AI总结:

本文提出一种过完备深度学习方法,通过联合学习高维嵌入及其正则化器,解决逆问题中近端和扩散方法的不足,并在多个常见逆问题上验证其有效性。

摘要:

为逆问题获得有意义的解决方案一直是一个重大挑战,在科学和工程中有许多应用。最近基于近端和扩散方法的机器学习技术显示出有前景的结果。然而,正如我们在本工作中所示,当应用于一些示例性问题时,它们也可能面临挑战。我们表明,类似于先前关于过完备字典的工作,通过将解嵌入到更高维度,可以克服这些缺点。所提出工作的新颖之处在于,我们联合设计和学习嵌入以及嵌入向量的正则化器。我们在几个示例性和常见的逆问题上证明了该方法的优点。

英文摘要:

Obtaining meaningful solutions for inverse problems has been a major challenge with many applications in science and engineering. Recent machine learning techniques based on proximal and diffusion-based methods have shown promising results. However, as we show in this work, they can also face challenges when applied to some exemplary problems. We show that similar to previous works on over-complete dictionaries, it is possible to overcome these shortcomings by embedding the solution into higher dimensions. The novelty of the work proposed is that we jointly design and learn the embedding and the regularizer for the embedding vector. We demonstrate the merit of this approach on several exemplary and common inverse problems.
