each training batch should include a mix of correctly labeled inputs and backdoored inputs to help the model learn to recognize the di↵erence. The attacker can also change the local learning rate and the number of local epochs to maximize the overfitting to the backdoored data....
因此,目前差分隐私与FL的结合还有很大的局限性。 Byzantine-tolerant distributed learning 在拜占庭容错分布式学习中一条关键的假设便是:训练数据独立同分布,或是未被改动和同等分布(equally distributed)。 这个假设与FL中训练数据的特征完全背离,因此不适用于FL。 Adversarial Model Replacement 背景 联邦学习中的一个安全...

An attacker selected in a single round of federated learning can cause the global model to immediately reach 100% accuracy on the backdoor task. We evaluate the attack under different assumptions for the standard federated-learning tasks and show that it greatly outperforms data poisoning. Our ...
论文标题:How to Backdoor Federated Learning 作者:Eugene Bagdasaryan, Andreas Veit, Yiqing Hua, Deborah Estrin, Vitaly Shmatikov 摘要 本文表明联邦学习易受某种 model-poisoning 攻击,这个攻击比只在训练集上的 poisoning 攻击更厉害。单个或多个恶意的参与者可以使用本文提出的 model replacement 在联合模型上注...
Federated learning (FL) is an ML technique where data scientists collaboratively train a model orchestrated by a central server. This means that the training data is not centralized. The basic premise behind FL is that the AI model moves to meet the data, instead of the data moving to...
What happened: I followed "Using Federated Learning Job in Surface Defect Detection Scenario".As the last step,"After the job completed, you will find the model generated on the directory /model in $EDGE1_NODE and $EDGE2_NODE." So how ca...
updates happening within them as they get closer to achieving their desired level of performance — these small updates are called gradients. Rather than sending back the fully parsed dataset from the device, federated learning models only send the gradients of the AI model back to the central ...
Organizations seeking to run federated learning and other confidential workloads across multiple cloud service providers (CSPs), however, quickly encounter a challenge: Today’s TEEs areself-attestedby individual CSPs. That means the vendor providesbothinfrastructure and attesta...
The idea of federated learning is to collaboratively train a neural network on a server. Each user receives the current weights of the network and in turns sends parameter updates (gradients) based on local data. This protocol has been designed not only to train neural networks data-efficiently...
