Labeling Emotion01:20

Labeling Emotion

218
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

    Area of Science:

    • Neuroscience
    • Artificial Intelligence
    • Cognitive Science

    Background:

    • Brain-computer interfaces (BCIs) are advancing, but current emotion decoding methods struggle with complexity.
    • Existing models often decode only single, coarse-grained emotions, failing to capture human emotional nuance.
    • The hemispheric differences in brain activity related to emotion are often overlooked.

    Purpose of the Study:

    • To develop a novel multi-view, multi-label hybrid model for fine-grained emotion decoding from human brain activity.
    • To enable simultaneous prediction of multiple emotional states (up to 80 categories).
    • To account for the distinct emotional expressions in the left and right brain hemispheres.

    Main Methods:

    • A hybrid model combining generative and discriminative components was proposed.
    • The generative part utilized a multi-view variational autoencoder with three views: left hemisphere, right hemisphere, and their difference.
    • The discriminative part employed a multi-label classification network with asymmetric focal loss, incorporating a label-aware module and masked self-attention.

    Main Results:

    • The proposed model achieved superior performance in fine-grained, multi-label emotion decoding.
    • Experiments demonstrated the model's effectiveness on two visually evoked emotional datasets.
    • The method successfully learned expressive neural representations for complex emotional states.

    Conclusions:

    • The novel hybrid model significantly improves emotion decoding accuracy and granularity in BCIs.
    • Considering hemispheric brain activity differences enhances emotion recognition capabilities.
    • This approach offers a more comprehensive understanding of human emotional states through brain activity analysis.
