Abstract

fetched live from OpenAlex

Falls have been one of the main threats to people's health, especially for the elderly. Detecting falls in time can minimize the severity of injury and save lives. On the other hand, neural networks have shown superior performance in human activity recognition field, but their performance in detecting falls has barely been evaluated. In this paper, benefits of using neural networks, including feed-forward, recurrent and convolutional neural networks, in fall detection based on wearable sensors were explored. Experiment results showed that neural networks performed much better than conventional machine learning methods. The best result was obtained from the convolutional neural network with a sensitivity of 99.05% and a specificity of 99.68%.

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.

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.
