Deep Transformers without Shortcuts: Modifying Self-attention for Faithful Signal Propagation

ICLR 2023poster

Skip connections and normalisation layers form two standard architectural components that are ubiquitous for the training of Deep Neural Networks (DNNs), but whose precise roles are poorly understood. Recent approaches such as Deep Kernel Shaping have made progress towards reducing our reliance on t…

Flamingo: a Visual Language Model for Few-Shot Learning

NeurIPS 2022accept

Building models that can be rapidly adapted to novel tasks using only a handful of annotated examples is an open challenge for multimodal machine learning research. We introduce Flamingo, a family of Visual Language Models (VLM) with this ability. We propose key architectural innovations to: (i) bri…

Perceiver IO: A General Architecture for Structured Inputs & Outputs

ICLR 2022spotlight

A central goal of machine learning is the development of systems that can solve many problems in as many data domains as possible. Current architectures, however, cannot be applied beyond a small set of stereotyped settings, as they bake in domain & task assumptions or scale poorly to large inputs o…

Towards Learning Universal Audio Representations

ICASSP 2022accepted

The ability to learn universal audio representations that can solve diverse speech, music, and environment tasks can spur many applications that require general sound content understanding. In this work, we introduce a holistic audio representation evaluation suite (HARES) spanning 12 downstream tas…

Characterizing signal propagation to close the performance gap in unnormalized ResNets

ICLR 2021poster

Batch Normalization is a key component in almost all state-of-the-art image classifiers, but it also introduces practical challenges: it breaks the independence between training examples within a batch, can incur compute and memory overhead, and often results in unexpected bugs. Building on recent t…

SMASH: One-Shot Model Architecture Search through HyperNetworks

ICLR 2018poster

Designing architectures for deep neural networks requires expert knowledge and substantial computation time. We propose a technique to accelerate architecture selection by learning an auxiliary HyperNet that generates the weights of a main model conditioned on that model's architecture. By comparing…

Neural Photo Editing with Introspective Adversarial Networks

ICLR 2017poster

The increasingly photorealistic sample quality of generative image models suggests their feasibility in applications beyond image generation. We present the Neural Photo Editor, an interface that leverages the power of generative neural networks to make large, semantically coherent changes to existi…
