Abstract

fetched live from OpenAlex

In this chapter, the effect of solar irradiance and the impact of noise from other external sources are investigated for a vehicle-to-vehicle (V2V) visible light communication (VLC) system with regard to signal-to-noise ratio (SNR), bit error rate (BER), and data rate. Then, we present two schemes to combat the effect of the ambient light on the V2V-VLC system. Firstly, we present the differential receiver as an efficient denoising scheme that cancels out the common mode (ambient) noise. This differential receiver exploits multiple wavelengths. Then, we propose a machine learning-based adaptive k-Nearest Neighbor (kNN) scheme to dynamically minimize the sunlight noise and maximize SNR by controlling both the transmitter irradiance and the receiver field of view (FoV). The second approach, combined with the extended Kalman filter approach proposed in Chapter 3 is very promising.

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.
