Practical Data Science using Python - Naive Bayes - Model Building and Optimization

The video tutorial covers the process of building a predictive model using the Gaussian Naive Bayes algorithm. It begins with importing necessary libraries and splitting data into training and testing sets. The tutorial explains the importance of using a random state for reproducibility. It then demonstrates creating and training the model, followed by evaluating its performance using a confusion matrix. The model is tested on unseen data to check its generalization capability. The tutorial concludes with a discussion on further investigations using other performance metrics.
