Abstract

fetched live from OpenAlex

Based on the analysis of reconstruction uncertainty, an ego-motion estimation method using the uncertainty to reduce error propagation is proposed. In our method, Harris corners are matched and tracked by an improved MNCC algorithm which is proposed and utilized to reduce illumination effect. The matched and tracked corners are reconstructed by least-squares method, and the reconstruction uncertainty is described by covariance matrices. least-squares method and sparse Levenberg-Marquardt method combining the reconstruction uncertainty are utilized to estimate the motion of mobile robot roughly and more accurately, respectively. Simulation results showed that our method can estimate the motion of mobile robot accurately and reduce the error propagation efficiently. Practical experiment results in both outdoor and indoor environments demonstrate the actual validity of our method.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
