I think it would help a lot if we brought random forests and SVMs to the same level of performance as DNNs. Demonstrating that more "mechanical" algorithms can be as efficient would dispel some of the anthropomorphism and allow for better analysis of why certain things work.

I also believe that researches have responsibility to outline the limits of their own algorithms in research papers. (For example, presenting examples that aren't recognized or data sets on which the approach doesn't work at all.) That is valuable information and they almost certainly have it at the time of publication.

Not possible, unfortunately

I've occasionally found that SVM's work great for one shot learning if you have good features and nicely labelled dataset. CNN's are really good at extracting features. Once you've extracted features that are generic, using an SVM as the last layer to train while keeping the CNN parameters intact yields great accuracy.

I think that's where we are really headed. A combination of deep learning, boosted trees, svm, evolutionary algos, knowledge graphs e.t.c all stitched together to build stronger AI systems.

Remember our aeroplanes don't flap wings but still carry tonnes of weight and fly half way around the world. Once we discovered fundamentals of aerodynamics a lot of supernatural things were possible.

Same with intelligence, once we discover the essentials of intelligence and mathematically formulate it, supernatural intelligence is very possible. This is the thing that really scares people. I have no idea how close we are to it, but I'm sure it will change society the way internet and mobile phones changed the world.

Wow, I had never considered superintelligence that wasn't at least at some level modeled after the human brain. That is crazy to think about. We could be at the very low end of the spectrum of intelligence I guess.

Homo sapiens is the dumbest creature able to spawn a civilization that evolution could produce.

That's a good comment, and yes, SVM are very powerful in itself, they might not be "deep learning" but they're more powerful than linear learning and good for a lot of cases (as a last layer, as you mentioned, it's a good use case)

Yes, we'll have GAs building CNN architectures, or a mix of several techniques, I'm enthusiastic for what the future holds

It will change the entire world the way humans changed the world. And that's scary.

Kaggle has already proven hundreds of times over that deep learning is not a silver bullet.

Thanks, I'm familiar with Kaggle and how most of the time a Random Forest (or XGBoost, or something like Vowpal Wabbit) will solve your problem

True - until some clever guy proves us all wrong and finds ways to train some multidimensional/complex/deep/... kernel/forest/swarm/... that can learn those nonlinearities that currently only deep nets can be trained to detect (essentially, due to their relative simplicity, I'd say) :-)
Re:The Limitations of Deep Learning by raverbashing on Tuesday July 18, 2017 @05:02AM (#14795199)
I don't think we'll see a deep svm, but if we see one I think we'll have something very powerful

Same for a deep decision tree (forest?). Or maybe a combination of several techniques, etc

Probably comes down to whether the model can be trained with gradient descent (at least in the short term).

A general pre-trained RL guided architecture search (#1) together with more choices of nonlinearity (#2), feature extraction (#3), pooling and memory argumentation (#4) and other tricks (#5) could be very powerful amongst many domains. Make it be able to accept multiple pre-trained models as priors and we're well on our way to general AI or at least a place where most data-scientists could be automated away.

(#1 deepmind had a demo a year back or so that was quite novel) (#2 vaguely remember someone training decision trees with gradient descent; could definitely see a 'randomforest' layer appearing in the middle of deep nets) (#3 just convolutions + tricks really). (#4 neural turing machine etc) (#5 any attention mechanism/any sequence mechanism (rnn/lstm etc)/ any graph relational understanding like the recent deepmind paper).
