This stereotype was considered for one concrete case in the Brandeis program and has become deprecated.
The idea was to consider dimensionality reduction of vector spaces as a privacy mechanism.
2 data objects (data, projection matrix)
1 data object (feature vector)
Restriction: task must have exactly two input and one output data objects
Error: exactly 2 inputs and 1 output are required
Restriction: “data” property must exist under stereotype details object - “data” must have been selected and saved and “data” information must not have been deleted from model’s file
Error: data is undefined
Restriction: “projectionMatrix” property must exist under stereotype details object - “projectionMatrix” must have been selected and saved and “projectionMatrix” information must not have been deleted from model’s file
Error: projectionMatrix is undefined
Restriction: input data object fixed (by its id) in “data” property must exist also on model
Error: data object is missing
Restriction: input projectionMatrix object fixed (by its id) in “projectionMatrix” property must exist also on model
Error: projectionMatrix object is missing
Restriction: data and projectionMatrix objects must be different data objects - they must have different ids
Error: data and projectionMatrix must be different objects
