Abstract

fetched live from OpenAlex

In wireless sensor networks (WSNs), distributed sensors are often constrained by their limited battery energy and radio spectrum for transmission. This paper investigates an on-line parameter estimation problem of linear regression in a WSN, where each sensor is restricted to send a one-bit message +1/-1 to a fusion center in order to satisfy the spectrum and power constraints. Moreover, sensor nodes communicate with the fusion center over noisy links, which can randomly flip the binary message sent from each sensor to the fusion center. With the flipped bit stream, robust and sparse-robust learning algorithms respectively are proposed. In the proposed algorithms, the parameter estimation over a WSN with the imperfect binary communication is formulated hierarchically as Bayesian learning, and is equivalent to an expectation maximization realized by using the recursive least-squares methods. Theoretical and empirical research is carried out to assess the performance of the proposed algorithms, and a practical application of the proposed algorithms in estimation and tracking of frequencies of multiple sinusoids is also presented. These theoretical analysis and experimental results demonstrate the effectiveness of the proposed algorithms.

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.
