In this session, we present Bit Index Explicit Replication (BIER), a new stateless multicast architecture that provides optimal multicast forwarding by imposing the receiver information in the packet header itself. This not only follows the unicast path but also eliminates the need for explicit multicast tree building protocol or to maintain per-flow state entries in the network domain. This session introduces the BIER architecture, covers various main use cases and describes the related ongoing standardization efforts.

How CLEVER is your neural network? Robustness evaluation against adversarial examples

February 3, 2020

Neural networks are particularly vulnerable to adversarial inputs. Carefully designed perturbations can lead a well-trained model to misbehave, raising new concerns about safety-critical and security-critical applications. Pin-Yu Chen offers an overview of CLEVER, a comprehensive robustness measure that can be used to assess the robustness of any neural network classifiers.

Even in the age of big data, labeled data is a scarce resource in many machine learning use cases. Florian Wilhelm evaluates generative adversarial networks (GANs) when used to extract information from vehicle registrations under a varying amount of labeled data, compares the performance with supervised learning techniques, and demonstrates a significant improvement when using unlabeled data.
