Query: Jointly Learning Structured Analysis Discriminative Dictionary and
  Analysis Multiclass Classifier   In this paper, we propose an analysis mechanism based structured Analysis
Discriminative Dictionary Learning (ADDL) framework. ADDL seamlessly integrates
the analysis discriminative dictionary learning, analysis representation and
analysis classifier training into a unified model. The applied analysis
mechanism can make sure that the learnt dictionaries, representations and
linear classifiers over different classes are independent and discriminating as
much as possible. The dictionary is obtained by minimizing a reconstruction
error and an analytical incoherence promoting term that encourages the
sub-dictionaries associated with different classes to be independent. To obtain
the representation coefficients, ADDL imposes a sparse l2,1-norm constraint on
the coding coefficients instead of using l0 or l1-norm, since the l0 or l1-norm
constraint applied in most existing DL criteria makes the training phase time
consuming. The codes-extraction projection that bridges data with the sparse
codes by extracting special features from the given samples is calculated via
minimizing a sparse codes approximation term. Then we compute a linear
classifier based on the approximated sparse codes by an analysis mechanism to
simultaneously consider the classification and representation powers. Thus, the
classification approach of our model is very efficient, because it can avoid
the extra time-consuming sparse reconstruction process with trained dictionary
for each new test data as most existing DL algorithms. Simulations on real
image databases demonstrate that our ADDL model can obtain superior performance
over other state-of-the-arts.
