WebOct 4, 2024 · For instance, if a binary classification data set has a class imbalance ratio of 90:10, then a model with 90% classification accuracy is a non-informative one. In order to tackle these limitations, the F1 score is another metric, which is defined as the harmonic mean of precision and recall. Weba quick way to do this - if you do not require sparse matrix - is to create an identity matrix, of size at least the max (v), then to create your indicator matrix by extracting indexes from v: m = max (V); I = eye (m); V = I (V, :); Share Improve this answer Follow edited Jun 29, …
