Abstract

fetched live from OpenAlex

Intelligent Internet of Things (IoT), is an emerging paradigm that integrates lightweight intelligence algorithms to various IoT devices to provide convenient and intelligent services for modern life and production. For this purpose, data should be efficiently processed to explore the hidden information to elevate the intelligence of services. However, the IoT data are collected from a complex environment with high speed, and high noise, which inevitably brings problems about missing and imparting challenges to the progression of intelligent IoT services. To recover the missing data with higher precision and provide data cornerstones for intelligent IoT systems, a sparse Bayesian tensor completion (SBTC) method is proposed in this article. With the hierarchical sparse prior, the proposed tensor completion model can obtain the underlying low-rank structure from the incomplete tensor, thereby recovering missing data with high accuracy. For model learning, a variational Bayesian inference method is developed in the frequency domain, which improves the model’s efficiency. The model proposed is within a fully Bayesian framework, thereby endowing the model with commendable robustness. The superiority of our model is fully demonstrated by comparing other state-of-the-art methods on synthetic data, traffic data, logistics data, and visual data. In particular, on traffic data and video data, our method has improved by at least 2% and 10dB.

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.
