In a data matrix consider each row (profile or pattern) as a
Each column becomes a property of the objects. Two rows (objects) are similar if
their property values are "near" to each other. Statistical inference
based on object similarity is the original SLSTM concept. The concept
was first publicly referenced in support of environmental research:

Design of Experiment (DOE)
A statistical model is trained on data. DOE assures the training data
produces a stable model. DOE specifies a minimal set of critical locations in
the functional domain for a stable model. Only a stable model is suitable for validation.

system of Bob Wheeler.
Support Points, a consequence of the SLSTM
Support points are a set of key locations in the function's
domain that enable an SLSTM model to adequately represent functionality given good data coverage. "Super" support points (super vectors)
can do this task with minimal locations and minimal data coverage. This reduces model complexity
and enhances all forms of prediction including extrapolation and sparse
Validation, model performance in real time
What is the true error rate of the model?
The model must be stable. Model instability compromises realistic validation.
What is the best error rate possible given the set of data variables?
The SLSTM system appears to approach this limit.
