When I tried J48 and NaiveBayes it was about 98% so high as well. Thus, the relative squared error takes the total squared error and normalizes it by dividing by the total squared error of the simple predictor. The wikipedia does not > retrieve anything for these terms. bigger values of $\theta$ indicate smaller values of $\hat{\theta}$, or vice versa). Check This Out

How is mean, std deviation, weight sum and precision calculated?

Mean Absolute Error The mean absolute error (MAE) has the same unit as the original data, and it can only be compared between models whose errors are measured in the same They all tell you "how far away" are your estimated values from the true value of $\theta$. ROC Area, or area under the ROC curve, is my preferred measure. Root Relative Squared Error Formula If NP is not a proper subset of coNP, why does NP not equal coNP?

An "optimal" classifier will have ROC area values approaching 1, with 0.5 being comparable to "random guessing" (similar to a Kappa statistic of 0). his comment is here Does the way this experimental kill vehicle moves and thrusts suggest it contains inertia wheels? Sep 3, 2016 Jhedy Amores · University of the Philippines Diliman Yes, I already saw that link before I asked the question, my problem was getting the A-bar.

In numeric prediction, predictions aren't just right or wrong, the error has a magnitude, and these measures reflect that.

Do Germans use “Okay” or “OK” to agree to a request or confirm that they’ve understood? If NP is not a proper subset of coNP, why does NP not equal coNP? It has some disadvantages as a performance estimate (not chance corrected, not sensitive to class distribution), so you'll probably want to look at some of the other numbers. Relative Absolute Error Formula In Weka The cost matrix is: 0 1 2 0 what improved the result for the TP Rate for second class.

What does the "stain on the moon" in the Song of Durin refer to? Relative Squared Error Unlike RMSE, the relative squared error (RSE) can be compared between models whose errors are measured in the different units. However, it can only be compared between models whose errors are measured in the same units. navigate here Are there any ways to speed up blender compositor?

Below you'll find an illustrated example of correlation. (source: http://www.mathsisfun.com/data/correlation.html) Mean absolute error is: $$MSE = \frac{1}{N} \sum^N_{i=1} | \hat{\theta}_i - \theta_i | $$ Root mean square error is: $$RMSE = Correlation tells you how much $\theta$ and $\hat{\theta}$ are related. What is the interpretation of the confusion matrix? Here there were 100 instances, so the percentages and raw numbers add up, aa + bb = 59 + 12 = 71, ab + ba = 27 + 2 = 29.
