Would you labels Google's project of AlphaGo "science" or "engineering"?

Comment author: Lumifer 08 March 2016 07:01:39PM 1 point [-]

Probably engineering -- it is mostly about creating a working "thing" and not about discovering new underlying principles. But the boundary between engineering and applied science can be very fuzzy and there are often feedback loops between the two.

AlphaGo is absolutely science (as well as engineering -- all experimental science involves some engineering). It involves fundamentally new constructions...

It involves fundamentally new constructions

Like what?

The simple construction of using evolutionary learning to refine heuristics that were extracted from deep learning neural networks trained on expert data.

Two previously known and well understood components, put together in a new and novel way that expands our knowledge of what is possible. That is science.

Interesting. I think that is pretty clearly engineering :-)

Of course, this is all a matter of definitions.

It's not an either-or. Some reasonable working definitions: Science is a process by which we expand human knowledge. Engineering is using extant human knowledge to construct artifacts, sometimes repetitive, sometimes novel. Doing some mindless engineering task is not science. But doing something innovative and new makes available new knowledge, which if processed in the correct way is doing science. So you can do both.

You are basically saying that the creation of s'mores was science ("previously known and well understood components, put together in a new and novel way that expands our knowledge of what is possible").

My idea of science is more narrow.

The first person that created a s'more? Yes. Culinary science is a thing.

Would you label the LHC "science" or "engineering"?

Comment author: ChristianKl 08 March 2016 05:39:13PM *  2 points [-]

I think the science/engineering-distinction used by Douglas Knight and Lumifer provides no good model, so you have to ask them.

Comment author: pianoforte611 09 March 2016 03:04:25AM *  1 point [-]

It's both. I think the distinction can be reasonably clean - science aims at understanding via explicitly modeling the process (not necessarily mathematically but often) and then testing the model. The process of building the LHC was engineering, the experiments themselves are part of science.

Comment author: Gunnar_Zarncke 08 March 2016 08:46:27PM 1 point [-]

The LHC is multiple things

  • a set of theoretical results describing what might happen under what physical circumstances
  • an application of said theory to a certain realizable sub-set of technological reality and the prediction of what happens then
  • an engineering effort to build a complex experimental apparatus

(and also a social process driving the people to do all this)

Both. AlphaGo is a major engineering achievement in itself, and a pretty significant step in the empirical science of reinforcement-learning systems.

Comment author: ChristianKl 08 March 2016 05:41:59PM *  1 point [-]

Does that interpretion suggest that the model of science first producing theories/concepts/explanations/recipes and engineering then using them is falsified?

Comment author: Gunnar_Zarncke 08 March 2016 08:42:48PM 0 points [-]

Not strictly. It could very well be that

  • there is parallelism (think technology graphs from games)
  • that science feeds of from intermediate technological results
