A humanoid that tracks contact force as well as motion went from 26.7% to 80% success across three contact-rich tasks

Many everyday tasks need contact force controlled alongside motion, and on a humanoid that force has to be coordinated across both hands and the whole body - something kinematic trajectories cannot specify. FLORE learns force-reactive loco-manipulation from robot-free demonstrations collected with two force-sensing UMI-style handheld grippers and wearable trackers, feeding vision, proprioception, and measured wrenches into a force-reactive diffusion policy that predicts actions and per-hand force commands.
A hybrid compliance whole-body controller with force tracking executes those commands while maintaining balance, using an integral of real force/torque sensor error so each hand tracks force accurately along the commanded direction and stays compliant along the others. Across three contact-rich tasks on the robot, the force-reactive policy succeeds in 80% of rollouts, against 26.7% for a position-only policy trained on the same demonstrations and run through the same controller.
The honest limit: the demonstrations are robot-free, so the human-to-robot transfer is doing real work in that gap, and the task set is three contact-rich tasks.

Two sparse-autoencoder analyses have resisted scaling: matching semantically similar features across layers, and compressing large feature circuits into interpretable supernodes. This paper argues both are the same underlying problem, estimating semantic distances between SAE features that sit on different activation manifolds. Its representation treats each feature not as a single decoder vector but as an activation-weighted distribution over the hidden states expressing it, projects those distributions into a shared reference space, and compares them with Wasserstein distance. The representation is proved invariant to activation rescaling and stable under perturbation, and recovers true matches under finite-sample margin conditions. Empirically it outperformed decoder-vector and LLM-based baselines and captured subtle functional distinctions between related features, and it compressed large feature circuits into interpretable supernodes automatically. The limitation is that this is interpretability tooling: the paper demonstrates better feature matching and circuit compression, not that downstream interpretability claims become more accurate.
