Deploying Image Deblurring across Mobile Devices: A Perspective of Quality and Latency
Cheng-Ming Chiang, Yu Tseng, Yu-Syuan Xu +13
Recently, image enhancement and restoration have become important applications on mobile devices, such as super-resolution and image deblurring. However, most state-of-the-art netw…
Products of random walks on finite groups with moderate growth
Guan-Yu Chen, Takashi Kumagai
In this article, we consider products of random walks on finite groups with moderate growth and discuss their cutoffs in the total variation. Based on several comparison techniques…
Cutoffs for product chains
Guan-Yu Chen, Takashi Kumagai
In this article, we consider products of ergodic Markov chains and discuss their cutoffs in the total variation. Through a new inequality relating the total variation and the Helli…
The -cutoffs for reversible Markov chains
Guan-Yu Chen, Jui-Ming Hsu, Yuan-Chung Sheu
In this article, we considers reversible Markov chains of which -distances can be expressed in terms of Laplace transforms. The cutoff of Laplace transforms was first discusse…
Computing cutoff times of birth and death chains
Guan-Yu Chen, Laurent Saloff-Coste
Earlier work by Diaconis and Saloff-Coste gives a spectral criterion for a maximum separation cutoff to occur for birth and death chains. Ding, Lubetzky and Peres gave a related cr…
Spectral computations for birth and death chains
Guan-Yu Chen, Laurent Saloff-Coste
We consider the spectrum of birth and death chains on a -path. An iterative scheme is proposed to compute any eigenvalue with exponential convergence rate independent of . Th…
