Convolutional factor analysis model with application to radar automatic target recognition

作者:

Highlights:

• A convolutional factor analysis model is developed and applied to RATR.

• The dictionary in our model could capture the basic structures of observed data.

• Our model has fewer parameters and can be learned better with fewer training data.

• Efficient inference is performed via VB method for our hierarchical Bayesian model.

• Experiments for real radar data show our method outperforms other related methods.
