pet-projects-ml's Introduction

Репозиторий для хранения и демонстрации DS (ML) пет-проектов

Data science (machine learning) python pet-projects, including the most important methods/attributes to work with dataframes, train models and predict results

Первый проект, показана работа с основными методами sklearn для организации работы деревьев решений - DecisionTrees, выбор метрик и их сравнение/варьирование в зависимости от конкретной задачи, а также различные диаграммы и другие методы визуализации полученных результатов встроенными методами pandas, sklearn
