Training Monitoring System

The Kai platform includes a comprehensive Training Monitoring System that provides real-time insights into machine learning model training processes. This system is accessible through the admin panel and offers tools for visualizing metrics, managing checkpoints, and tuning model parameters.

Overview

The Training Monitoring System is designed to help administrators and ML engineers:

• Track training progress in real-time
• Visualize performance metrics through customizable charts
• Create and manage model checkpoints during training
• Compare checkpoint performance and model versions
• Fine-tune hyperparameters to optimize model performance
• Rollback to previous model versions when needed

Architecture

The system consists of a parent TrainingMonitor component that integrates three specialized components:

1. MetricsVisualizer: Displays real-time training metrics with customizable charts
2. CheckpointManager: Manages model checkpoint operations (creation, comparison, rollback)
3. ParameterTuner: Allows adjustment of hyperparameters during training

Components

TrainingMonitor

The TrainingMonitor serves as the container component that integrates all training monitoring functionality into a cohesive interface. It provides:

• Tab-based navigation between specialized components
• Unified job ID management
• Shared state for training parameters
• System-wide notifications and alerts

Implementation

The TrainingMonitor is implemented as a React component that dynamically loads its child components and manages state across them:

// Simplified implementation
const TrainingMonitor: React.FC<TrainingMonitorProps> = ({ 
  jobId, 
  modelType,
  onComplete 
}) => {
  const [activeTab, setActiveTab] = useState('metrics');
  
  return (
    <Box>
      <Tabs value={activeTab} onChange=>
        <Tab value="metrics" label="Training Metrics" />
        <Tab value="checkpoints" label="Checkpoints" />
        <Tab value="parameters" label="Parameters" />
      </Tabs>
      
       modelType= />}
       modelType= />}
       modelType= />}
    </Box>
  );
};

MetricsVisualizer

The MetricsVisualizer component provides real-time visualization of training metrics. It offers:

• Interactive line charts for tracking metrics over time
• Customizable chart views and metric selection
• Support for comparing multiple training runs
• Data export and sharing capabilities
• Chart customization options (timeframes, scaling, etc.)

Key Features

• Real-time Updates: Displays training metrics as they're generated
• Multi-metric Visualization: Can show multiple metrics simultaneously (loss, accuracy, etc.)
• Custom Visualization Controls: Timeframe selection, smoothing, and scaling options
• Adaptive Charts: Automatically adjusts to available metrics for different model types
• Performance Comparison: Overlay metrics from previous training runs

Implementation

// Simplified implementation
const MetricsVisualizer: React.FC<MetricsVisualizerProps> = ({ 
  jobId, 
  modelType 
}) => {
  const [metrics, setMetrics] = useState<TrainingMetrics[]>([]);
  const [selectedMetrics, setSelectedMetrics] = useState<string[]>(['loss', 'accuracy']);
  const [timeframe, setTimeframe] = useState<Timeframe>('full');
  
  // Fetch metrics on interval
  useEffect(() => {
    // Implementation details
  }, [jobId]);
  
  return (
    <Box>
      <MetricControls 
        availableMetrics=
        selectedMetrics=
        onMetricsChange=
        timeframe=
        onTimeframeChange=
      />
      
      <MetricsChart 
        data=
        selectedMetrics=
        timeframe=
      />
      
      <MetricsTable 
        data=
        selectedMetrics=
      />
    </Box>
  );
};

CheckpointManager

The CheckpointManager component provides a comprehensive interface for managing model checkpoints during and after training. It enables:

• Viewing all available checkpoints with metadata
• Creating new checkpoints during training
• Comparing metrics between checkpoints
• Rolling back to previous checkpoints
• Managing checkpoint lifecycle

Key Features

• Checkpoint Creation: Create manual checkpoints during training with custom descriptions and tags
• Checkpoint Comparison: Side-by-side comparison of metrics and parameters between any two checkpoints
• Visual Differencing: Highlight parameter differences between checkpoints
• Rollback Capability: Roll back to any previous checkpoint
• Tagging System: Organize checkpoints with customizable tags

Implementation

The CheckpointManager integrates with the backend API to manage checkpoint operations:

// Simplified implementation
const CheckpointManager: React.FC<CheckpointManagerProps> = ({
  jobId,
  modelType
}) => {
  const [checkpoints, setCheckpoints] = useState<Checkpoint[]>([]);
  const [selectedCheckpoints, setSelectedCheckpoints] = useState<string[]>([]);
  const [loading, setLoading] = useState<boolean>(true);
  
  // Load checkpoints using API
  const loadCheckpoints = async () => {
    try {
      setLoading(true);
      const result = await checkpointApi.fetchCheckpoints(jobId);
      setCheckpoints(result);
    } catch (err) {
      // Error handling
    } finally {
      setLoading(false);
    }
  };
  
  // Fetch checkpoints when component mounts or jobId changes
  useEffect(() => {
    loadCheckpoints();
  }, [jobId]);
  
  return (
    <Box>
      
      
      
      
    </Box>
  );
};

ParameterTuner

The ParameterTuner component allows administrators to adjust hyperparameters during training. It provides:

• Real-time adjustment of training parameters
• Visualization of parameter impact on training
• Preset parameter configurations for common scenarios
• Advanced parameter scheduling

Key Features

• Dynamic Parameter Updates: Adjust parameters while training is in progress
• Parameter Presets: Apply predefined parameter sets for common scenarios
• Parameter Validation: Ensure parameters stay within valid ranges
• Parameter Scheduling: Set up automatic parameter changes during training
• Impact Analysis: Visualize the impact of parameter changes on training metrics

Implementation

// Simplified implementation
const ParameterTuner: React.FC<ParameterTunerProps> = ({
  jobId,
  modelType
}) => {
  const [parameters, setParameters] = useState<Record<string, number>>({});
  const [presets, setPresets] = useState<ParameterPreset[]>([]);
  const [loading, setLoading] = useState<boolean>(true);
  
  // Load current parameters
  useEffect(() => {
    // Implementation details
  }, [jobId]);
  
  const handleParameterChange = async (key: string, value: number) => {
    try {
      await parameterApi.updateParameter(jobId, key, value);
      setParameters(prev => ({ ...prev, [key]: value }));
    } catch (err) {
      // Error handling
    }
  };
  
  return (
    <Box>
      <ParameterControls 
        parameters=
        onChange=
        presets=
        onApplyPreset=
      />
      
      <ParameterImpactChart 
        jobId=
        parameterChanges=
      />
    </Box>
  );
};
