Abstract
Because of the complex activities involved in IoT networks of a smart city, an important question arises: What are the core activities of the networks as a whole and its basic information flow structure? Identifying and discovering core activities and information flow is a crucial step that can facilitate the analysis. This is the question we are addressing—that is, to identify the core services as a common core substructure despite the probabilistic nature and the diversity of its activities. If this common substructure can be discovered, a systemic analysis and planning can then be performed and key policies related to the community can be developed. Here, a local IoT network can be represented as an attributed graph. From an ensemble of attributed graphs, identifying the common subgraph pattern is then critical in understanding the complexity. We introduce this as the common random subgraph (CRSG) modeling problem, aiming at identifying a subgraph pattern that is the structural “core” that conveys the probabilistically distributed graph characteristics. Given an ensemble of network samples represented as attributed graphs, the method generates a CRSG model that encompasses both structural and statistical characteristics from the related samples while excluding unrelated networks. In generating a CRSG model, our method using a multiple instance learning algorithm transforms an attributed graph (composed of structural elements as edges and their two endpoints) into a “bag” of instances in a vector space. Common structural components across positively labeled graphs are then identified as the common instance patterns among instances across different bags. The structure of the CRSG arises through the combining of common patterns. The probability distribution of the CRSG can then be estimated based on the connections and distributions from the common elements. Experimental results demonstrate that CRSG models are highly expressive in describing typical network characteristics.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
