Probability Theory is the study of uncertainty. It helps us understand and predict the likelihood of future events based on a mathematical framework. Think of it as forward-looking.
Statistics, on the other hand, focuses on analyzing data to draw inferences. Itโs backward-lookingโworking with observed data to uncover patterns, trends, or probabilities.

Understanding Probability and Statistics isnโt just academicโit empowers you to build better models, interpret results effectively, and tackle real-world challenges with confidence.
For example:
Working with Probabilistic Models like Gaussian Mixture Models (GMMs).
Utilizing Statistical Techniques to evaluate model performance using confidence intervals and hypothesis testing.
Whether youโre fine-tuning hyperparameters or working on feature engineering, these foundational concepts ensure your ML solutions are both robust and interpretable. ๐ง ๐ก
