"recognition ... irrespective of scale, distortion and noise" sounds pretty interesting. Are these capabilities outside of current NNs? I'm familiar with NNs ignoring noise, but not scale. But my NN investigations are several years old... I wonder if distortion includes any degree of rotation. I don't have time for the demo this night. -- Forwarded message -- From: Numenta, Inc. <[EMAIL PROTECTED]> Date: Mar 20, 2007 6:30 PM Subject: Numenta Newsletter: March 20, 2007 To: [EMAIL PROTECTED] Numenta, Inc. Newsletter March 20, 2007 Dear newsletter subscriber: I am pleased to make several announcements regarding the Numenta Platform for Intelligent Computing (NuPIC). First, we now have available on our web site a demonstration program using the Pictures example which enables recognition of simple line drawings irrespective of scale, distortion and noise. This demo is a Windows(r) client application, and is very easy to use and install. The Windows program accesses NuPIC running on the Numenta Linux cluster in California to perform the recognition task, so you do not need to have Linux installed on your local machine. However, you must be connected live to the Internet in order to use the demo. You can find the demo here: http://www.numenta.com/about-numenta/technology/pictures-demo.php The purpose of this demo is to give you a sense of the capabilities of the platform without having to install the platform itself. And, the demo is a lot of fun to use! (Note that the complete platform only is available on Linux and MacOS today - see below for more information about NuPIC and Windows.) The demo is particularly well-suited for non-engineers, as well as being a good starting point for those engineers who want to get a feel for the platform before going through the full installation process. Second, several developers have commented in our forums expressing interest in a Windows development environment. I'd like to let you know that we are working on this request, and you will see us respond in two phases. We shortly will have information on better packaging of a virtual Linux machine running under Windows. In addition, we plan to add the ability to run NuPIC on native Windows, but that will take longer. Those of you who have subscribed to the developer newsletter will receive further details shortly. Finally, I wanted to let you know that we are pleased with the response to our launch. We've had nearly 2000 people download the platform, and have been excited to watch the forum and wiki sections become active. We're just at the beginning of an exciting new era, and want to thank you for your early and enthusiastic participation.

I tested this and it is very very poor at invariant recognition. I am surprised they released this given how bad it actually is. As an example I drew a small "A" in the bottom left corner of their draw area. The program returns the top 5 guesses on what you drew. The letter A was not even in the top 5, much less being the first best guess... Back to the drawing board for this fundamental problem that no one has solved...including anyone on this list.

Re: [agi] Fwd: Numenta Newsletter: March 20, 2007
Having had a long standing interest in machine vision I find this demo deeply unimpressive. It's a classic example of the kind of "toy" problem which may work well within its very restricted domain but when supplied with more realistic data (i.e. photos of real objects) fails catastrophically. Scalability from theoretical principle to practical perception system is a key requirement. Many folks in the machine vision world become seduced by two dimensions. Because photos or TV screens are two dimensional they reckon so must be the processes which interpret them. It should be remembered that two dimensional objects in a photo are just shadows of a higher dimensional realm. I believe that we can only recognise 2D objects because during the early stages of our lives we have learned to be able to abstract out certain commonly observed shadows from the full range of spatio-temporal experience, effectively substituting a higher dimensional representation with a quick lookup. Fundamentally though we are creatures designed to interpret three or four dimensional events (or more if you include multi-modal integration). I believe that the invariant object recognition problem has already been solved, but that most people just don't yet realise it. If you imagine that the fundamental mode of representation of the world consists of three or four dimensional objects, with quick lookups for common 2D shadows, then its quite easy to see how its possible to view a photo, perform a mental transformation and then draw the object shown in the photo as it might appear from a different angle. This skill of course relies upon early embodied experiences of the world. In an AGI context such experiences could be gained either using a physical robot, or within a simulated world such as Ben's. The ability to perform mental transformations isn't only useful for vision, and I think it's no coincidence that skilled scientists, mathematicians or other creative people are often described to possess good "mental imagery" skills.

I tried to build such a vision-centric AGI a couple We know that logic is easy. People only had to learn to deal with it evolutionary only recently, and computers can do serial symbol string transformations quite rapidly. Already computer-assisted proofs have transformed a branch of mathematics into an empirical science. Building world/self models in realtime from noisy, incomplete and inconsistent data takes a lot of processing, and parallel processing. For some reason traditionally AI considered the logic/mathematics/formal domain for hard, and vision as easy. It has turned out exactly the other way round. Minsky thought porting SHRDLU to the real world was a minor task. Navigation and realtime control, especially cooperatively is hard. We've desintegrated into discussion minutiae (which programming language, etc.) but the implicit plan is to build a minimal seed that can bootstrap by extracting knowledge from its environment. The seed must be open-ended, as in adapting itself to the problem domain. I think vision is a reasonable first problem domain, because insects can do it quite well. You can presume that a machine which has bootstrapped to master vision will find logic a piece of cake. Not necessarily the other way round. I understand some consider self-modification a specific problem domain, so a system capable of targeted self-inspection and self-modification can self-modify itself adaptively to a given task, any given task. I think there is absolutely no evidence this is doable, and in fact there is some evidence this is a Damn Hard problem.

Of course, the same dynamic happens across all areas of AI (creating specialized rather than general methods being a better way to get impressive, demonstrable incremental progress), but it happens particularly acutely with vision Gary Lynch, in the late 80's, made some strong arguments as to why olfaction might in some ways be a better avenue to cognition than vision. Walter Freeman's work on the neuroscience of olfaction is inspired by this same idea. One point is that vision processing has an atypically hierarchical structure in the human brain. Olfaction OTOH seems to work more based on attractors and nonlinear dynamics (cf Freeman's work), sorta like a fancier Hopfield net (w/asymmetric weights thus leading to non fixed point attractors). The focus on vision has led many researchers to overly focus on the hierarchal aspect rather than the attractor aspect, whereas both aspects obviously play a bit role in cognition.

Vision (or an equivalent high-bandwidth channel, direct depth perception by TOF, or LIDAR, whatever) is a basic instrument for knowledge extraction.

Only parts of the visual processing pathway are "hardwired" (not really, and it's not a linear thing at all), and of course the upper stages use every trick the neocortex can muster. So, no, I don't think you can trivialize vision, or postpone it. > Of course, the same dynamic happens across all areas of AI > (creating specialized rather than general methods being a better > way to get impressive, demonstrable incremental progress), but it happens > particularly acutely with vision > > Gary Lynch, in the late 80's, made some strong arguments as to why > olfaction might in some ways be a better avenue to cognition than vision. > Walter Freeman's work on the neuroscience of olfaction is inspired by > this same idea. The bit rate you get from olfaction is really low. Yes, you can sense gradients, and if you code everything with volatile carriers you can recognize about everything. What I don't like about olfaction is that it's evolutionary even older than vision, and directly wired to attention allocation (emotion) processes. It's like vision, only without the advantages, and even more hardwired. > One point is that vision processing has an atypically hierarchical > structure in the > human brain.

If we were given a bunch of $$ to embody Novamente in a robot today, and I had to design a vision system for Novamente, I would not try to imitate human visual cortex. Rather, I would * use a combination of lidar and camera input * write code that took this combined input to make a 3D contour map of the perceived surfaces in the world * use standard math transforms to triangulate this contour map * use some AI heuristics (with feedback from the more general AI routines) to approximate sets of these little triangles by larger polygons * finally, feed these larger polygons into the "polygon vision" module we have designed for NM in a sim-world context This is not what the human brain does, but I don't see why it wouldn't work OK -- though I'm sure a whole lot of "small problems" would emerge requiring ample tuning Novamente is not supposed to be an emulated brain. The interesting cognitive problems of vision processing arise at the level of "polygon vision" and don't have that much to do with the lower levels.

I think making direct comparisons between computational power and the animal kingdom has always been a questionable exercise, but I generally agree with trying to tackle problems in a similar order that evolution did, because evolution needed to find incremental solutions. I've long wanted to build an intelligent robot, and by that I mean *really* intelligent, not just faking it for a few minutes with some Eliza-like program. I would like to develop systems for abstract reasoning and concept formation, but unless the robot can actually see and experience its world these reasoning skills are totally useless (unless of course it were a super-arrogant robot - "I'm so smart I don't even need to be able to see, because in my state of singularitarian enlightenment I know the complete state of the universe!"). So I got stuck on the vision problem, and there I have remained to this day.

I'm also following the same approach which is a very straightforward application of standard engineering techniques. The logistics of doing this are quite complicated, involving camera calibration, correspondence matching and probabilistic spatial modelling and I think the sheer complexity (and drudgery) of the programming task is the reason why few people have ever attempted to do this so far. Being able to create large scale voxel models which can be maintained in a computationally efficient manner suitable for real time use also involves some fancy algorithms. I would agree that where things start to become interesting are at the polygon level, but you still need to maintain an underlying voxel model of space because you can't calculate probability distributions accurately using polygons alone. - This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=303
Re: [agi] Fwd: Numenta Newsletter: March 20, 2007
I've read the whitepaper on HTM's and NuPIC. It seems more of a marketing strategy to attract laypeople, since I can't see anything it can solve that a NN (a recurrent and well designed/evolved one with a little preprocessing of input) can't. On 3/21/07, Chuck Esterbrook <[EMAIL PROTECTED]> wrote: "recognition ... irrespective of scale, distortion and noise" sounds pretty interesting. Are these capabilities outside of current NNs?

Newsletter March 20, 2007 Dear newsletter subscriber: I am pleased to make several announcements regarding the Numenta Platform for Intelligent Computing (NuPIC). First, we now have available on our web site a demonstration program using the Pictures example which enables recognition of simple line drawings irrespective of scale, distortion and noise. This demo is a Windows(r) client application, and is very easy to use and install. The Windows program accesses NuPIC running on the Numenta Linux cluster in California to perform the recognition task, so you do not need to have Linux installed on your local machine. However, you must be connected live to the Internet in order to use the demo. You can find the demo here: http://www.numenta.com/about-numenta/technology/pictures-demo.php The purpose of this demo is to give you a sense of the capabilities of the platform without having to install the platform itself. And, the demo is a lot of fun to use! (Note that the complete platform only is available on Linux and MacOS today - see below for more information about NuPIC and Windows.) The demo is particularly well-suited for non-engineers, as well as being a good starting point for those engineers who want to get a feel for the platform before going through the full installation process. Second, several developers have commented in our forums expressing interest in a Windows development environment. I'd like to let you know that we are working on this request, and you will see us respond in two phases. We shortly will have information on better packaging of a virtual Linux machine running under Windows. In addition, we plan to add the ability to run NuPIC on native Windows, but that will take longer. Those of you who have subscribed to the developer newsletter will receive further details shortly. Finally, I wanted to let you know that we are pleased with the response to our launch. We've had nearly 2000 people download the platform, and have been excited to watch the forum and wiki sections become active. We're just at the beginning of an exciting new era, and want to thank you for your early and enthusiastic participation.

I have seen no general/good logic based system yet, have you? "computer-assisted proofs" is a specialized domain and doesn't make a dent in AGI IMO.

Regardless of how easy Minsky or others thought porting from small artificial domains to the real thing would be, that is hardly the point. I agree 100% that "Navigation and realtime control" is a hard problem but so are higher level systems like language and semantic learning. AGI needs both and needs them to communicate intelligently. > We've desintegrated into discussion minutiae (which programming language, etc.) > but the implicit plan is to build a minimal seed that can bootstrap by > extracting knowledge from its environment.

It's funny how many times you have mentioned parallel hardware and other esoteric minutiae of a very low level but I for one, have enjoyed that info very much. I too, have worked with robotics, sonar range finders, micro controllers etc. I appreciate how hard it is to deal with real world data, but that is hardly all that an AGI should be capable of. What evidence or experiments do you have to substantiate that "a machine which has bootstrapped to master vision will find logic a piece of cake"? To dismiss whole quadrants of AI development with just a conclusion, doesn't seem very tolerant or warranted from the current data. The ability of "self-inspection and self-modification" is a prerequisite IMO to creating a system that doesn't need to be hand coded in it's entirety by human programmers. It is possible that some relatively small amount of code could be used and all the smarts could be into the data but history has shown IMO that as the complexity of the data goes up, sub-languages are created to make sense of the data. As the level of interpreter goes up, the speed falls precipitously. Data and programs have been shown in many ways to be interchangeable with some problems going one way and others going the other. Do you believe that some tiny (relative to the size of the AGI) algorithm can be found that will magically create all the systems required for AGI intelligence? I am not sure what you mean exactly by "no evidence". I have made programs that create other programs (on the fly) for almost 20 years. The chances any of these generated programs would be the same is highly unlikely. I don't presume to stretch that into implying I have created a program to produce programs for "any given task" but I don't think your (or my) brain can do that either. > Do you think this is arbitrary and unreasonable?

You're just hoping you only have to do one thing so you can forget about all the other stuff that is required. And if i could pick things that wouldn't be needed in a seed AI, it would be real-world vision and motor skills. I agree that understanding movement and diagrams and figures is essential to thought, but why would a computer program need to do recognize a picture of a chair or a picture of a horse or be able to track a flying bird in the sky? I don't think that's required for most problems. I also don't see how you get to all other thoughts from there?

I agree. you can only do some minor self-modification if you don't fully understand your inner workings/code. I still think most of this AGI will have to coded by hand, and it will be a lot of software engineering and not the romantic seed AI or minimal subset of 10 perfect algorithms...

Darwinian co-evolution is a highly biased stochastical process. Seeds are one-way hashes (morphogenetic code expands the small seed into a structure which is appropriately positioned (environment-shaped) to extract knowledge from the environment (aka doting parents). Such seeds can be relatively tiny, see fertilized human eggs (the womb does not seem to contribute noticeable amounts of complexity). Hence they contain far less complexity than an adult, winning which by stochastical process, unbiased or otherwise, takes terrible odds. > You're just hoping you only have to do one thing so you can forget about > all the other stuff that is required. No. I don't think that other stuff required can be done. This is the same reason I don't subscribe to SENS. I thought this was unlikely when I was a 15 year old, and I still think it's unlikely as a 40 year old. > And if i could pick things that wouldn't be needed in a seed AI, it would be > real-world vision and motor skills.

I have reasons to suspect that a system can't understand its inner workings well enough to do radical tweaks. Well, we can (in theory) mushroom our cortex by a minimal genetic tweak. That's a trivial modification, which doesn't reengineer the microarchitecture. Live brain surgery on self or a single copy doesn't strike me as a particularly robust approach. Add a population of copies, and a voting selection or an external unbiased evaluator, and you're already in Darwin/Lamarck country. > I still think most of this AGI will have to coded by hand, and it will I don't think this is doable by mere humans. This is a few orders of magnitude below of what the maximum complexity ceiling is (tools only take you that far). If AI is numerics, Fortran+MPI would be enough. C would be arguably less painful. If AI is not numerics, you're equally screwed, whether this is Lisp, Erlang, Ruby or Fortran. > be a lot of software engineering and not the romantic seed AI or minimal To clarify, I'm only interested in ~human equivalent general AI, and only in co-evolution from a reasonable seed pool in a superrealtime virtual environment heavily skewed towards problem-solution as fitness function as a design principle. The only reason for this is that it looks as if all other approaches are sterile. You're of course quite welcome to prove me wrong by delivering a working product. > subset of 10 perfect algorithms... Seems like people don't seem to > want to put in all the energy and keep looking for a quick solution My estimate is several % of yearly GNP for several decades for a likely success by above design mechanism.

I'm quite ready to offer them. However, nontrivial (and anything less wouldn't do) mails take a lot of time which I currently do not have. Because of this I tend to postpone such difficult mails, and deal with easier mails (such as basic quoting netiquette) out of sequence.

In my opinion, those would be viable things to include in a proto-AGI. They don't lead as directly to conceptualizations which help communicate with human beings but they could be used for conceptual bootstrapping. It seems that humans (and other animals, to the extent you believe they think) are made by building a general structure capable of learning the nature of the universe, with evolutionarily-discovered optimizations that reduce the learning time. It is not hard to see how "grounding" that process in perception provides a natural sequence of concepts -- spatial regularities leading to spatial relationships and simple mathematics; temporal regularities leading to causality, and so on. From there, analogical reasoning mechanisms have a broad base of material to work from. If such a learner tries to start with less primitive input -- for example, feeding it text from the web --it's not as clear (to me at least) how it can "grab on" to the primitive elements and build on them. Is there a path from letter sequences to their meaning that can reasonably be learned? I have been following your discussions on this list for some time and finally decided to say something.
