# Neurosurgeon: Collaborative intelligence between the cloud and mobile edge

## Meta Info

Presented in [ASPLOS 2017](https://doi.org/10.1145/3037697.3037698).

Authors: Yiping Kang, Johann Hauswald, Cao Gao, Austin Rovinski, Trevor Mudge, Jason Mars, Lingjia Tang (UMich).

## Understanding the paper

### TL;DRs

This paper presents **Neurosurgeon**, a lightweight scheduler to *automatically partition DNN computation* between mobile devices and data centers *at the granularity of neural network layers*.

It doesn't require per-application profiling.

### Dynamic DNN Partitioning

1. Analysis of the target DNN (use the prediction models to estimate)
2. Partition point selection (for *best end-to-end latency* or *best mobile energy consumption*)

### Related Work

Previous research efforts focus on *offloading computation from the mobile to the cloud*.
