WebbC-Support Vector Classification. The implementation is based on libsvm. The fit time scales at least quadratically with the number of samples and may be impractical beyond tens of thousands of samples. For large datasets consider using LinearSVC or SGDClassifier instead, possibly after a Nystroem transformer. Webb29 nov. 2015 · The unweighted accuracy is 67.20%, while weighted accuracy is 62.91%, an impressive improvement indeed, with approximately 5% and 30%, respectively. This shows that careful consideration during data preparation can indeed influence the system performance, even though the raw data is actually identical!
Webb'weighted': Calculate metrics for each label, and find their average weighted by support (the number of true instances for each label). This alters ‘macro’ to account for label … WebbModel parameters, tags, performance metrics ¶. MLflow and experiment tracking log a lot of useful information about the experiment run automatically (start time, duration, who ran it, git commit, etc.), but to get full value out of the feature you need to log useful information like model parameters and performance metrics during the experiment run.
