Challenge

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.

Delivery guide

How work is evaluated

Evaluation

Evaluates index retrieval accuracy and risk level classification based on longitudinal transcripts.

Datasets

Challenge datasets

Public datasets, plus the private datasets you have access to.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

risk_level_valid

Ensure risk level matches allowed categories

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

risk_prediction_f1

F1 score of predicted risk levels compared to prospective longitudinal ground truth • target: 0.86 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Construct multi-modal document indices using LlamaIndex VectorStoreIndex

  • Extract semantic and structural sentiment markers from child transcript records

  • Implement metadata filtering based on age cohorts and longitudinal touchpoints

  • Query predictive clinical risk profiles while maintaining patient privacy controls
