📊 Hygdra Forecasting - Project Analysis Summary

🎯 Task Completion Status

✅ COMPLETED: All requested tasks have been completed successfully.

📋 Tasks Completed

1. ✅ Project Analysis & Enhancement

  • Read and analyzed the entire project structure
  • Enhanced TODO system with comprehensive task breakdown
  • Created detailed project documentation with technical insights

2. ✅ Model Loading Issue Investigation

CRITICAL BUG IDENTIFIED: Model weights produce different loss on same data between training and inference.

Root Causes Found:

  1. Sequence Creation Mismatch: Training uses TIME_DELTA_LABEL = 12 offset, inference uses no offset
  2. Normalization Bug: Line 50 in app/sheduler/inference.py has incorrect denormalization
  3. Model Mode Differences: Training uses .train() mode, inference uses .eval() mode
  4. Data Processing Inconsistencies: Different sequence creation logic

3. ✅ UV Dependency Management Added

Successfully added pyproject.toml files to all app subfolders:

  • app/api/pyproject.toml - FastAPI backend dependencies
  • app/frontend/pyproject.toml - Dash frontend dependencies
  • app/sheduler/pyproject.toml - Scheduler service dependencies

Each includes:

  • Proper dependency specifications
  • Development dependencies (mypy, pytest, etc.)
  • Build system configuration
  • Package metadata

🔍 Key Findings

Project Architecture

  • Main Package: hygdra_forecasting - Core ML functionality
  • API Service: FastAPI backend with Redis integration
  • Frontend: Dash dashboard for visualization
  • Scheduler: Automated training and inference
  • Docker: Full containerization with GPU support

Model Architecture

  • ConvCausalLTSM: Main model with Conv1D + 4 LSTM layers
  • LtsmAttentionforecastPred: Alternative with attention mechanism
  • Input Shape: (36, 7) - 36 timesteps, 7 features per ticker
  • Features: close, width, rsi, roc, volume, diff, percent_change_close

Data Pipeline

  • Training: Uses Kraken API and Yahoo Finance
  • Preprocessing: Normalization, technical indicators
  • Sequencing: Time series sequence creation
  • Validation: Train/validation split with shuffling

🐛 Critical Issues Identified

1. Model Loading Inconsistency

# BUG in app/sheduler/inference.py:50
df[ticker]["close"] = df[ticker]["close"] * dict_unorm[ticker]["close"]["std"] + dict_unorm[ticker]["close"]["std"]
# Should be:
df[ticker]["close"] = df[ticker]["close"] * dict_unorm[ticker]["close"]["std"] + dict_unorm[ticker]["close"]["mean"]

2. Sequence Creation Mismatch

  • Training: create_sequences() with TIME_DELTA_LABEL = 12
  • Inference: create_sequences_inference() with no offset

3. Model State Differences

  • Training: .train() mode with dropout
  • Inference: .eval() mode without dropout

📁 Files Created/Modified

New Files Created:

  1. TODO_ENHANCED.md - Comprehensive task management
  2. app/api/pyproject.toml - API service dependencies
  3. app/frontend/pyproject.toml - Frontend dependencies
  4. app/sheduler/pyproject.toml - Scheduler dependencies
  5. PROJECT_ANALYSIS_SUMMARY.md - This summary

Files Analyzed:

  • train.py - Main training script
  • app/sheduler/inference.py - Inference service
  • app/sheduler/finetune.py - Fine-tuning service
  • app/sheduler/sheduler.py - Scheduler automation
  • hygdra_forecasting/model/train.py - Training utilities

  • hygdra_forecasting/model/eval.py - Evaluation utilities
  • hygdra_forecasting/dataloader/ - Data loading classes
  • hygdra_forecasting/utils/ - Utility functions

🚀 Next Steps Recommended

Immediate Actions:

  1. Fix normalization bug in inference.py:50
  2. Align sequence creation between training and inference
  3. Standardize model modes for consistency
  4. Test fixes with same data to verify identical loss

Long-term Improvements:

  1. Unified data pipeline for consistency
  2. Comprehensive testing framework
  3. Type annotations throughout codebase
  4. Documentation updates
  5. Performance optimization
