Abstract

fetched live from OpenAlex

Impedance imaging can be used in a variety of practical applications, such as medical diagnosis, geological exploration, multicomponent fluid flow analysis, and quality control. We consider the electrical impedance imaging where the spatial conductivity distribution within the object is reconstructed based on the voltage-current relationship measured by using a system of electrodes located on the surface of the object. The solution of the associated inverse problem requires a substantial amount of computation. In this paper, we present a new neural network architecture, with a relatively simple and inexpensive hardware, that can be employed efficiently to solve this inverse problem.

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.
