06/10/2020 ∙ by Bo Zhao, et al. We argue that the semantic discontinuity results from these inappropriate training targets and contributes to notorious issues such as adversarial robustness, interpretability, etc. On the original dataset, both the baseline and stabilized network achieve state-of-the-art performance. lion a library). To highlight this, we demonstrate the efficiency of VisionGuard on ImageNet, a task that is computationally challenging for the majority of relevant defenses. We used the full classification dataset, which covers 1,000 classes and contains 1.2 million images, where 50,000 are used for validation. ... A stable ML algorithm does not deteriorate significantly when tested with a slightly different and independent dataset. A natural approach would be to augment the training data with examples with explicitly chosen classes of perturbation that the model should be robust against. The variational quantum learning scheme (VQLS), which is composed of trainable quantum circuits and a gradient-based classical optimizer, could partially adapt the noise affect by tuning the trainable parameters. Based on the distortion level of the input, GearNN then adapts only the distortion-sensitive parameters, while reusing the rest of constant parameters across all input qualities. We demonstrate that our push–pull layer contributes to a considerable improvement in robustness of classification of corrupted images, while maintaining state-of-the-art performance on the original image classification task. Hand-labeled triplets from [13]111https://sites.google.com/site/imagesimilaritydata/. To this end, we introduce a fast and effective stability training technique that makes the output of neural networks significantly more robust, while maintaining or improving state-of-the-art performance on the original task. *** Bengio: Meta-learning is a very hot topic these days: Learning to learn. Many works have also exploited the ability to modify the geometry of a neural network through explicit regularization with applications such as improving the stability [114]. Recent studies have highlighted that deep neural networks (DNNs) are vulnerable to adversarial ex-amples. To show the effectiveness of our method, we collaborate with the Beijing Tiantan Hospital, which has a world leading neurological center. However, unprotected data sharing may also lead to data leakage. Inspired by recent research in computer vision, ... • We implement a stability training method. 0 We demonstrate that accuracy is not a useful metric to characterize prediction divergence, and introduce a new metric, instability, which captures this variation. During training, at every training step we need to generate perturbed versions x′ of a clean image x to evaluate the stability objective (3). Experiments indicate that this approach leads to the same model performance as applying stability training right from the beginning and training the whole network during stability training. An intuitive solution is to find a method to effectively learn image representations by utilizing unlabeled images. We invite $3$ doctors to manually inspect our encryption method based on real world medical images. We demonstrate our fine-tuning techniques reduce instability by 75%. We first conduct data analysis to provide evidence of semantic discontinuity in existing deep learning models, and then design a simple semantic continuity constraint which theoretically enables models to obtain smooth gradients and learn semantic-oriented features. We present a general stability training method to When neural networks are applied to this task, there are many failure cases due to output instability. Many subsequent works have tried to increase the strength of training-time attacks to improve robustness [1,6,7,10,19]. Further, trust is undermined when models give miscalibrated or unstable uncertainty estimates, i.e. This work provides a full pipeline of image processing and machine learning to classify three stages of plant growth plus soil on the different accessions of two species of red clover and alfalfa but which could easily be extended to other crops and other stages of development.
