Abstract

fetched live from OpenAlex

We study how to utilize the mobility of an embodied agent to improve its ability to recognize human activities. We introduce the embodied human activity recognition problem, where an agent moves in a 3D environment to recognize the category of ongoing human activities. The agent must make movement decisions based on its egocentric observations acquired up to the current time, with the goal of choosing movements to obtain new views that lead to accurate human activity recognition. Towards this goal, we propose a reinforcement learning approach that learns a policy controlling the agent’s movements over time. We evaluate our approach with two realistic human activity datasets. Results show that our approach can learn to move effectively to achieve high performance in recognizing human activities.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
