whether the AI can test these policies. Even if the AI can find pernicious policies that rank high on its objective function, it will never implement them unless it can ascertain this fact

I don't know if the AI should be taking responsibility for testing its own policies, especially in the initial stages. We should have a range of tests that humans apply that the formative AI runs on each iteration so that we can see how it is progressing.

This is the fundamental problem that is being researched - the top layer of abstraction would be that difficult to define one called "Be Friendly".

Instead of friendly AI maybe we should look at "dont be an asshole" AI (DBAAAI) - this may be simpler to test and monitor.

These are all task specific problem definition issues that occurred while fine tuning algorithms (but yes they do show how things could get out of hand)

Humans already do this very well, for example tax loopholes that are exploited but are not in the 'spirit of the law'.

The ideal (but incredibly difficult) solution would be for AI's to have multiple layers of abstraction, where each decision gets passed up and is then evaluated as "is this really what they wanted", or "am I just gaming the system".

Would minimising the number of CPU cycles work as a lazy incentive.

This assumes that lesser CPU cycles will produce an outcome that is satisified rather than optimised, though in our current state of understanding any optimisation routines take a lot more computing effort than 'rough enough' solutions.

Perhaps getting the AGI's to go Green will kill two birds with one stone.

Comment by djm on [link] Thoughts on defining human preferences · 2015-04-01T01:34:22.107Z · score: 0 (2 votes) · LW · GW

My personal hypothesis is that all human preferences are transient preferences, produced as flashes of positive or negative affect towards some mental concept.

I like that. People do change preferences, a lot - there was that [not very accurate] quote saying (US Centric) along the lines of "If you under 25 and vote republic, you have no heart" "If you over 25 and vote liberal you have no brains"

The most difficult part of this is that people have ingrained beliefs and preferences that will make them unhappy if the other side is picked - rational or not, we cant pick preferences that make all people happy.

For example

Group1 prefers more taxes for social services and hates social injustice

Group2 hates higher taxes

So for Group1 to be happy the Tax_rate should be between 0.2 -> 0.4

but this makes Group2 unhappy as their preferred tax rate is between 0.05 -> 0.15

There is no value in tax_rate that makes all groups happy.

Even if this were solved with infiniate social services and zero tax rates the million other disparate preferences - whether rational or not would cause bigger issues (religeous | athiest, vi | emacs, etc)

Even without an AI, the current trend may well have a world where there is a blurring of real Football matches and simulations.

Certainly you can’t keep an AI safe by using such a model of football

I used to think that a detailed ontological mapping could provide a solution to keeping AI's safe but have slowly realized that it probably isn't likely to work overall. It would be interesting to test this though for small specifically defined domains (like a game of football) - it could work, or at least it would interesting to make a toy experiment to see how it could fail.

This in an interesting article, though necessarily abstract - how can we take this to implement an actual AI detector?

This could be the combination of research in the areas of antivirus software, network detection and intrusion, stock market agents along with some sort of intelligence honeypot (ie some construed event / data that exists for a split second that only an AI could detect and act on)

almost all agents are "enemies" to resource gathering agents, as they use up precious resources

If this were a friendly AI, shouldn't the utility function of the gathering agent take sharing / don't be greedy into account. Though as AI development advances we can't be sure that all governments / corporations / random researchers will put the necessary effort into making sure their intelligent agent is friendly.

That would likely work for initial versions of an AI, but I still cant help feeling that this is just tampering with the signal and that an advanced AI would detect this.

Would it not question the purpose of the utility function around detecting thermodynamic miracles - how would this work with its utility function to detect tampering or false data.

If I saw a miracle, I would [hope] my thinking would follow the logic below

a) it must be a trick/publicity stunt done with special effects b) I am having some sort of dream / mental breakdown / psychotic episode c) some other explanation I don't of

I don't think an intelligent agent would or should jump to "it's a miracle", and I would be concerned of its response if/when it does realise that it has been tricked all along.

I think the idea of having additional agents B (and C) to act as a form of control is definitely worth pursuing, though I am not clear how it would be implemented.

Is 'w' just random noise added to the max value of u?

I dont think it is a problem to have few connections. Everyone starts with zero connections at the start, and many (if not most?) people only use it occasionally.

Comment by djm on Why do you really believe what you believe regarding controversial subjects? · 2015-01-04T23:15:42.680Z · score: 2 (2 votes) · LW · GW

I think there are several levels to this question:

  1. Any issue based on Politics or Religion will have experts on both sides arguing for their case based on their own personal choice and biases - these are more often than not, arguments and discussions rooted entirely on opinion.

  2. For controversial issues in Science and Economics I will try to determine if there are any biases based on point 1. In some cases this becomes visible based on the political leanings of the Scientists and / or corporate sponsorship of the study.

  3. In the Maths world there doesn't seem to be any controversial issues over the results (which is why I kind of like maths a lot!), however there are many issues on which approach to take and how useful a result is. For those sorts of predictive issues I don't usually have a strong opinion

So in general, it comes down to what the biases are. Everyone has an opinion, and these are (or ought to be) less relevant the deeper you get into the Science and Maths.

Instead of using a name like a_lurker and asking for PM's I would suggest going trying to be a little more public - your goal should be to display to potential employers that you can code. This is actually harder than it sounds, as programmers (especially self taught) are more likely to be introverted and don't like marketing themselves. [from my personal perspective]

Some suggestions would be:

  1. Pick some sort of professional sounding name for yourself (doesn't have to be a business name) that you want to be known as - better if it is rare on google. You will use this name to promote your knowledge and collaboration on many websites

  2. Register a domain - even if it is a .info with a simple About you page, saying you are looking for work and your resume. This website should be in your email signature and plugged on other site below.

  3. Start a github account (learn git first) and publish something - anything that you think was good code [as long as it isn't the answer to any of your course assignments]

  4. Answer questions on Stackoverflow with your professional name - and ask questions. Don't spam it, but don't be afraid to ask stupid questions.

  5. Get a linkedin account and grow your network there

Happy to answer any PM's you have, but you should think about promoting yourself if you want work.

Cheers,

Therefore, they cannot identify "that computer running the code" with "me", and would cheerfully destroy themselves in the pursuit of their goals/reward.

My general rule of thumb is

if customer.dictates('specific language')
        use('specific language') # usually Java / PLSQL / .Net
else
        use('Python')
except error('too slow')
        use('C')

I love the simplicity and power of Python and will use it to prototype proof of concepts (not so much GUI work - would use HTML or .NET for that). For me, Python really makes programming a lot of fun again and though it is slower, I haven't yet had the need to shell out to C code though I expect I will soon.

Automatic construction of general interfaces would be tricky to say the least. It would surely have to depend on why agentA needs to interface with agentB in the first place - for general data transfer (location , status, random data) it would be fine, but unless both agents had the understanding of each others internal models/goals/thought processes it seems unlikely that they would benefit from a transfer except at an aggregate level

Good question. You may think it would be a better overall outcome to show the manipulative one to shock the programmers into breaking the law to (possibly) halt the other AI, but then it is no longer an FAI if it does this.

Interesting post - while I don't have any real answers I have to disagree with this point:

"Why do you think your computer is not conscious? It probably has more of a conscious experience than, say, a flatworm or sea urchin. (As byrnema notes, conscious does not necessarily imply self-aware here.)"

A computer is no more conscious than a rock rolling down a hill - we program it by putting sticks in the rocks way to guide to a different path. We have managed to make some impressive things using lots of rocks and sticks, but there is not a lot more to it than that in terms of consciousness.

What are some ways to effectively practice and apply Maths learning?

I've been doing a lot of learning and found that practicing on paper is generally easier than Latex or a cobbled syntax in electronic documents, but would like to know if I just really need to bite the bullet and do it this way (Latex or similar).

Once I have (what I believe) an understanding of the problem types, I will generally write code to do it for me as doing this makes it even clearer in my head. Problem is though, once I do the code, I generally don't practice on paper anymore and I am not sure if this is going to be hindrance in understanding more complex topics.

My end goal is to be able to read and understand the maths in any AI focused research paper, and then be able to do some maths which isn't just practice examples but I am not sure on how to get to that last step.

Comment by djm on How do you take notes? · 2014-06-23T10:15:35.339Z · score: 5 (5 votes) · LW · GW

What are your strategies of taking notes for new information?

Start by reading random articles -> wiki -> papers / books Decide how complex it is likely to be for me and how far deep I want to learn the topic (e.g. how useful is this to me for really learn this)

Do you take any notes on paper? If so do you scan them or otherwise digilatize them?

Used to do notes on paper in bound books, a book per area (ideas, programs, building, etc) but never digitized them. For the last few years I use Google docs - like evernote, easy to search, write and read anywhere.

I still do Maths problems of paper as it seems quicker to scribble and draw diagrams / charts - would love to know a digital option though that worked as easily as pen.

Do you have specific strategies for deciding which information to write down?

New document for each topic to learn , or application of knowledge. e.g. document "Learn maths" - progress of maths courses , "AI applications" = how to actually build something.

The usual structure of a document is

*Overview - what is it, what do I want to learn

*Progress - what do I need to do, current tasks, upcoming tasks

*Application of Knowledge - ways to apply the knowledge - for me, usually software / website. I feel I need to actually apply new knowledge otherwise it doesn't stick after a few years. This section often has links to other project documents

*Notes - sub headings as needed, usually a 2-3 sentence summary of the area, links and the actual content contains things I didn't know / should learn / not obvious

*Log of Events - dated entry of when I read, learn or apply the knowledge

How do you write notes to capture all important information?

I don't - I only write down things I don't know, paragraphs usually with links to appropriate sources for deeper reminders. I find actually typing in my own words helps best for me to learn.

Do you tag your notes?

clear use of of document titles, standard sections, make sure right keywords are in the document (anywhere) and Google makes it very easy to get to the right document

If you use Evernote, or a similar system how private are your notes? Would you allow friends to read in them? Your spouse?

All notes are private by default, but some code I write as part of applying the learning is public e.g. - github. My spouse isn't at all interested in Maths or AI but would happily share if she wanted to read them
