ML & Deep Learning Model Training Pipelines

Project Overview

This repository demonstrates how to build and train machine learning (ML) and deep learning (DL) models using consistent, reusable pipeline workflows. A pipeline combines multiple steps — from data preprocessing to model training and evaluation — into a structured and reproducible framework. This helps ensure that training workflows are clean, modular, and maintainable.

The notebook ML_and_DL.ipynb showcases end-to-end model training including:

✔ Data loading and preprocessing
✔ Feature engineering
✔ Training multiple models (ML + DL)
✔ Evaluation and visualization
✔ Using pipelines for systematic model training

Key Concepts Covered

👉 Machine Learning Pipeline: A modular sequence of transformations and model training steps.
👉 Deep Learning Model: A neural network (e.g., MLP, CNN, etc.) trained on the dataset.
👉 Evaluation: Accuracy, loss, and performance metrics on held-out test data.
👉 Reusability: Structuring code to automate repetitive processes.

Notebook Summary

This notebook demonstrates:

Data Loading — Importing dataset(s) for training.
Preprocessing — Handling missing values, scaling/normalization, encoding categories.
Feature Engineering — Creating or selecting the most useful predictive features.
Model Training — Using both:
- Traditional ML algorithms (e.g., Random Forest, SVM)
- Deep Learning models (Neural Networks)
Evaluation — Comparing model performance with metrics such as accuracy, precision, etc.
Pipelines — Structuring sequences of steps for clean workflows.

Pipelines help maintain consistency and make your code easier to reuse and test.

Pipeline Workflow

A typical pipeline sequence implemented in the notebook may include:

Data Preprocessing
Feature Transformation
Model Training
Validation & Evaluation

Pipelines reduce code duplication and improve reproducibility.
