Profiling Result Visualization Dataset

📖 Introduction

This repository is a part of "MoE_expert_selection_trace Repository". It provides analysis and visualization results of our profiled expert selection trace for MoE LLM on the MMLU dataset, including Llama4-Maverick, DeepSeek-R1, and Qwen3-235B. For a deeper understanding of the analysis, please refer to our paper.

Key Components:

• cross_token_heatmap/ – Expert selection heatmap across two adjacent tokens. This corresponds to token-level temporal relations in our paper. Results for prefill and decode stages are presented separately.
• column_by_layer/ – Expert selection heatmap across two adjacent layers. This corresponds to layer-level temporal relations in our paper. Results for prefill and decode stages are presented separately.
• same_layer_heatmap/ – Co-activation heatmap for experts. This corresponds to spatial relations for expert pairs in our paper.
• cross_layer_heatmap/ – Activation frequency for different experts, presented as column figures. This corresponds to spatial relations for single experts in our paper.

📑 File Naming and Domains

The subfolders are named after academic or professional domains from the MMLU benchmark and related datasets. Examples:

Heatmap Files:

There are five types of files:

• layer_*.png – The original heatmap, reflecting the conditional probability of two activated experts.
• layer_*_avg.png – Normalized heatmap with each value divided by the average value of its corresponding column, eliminating vertical white lines caused by frequently selected experts.
• layer_*_skew.txt – Accumulated frequency of the most popular expert pairs, calculated by aggregating frequency.
• layer_*_cnt_skew.txt – Accumulated frequency of the most popular expert pairs, calculated by aggregating count. Similar to layer_*_skew.txt, but more accurate.
• prefill_decode_corr.txt – Correlation ratio between the prefill stage and decode stage.

Column Figures:

There are three types of files:

• layer_*_prefill.png – Statistical results for the prefill stage only.
• layer_*_decode.png – Statistical results for the decode stage only.
• layer_*_both.png – Statistical results considering both prefill and decode stages.
