MACHINE LEARNING WITH STATISTICS

Most machine learning books assume you already know statistics. Most statistics books never get to machine learning. This book is both - taught from first principles, with no gaps in between.

The Basics of Machine Learning and Statistics is a beginner's guide for anyone who wants to truly understand how data, models, and predictions actually work - not just which library function to call. Whether you're a student, a working professional pivoting into AI, or an engineer who's tired of treating ML as a black box, this book takes you from the very first formula to a working neural network.

Across eleven carefully sequenced chapters, you will learn:

• The foundations of statistics - mean, median, variance, probability, distributions, hypothesis testing, and regression - with worked numerical examples for every formula
• The core machine learning paradigms - supervised, unsupervised, and reinforcement learning - explained in plain language with the math made approachable
• Essential algorithms including linear and logistic regression, k-nearest neighbors, decision trees, random forests, support vector machines, K-means clustering, and principal component analysis
• Model evaluation done right - train/validation/test splits, cross-validation, the bias-variance tradeoff, regularization, and hyperparameter tuning
• Working with real data - cleaning, missing values, feature scaling, categorical encoding, feature engineering, and reproducible pipelines
• The future of the field - deep learning, large language models, ethics, fairness, and interpretability
• Three complete end-to-end Python projects - predicting housing prices with regression, segmenting customers with clustering, and classifying handwritten digits with a neural network

Every concept is paired with a worked example. Every formula is followed by a numerical calculation. Every algorithm comes with runnable Python code using scikit-learn, NumPy, pandas, and TensorFlow. The only prerequisite is high-school algebra and the willingness to think carefully.

By the final chapter, you will be able to describe a dataset, fit and evaluate the major model families, distinguish overfitting from underfitting, choose appropriate metrics, prepare messy data for modeling, and build a defensible end-to-end machine learning project - the working skill set of a literate practitioner.

Written by an AI and DevOps engineer with hands-on experience deploying machine learning in production environments, this is the introduction to ML that respects your time, your intelligence, and your need to actually understand what's happening under the hood.

Perfect for: students, self-learners, data analysts, software engineers transitioning to AI, and anyone who has ever asked, "but how does it actually work?"
