weight with their finger and obtains a weight of 1.0005 grams, the total error = 1.0005 -1.0000 = 0.0005 grams and the random and systematic errors could be estimated to be 0.0001 and 0.0004 grams respectively.

August 2016 Solution Accepted In general you are right and you should ignore training error completely. It is not telling you really anything useful. For example, a K-NN learner with k=1 will always deliver 100% accuracy on the training data set. But this does not mean that it can classify ANYTHING correctly on any non-training data point.

In this case, what will be training accuracy? From each of 10 folds you can get a test accuracy on 10% of data, and a training accuracy on 90% of data. In python, method cross_val_score only calculates the test accuracies.
Accuracy = T P + T N T P + T N + F P + F N. Where TP = True Positives, TN = True Negatives, FP = False Positives, and FN = False Negatives. Let's try calculating accuracy for the following model...
To measure your employees’ learning, consider observing them before and after they attend the online training, so that you can compare their results. The true test of a training program’s success is whether the employees have the knowledge and skills necessary to do their job effectively and efficiently. Use scenarios and simulations.
The accuracy can be defined as the percentage of correctly classified instances (TP + TN)/ (TP + TN + FP + FN). where TP, FN, FP and TN represent the number of true positives, false negatives, false positives and true negatives, respectively. also you can use standard performance measures: Sensitivity = TP / TP + FN Specificity = TN / TN + FP
