  • How to measure a classifier's performance when close to

    If you find it important to have a good performance on predicting the 1's, you could use the F-measure instead. It is basically the harmonic mean of recall (what portion of the actual 1's have been predicted as 1) and precision (what portion of the predicted 1's were actually a 1). For a model to score high on this measure, it needs to:

  • Hard or Soft Classification? Large-margin Unified Machines

    Mar 01, 2011· Margin-based classifiers have been popular in both machine learning and statistics for classification problems. Among numerous classifiers, some are hard classifiers while some are soft ones. Soft classifiers explicitly estimate the class conditional probabilities and then perform classification based on estimated probabilities.

  • Classification Performance Metrics NLP-FOR-HACKERS

    Now, since we have the data, we must split it two: one we’re going to use for training (80%) and another we’re going to use for testing. We test the classifier on a different set because we want to see how well our classifier generalises (how well it performs on data it hasn’t seen already).

  • Permutation Tests for Studying Classifier Performance

    We explore the framework of permutation-basedp-values for assessing the performance of classi-fiers. In this paper we study two simple permutation tests. Th e first test assess whether the classifier has found a real class structure in the data; the corresponding null distribution is estimated by per-muting the labels in the data.

    Abstract. In this chapter we compare performance of the classifiers discussed in this book, using the data sets listed in Table 1.1 on page 19. The classifiers compared in this chapter are the k-nearest neighbor classifier (k-NN), the three-layer neural network classifiers trained by BP and SI, the fuzzy classifiers with pyramidal membership functions (PYD) and ellipsoidal regions (ELD), the

  • Assessing and Comparing Classifier Performance with ROC Curves

    Nov 26, 2014· A single threshold can be selected and the classifiers’ performance at that point compared, or the overall performance can be compared by considering the AUC. Most published reports compare AUCs in absolute terms: “Classifier 1 has an AUC of 0.85, and classifier 2 has an AUC of 0.79, so classifier 1 is clearly better“. It is, however
