Combined 5x2cv f-test for comparing supervised classification learning
algorithms.
Neural Computation, 11(8):1885-1982, 1999.
**Abstract:**Dietterich (1998) reviews five statistical tests proposing the 5x2cv t test for determining whether there is a significant difference between the error rates of two classifie rs. In our experiments, we noticed that the 5x2cv t test result may vary depending on factors that should not affect the test and we propose a variant, the combined 5x2cv F test, that comb ines multiple statistics to get a more robust test. Simulation results show that this combined version of the test has lower Type I error and higher power than 5x2cv proper. - [Bailey and Elkan, 1993]

The use of the area under the ROC curve in the evaluation of machine learning
algorithms.
Pattern Recognition, 1997.
**Abstract:**In this paper we investigate the use of the area under the receiver operating characteristic (ROC) curve (AUC) as a performance measure for machine learning algorithms. As a case study we evaluate six machine learning algorithms (C4.5, Multiscale Classifier, Perceptron, Multi-layer perceptron, k-nearest neighbours, and a quadratic discriminant) on six real world medical diagnosis data sets. We compare and discuss the use of AUC to the more conventional overall accuracy and find that AUC exhibits a number of desirable properties when compared to overall accuracy: increased sensitivity in Analysis of Variance (ANOVA) tests; a standard error decreased as both AUC and the number of test samples increased; decision threshold independent; and it is invariant to a priori class probabilities. The paper concludes with the recommendation that AUC be used in preference to overall accuracy for single number evaluation of machine learning algorithms. - [Dietterich, 1998]

A unified bias-variance decomposition and its applications.
In Pat Langley, editor, Machine Learning, Proceedings of the 17th
International Conference. Morgan Kaufmann, 2000.
**Abstract:**This paper presents a unified bias-variance decomposition that is applicable to squared loss, zero-one loss, variable misclassification costs, and other loss functions. The unified decomposition sheds light on a number of significant issues: the relation between some of the previously-proposed decompositions for zero-one loss and the original one for squared loss, the relation between bias, variance and Schapire et al.'s (1997) notion of margin, and the nature of the trade-off between bias and variance in classification. While the bias-variance behavior of zero-one loss and and variable misclassification costs is quite different from that of square loss, this difference derives directly from the different definitions of loss. We have applied the proposed decomposition to decision tree learning, instance-based learning and boosting on a large suite of benchmark data sets, and made several significant observations. - [Efron, 1982]

Cascade generalization.
Machine Learning, 41(3):315-343, 2000.
**Comment:**Like Stacking, cascading is a meta-classification scheme that uses the prediction of base classifiers to improve predictions with a meta-level-classifiers. It differs from stacking in that the input is enriched with the results of a single meta classifier (instead of replacing the input with the predictions of several meta classifiers) and that several meta levels can be used, each enriching the dataset of the previous layer with one additional feature (hence a cascade of classifiers) - [Gordon and Segre, 1996]

Building algorithm profiles for prior model selection in knowledge discovery
systems.
In Proceedings of the IEEE SMC'99, International Conference on Systems,
Man and Cybernetics. IEEE press, October 1999.
**Abstract:**We propose the use of learning algorithm profiles to address the model selection problem in knowledge discovery systems. These profiles consist of metalevel feature-value vectors which describe learning algorithms from the point of view of their representation and functionality, efficiency, robustness, and practicality. Values for these features are assigned on the basis of author specifications, expert consensus or previous empirical studies. We review past evaluations of the better known learning algorithms and suggest an experimental strategy for building algorithm profiles on more quantitative grounds. Preliminary experiments have disconfirmed expert judgments on certain algorithm features, thus showing the need to build and refine such profiles via controlled experiments. - [Hilario and Kalousis, 2000]

Generalizations of the bias/variance decomposition for prediction error.
Technical report, Statistics Department, Standford University, 1997.
**Abstract:**The bias and variance of a real valued random variable, using squared error loss, are well understood. However because of recent developments in classification techniques it has become desirable to extend these concepts to general random variables and loss functions. The 0-1 (misclassifications) loss function with categorical random variables has been of particular interest. We explore the concepts of variance and bias and develop a decomposition of the prediction error into functions of the systematic and variable parts of our predictor. After providing some examples we conclude with a discussion of the various definitions that have been proposed. - [Kohavi and Wolpert, 1996]

**Comment:**When multiple performance criteria are desirable, the problem of mapping the performance results into comparable scalar values becomes apparent. In this work the ``Data Envelopment Analysis'' (DEA) methodology has been proposed as a solution to this problem. In this work, positive performance metrics like accuracy, and negative ones, like training time, are combined into a single performance ratio, called ``efficiency''. A common weighting scheme is not required; it is computed on the basis of anyone of the algorithms under inspection. Despite the intuition that such a weighting scheme would be biased, it is shown that an objective comparison of the algorithms is possible [multicriteria:KDD97]. However, a methodology of using the comparison results to select the most appropriate algorithm for a new problem is not proposed. - [Rendell and Cho, 1990]

Empirical learning as a function of concept character.
Machine Learning, 5:267-298, 1990.
**Comment:**This paper characterises and investigates the extensive role of data character as a determiner of system behavior in empirical concept learning. The main contribution is the consideration of concepts as functions or surfaces over the instance space, which 1) leads to an useful characterisation of complexity based on shape, size and concentration, and 2) allows systematic artificial data generation. The results, which focus on measures of complexity, show that shape and especially concentration have significant effects. Furthermore, the degree of degradation due to class error may depend on other data characteristics such as concept size. Inspired by some of the results, it is suggested that constructive induction focus on transforming the instance space so as to merge peaks (i.e., increase concentration). The results are based on only two learning algorithms: ID3 and PLS1. - [Ricci and Aha, 1998]

Bias,
variance, and error correction output codes for local learners.
Technical Report AIC-095-025, Naval Research Laboratory, Navy Center for
Applied Research in Artificial Intelligence, 1998.
**Abstract:**This paper focuses on a bias variance decomposition analysis of a local learning algorithm, the nearest neighbor classifier, that has been extended with error correcting output codes. This extended algorithm often considerably reduces the 0-1 (i.e., classification) error in comparison with nearest neighbor (Ricci & Aha, 1997). The analysis presented here reveals that this performance improvement is obtained by drastically reducing bias at the cost of increasing variance. We also show that, even in classification problems with few classes (m<=5), extending the codeword length beyond the limit that assures column separation yields an error reduction. This error reduction is not only in the variance, which is due to the voting mechanism used for error-correcting output codes, but also in the bias.**Keywords:**Error-correcting output codes, lazy learning algorithms, feature selection, bias/variance decomposition - [Rissanen, 1978]
