Classification Accuracy is Not Enough: More …

When you build a model for a classification problem you almost always want to look at the accuracy of that model as the number of correct predictions from all predictions made. This is the classification accuracy. In a previous post, we have looked at evaluating the robustness of a model for making predictions on unseen data using cross-validation and multiple cross-validation where

Why vector normalization can improve the accuracy of ...

the reason behind it is that sometimes the measurements of the different variables are different in nature so the variance of the results is adjusted by normalizing. for instance in an age(x) vs weight (y) comparison for a set of children, the age can go from one to 10 and the weight can go from 10 pounds to 100. if you dont normalize the graphic will produce a two very weird long oval shapes ...

Accuracy and precision - Wikipedia

In the fields of science and engineering, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity's true value. The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. Although the two words precision and accuracy can ...

Using the 10:1 Ratio Rule and the 4:1 Ratio Rule - ASQ

Q: Can you explain when I should be using the 10:1 ratio rule and the 4:1 ratio rule within my calibration lab? We calibrate standards as well as manufacturing gages. A: First, I will use the right nomenclature. What the user means is 10:1 and 4:1 Test Accuracy Ratio (TAR). That is, one uses standards 4 or 10 times as accurate as the Unit Under Test (UUT) to calibrate it with.

5-10-2010· Re: 4:1 Test Accuracy Ratio or Stated Measurement Uncertainty I still remember calibrating to the Z540.1:1994 back in the 1995-2000 years. I had a 1% spec on a hand held meter, and a calibrator which had a spec of less than 0.25%, which was a TAR of better than 4:1, and so I just went forward with the calibration.
