Reply to comment by currentscurrents in [Discussion] Is there any alternative of deep learning ? by sidney_lumet

That's really interesting, thanks for the share. Though I wonder if most decision trees still don't converge upon the same solutions as a neural network, even if they're capable of representing the same solutions. If trees don't converge on the same solutions, and NNs outperform trees, that would mean NNs are still needed for training, then the models can be optimized for run-time by basing a tree off the NN.

I know there's a whole field of decision tree learning, but I'm not super up to date on it.

I assume neural networks are better or else we'd be using trees instead.

My goto model (after a linear model) is usually XGBoost. It's nice to see that the theoretical potential of a tree based model is as high as neural network. Though that's not necessarily true of XGBoost's boosted trees, they do perform well, and I really like how fast their training time is.
