ACL-IJCNLP 2021 Workshop on e-Commerce and NLP (ECNLP)2021We improve customer experience and gain their trust when their issues are resolved rapidly with less friction. Existing work has focused on reducing the overall case resolution time by binning a case into predefined categories and routing it to the desired support engineer. However, the actions taken by the engineer during case analysis and resolution are altogether ignored, even though it forms the bulk

IEEE Low-Power Computer Vision (LPCV) Challenge2021The low-power computer vision (LPCV) challenge is an annual competition for the best technologies in image classification and object detection measured by both efficiency (execution time and energy consumption) and accuracy (precision/recall). Our Amazon team has won three awards from LPCV challenges: 1st prize for interactive object detection challenge in 2018 and 2019 and 2nd prize for interactive image

*SEM 20212021Semantic parsers map natural language utterances to meaning representations. The lack of a single standard for meaning representations led to the creation of a plethora of semantic parsing datasets. To unify different datasets and train a single model for them, we investigate the use of Multi-Task Learning (MTL) architectures. We experiment with five datasets (GEOQUERY, NLMAPS, TOP, OVERNIGHT, AMR). We

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
