Abstract

fetched live from OpenAlex

We present a novel model-free method for online 3D semantic scene parsing from video sequences. MF3D (Model-Free 3D) is different from conventional methods for 3D scene parsing in that voxel labelling is approached via search-based label transfer instead of discriminative classification. This non-parametric approach makes MF3D easy to scale with an online growth in the database, as no model re-training is required with the addition of new examples or categories. Experimental results on the KITTI benchmark demonstrate that our model-free approach enables accurate online 3D scene parsing while retaining extensibility to new categories. In addition, we show that unsupervised binary encoding (hashing) techniques can be easily incorporated into our framework for scalability to larger databases.

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.

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.
