I hate Artificial Neural Networks.

All that Zeno managed to show is that philosophers suck at calculus.

1d	comment	What is the way to represent factor variables in scikit-learn while using Random Forests? Converting factors to continuous value is equally bad for RF as for linear regression -- it may decrease your accuracy but it is unlikely that this will completely spoil the model.
1d	revised	Spatial clustering with the constraint that all clusters have equal count edited title
Jun 16	comment	Why does k-NN perform better than SVR and linear regression? Rather log the decision before both making a model and calculating correlation coefficient. If your values have a huge and skewed spread neither SVR optimization target nor Pearson correlation make any sense.
Jun 14	comment	Why does k-NN perform better than SVR and linear regression? The fact that kNN can beat SVM is not really surprising, nevertheless I somewhat feel your problem will look way better after taking a log of decision (at least).
