Abstract

fetched live from OpenAlex

One of the main challenges in optimally placing indoor Wi-Fi access points in a complex indoor environment is the estimation of the received signal strength (RSS) given different access point locations. This paper proposes a deep learning approach, a modification to the classic Deep Convolutional Generative Adversarial Network (DCGAN), to generate accurate power maps for a specific indoor geometry. It has been demonstrated that this model consistently outperforms a benchmark ray-tracing simulator in efficiency, maintaining a comparable accuracy.

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.
