Algorithms have at least one input and one output. All algorithm endpoints are organized in groups. Groups are used by the platform to indicate which inputs and outputs are synchronized together. The first group is automatically synchronized with the channel defined by the block in which the algorithm is deployed.

Algorithms may use functions and classes
declared in libraries. Here you can see the libraries and
import names used by this library. You don't
need to import the library manually on your code, the platform
will do it for you. Just use the object as it has been imported
with the selected named. For example, if you choose to import a
library using the name
lib, then access function
f within your code like

The ruler at 80 columns indicate suggested POSIX line breaks (for readability).

Keystroke Biometric Ongoing Competition (KBOC) is an official competition of the IEEE Eighth International Conference on Biometrics: Theory, Applications, and Systems (BTAS 2016) organized by ATVS Biometric Research Group.
Participant Block: this code (in Python) comprises the evaluation block of the KBOC16 competition.
The genuine and impostor samples are unknown except for the training samples (first 4 samples). In order to avoid overtifing of the systems and any possible misconduct, the performance evaluation is made over 100 of the 300 users. This first 100 users are representative of the complete set of 300 users. As an example, the difference between the performance of the baseline algorithms is less than 1%. The evaluation over the 300 users will be done during the final weeks of the competition. Together with this block, you can access the library kboc16_baseline_matchers (robertodaza/kboc16_baseline_matchers/5) with 3 baseline systems (see the examples below).
HOW TO PARTICIPATE: participants can modify the code of this algorithm to include their keystroke recognition systems. It is allow the use of libraries and toolboxes out of the included in this example. The participant code could be private while its results should be available for the competition organizers (in order to include it in the final competition report).
IMPORTANT: Please replace the line 108 score=1/(d+0.001) by score=-d. In some cases (with large dynamic margin between scores), the inverse of the distance can be problematic.
This table shows the number of times this algorithm has been successfully run using the given environment. Note this does not provide sufficient information to evaluate if the algorithm will run when submitted to different conditions.
