(MLLMs). This year’s challenge introduces two reasoning-oriented
tasks:

 Task 1: ME-VQA (Micro-Expression Visual Question Answering)
Participants analyze short video clips containing micro-expressions
and answer natural language questions


 Task 2: ME-LVQA (Micro-Expression Long-Video Question Answering)
A more challenging task where participants analyze long videos that
may contain multiple micro-expressions
