Bob 2.0 Universal Background Model (UBM) training

This algorithm is a legacy one. The API has changed since its implementation. New versions and forks will need to be updated.

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.

Unnamed group

Endpoint Name Data Format Nature
features system/array_2d_floats/1 Input
ubm tutorial/gmm/1 Output

Parameters allow users to change the configuration of an algorithm when scheduling an experiment
