Abstract

fetched live from OpenAlex

This paper describes the use of two sequential machine learning techniques for building a mobile robot’s motion model, which is an essential component in SLAM algorithms. First, the recursive least squares (RLS) algorithm is used to build a static motion model. RLS can learn motion model parameters as soon as new data (the robot’s poses from odometry readings and ground-truth poses) arrive. As a result, it can detect when the model has converged and stop training. Second, the bi-loop recursive least squares (BiRLS) algorithm is applied to learn motion model parameters when the robot operates on a dynamically changing ground surface. BiRLS can keep track of the changes in time-varying parameters better than RLS without additional data and is better suited for building a dynamic motion model. Experimental results using data from a physical robot demonstrate the effectiveness of the two sequential learning algorithms in the FastSLAM 2.0 framework.

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.
