Sample script for vibration analysis using ML
python3 -c "
import pandas as pd
from sklearn.ensemble import IsolationForest
import numpy as np
Load vibration data (example)
data = pd.read_csv('vibration_data.csv')
model = IsolationForest(contamination=0.1)
model.fit(data[['frequency', 'amplitude']])
predictions = model.predict(data[['frequency', 'amplitude']])
data['anomaly'] = predictions
data.to_csv('anomaly_results.csv')
"
Windows PowerShell for AI Log Analysis:
Install Python and ML libraries via Chocolatey
choco install python -y
python -m pip install pandas scikit-learn
Use Windows Event Log for anomaly detection
Get-WinEvent -LogName System -MaxEvents 1000 |
Where-Object {$_.LevelDisplayName -eq "Error"} |
Export-Csv -Path errors.csv
Run a simple Python script for pattern recognition
python detect_anomalies.py --input errors.csv --output report.json
