A note of caution: comparison of different classifiers is not an easy task. Before you get into ranking of methods using the numbers presented in tables below please note the following facts.
Many results we have collected give only a single number (even results from the StatLog project!), without standard deviation. Since most classifiers may give results that differ by several percent on slightly different data partitions single numbers do not mean much.
Leaveoneout tests have been criticized as a basis for accuracy evaluation, the conclusion is that crossvalidation is safer, cf:
Kohavi, R. (1995). A study of crossvalidation and bootstrap for accuracy estimation and model selection.
In: Proc. of the 14th Int. Joint Conference on Artificial Intelligence, Morgan Kaufmann, pp. 11371143.
Crossvalidation tests (CV) are also not ideal. Theoretically about 2/3 of results should be within a single standard deviation from the average, and 95% of results should be within two standard deviations, so in a 10fold crossvalidation you should see very rarely reuslts that are beter or worse than 2xSTDs. Running CV several times may also give you different answers. Search for the best estimator continues. Cf:
Dietterich, T. (1998) Approximate statistical tests for comparing supervised classification learning algorithms. Neural Computation, 10 (7), 18951924;
Nadeau C, Bengio Y. (1999) Inference for the Generalization Error. Tech. rep. 99s25, CIRANO, J. Machine Learning (Kluver, in print).
Even the best accuracy and variance estimation is not sufficient, since performance cannot be characterized by a single number. It should be much better to provide full Receiver Operator Curves (ROC). Combining ROC with variance estimation would be ideal.
Unfortunately this still remains to be done. All we can do now is to collect some numbers in tables.
Our results are obtained usually with the GhostMiner package, developed in our group.

Thyroid, From UCI repository, dataset "anntrain.data":
A Thyroid database suited for training ANNs.
3772 learning and 3428 testing examples; primary hypothyroid, compensated hypothyroid, normal.
Training: 93+191+3488 or 2.47%, 5.06%, 92.47%
Test: 73+177+3178 or 2.13%, 5.16%, 92.71%
21 attributes (15 binary, 6 continuous); 3 classes
The problem is to determine whether a patient referred to the clinic has hypothyroid. Therefore three classes are built: normal (not hypothyroid), hyperfunction and subnormal functioning. Because 92 percent of the patients are not hyperthyroid. A good classifier must be significant better than 92%.

SVM with linear and Gaussian kernels gives quite poor results on this data.
3 crisp logical rules using TSH, FTI, T3, on_thyroxine, thyroid_surgery, TT4 give 99.3% of accuracy on the test set.
Contains medical records of 536 patients admitted to a universityaffiliated Tokyobased hospital, with four types of hepatobiliary disorders: alcoholic liver damage, primary hepatoma, liver cirrhosis and cholelithiasis. The records included results of 9 biochemical tests and sex of the patient. The same 163 cases as in [Hayashi et.al] were used as the test data.
FSM gives about 60 Gaussian or triangular membership functions achieving accuracy of 75.575.8%. Rotation of these functions (i.e. introducing linear combination of inputs to the rules) does not improve this accuracy. 10fold crossvalidation tests on the mixed, training plus test data, give similar results. The best results were obtained with the K* method based on algorithmic complexity optimization, giving 78.5% on the test set, and kNN with Manhattan distance function, k=1 and selection of features (using the leaveoneout method on the training data, features 2, 5, 6 and 9 were removed), giving 80.4% accuracy. Simulated annealing optimization of the scaling factors for the remaining 5 features give 81.0% and optimizing scaling factors using all input features 82.8%. The scaling factors are: 0.92, 0.60, 0.91, 0.92, 0.07, 0.41, 0.55, 0.86, 0.30. Similar accuracy is obtained using multisimplex method for optimization of the scaling factors.

Training 4435 test 2000 cases, 36 semicontinous [0 to 255] attributes (= 4 spectral bands x 9 pixels in neighbourhood) and 6 decision classes: 1,2,3,4,5 and 7 (class 6 has been removed because of doubts about the validity of this class).
The StatLog database consists of the multispectral values of pixels in 3x3 neighbourhoods in a satellite image, and the classification associated with the central pixel in each neighbourhood. The aim is to predict this classification, given the multispectral values. In the sample database, the class of a pixel is coded as a number.

The original database was generated from Landsat MultiSpectral Scanner image data. The sample database was generated taking a small section (82 rows and 100 columns) from the original data. One frame of Landsat MSS imagery consists of four digital images of the same scene in different spectral bands. Two of these are in the visible region (corresponding approximately to green and red regions of the visible spectrum) and two are in the (near) infrared. Each pixel is a 8bit binary word, with 0 corresponding to black and 255 to white. The spatial resolution of a pixel is about 80m x 80m. Each image contains 2340 x 3380 such pixels.
The database is a (tiny) subarea of a scene, consisting of 82 x 100 pixels. Each line of data corresponds to a 3x3 square neighbourhood of pixels completely contained within the 82x100 subarea. Each line contains the pixel values in the four spectral bands (converted to ASCII) of each of the 9 pixels in the 3x3 neighbourhood and a number indicating the classification label of the central pixel. In each line of data the four spectral values for the topleft pixel are given first followed by the four spectral values for the topmiddle pixel and then those for the topright pixel, and so on with the pixels read out in sequence lefttoright and toptobottom. Thus, the four spectral values for the central pixel are given by attributes 17,18,19 and 20. If you like you can use only these four attributes, while ignoring the others. This avoids the problem which arises when a 3x3 neighbourhood straddles a boundary.

This dataset has been used in two kinds of experiments:
1. The "aspectangle independent" experiments use all 208 cases with 13fold crossvalidation, averaged over 10 runs to get std.
2. The "angle independent experiments" use training / test sets with 104 vectors each. Class distribution in training is 49 + 55, in test 62 + 42.
Estimation of L1O on the whole dataset (Opper and Winther) give 78.2% only; is the test so easy? Some of this results were made without standardization of the data, which is here very important!

Parameters in SVM were optimized, that is in each CV different paramters were used, so only approximate value can be quoted. If they are fixed to C=1000, s=1 results are a bit worse.

These data are the results of a chemical analysis of wines grown in the same region in Italy but derived from three different cultivars. The analysis determined the quantities of 13 constituents found in each of the three types of wines.
Class distribution: 178 cases = [59, 71, 48] in Class 13;
13 continuous attributes: alcohol, malicacid, ash, alkalinity, magnesium, phenols, flavanoids, nonanthocyanins, proanthocyanins, color, hue, OD280/D315, proline.

Stalog Data: splice junctions are points on a DNA sequence at which `superfluous' DNA
is removed during the process of protein creation in higher organisms.
The problem posed in this dataset is to recognize, given a sequence of
DNA, the boundaries between exons (the parts of the DNA sequence retained
after splicing) and introns (the parts of the DNA sequence that are spliced
out).
This problem consists of two subtasks: recognizing exon/intron boundaries
(referred to as EI sites), and recognizing intron/exon boundaries (IE sites).
(In the biological community, IE borders are referred to a "acceptors''
while EI borders are referred to as "donors''.)

Number of attributes: originally 60 attributes {a,c,t,g}, usually converted to 180 binary indicator variables {(0,0,0), (0,0,1), (0,1,0), (1,0,0)}, or 240 binary variables.
Much better performance is generally observed if attributes closest to the junction are used (middle). In the StatLog version (180 variables), this means using attributes A61 to A120 only.
