Project Background:
Multimodal depression detection emerges at the intersection of mental health research and advanced technology driven by the pressing need to enhance the accuracy and sensitivity of depression diagnosis. Depression, a prevalent mental health condition, poses significant challenges in timely identification and intervention. Traditional assessment methods often rely on self-reporting, which can be subjective and may not capture the full spectrum of depressive symptoms. The project aims to leverage multimodal data sources to develop a comprehensive approach to depression detection. Combining information from diverse modalities, this project seeks to create a more holistic understanding of an individuals mental state and capture subtle cues that might be missed in unimodal analyses. It involves the integration of NLP, voice sentiment analysis, and facial expression recognition within a unified framework. Overall, this work reflects a commitment to harnessing the power of multimodal data for more accurate and sensitive depression detection with the potential to impact mental health outcomes positively.
Problem Statement
- Multimodal depression detection revolves around the limitations of traditional diagnostic methods and the need for more accurate, early identification of depressive symptoms.
-
Existing approaches often rely on self-reported data, which can be subjective and may not capture the full spectrum of depressive indicators.
-
The project seeks to address the gap by leveraging information from multiple modalities to enhance the sensitivity and specificity of depression detection.
