Slightly off topic, but I hate how publications are written. It seems like authors are purposely using big words and sentences that are often 5-6 lines long in order to make it seem more clever. I find myself often having to reread a sentence in order to understand it. These algorithms are often very simple and can be easily explained. Don't over complicate them.

A lot of the time the verbosity isn't so much to sound more clever as it is to be very specific and explicit about what the author is trying to convey. There's a lot of changing assumed knowledge and jargon in various fields and our use of language changes over time. The publication writing style is an attempt to factor that out.

I would have said 30 years, and I thought I was the optimist :) Anyway I hope you're right and I'm wrong!

That's not a thing to hope for. We haven't solved the value alignment problem, so the longer until we have human or better-than-human AI, the better.

Theory - does empathy rise with intelligence?

Out of curiosity: how far away do you think we are?

I'll say... 5 - 7 years. This is all based on pure speculation, and being a little more than a ML hobbiest. One thing is for sure though - when we do reach that point, everything changes forever.

I'm immensely confused as to how such a number can be put on a discovery.

Then again.. I also don't understand how researchers come up with a yearly budget for making discoveries.

Although I just glanced at a few parts of this, I did not find it to be poorly written. Can you give an example where you thought it was too verbose or unnecessarily complex?

It never ceases to amaze me that the best steps towards achieving AI is to look at how we perceive that a Neuron works and simulate it. And the thing is, we aren't exactly sure why exactly that is.. it's amazing. Sometimes the best thing we can do is imitate nature

TL/DR:

- "We specifically consider the case of...a stacked deep autoencoder (AE), which is a type of neural network designed to encode a set of data samples such that they can be decoded to produce data sample reconstructions with minimal error

- "The first step of the NDL algorithm occurs when a set of new data points fail to be appropriately reconstructed by the trained network...When a data sample’s RE is too high, the assumption is that the AE level under examination does not contain a rich enough set of features to accurately reconstruct the sample.

- "The second step of the NDL algorithm is adding and training a new node, which occurs when a critical number of input data samples (outliers) fail to achieve adequate representation at some level of the network.

- "The final step of the NDL algorithm is intended to stabilize the network’s previous representations in the presence of newly added nodes. It involves training all the nodes in a level with both new data and replayed samples from previously seen classes on which the network has been trained.

Neurogensis? How about neural death as a way to prune large neural networks into more compact ones--now that is a research idea!

I believe several papers have examined efficiently pruning neural networks, but neural death would be better branding ;) ( https://arxiv.org/pdf/1506.02626v3.pdf https://arxiv.org/pdf/1510.00149v5.pdf )

Yann LeCun called a technique for pruning weights "optimal brain damage" back in 1990: http://yann.lecun.com/exdb/publis/pdf/lecun-90b.pdf

Basically trying to achieve a certain level of plasticity in deep neural nets by getting inspiration from https://en.wikipedia.org/wiki/Adult_neurogenesis

To add on to this - they "specifically consider the case of adding new nodes to pre-train a stacked deep autoencoder", by basically keeping track of when certain layers cannot reproduce their input and then adding more nodes+retraining with both new (not reproduced) and old data. It is quite intuitive, basically the most naive and obvious first attempt at the problem (not meant in a condescending way, just want to point out it's not that generalizable and is pretty ad-hoc).

On the other hand, the longer it takes to find general AI, the more powerful hardware will be when it is found.
