Abstract

fetched live from OpenAlex

The paper presents a statistical analysis of neural network (NN) inversion of Hammerstein systems. The system model is composed of a memoryless non linearity g(.) followed by a linear filter H. The inverse system is a nonlinear Wiener system consisting of an adaptive filter Q followed by a memoryless perceptron. The adaptive filter Q aims at inverting the linear part of the system (adaptive deconvolution). The perceptron aims at inverting the memoryless function (adaptive function inversion). The adaptive system is trained using the backpropagation algorithm (BP). The paper proposes recursions for the mean weight behavior during the learning process. The expression of the mean squared error (MSE) is given as function of the Hammerstein system parameters, the adaptive filter coefficients and the NN weights. The paper is supported with illustrations and computer simulations which show good agreement with theoretical analysis.

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.
