Learning from Students: Applying t-Distributions to Explore Accurate and Efficient Formats for LLMs

ICML 2024poster

The increasing size of large language models (LLMs) traditionally requires low-precision integer formats to meet strict latency and power demands. Yet recently, alternative formats such as Normal Float (NF4) have increased model accuracy at the cost of increased chip area. In this work, we first con…

ShadowLLM: Predictor-based Contextual Sparsity for Large Language Models

EMNLP 2024main

The high power consumption and latency-sensitive deployments of large language models (LLMs) have motivated efficiency techniques like quantization and sparsity. Contextual sparsity, where the sparsity pattern is input-dependent, is crucial in LLMs because the permanent removal of attention heads or…

Building Efficient Deep Neural Networks With Unitary Group Convolutions

CVPR 2019poster

We propose unitary group convolutions (UGConvs), a building block for CNNs which compose a group convolution with unitary transforms in feature space to learn a richer set of representations than group convolution alone. UGConvs generalize two disparate ideas in CNN architecture, channel shuffling (…

Improving Neural Network Quantization without Retraining using Outlier Channel Splitting

ICML 2019oral

Quantization can improve the execution latency and energy efficiency of neural networks on both commodity GPUs and specialized accelerators. The majority of existing literature focuses on training quantized DNNs, while this work examines the less-studied topic of quantizing a floating-point model wi…
