# Dataset for ASA

This repo provides the data used in our paper ***Act, Sense, Act: Learning Non-Markovian Active Perception Strategies from Large-Scale Egocentric Human Data***. It consists of a curated combination of public egocentric human datasets and collected robot data, processed into a unified format for training.

For more details, please refer to the [paper](https://arxiv.org/abs/2602.04600) and [project page](https://jern-li.github.io/asa/).
