This is a 60-dimensional data set on optical recognition of 10 handwritten digits. It has separate training and testing sets with 3823 and 1797 samples, respectively. Vehicle. This data set involves classification of a given

The 214 Approximate Maximal Margin Classification real-world datasets are well-known Optical Character Recognition (OCR) benchmarks. On these datasets we followed the experimental setting described by Cortes and Vapnik (1995), Freund and Schapire (1999), Li and Long

or disjoint) in combination with the CNN classifier to edit and reduce the prototypes. He also reported improvements (on five domains from the UCI repository and one optical character recognition dataset) over the baseline NN classifier if the training sets were sufficiently small and thus able to generate diverse classifiers. It is important to note that both of Alpaydin's and Skalak's work differ

ODR, DIGIT are two datasets on optical handwritten digit recognition and PEN is on pen-based handwritten digit recognition. These three datasets are available from the author. The other datasets are from the UCI repository

we experimented with the optical digit recognition data set, which is also available at UCI's ML repository. This data set has 3823 instances in a training set and 1797 in a testing set; each instance is described by 64 numeric attributes. The objective is

with missing values. The default handling in C4.5 has been used for missing values. USPS and Optdigits are optical character recognition datasets. USPS has 256 dimensions without missing values. Out of 7291 original training points, we use 1822 points as training data and the other 5469 as validation data. There are 2007 test points.
