Overview

Мы рассмотрим все теоретические и практические аспекты применения линейной регрессии для предсказания числовых показателей энергопотребления ASHRAE в соревновании на Kaggle вплоть до формирования конечного результата.Курс разбит на 2 части. В первой части мы последовательно пройдем все этапы работы с данными: от видов задач и их постановки до работы с моделями машинного обучения для минимизации предсказательной ошибки. Дополнительно рассмотрим фундаментальные основы построения моделей машинного обучения, базовые метрики и наиболее простые модели - линейную, полиномиальную и линеаризуемую регрессии.Во второй части разберем на практикуме:Особенности процесса анализа данных (ETL): загрузка, очистка, объединение наборов данных с pandas.Проведение исследовательского анализа данных для поиска зависимостей: EDA.Использование sklearn для линейной регрессии.Интерполяция и экстраполяция данных.Расчет метрики качества RMSLE для моделей линейной регрессии.Оптимизация линейной регрессии: выбор наилучших параметров и гиперпараметров.Оптимизация потребления памяти при работе с большими данными.Запасные модели линейной регрессии.Ансамбли линейной регрессии для уточнения предсказания.Экспорт и импорт данных, включая промежуточные.Выгрузка результата для соревнования на Kaggle.
