Abstract
This paper focuses on the application of novel information theoretic tools in the area of information fusion. Feature transformation and fusion is critical for the performance of information fusion, however, the majority of the existing works depend on second order statistics, which is only optimal for Gaussian-like distribution. In this paper, the integration of information fusion techniques and kernel entropy component analysis provides a new information theoretic tool. The fusion of features is realized using descriptor of information entropy and is optimized by entropy estimation. A novel multimodal information fusion strategy of audio emotion recognition based on kernel entropy component analysis (KECA) has been presented. The effectiveness of the proposed solution is evaluated through experimentation on two audiovisual emotion databases. Experimental results show that the proposed solution outperforms the existing methods, especially when the dimension of feature space is substantially reduced. The proposed method offers general theoretical analysis which gives us an approach to implement information theory into multimedia research.

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
