The clause defines an ML model as a data structure and the software that processes it, both fixed by the chosen algorithm. Inputs and outputs are set for the model, which is then populated or trained so that it represents the statistical properties of the training data. Its output is an approximation, produced by optimisation rather than by exact solution. The clause makes a point that matters to governance: the model is a result of its training data, so incomplete data or data that carries societal bias will show up in performance. Care with the datasets is therefore part of model quality, not a separate concern.
