Sklearn logistic regression, plotting probability curve graph
I’m trying to create a logistic regression similar to the ISLR’s example, but using python instead But I keep getting the graph on the left, when I want the one on the right: Edit: plt.scatter(x,LogR.predict(x)) was my second, and also wrong guess. Answer you use predict(X) which gives out the pre…
Top 10 features SVC with rbf kernel
I’m trying to get the top 10 most informative (best) features for a SVM classifier with RBF kernel. As I’m a beginner in programming, I tried some codes that I found online. Unfortunately, none work. I always get the error: ValueError: coef_ is only available when using a linear kernel. This is th…
Cross validation with grid search returns worse results than default
I’m using scikitlearn in Python to run some basic machine learning models. Using the built in GridSearchCV() function, I determined the “best” parameters for different techniques, yet many of these perform worse than the defaults. I include the default parameters as an option, so I’m s…

Python and SPSS giving different output for Logistic Regression
Code: Here’s the dataset Result: Now I added the same data in spss.Analyse->Regression->Binary Logistic Regression. I set the corresponding Y -> dependent and XT -> Covariates. The results weren’t even close. Am I missing something in python or SPSS? Python-Sklearn Answer SPSS Logistic…

sklearn Clustering: Fastest way to determine optimal number of cluster on large data sets
I use KMeans and the silhouette_score from sklearn in python to calculate my cluster, but on >10.000 samples with >1000 cluster calculating the silhouette_score is very slow. Is there a faster method to determine the optimal number of cluster? Or should I change the clustering algorithm? If yes, which i…
