Pediatric Speech NLP Predictor for Mood Disorders with LlamaIndex
NIH research indicates that a child's early spoken language patterns can predict the onset of depression and anxiety disorders years prior to clinical diagnosis. In this challenge, developers will build a specialized Retrieval-Augmented Generation (RAG) and index query pipeline using LlamaIndex. The system will index longitudinal speech transcripts and acoustic features, query prospective risk indicators, and output stratified pediatric psychological risk scores.
What you are building
Build a pediatric speech analysis RAG index using LlamaIndex to identify early predictive markers of internalizing disorders.
How work is evaluated
Evaluates index retrieval accuracy and risk level classification based on longitudinal transcripts.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
risk_level_valid
Ensure risk level matches allowed categories
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
risk_prediction_f1
F1 score of predicted risk levels compared to prospective longitudinal ground truth • target: 0.86 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
