WebNov 23, 2024 · To better understand our model’s accuracy, we need to use different ways to calculate it. Multilabel Accuracy or Hamming Score. In multilabel settings, Accuracy (also called Hamming Score) is the proportion of correctly predicted labels and the number of active labels (both real and predicted). Where. n is the number of samples. WebIf you want to improve the accuracy, think of improving accuracy computing with k-fold cross validation. There are several ways to try to improve, for example: a) get more data/better data.
