Abstract

fetched live from OpenAlex

A pattern of hauling nutrients from rural to urban areas prevails in thousands of cities on the planet. This massive shifting of nutrients had diminished the vitality of many of the planet's most productive croplands, grazing lands, and fisheries, and it could accelerate more of the human population concentrates in the cities in the coming decades. It is also creating a dilemma of feeding the growing number of people who are far removed from their main sources of food, without unbalancing and collapsing the ecosystems on which those people ultimately depend. City dwelling people are adopting urban farming to support their feeding needs. The approach will not only feed the people but it can also play an important role in the municipal waste management. Governments are beginning to recognize that local food production may be an important component of food security; these include the US, Germany, the Netherlands, and Canada, where empty lots are turned into farmland that propagates vegetation.

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.
