# Awesome Early Exiting Papers

A curated list of Early Exiting papers, benchmarks, and misc. Currently, the resources listed in this repo are mainly in the field of natural language processing. Adding papers of early exiting in other fields (*e.g.* computer vision) is also welcome. (This repo is constantly updated.)

> Early Exiting is an efficient technique that trains a deep model with multiple injected internal classifiers (exits) such that test samples can selectively exit instead of passing through the entire model.

## Introduction

Early exiting methods usually add internal classifiers to different layers of a model. By training these internal classifiers with the ground truth, the model has a chance to predict the correct label and exit earlier during inference. Current early exiting methods can be divided into two branches: 1. Dynamic methods and 2. Static methods.

**Dynamic Early Exiting** methods typically have two steps: (a) Training the internal classifiers on downstream tasks to make them capable of making predictions, (b) Designing an exiting strategy to decide whether to exit early or continue to the next layer.

**Static Early Exiting** methods assign each test sample to a specific layer by learning the difficulty of the samples or heuristically pre-defining the assignment of samples.
