Mastering Machine Learning with scikit-learn. Apply effective learning algorithms to real-world problems using scikit-learn - Second Edition

Gavin Hackeling

Machine learning is the buzzword bringing computer science and statistics together to build smart and efficient models. Using powerful algorithms and techniques offered by machine learning you can automate any analytical model.This book examines a variety of machine learning models including popular machine learning algorithms such as k-nearest neighbors, logistic regression, naive Bayes, k-means, decision trees, and artificial neural networks. It discusses data preprocessing, hyperparameter optimization, and ensemble methods. You will build systems that classify documents, recognize images, detect ads, and more. You will learn to use scikit-learn’s API to extract features from categorical variables, text and images; evaluate model performance, and develop an intuition for how to improve your model’s performance.By the end of this book, you will master all required concepts of scikit-learn to build efficient models at work to carry out advanced tasks with the practical approach.

Pucuś

Barbara Niedźwiedzka

Pucek był dorosłym zającem i doskonale znał wszystkie zakamarki leśne. Mieszkał na skraju lasu w niedużym domku – w pokoju z kuchnią i łazienką. Obok kuchni był magazyn, w którym szarak przechowywał śrubki, młotki, stary rower, hulajnogę i inne cenne rzeczy. Był bojaźliwy – jak to zając. Może dlatego jego słuchy oklapły, a ogon, czyli omyk ciągle drżał jak listek na wietrze. Parę skoków dalej szarak miał też dużą spiżarnię. Gromadził w niej zapasy na zimę. Leśni przyjaciele mówili, że jest prawdziwym kolegą. Myślę, że to prawda! Zresztą przekonacie się już niebawem.
