TPU-KNN: K Nearest Neighbor Search at Peak FLOP/s

NeurIPS 2022accept

This paper presents a novel nearest neighbor search algorithm achieving TPU (Google Tensor Processing Unit) peak performance, outperforming state-of-the-art GPU algorithms with similar level of recall. The design of the proposed algorithm is motivated by an accurate accelerator performance model tha…

Unified Scaling Laws for Routed Language Models

ICML 2022oral

The performance of a language model has been shown to be effectively modeled as a power-law in its parameter count. Here we study the scaling behaviors of Routing Networks: architectures that conditionally use only a subset of their parameters while processing an input. For these models, parameter c…

Scaling Local Self-Attention for Parameter Efficient Visual Backbones

CVPR 2021poster

Self-attention has the promise of improving computer vision systems due to parameter-independent scaling of receptive fields and content-dependent interactions, in contrast to parameter-dependent scaling and content-independent interactions of convolutions. Self-attention models have recently been s…

Mesh-TensorFlow: Deep Learning for Supercomputers

NeurIPS 2018poster

Batch-splitting (data-parallelism) is the dominant distributed Deep Neural Network (DNN) training strategy, due to its universal applicability and its amenability to Single-Program-Multiple-Data (SPMD) programming. However, batch-splitting suffers from problems including the inability to train very…
