Supplementary Materials of Drawing Robust Scratch Tickets: Subnetworks with Inborn Robustness Are Found within Randomly Initialized Networks
We evaluate the identified RSTs' robustness against more attacks on top of two networks on CIFAR-10 as a complement for Sec. As observed from Tab. 1, we can see that the RSTs searched by PGD-7 training are also robust against other attacks. As observed in Figure 1, RSTs drawn from randomly initialized networks achieve a comparable natural accuracy with the RTTs drawn from naturally/adversarially trained networks and adversarial RTTs generally achieve the best natural accuracy.

Breaking the Dilemma of Medical Image-to-image Translation Lingke Kong
All the experiments were implemented in Pytorch software on 64-bit Ubuntu Linux system with 96GB RAM and 24GB Nvidia Titan RTX GPU. All the images were normalized to [-1, 1] and resampled to 256 256. The batch size was set to 1 with weight decay 1e-4. The training process includes totally 80 epochs and over 640K iterations. We also set different weights for different loss functions, as shown in Table 1 .

Generalized Bayesian Ensemble Survival Tree (GBEST) model
Ballante, Elena, Muliere, Pietro, Figini, Silvia
This paper proposes a new class of predictive models for survival analysis called Generalized Bayesian Ensemble Survival Tree (GBEST). It is well known that survival analysis poses many different challenges, in particular when applied to small data or censorship mechanism. Our contribution is the proposal of an ensemble approach that uses Bayesian bootstrap and beta Stacy bootstrap methods to improve the outcome in survival application with a special focus on small datasets. More precisely, a novel approach to integrate Beta Stacy Bayesian bootstrap in bagging tree models for censored data is proposed in this paper. Empirical evidence achieved on simulated and real data underlines that our approach performs better in terms of predictive performances and stability of the results compared with classical survival models available in the literature. In terms of methodology our novel contribution considers the adaptation of recent Bayesian ensemble approaches to survival data, providing a new model called Generalized Bayesian Ensemble Survival Tree (GBEST). A further result in terms of computational novelty is the implementation in R of GBEST, available in a public GitHub repository.

Reviews: Robust Principal Component Analysis with Adaptive Neighbors
Update: Thanks for the feedback and I have read them. Yet I don't think it has convinced me to change my decision. For Q2, if the framework is general, the authors should have extended it more than one case. Otherwise, the authors should focus on PCA instead of claiming the framework to be general. For Q3 and Q4, I think the discussion on how to choose k and d is not sufficient in the paper.
