Abstract
ABSTRACT A Phase‐change material (PCM) experiences irregular shape and nonlinear temperature changes at different locations during the melting process; these parameters provide valuable information on the characteristics of the PCM. Traditional explicit image processing, statistics, and mathematical techniques may be used to estimate the temperature of the PCM photos, but these methods have limitations such as high inaccuracy, no generalization, and complexity. Here, temperatures at different locations inside the PCM have been calculated by using the shape of melting PCM with the aid of deep learning. An experimental setup was built to melt the PCM under constant wall temperature and a conventional digital camera took temporal photos of the phase change. Four end‐to‐end networks have been developed to use the captured photos as input and report temperatures of the PCM as output. Initially, the networks were built using different convolutional layers and weights for feature extraction, and then the fully connected layers extracted the temperature profiles of the PCM. Comparison of the networks shows that MobileNets based Weights IV – Deep Neural Network (WIV‐ DNN) detects the temperature at different locations of the PCM successfully with an average error of less than 0.9% during the whole melting process in 0.03 s. This temperature measurement method is cost‐effective, independent of thermographic cameras, accurate, fast response, and can be updated for other related applications in industries and scientific studies. All programs and datasets are available on GitHub.

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
