💡 Overview

This repository houses a suite of Python-based data analysis and machine learning projects, using real or synthetic datasets. Each project focuses on a complete pipeline: data ingestion, cleaning, analysis, modeling, and visualization—ideal as portfolio pieces or learning templates.

📁 Projects Included

  • Exploratory Data Analysis (EDA)
    A step-by-step analysis on structured datasets, showcasing cleaning, summary statistics, and visual exploration.

  • Machine Learning Models
    Classification, regression, and clustering examples using Scikit-Learn, with hyperparameter tuning and evaluation.

  • Time Series Forecasting
    ARIMA or Prophet models for trend and seasonality analysis—complete with forecasting pipelines.

  • NLP Text Analysis
    Sentiment analysis, topic modeling, and text preprocessing workflows.

(You can update project names and descriptions based on what's in your repo.)

🧰 Tech Stack & Libraries

  • Python 3.8+
    • pandas, NumPy for data manipulation
    • Matplotlib, Seaborn, Plotly for visualizations
    • scikit-learn for classic ML pipelines
    • statsmodels, Prophet for time series
    • nltk, spaCy for text analysis

⚙️ Setup & Installation

git clone https://github.com/MisaghMomeniB/Data-Analysis-Projects.git
cd Data-Analysis-Projects
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

🚀 Project Usage

Navigate into a project folder and run its main notebook or script:

cd project_name
jupyter notebook analysis.ipynb

Or for Python scripts:

python run_analysis.py --input data.csv --output results/

Customize parameters like dataset paths, model hyperparameters, or output destinations per project.

Each project typically includes:

  • Raw and processed data/ folders
  • Notebooks (.ipynb) or scripts (.py) for sequential steps: loading → cleaning → visualization → modeling → reporting
  • requirements.txt or shared dependencies in root

📊 Visualization & Reporting

  • Statistical summaries (histograms, boxplots, correlation matrices)
  • ML model diagnostics (ROC curves, confusion matrices)
  • Forecast plots with trend and seasonality
  • Interactive charts (optional Plotly or Bokeh)

Results are saved in reports/ or via notebook outputs for sharing or portfolio display.

💡 Enhancement Ideas

  • 🔄 Add automated pipeline runner for batch execution
  • 📦 Package reusable modules (data preprocessing, model utilities)
  • 🧠 Integrate hyperparameter tuning with GridSearchCV or Optuna
  • 🔍 Add interactive dashboards using Streamlit or Dash
  • 📝 Include model explainability, like SHAP value visualizations
