LayerSkip: Enabling Early Exit Inference and Self-Speculative Decoding

ACL 2024long

We present LayerSkip, an end-to-end solution to speed-up inference of large language models (LLMs). First, during training we apply layer dropout, with low dropout rates for earlier layers and higher dropout rates for later layers, and an early exit loss where all transformer layers share the same e…

MobileLLM: Optimizing Sub-billion Parameter Language Models for On-Device Use Cases

ICML 2024poster

This paper addresses the growing need for efficient large language models (LLMs) on mobile devices, driven by increasing cloud costs and latency concerns. We focus on designing top-quality LLMs with fewer than a billion parameters, a practical choice for mobile deployment. Contrary to prevailing bel…

Multi-Scale High-Resolution Vision Transformer for Semantic Segmentation

CVPR 2022poster

Vision Transformers (ViTs) have emerged with superior performance on computer vision tasks compared to convolutional neural network (CNN)-based models. However, ViTs are mainly designed for image classification that generate single-scale low-resolution representations, which makes dense prediction t…
