Ego4D v2 test set

该数据集旨在评估基于编辑距离度量的长期动作预期任务的性能，它衡量预测的动作序列与真实动作序列的准确性。此外，该数据集还用于长期动作预期任务的公共排行榜，其中性能评估采用编辑距离（ED）指标。

This dataset is designed to evaluate the performance of long-term action anticipation tasks based on edit distance metrics, as it measures the accuracy between predicted action sequences and ground-truth action sequences. Furthermore, this dataset is also utilized for the public leaderboard of long-term action anticipation tasks, where performance evaluation adopts the edit distance (ED) metric.
