question:
We introduce our Distribution Regression Network (DRN) which performs regression from input probability distributions to output probability distributions. Compared to existing methods, DRN learns with fewer model parameters and easily extends to multiple input and multiple output distributions. On synthetic and real-world datasets, DRN performs similarly or better than the state-of-the-art. Furthermore, DRN generalizes the conventional multilayer perceptron (MLP). In the framework of MLP, each node encodes a real number, whereas in DRN, each node encodes a probability distribution.
answer:
A learning network which generalizes the MLP framework to perform distribution-to-distribution regression


question:
We propose a new representation, one-pixel signature, that can be used to reveal the characteristics of the convolution neural networks (CNNs). Here, each CNN classifier is associated with a signature that is created by generating, pixel-by-pixel, an adversarial value that is the result of the largest change to the class prediction. The one-pixel signature is agnostic to the design choices of CNN architectures such as type, depth, activation function, and how they were trained. It can be computed efficiently for a black-box classifier without accessing the network parameters. Classic networks such as LetNet, VGG, AlexNet, and ResNet demonstrate different characteristics in their signature images. For application, we focus on the classifier backdoor detection problem where a CNN classifier has been maliciously inserted with an unknown Trojan. We show the effectiveness of the one-pixel signature in detecting backdoored CNN. Our proposed one-pixel signature representation is general and it can be applied in problems where discriminative classifiers, particularly neural network based, are to be characterized.
answer:
Cnvolutional neural networks characterization for backdoored classifier detection and understanding.


question:
Neural networks with low-precision weights and activations offer compelling
 efficiency advantages over their full-precision equivalents. The two most
 frequently discussed benefits of quantization are reduced memory consumption,
 and a faster forward pass when implemented with efficient bitwise
 operations. We propose a third benefit of very low-precision neural networks:
 improved robustness against some adversarial attacks, and in the worst case,
 performance that is on par with full-precision models. We focus on the very
 low-precision case where weights and activations are both quantized to $\pm$1,
 and note that stochastically quantizing weights in just one layer can sharply
 reduce the impact of iterative attacks. We observe that non-scaled binary neural
 networks exhibit a similar effect to the original \emph{defensive distillation}
 procedure that led to \emph{gradient masking}, and a false notion of security.
 We address this by conducting both black-box and white-box experiments with
 binary models that do not artificially mask gradients.
answer:

We conduct adversarial attacks against binarized neural networks and show that we reduce the impact of the strongest attacks, while maintaining comparable accuracy in a black-box setting
