How to perform Optimizing and Satisficing on N-metrics? I did not understand the concept of distributing N metrics for Optimizing and Satisficing i.e 1 for optimizing and N-1 for Satisficing.

Hey @AbdulRehman,

The high level of take away is that to compare learning algorithms we need to define a single most important metric – the optimizing metric. The other evaluation metrics we call satisfying metrics.

To compare learning algorithms:

  • Evaluate them on the test set and calculate the optimizing and satisfying metrics.
  • Discard all the algorithms that doesn’t satisfy our satisfying metric.
  • Pick the algorithm with the best value for optimizing metric.
    • If there are many algorithms with the same value for optimizing metric, pick the one with the best satisfying metric.
