1. Introduction: Why should engineers use AI/Data Science?
The modern engineering industry is data-driven, whether it's machine vibration data, structural stress data, or energy efficiency data. Artificial Intelligence (AI) and Data Science are essential to:
Efficiency: Analyze and improve the production process or system operation.
Cost Reduction: Switch to predictive maintenance instead of time-based repairs.
Risk Prediction: Predict the damage to a structure or machine before it fails.
The most important tool for working in AI and data science is Python, as it offers comprehensive and easy-to-use libraries that help engineers turn raw data into insights for decision-making.
2. Main content: Project Tutorials (How-to & Step-by-Step)
We'll dive into the application of Machine Learning (ML) in engineering through a sample project using Python :
Project 1: Structural Engineering Data Analysis with Python
The goal of this project is to clean, organize, and understand basic engineering datasets.
Tools/Libraries: Pandas, NumPy, Matplotlib/Seaborn
| step | Description and sample code (Conceptual Code) |
| 1. Load Data | Use Pandas to read a data file (e.g. CSV) that records the vibration/stress values of the structure. |
| 2. Clean Data | Use NumPy and Pandas to handle null values (NaN) and outliers. |
| 3. Create a visualization of the data. | Use Matplotlib or Seaborn to create graphs (e.g. Scatter Plot, Heatmap) to find the relationship between variables (e.g. temperature and vibration). |
Project 2: Machine Learning (AI) to predict performance/damage
This project will use Machine Learning to create a model that can predict the Remaining Useful Life (RUL) or recognize material defects.
Tools/Libraries: Scikit-learn, TensorFlow/PyTorch
| step | Description and sample code (Conceptual Code) |
| 1. Prepare the data set (Feature Engineering) | Prepare data for ML by selecting the features that will be used to predict the outcome (Target Variable). |
| 2. Create a model (Model Training) | Use Scikit-learn to build a Regression model (such as Linear Regression or Random Forest) to predict RUL (continuous values) or use Classification to identify outliers. |
| 3. Evaluation | Evaluate the model performance with statistical metrics (e.g., RMSE, R-squared for Regression or Accuracy, F1-Score for Classification) to confirm that the model is accurate enough for engineering applications. |
Project 3: Sensor Data Management (IoT Data) for Engineering
Managing data from IoT Sensors is essential for Predictive Maintenance because the data is time-series.
Tools/Libraries: Pandas , Statsmodels (for Time-Series Analysis)
| step | Description and sample code (Conceptual Code) |
| 1. Data processing (Preprocessing) | Sort data by time and resample (e.g. from second to minute data). |
| 2. Trend Analysis | Use Time-Series techniques to find the degradation trend of the sensor values (e.g., the rate of increase in vibration over time). |
| 3. Anomaly Detection | Use machine learning or statistical techniques to identify values that deviate from the normal pattern of IoT data. |
3. Essential Tools and Libraries
Data Science work for engineers cannot be without these Python Libraries :
Pandas: For Data Manipulation and Analysis
NumPy: For fast and efficient numerical computing.
Scikit-learn: A standard library for building common machine learning models (ML algorithms).
TensorFlow/Keras/PyTorch: Main frameworks for building Deep Learning models (used for complex tasks such as damage image analysis).
Matplotlib/Seaborn: For data visualization and creating easy-to-understand graphs.
Statsmodels: For statistical analysis and time-series analysis.
Coding Environment (IDE/Notebooks): We recommend using Jupyter Notebook or Google Colab to conveniently write code, run results, and display results simultaneously.
