# Enhanced Training Dashboard with Real-Time Model Learning Metrics
|
||||
|
||||
## Overview
|
||||
Successfully enhanced the trading dashboard with comprehensive real-time model training capabilities, including training data streaming to DQN and CNN models, live training metrics display, and integration with the existing continuous training system.
|
||||
|
||||
## Key Enhancements
|
||||
|
||||
### 1. Real-Time Training Data Streaming
|
||||
- **Automatic Training Data Preparation**: Converts tick cache to structured training data every 30 seconds
|
||||
- **CNN Data Formatting**: Creates sequences of OHLCV + technical indicators for CNN training
|
||||
- **RL Experience Generation**: Formats state-action-reward-next_state tuples for DQN training
|
||||
- **Multi-Model Support**: Sends training data to all registered CNN and RL models
|
||||
|
||||
### 2. Comprehensive Training Metrics Display
|
||||
- **Training Data Stream Status**: Shows tick cache size, 1-second bars, and streaming status
|
||||
- **CNN Model Metrics**: Real-time accuracy, loss, epochs, and learning rate
|
||||
- **RL Agent Metrics**: Win rate, average reward, episodes, epsilon, and memory size
|
||||
- **Training Progress Chart**: Mini chart showing CNN accuracy and RL win rate trends
|
||||
- **Recent Training Events**: Live log of training activities and system events
|
||||
|
||||
### 3. Advanced Training Data Processing
|
||||
- **Technical Indicators**: Calculates SMA 20/50, RSI, price changes, and volume metrics
|
||||
- **Data Normalization**: Uses MinMaxScaler for CNN feature normalization
|
||||
- **Sequence Generation**: Creates 60-second sliding windows for CNN training
|
||||
- **Experience Replay**: Generates realistic RL experiences with proper reward calculation
|
||||
|
||||
### 4. Integration with Existing Systems
|
||||
- **Continuous Training Loop**: Background thread sends training data every 30 seconds
|
||||
- **Model Registry Integration**: Works with existing model registry and orchestrator
|
||||
- **Training Log Parsing**: Reads real training metrics from log files
|
||||
- **Memory Efficient**: Respects 8GB memory constraints
