Je crée un corr()df à partir d'un df d'origine. Le corr()df est sorti 70 X 70 et il est impossible de visualiser le heatmap ... sns.heatmap(df). Si j'essaie d'afficher le corr = df.corr(), le tableau ne correspond pas à l'écran et je peux voir toutes les corrélations. Est-ce un moyen d'imprimer...

Combien de cellules LSTM dois-je utiliser?

Existe-t-il des règles générales (ou des règles réelles) concernant la quantité minimale, maximale et "raisonnable" de cellules LSTM que je devrais utiliser? Plus précisément, je me rapporte à BasicLSTMCell de TensorFlow et à la num_unitspropriété. Veuillez supposer que j'ai un problème de...

Comment calculer la dimension VC?

Im étudie l'apprentissage automatique, et je voudrais savoir comment calculer la dimension VC. Par exemple: h ( x ) = { 10si  a≤x≤bautre h(x)={1if a≤x≤b0else h(x)=\begin{cases} 1 &\mbox{if } a\leq x \leq b \\ 0 & \mbox{else } \end{cases} , avec les paramètres( a , b ) ∈ R2(a,b)∈R2(a,b) ∈ R^2 ....
