tidymodels是一組用于建模和機器學(xué)習(xí)的R語言包。無論你是新手還是擁有多年建模經(jīng)驗，這本實踐用書將為數(shù)據(jù)分析師、業(yè)務(wù)分析師和數(shù)據(jù)科學(xué)家展示tidymodels框架如何為你的工作提供一致、靈活的方法。
RStudio的工程師Max Kuhn和Julia Silge展示了通過專注于一種被稱為tidyverse的R方言來創(chuàng)建模型的方法。采用tidyverse原則的軟件共享高層設(shè)計理念和低層語法及數(shù)據(jù)結(jié)構(gòu)，因此學(xué)習(xí)生態(tài)系統(tǒng)的一部分有助于掌握下一部分。你會明白為什么tidymodels框架被人們廣泛使用。
本書內(nèi)容包括：
● 學(xué)習(xí)從頭到尾構(gòu)建模型所需的步驟
● 理解如何流暢地使用不同的建模和特征工程方法
● 研究如何避免建模的常見缺陷，比如過擬合
● 學(xué)習(xí)為建模準備數(shù)據(jù)的實用方法
● 調(diào)整模型以獲得最佳性能
● 使用良好的統(tǒng)計實踐來比較、評估和選擇模型

The animal on the cover of Tidy Modeling with R is a European robin (Erithacus rubecula), native to continental Europe, the United Kingdom, western Russia, and northern Africa.
European robins are grey and brown, with a signature orange chest and white stomach. Males and females look similar, with the primary differentiator being the shape of the beak. They live around forests, plants, or trees. They don’t necessarily migrate significant distances for winter (except for those living further north in Scandinavia and Russia), but females will move short distances away from males, who maintain the same territories in both winter and summer.
European robins typically begin breeding in March and will lay several clutches of 4 to 6 eggs each with an incubation period of 13 to 14 days. The clutches can overlap to a certain extent, with the male feeding the newborns while the female sits on the next clutch. The male bonds with the female by bringing her food, which can look like a mother feeding her young to an untrained observer. Their diet consists of insects, seeds, nuts, and fruits.
European robins have a very high mortality rate in the first year of life. After that, their life expectancy significantly increases. Ten percent of deaths after the first year are a result of fights between robins, as the males are very aggressive and protective of their territories. The orange chest gradually manifests itself in young robins; the initial lack of orange coloring reduces the chances of a fight over territory in their first year, when their chances of death are already so high.
Since 1960, the European robin has been the national bird of Britain, but it is less popular in other parts of Europe. They are a popular symbol of Christmas because Victorian mailmen were known as “redbreasts” due to their uniforms. The American robin is named for its similarity in appearance to the European robin, but they are not actually closely related.
