🚀 Getting Started

Prerequisites

• Python 3.7+
• Git

Installation

1. Clone the repository:

git clone https://github.com/bobby190805/machine-learning-for-gng.git
cd machine-learning-for-gng

2. Create a virtual environment:

python -m venv .venv

   .venv\Scripts\activate

   • macOS/Linux:

   source .venv/bin/activate

4. Install required dependencies:

pip install numpy matplotlib seaborn scikit-learn jupyter openpyxl pandas

Running the Code

To run the initial analysis:

python lab_01/one.py

To use Jupyter Notebook for interactive analysis:

jupyter notebook

📝 Key Concepts Covered

Data Exploration (lab_01/one.py)

• Loading data from CSV files
• Inspecting dataset shape and structure
• Viewing first and last rows
• Checking column names and data types
• Computing basic statistics (mean, etc.)

Data Analysis Workflow

1. Data Loading - Reading CSV files with pandas
2. Data Inspection - Understanding structure and content
3. Data Cleaning - Handling missing values and data types
