Bob 2.0 implementation of ISV client model training. Input template ids are strings.
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.

Given a feature vector, a GMM and a U subspace, computes the Intersession Variability Modeling (ISV) client model. Basically, this algorithm computes the latent variable z_{i} excluding possible session factors (described by the latent variable x_{i, j}).
Specific details can be found in [McCool2013]:
This algorithm relies on the Bob library.
The inputs are:
The output, model, is the latent variable z_{i} (Eq. (31) in McCool2013) that corresponds to the client offset (with the session variations suppressed).
