Essential Questions and Answers on Parts Per Million Corrected in "MISCELLANEOUS»UNFILED"
What does PPMC stand for?
PPMC stands for Parts Per Million Corrected.
How is PPMC calculated?
The calculation of PPMC consists of subtracting the average accuracy or error of randomly selected samples from the model's accuracy or error rate, which should be higher than baseline by several orders of magnitude (thousands or millions).
What are some applications of PPMC?
PPMC is useful in a wide range of fields that involve machine learning, such as computer vision, natural language processing, robotics and more. It can be used to compare two different models and measure how accurately they are predicting outcomes when given the same data set.
What is an example of a use case for PPMC?
For example, if there were two image recognition algorithms being compared; one algorithm achieving 99% accuracy on a given data set and another achieving 98% accuracy on the same data set - after calculating the respective parts per million corrected scores, it would become clear that the first algorithm was more accurate than the second by at least 1 part per million corrected score.
What other metrics might be used alongside PPMC?
In order to get a full picture of each model's performance and better understand their strengths and weaknesses relative to each other, additional metrics such as precision and recall may also be computed to complement parts per million corrected scores.
Final Words:
Parts Per Million Corrected (PPMC) is a useful metric for measuring accuracy in machine learning models relative to random selection or baseline accuracies by several orders of magnitude (thousands or millions). By answering frequently asked questions about what it measures, how it's calculated and potential use cases, we can better understand its capabilities when comparing two different models in any domain requiring machine learning solutions.
