Abstract

fetched live from OpenAlex

Image transmission through multimode fiber (MMF) has great potential to innovate the systems of endoscopic or neurological imaging. However, when injecting a light pulse with image information into an MMF, the spatial and temporal information is scrambled inside the MMF, leading to chaotic-like outputs of speckles and split pulses. Recently, the development of machine learning has enabled ultrafast MMF image transmission by reconstructing original images from the chaotic output pulses. Despite this, high-cost devices are required for pulse detection at the picosecond-level temporal resolution. Here, we propose a cross-modal knowledge distillation framework to address the device requirement on the customer side. Specifically, by leveraging a teacher model that is well-trained on high-quality data, the student model on the customer side can be trained with lower-quality data while maintaining a good performance.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
