2. The method of claim 1 wherein said neural network comprises a CNN (Convolutional Neural Network).
2. The method of claim 1 wherein said neural network comprises a CNN (Convolutional Neural Network). 7. The method of claim 2 wherein: iteratively learning and adapting said neural network, further comprises: iteratively learning and adapting said neural network by fine tuning said neural network wherein said fine tuning said neural network comprises utilizing a cascade of coarse-to-fine adaptations so as to iteratively learn and adapt said neural network, wherein said coarse-to-fine manner includes said cascade of coarse-to-fine adaptations and wherein said fine tuning further includes utilizing all available samples from a target domain even if said all available samples are derived from different scenarios, and wherein said neural network is subsequently fine-tuned again with respect to only a target subdomain that is desired to be recognized.
