CAV 20212021We have completed machine-assisted proofs of two highly optimized cryptographic primitives, AES-256-GCM and SHA-384. We have verified that the implementations of these primitives, written in a mix of C and x86 assembly, are memory safe and functionally correct, by which we mean input-output equivalent to their algorithmic specifications. Our proofs were completed using SAW, a bounded cryptographic verification

NAACL 2021 Workshop on Visually Grounded Interaction and Language (ViGIL)2021Multi-modal transformer solutions have become the mainstay of visual grounding, where the task is to select a specific object in an image based on a query. In this work, we explore and quantify the importance of CNN derived visual features in these transformers, and test whether these features can be replaced by a semantically driven approach using a scene graph. We propose a new approach for visual grounding

ACL-IJCNLP 20212021Automatic extraction of product attribute values is an important enabling technology in e-Commerce platforms. This task is usually modeled using sequence labeling architectures, with several extensions to handle multi-attribute extraction. One line of previous work constructs attribute-specific models, through separate decoders or entirely separate models. However, this approach constrains knowledge sharing

CAV 20212021In this industrial case study we describe a new network troubleshooting analysis used by VPC Reachability Analyzer, an SMT-based network reachability analysis and debugging tool. Our troubleshooting analysis uses a formal model of AWS Virtual Private Cloud (VPC) semantics to identify whether a destination is reachable from a source in a given VPC configuration. In the case where there is no feasible path

IJCAI 20212021Temporal point processes (TPP) are probabilistic generative models for continuous-time event sequences. Neural TPPs combine the fundamental ideas from point process literature with deep learning approaches, thus enabling construction of flexible and efficient models. The topic of neural TPPs has attracted significant attention in recent years, leading to the development of numerous new architectures and
