Classification Accuracy is Not Enough More Performance

Recurrence of Breast CancerClassification AccuracyConfusion MatrixAccuracy ParadoxPrecisionRecallF1 ScoreSummaryThe breast cancer dataset is a standard machine learning dataset. It contains 9 attributes describing 286 women that have suffered and survived breast cancer and whether or not breast cancer recurred within 5 years.It is a binary classification problem. Of the 286 women, 201 did not suffer a recurrence of breast cancer, leaving the remaining 85 that did.I think that False Negatives are probably worse than False Positives for this problem. Do you agree? More detailed screening can clear the FaGet Price

Why accuracy alone is a bad measure for classification

Why accuracy alone is a bad measure for classification tasks, and what we can do about it. It is intuitively easy of course we mean the proportion of correct results that a classifier achieved. If, from a data set, a classifier could correctly guess the label of half of the examples, then we say its accuracy was 50%. It seems obvious that the better the accuracy, the better and more useful a classifier is.
