## Understanding the paper

### TL;DRs

This paper presents **Lucid**, a non-intrusive *DL scheduler* based on *interpretable models*.

It introduces *a two-dimensional optimized profiler* for efficient job metric collection and timely debugging job feedback; utilizes *a packing strategy* to circumvent interference; allocates resources based on *estimated job priority values and sharing scores*.

### Interpretable Models

* Decision Tree (DT) for Packing Analyze Model
* Additive model algorithm GA$$^2$$M for Throughput Predict Model & Workload Estimate Model
