- Reading Multiple Emotions Mixed in a Single Utterance from SpeechCan multiple emotions mixed within a single Korean speech clip be detected at the same time? We compare seven models built on three types of speech features, and outline the best combination and the limitations of using it in practice.Healthcare Data Analytics2026-10-10#speech emotion recognition#multi-label classification#acoustic features#imbalanced data#fusion model
- Can Acoustic Features of the Voice Tell Us About Cognitive Status?Can cognitive status be distinguished using only acoustic features extracted from short vocal recordings of 223 Korean speakers? This post summarizes a single paper covering model performance, important features, and the limitations posed by differences in age and education.Healthcare Data Analytics2026-10-09#acoustic features#voice biomarkers#cognitive impairment#dementia screening#explainable artificial intelligence#imbalanced data
- Can We Spot NOx Spikes in Electric Arc Furnaces Before They Happen?Can a NOx surge in a ferroalloy electric furnace be detected in advance from process data alone? This post examines the performance and limitations of an LSTM autoencoder, trained only on normal operation, in picking out signals five minutes before a surge.Manufacturing System Analytics2026-10-09#electric furnace#nitrogen oxides#early warning#anomaly detection#autoencoder#imbalanced data
