Ready to dive deep into the world of
Artificial Intelligence
Machine Learning (AIML)?

Welcome to Session 50 of our End-to-End AIML series! In this milestone session, we cover Model Evaluation and Validation Techniques, critical steps in machine learning that ensure your models are both accurate and generalizable. Proper model evaluation is essential to understand how well your model will perform on unseen data and to prevent issues like overfitting.

What You'll Learn:

Introduction to Model Evaluation: Understand the importance of evaluating machine learning models and how it helps in selecting the best model for your data.
Key Evaluation Metrics:
Accuracy
Precision
Recall
F1-Score
ROC-AUC Curve
Mean Squared Error (MSE) and R-squared for regression models
Validation Techniques:
Train/Test Split: Learn the basics of splitting your dataset into training and testing sets.
K-Fold Cross-Validation: Discover how cross-validation helps in assessing model performance more reliably.
Stratified Cross-Validation: Explore how this variant ensures balanced class distribution in each fold.
Leave-One-Out Cross-Validation (LOOCV): Understand how LOOCV works for smaller datasets.
Handling Overfitting and Underfitting: Learn how model evaluation can help detect overfitting and underfitting and ensure that your model generalizes well to new data.
Hyperparameter Tuning: Discover how techniques like Grid Search and Random Search can help optimize your model by tuning hyperparameters.
Hands-On Coding Example: Follow a step-by-step implementation in Python using Scikit-learn to evaluate and validate machine learning models.
By the end of this session, you’ll be equipped with the best practices to evaluate, validate, and tune machine learning models for real-world applications.
