Class Specific or Shared? A Hybrid Dictionary Learning Network for Image Classification

  title={Class Specific or Shared? A Hybrid Dictionary Learning Network for Image Classification},
  author={Shuai Shao and Yanjiang Wang and Baodi Liu and Rui Xu and Ye Li},
Dictionary learning methods can be split into two categories: i) class specific dictionary learning ii) class shared dictionary learning. The difference between the two categories is how to use the discriminative information. With the first category, samples of different classes are mapped to different subspaces which leads to some redundancy in the base vectors. For the second category, the samples in each specific class can not be described well. Moreover, most class shared dictionary…

Sparse Representation Based Fisher Discrimination Dictionary Learning for Image Classification

The proposed FDDL model is extensively evaluated on various image datasets, and it shows superior performance to many state-of-the-art dictionary learning methods in a variety of classification tasks.

Label Consistent K-SVD: Learning a Discriminative Dictionary for Recognition

A label consistent K-SVD (LC-KSVD) algorithm to learn a discriminative dictionary for sparse coding and introduces a new label consistency constraint called "discriminative sparse-code error" to enforce discriminability in sparse codes during the dictionary learning process.

By introducing the dual form of dictionary learning, an explicit relationship between the bases vectors and the original image features is represented, which enhances the interpretability and results in superior performance compared with conventional classification algorithms.

Learning Dictionary of Discriminative Part Detectors for Image Categorization and Cosegmentation

The proposed method to learn an over-complete dictionary is based on extending the K-SVD algorithm by incorporating the classification error into the objective function, thus allowing the performance of a linear classifier and the representational power of the dictionary being considered at the same time by the same optimization procedure.

Between-Class Learning for Image Classification

This paper proposes a simple mixing method using internal divisions, which surprisingly proves to significantly improve performance and proposes a mixing method that treats the images as waveforms, which leads to a further improvement in performance.

Deep Learning Based Feature Selection for Remote Sensing Scene Classification

A novel deep-learning-based feature-selection method is proposed, which formulates the feature- selection problem as a feature reconstruction problem, and an iterative algorithm is developed to adapt the DBN to produce the inquired reconstruction weights.
