agrandar el mapa de calor marino

Creo un corr()df a partir de un df original. El corr()DF salió 70 X 70 y es imposible de visualizar el mapa de calor ... sns.heatmap(df). Si trato de mostrar corr = df.corr(), la tabla no se ajusta a la pantalla y puedo ver todas las correlaciones. ¿Es una forma de imprimir todo dfsin importar su...

¿Cuántas celdas LSTM debo usar?

¿Existen reglas generales (o reglas reales) relacionadas con la cantidad mínima, máxima y "razonable" de celdas LSTM que debo usar? Específicamente me relaciono con BasicLSTMCell de TensorFlow y la num_unitspropiedad. Suponga que tengo un problema de clasificación definido por: t - number of time...

¿Cómo calcular la dimensión VC?

Estoy estudiando aprendizaje automático, y me gustaría saber cómo calcular la dimensión VC. Por ejemplo: 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} , con parámetros .(a,b)∈R2(a,b)∈R2(a,b) ∈ R^2 ¿Cuál es la dimensión...
