# Лабораторная 5
|
||||||
|
## Вариант 9
|
||||||
|
|
||||||
|
## Задание
|
||||||
|
Использовать Ласо-регрессию, самостоятельно сформулировав задачу. Оценить, насколько хорошо она подходит для решения сформулированной вами задачи.
|
||||||
|
|
||||||
|
Задача:
|
||||||
|
|
||||||
|
Можно использовать регрессию для прогнозирования заработной платы на основе опыта работы (experience_level), типа занятости (employment_type), местоположения компании (company_location) и размера компании (company_size).
|
||||||
|
|
||||||
|
## Описание Программы
|
||||||
|
Программа представляет собой пример использования Lasso регрессии для прогнозирования заработной платы на основе различных признаков.
|
||||||
|
|
||||||
|
### Используемые библиотеки
|
||||||
|
- `pandas`: Библиотека для обработки и анализа данных, используется для загрузки и предобработки данных.
|
||||||
|
- `scikit-learn`:
|
||||||
|
|
||||||
|
train_test_split: Используется для разделения данных на обучающий и тестовый наборы.
|
||||||
|
|
||||||
|
StandardScaler: Применяется для нормализации числовых признаков.
|
||||||
|
|
||||||
|
OneHotEncoder: Используется для кодирования категориальных признаков.
|
||||||
|
|
||||||
|
Lasso: Линейная модель Lasso для обучения регрессии.
|
||||||
|
|
||||||
|
Pipeline: Позволяет объединять шаги предварительной обработки данных и обучения модели в пайплайн.
|
||||||
|
|
||||||
|
- `matplotlib`: Используется для визуализации коэффициентов модели в виде горизонтальной столбчатой диаграммы.
|
||||||
|
- `numpy`: Использована для работы с числовыми данными.
|
||||||
|
|
||||||
|
### Шаги программы
|
||||||
|
|
||||||
|
**Загрузка данных:**
|
||||||
|
|
||||||
|
Используется библиотека pandas для загрузки данных из файла ds_salaries.csv.
|
||||||
|
|
||||||
|
**Предварительная обработка данных:**
|
||||||
|
|
||||||
|
Категориальные признаки ('experience_level', 'employment_type', 'company_location', 'company_size') обрабатываются с использованием OneHotEncoder, а числовые признаки ('work_year') нормализуются с помощью StandardScaler. Эти шаги объединены в ColumnTransformer и используются в качестве предварительного обработчика данных.
|
||||||
|
|
||||||
|
**Выбор признаков:**
|
||||||
|
|
||||||
|
Определены признаки, которые будут использоваться для обучения модели.
|
||||||
|
|
||||||
|
**Разделение данных:**
|
||||||
|
|
||||||
|
Данные разделены на обучающий и тестовый наборы в соотношении 80/20 с использованием train_test_split.
|
||||||
|
|
||||||
|
**Обучение модели:**
|
||||||
|
|
||||||
|
Используется линейная модель Лассо-регрессия, объединенная с предварительным обработчиком данных в рамках Pipeline.
|
||||||
|
|
||||||
|
**Оценка точности модели:**
|
||||||
|
|
||||||
|
Вычисляется коэффициент детерминации (R^2 Score) и среднеквадратичная ошибка (Mean Squared Error) для оценки точности модели.
|
||||||
|
|
||||||
|
**Вывод предсказанных и фактических значений:**
|
||||||
|
|
||||||
|
Создается DataFrame с фактическими и предсказанными значениями и выводится в консоль.
|
||||||
|
|
||||||
|
**Визуализация весов (коэффициентов) модели:**
|
||||||
|
|
||||||
|
Строится горизонтальная столбчатая диаграмма для визуализации весов (коэффициентов) модели.
|
||||||
|
|
||||||
|
### Запуск программы
|
||||||
|
- Склонировать или скачать код `main.py`.
|
||||||
|
- Запустите файл в среде, поддерживающей выполнение Python. `python main.py`
|
||||||
|
|
||||||
|
### Результаты
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Точность модели составляет всего 39%, что является довольно низким показателем
|
||||||
|
|
||||||
|
MSE довольно высок, что указывает на то, что модель не слишком хорошо соответствует данным и допускает ошибки в предсказаниях
|
||||||
|
|
||||||
|
Фактические и предсказанные значения: видно, что модель часто недооценивает или переоценивает заработную плату. Например, для индексов 563 и 289 фактическая заработная плата выше, чем предсказанная.
|
||||||
|
|
||||||
|
Изменение alfa не особо улучшает общую картину, поэтому, можно сделать вывод, что следует выбрать другой алгоритм.
