pyeer 0.1.0

A python package with utilities to calculate Equal Error Values, operation points and to plot the probability error curves.

PyEER is a python package with utilities to calculate Equal Error Values, operation points and to plot the probability error curves.

Installing

pip install pyeer

Input file formats

On this epigraph the two different input file formats supported will be described.

Histogram format

Restrictions: Only integer scores are supported

File format: Each line contains the number of scores equals to the index of the line in the file (starting from zero). For example, given a file:

123

12

212

321

…

…

…

The above file example indicates that there are 123 scores equals to 0, 12 scores equals to 1, 212 scores equals to 2, 321 scores equals to 3 and so on.

Recommendations: Use this format for very large experiments.

Note: Only impostor scores file can mimic this format.

Non-Histogram format

Restrictions: None. Integer and float scores are both supported.

File format: All the scores one by line

Usage

console cmd: geteerinf

Examples:

To print the script help

python geteerinf -h

One experiment (Non-histogram format):

python geteerinf -p "example_files/non_hist/" -i "exp1_false" -g "exp1_true" -e "exp1"

More than one experiment (Non-histogram format):

python geteerinf -p "example_files/non_hist/" -i "exp1_false,exp2_false" -g "exp1_true,exp2_true" -e "exp1,exp2"

One experiment (Histogram format):

python geteerinf -p "example_files/hist/" -i "exp1_false" -g "exp1_true" -e "exp1" -ht

Note: To run the above examples you can download the example files from the project site on Gitlab or extract them from inside the package installation
