Description
The data is about the recognition of handwritten numbers from 0 to 9.
There are 30 writers in the training dataset and each participant are asked to write 250 digits in random order.
Without missing data, this dataset has 7494 observations.
The experiment uses WACOM tablet, which has 500 x 500 pixel resolutions and normalized it to a maximum scale of 100.
The researcher considers spatial resampling.
Thus, for each digit, eight pairs of 2 dimensional (x axis and y axis) locations are recorded, which makes this dataset have 16 dimensional predictor variables.
Usage
1
Format
A data frame with 2219 obsevations on 17 variables.
The first column to the 16th column represent resampled values of the pairs of points.
The 17th column presents the digit (0 to 9).
