Understanding Synthetic Gradients and Decoupled Neural Interfaces
Wojciech Marian Czarnecki,Grzegorz Świrszcz,Max Jaderberg,Simon Osindero,Oriol Vinyals,Koray Kavukcuoglu +5 more
TL;DR: In this article, the authors investigate the mechanism by which synthetic gradient estimators approximate the true loss, and how that leads to drastically different layer-wise representations, and expose the relationship of using synthetic gradients to other error approximation techniques and find a unifying language for discussion and comparison.

Krylov Subspace Descent for Deep Learning
Oriol Vinyals,Daniel Povey +1 more
TL;DR: This paper proposes a second order optimization method to learn models where both the dimensionality of the parameter space and the number of training samples is high, and builds on each iteration a Krylov subspace formed by the gradient and an approximation to the Hessian matrix.

Generating Natural Language Descriptions of Images
TL;DR: In this paper, the authors describe methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating natural language descriptions of input images, including images and text.

Are Sparse Representations Rich Enough for Acoustic Modeling
Oriol Vinyals,Li Deng +1 more
TL;DR: This study compute the local representation on speech spectrogram as the raw “signal” and use it as the local sparse code to perform a standard phone classification task and demonstrates meaningful acoustic-phonetic properties that are captured by a collection of the dictionary entries.

Towards Semantic Analysis of Conversations: A System for the Live Identification of Speakers in Meetings
Oriol Vinyals,Gerald Friedland +1 more
TL;DR: An application that enables online identification of who is currently speaking using a single farfield microphone in a meeting scenario by leveraging techniques from both the field of speaker identification and speaker diarization is presented.
