aumentar o mapa de calor marítimo

Crio um corr()df a partir de um df original. O corr()df saiu 70 X 70 e é impossível de visualizar o mapa de calor ... sns.heatmap(df). Se eu tentar exibir corr = df.corr(), a tabela não se encaixa na tela e posso ver todas as correlações. É uma maneira de imprimir o todo, dfindependentemente do seu...

Como calcular a dimensão VC?

Estou estudando aprendizado de máquina e gostaria de saber como calcular a dimensão VC. Por exemplo: h(x)={10if a≤x≤belse h(x)={1if a≤x≤b0else h(x)=\begin{cases} 1 &\mbox{if } a\leq x \leq b \\ 0 & \mbox{else } \end{cases} , com os parâmetros(a,b)∈R2(a,b)∈R2(a,b) ∈ R^2 . Qual é a dimensão VC...
