----------------------------
Summary: Deep copy of "Network" ("o.a.c.m.ml.neuralnet")
Key: MATH-1278
URL: https://issues.apache.org/jira/browse/MATH-1278
Project: Commons Math
Issue Type: Wish
Reporter: Gilles
Assignee: Gilles
Priority: Minor
Fix For: 4.0, 3.6
It might be useful to track the changes in a ANN during the learning process.
Certain algorithms for assessing the state of a SOFM can take a long time if
the training dataset in very large.
If the state of the {{Network}} changes a lot (due to the continuing training
process) during the evaluation computation, its output will not represent the
state at some definite time.
Stopping the training process during the whole evaluation would result in a
waste of time.
An alternative is to create a deep copy of the {{Network}} instance: the
evaluation will be performed on the copy while the training can continue on the
original instance.
