The plan is to make the SDRClassifier as the default usage for Network API, OPF etc. The next step would be to replace CLAClassifier for the demos. Unless we find out cases where CLAClassifier give better performance than SDRClassifier, the CLAClassifier will be deprecated.
The SDRClassifier typically results in fewer outlier predictions than CLAClassifier as it not only reinforce correct predictions, but also punish incorrect ones during learning. The learning rules for SDRClassifier are derived under the maximum likelihood framework, whereas the CLAClassifier used heuristic learning rules.
