提出了一种卷积递归稀疏自动编码器模型。该模型由一个稀疏编码器和一个线性卷积译码器组成，稀疏编码器是学习ISTA(LISTA)方法的卷积扩展。我们的策略提供了一种简单的方法来学习任务驱动的稀疏卷积字典(CD)，并在所学习的字典上产生近似卷积稀疏码(CSC)。我们训练模型使重建损失最小化，通过梯度下降和反向传播，在图像修复中取得了与KSVD图像去噪和领先的CSC方法相当的效果，只需要它们的一小部分运行时间。

英文摘要：
  We propose a convolutional recurrent sparse auto-encoder model. The model consists of a sparse encoder, which is a convolutional extension of the learned ISTA (LISTA) method, and a linear convolutional decoder. Our strategy offers a simple method for learning a task-driven sparse convolutional dictionary (CD), and producing an approximate convolutional sparse code (CSC) over the learned dictionary. We trained the model to minimize reconstruction loss via gradient decent with back-propagation and have achieved competitive results to KSVD image denoising and to leading CSC methods in image inpainting requiring only a small fraction of their run-time.
