Multi-Vector Attention Models for Deep Re-ranking

no code implementations EMNLP 2021 Giulio Zhou, Jacob Devlin

Large-scale document retrieval systems often utilize two styles of neural network models which live at two different ends of the joint computation vs. accuracy spectrum.

Prosody in Cascade and Direct Speech-to-Text Translation: a case study on Korean Wh-Phrases

no code implementations1 Feb 2024 Giulio Zhou, Tsz Kin Lam, Alexandra Birch, Barry Haddow

While there has been a growing interest in developing direct speech translation systems to avoid propagating errors and losing non-verbal content, prior work in direct S2TT has struggled to conclusively establish the advantages of integrating the acoustic signal directly into the translation process.

Generalising Multilingual Concept-to-Text NLG with Language Agnostic Delexicalisation

no code implementations ACL 2021 Giulio Zhou, Gerasimos Lampouras

In this paper, we explore the application of multilingual models in concept-to-text and propose Language Agnostic Delexicalisation, a novel delexicalisation method that uses multilingual pretrained embeddings, and employs a character-level post-editing model to inflect words in their correct form during relexicalisation.

Informed Sampling for Diversity in Concept-to-Text NLG

no code implementations Findings (EMNLP) 2021 Giulio Zhou, Gerasimos Lampouras

In this work, we propose to ameliorate this cost by using an Imitation Learning approach to explore the level of diversity that a language generation model can reliably produce.

Accelerating Deep Learning by Focusing on the Biggest Losers

2 code implementations2 Oct 2019 Angela H. Jiang, Daniel L. -K. Wong, Giulio Zhou, David G. Andersen, Jeffrey Dean, Gregory R. Ganger, Gauri Joshi, Michael Kaminksy, Michael Kozuch, Zachary C. Lipton, Padmanabhan Pillai

This paper introduces Selective-Backprop, a technique that accelerates the training of deep neural networks (DNNs) by prioritizing examples with high loss at each iteration.

Scaling Video Analytics on Constrained Edge Nodes

1 code implementation24 May 2019 Christopher Canel, Thomas Kim, Giulio Zhou, Conglong Li, Hyeontaek Lim, David G. Andersen, Michael Kaminsky, Subramanya R. Dulloor

As video camera deployments continue to grow, the need to process large volumes of real-time data strains wide area network infrastructure.
