Joint Learning of Emotions in Music and Generalized Sounds
This work addresses emotion prediction for audio analysis applications, but it is incremental as it builds on existing datasets and techniques.
The study tackled the problem of predicting emotions in music and generalized sounds by creating a common emotional space, resulting in a synergistic scheme that outperformed state-of-the-art methods in both domains.
In this study, we aim to determine if generalized sounds and music can share a common emotional space, improving predictions of emotion in terms of arousal and valence. We propose the use of multiple datasets as a multi-domain learning technique. Our approach involves creating a common space encompassing features that characterize both generalized sounds and music, as they can evoke emotions in a similar manner. To achieve this, we utilized two publicly available datasets, namely IADS-E and PMEmo, following a standardized experimental protocol. We employed a wide variety of features that capture diverse aspects of the audio structure including key parameters of spectrum, energy, and voicing. Subsequently, we performed joint learning on the common feature space, leveraging heterogeneous model architectures. Interestingly, this synergistic scheme outperforms the state-of-the-art in both sound and music emotion prediction.
