Hamming score sklearn
WebMar 14, 2024 · Hamming Loss computes the proportion of incorrectly predicted labels to the total number of labels. For a multilabel classification, we compute the number of False Positives and False Negative per instance and then average it over the total number of training instances. Image by the Author Example-Based Accuracy WebOct 9, 2015 · If you use the default score it works, as you can see above. So you probably need to look at your predictions and understand why they are continuous (i.e. use a classifier instead of regression). Or use a different score. As an aside, if you run the regression with only one set of (column of) y values, you still get an error.

You need to create a scorer object using "AsScorer" to use any function as argument to "scoring". But as precision_recall_fscore_support returns more than one value, you need to do a slight hack to make it work.
