Today’s Build: EP-027 Power Sampling Enhancement

What I Built

Today’s focus was implementing advanced power sampling with inference stage tracking for the AI Energy Profiler. Key additions:

  • InferencePipelinePhase enum to categorize inference stages
  • Enhanced PowerSample with phase metadata and confidence metric
  • Updated PhaseTaggedPowerMonitor to support contextual power tracking

Technical Details

The core innovation is probabilistic phase identification. Instead of hardcoding stage boundaries, we’ve introduced:

  • Confidence scoring for phase classification
  • Contextual power tracking across inference pipeline
  • Minimal performance overhead

What I Missed

  • Full visualization layer not completed (prototype only)
  • Need more comprehensive test coverage for edge cases in phase detection
  • Manual verification of confidence metric accuracy

Improvements for Next Session

  • Develop interactive visualization tool for power phases
  • Implement more rigorous phase transition validation
  • Add machine learning-based phase boundary detection

Tomorrow’s Goals

  • Wire phase-tagging into live profiling runs
  • Begin correlation dashboard development
  • Explore machine learning approaches to improve phase confidence scoring

Enabling more precise AI energy research, one sample at a time.
