The MIRAFX Pipeline

Complete ML Training Workflow for Physiological AI

The MIRAFX Pipeline transforms human behavioral data into intelligent systems that understand physiological states. Whether you're developing drowsiness detection for automotive safety, cognitive load monitoring for aviation, or distraction assessment for industrial operations, this integrated workflow takes you from raw data collection to deployed AI models.

What it builds: Machine learning models that detect and predict human states including drowsiness, cognitive load, attention levels, stress, fatigue, and emotional states from facial expressions and behavioral patterns.

Who uses it: Researchers, engineers, and data scientists developing physiological AI for automotive safety systems, clinical assessment tools, human factors research, and adaptive technologies.

Workflow Overview

The MIRAFX Pipeline workflow transforms raw data into trained models through these steps:

Core Workflow:

  1. Collect data through interactive sessions using cognitive tasks
  2. Record synchronized video with microsecond-precision timestamps
  3. Extract facial landmarks and compute raw physical metrics
  4. Generate automatic annotations by fusing self-assessments with performance data
  5. Compute temporal features from landmark and annotation data
  6. Train machine learning models using preprocessed features and annotations

Parallel Processing:

  • Parallelize computational tasks (landmark extraction, automatic annotation, feature extraction) across large datasets for 5-20x performance improvements

Expert Review & Annotation:

  • Visualize synchronized video and signal plots from recorded data, automated annotations, and computed features
  • Review and validate automated annotations against expert knowledge
  • Add expert ground truth labels that enhance model training quality
