Other optimized hyperparameters included the maximum depth of the trees (4, 6, 8, 10), the minimum number of samples required for a leaf node (1, 5) and for sub-diving an internal ...
Spletof these hyperparameters include the number of hidden layers, the number of neurons per layer, and gradient decent hyperparameters. 3.3 Support Vector regression (SVR). SVR is a powerful method for solving linear and nonlinear regression problems, and it is used in outlier detection. You should use your training set for the fit and use some typical vSVR parameter values. e.g. svr = SVR (kernel='rbf', C=100, gamma=0.1, epsilon=.1) and then svr.fit (X_train,y_train). This will help us establishing where the issue is as you are asking where you should put the data in the code.
