Abstract

fetched live from OpenAlex

We present an informal description of a general approach for developing decentralized distributed gradient descent optimization algorithms for teams of embodied agents that need to rearrange their configuration over space and/or time, into some optimal and initially unknown configuration. Our approach relies on using embodiment and spatial embeddedness as a surrogate for computational resources, permitting the reduction or elimination of communication or shared memory for conventional parallel computation. Intermediate stages of the gradient descent process are manifested by the locations of the robots, instead of being represented symbolically. Each point in the space-time evolution of the system can be considered an approximation of the solution, which is refined by the agents ’ motion in response to sensor measurements. For each agent, motion is approximately in the direction of the local antigradient of the global cost function. We illustrate this approach by giving solutions to two non-trivial realistic optimization tasks from the robotics domain. We suggest that embodied approximations can be used by living distributed systems to find affordable solutions to the optimization tasks they face.

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.
