I'm specifically asking programmers and other people who actually know what they're talking about this question.

Can you make AI capable of learning without making it capable of free will? Even as AI gets more and more advanced?
98 posts and 15 images submitted.
>>
what do you mean by learning ? Machine learning algorithms already exist, but they're way too specific to ever reach sentience.

I'm guessing you mean AI for futuristic general use robots, like in sci-fi. In that case I don't think anybody can tell for sure, personally I'd say no, but that's really debatable. Before being able to discuss this you also need to be able to define what free will is, which is a huge debate on its own.
>>
>>8629120

Free will is superstructure of self-consciousness, which arise when map of environment can't evolve any more without including itself.

It ceases during further development, as subject gains more insight into it's own impulses and constraints.

So answer is yes, AI doesn't need free will.
Yes again, it will develop one as it evolves, then if true AI - outgrow it quickly.
>>
I think the entire concept of an artificial general intelligence is very much defined by the idea that the AI would have free will, or as much free will as you or I have if you want to be a pedantic philosopher about it.

But yes as anon mentioned, computers and deep neural nets can already 'learn', although I suspect that's not the narrowly-constrained type of learning that you're referring to.

You need to learn how to organize your perspective, understand that anger is just a certain kind energy running through your conciousness, you are not it, distance yourself from it, understand what exactly is it inside of you that gets angry and why, direct your awareness to reason, to calmness, meditate, and then approach your life in a state of mind that's appropriate to the situation at hand,not out of excessive ego and anger,but by a longing to instill true goodness and utilizing it.

I recomend reading Aristotle’s nico ethics, Marcus Aurelius' Meditations, and Aldous Huxley's Eyeless In Gaza for a good start

Do you think the universe's laws, the laws of physics are just the universe's way of preserving intelligent life?
Made that way just so only intelligent enough life forms may save themselves by unlocking it secrets and (in the case of multiverse theory) traveling to a new universe before the death of the current one? Kind of like evolution on the larger scale , on a one which intelligent species are the ones who live.

Statistics and probability in ML? lmao
I attended a ML lecture once, I'm not even sure the professor himself knew what a probability distribution is.
To save ML there's only one way. We rename the subject Statistical Learning to spark the interest of mathematicians. Once the mathematicians specialised in Statistical Theory get into it, we'll see advances in ML that would take 100years for computer scientists to come up with.
>>
>>8635923
Problem is, I'm not even interested in Statistics (pure math guy here). I am interested in CS. But it seems like everyone and their mother is interested in ML and few of them understand the Statistics/Probability/Linear Algebra background required to understand the basics. LA is fine, I like LA, but I cannot stand Statistics/Probability because I find it boring. These "bootcamp" peeps are jumping in on the point and click technologies that enable basic statistical analysis and call themselves "Machine Learning experts" lmao.

I was wondering if I am the only one that:
1) See most "Data Scientist" lack basic understanding to do serious ML

and

2) See ML as a bunch of hype and have a lack of interest in Statistics.

I've been thinking about this for some time now: all life is made out of organic molecules (which aren't alive). If that's true, which it is, how can a living thing be made out of non-living things? And if life is maintained through chemical reactions, then at what point can we say that a bunch of interconnected chemical reactions are life?

Life is considered a characteristic of something that exhibits all or most of the following traits:[11][13][14][15][16][17][18]

Homeostasis: regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
Organization: being structurally composed of one or more cells — the basic units of life
Metabolism: transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolism). Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life.
Growth: maintenance of a higher rate of anabolism than catabolism. A growing organism increases in size in all of its parts, rather than simply accumulating matter.
Adaptation: the ability to change over time in response to the environment. This ability is fundamental to the process of evolution and is determined by the organism's heredity, diet, and external factors.
Response to stimuli: a response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis.
Reproduction: the ability to produce new individual organisms, either asexually from a single parent organism or sexually from two parent organisms.

>>8635720

How can a house be made out of non-house bricks? The whole is more than the sum of its parts. Life isn't a "thing", it's not a "property" that we have, it's a process, a continuous slow-speed chemical reaction. It's not some spooky thing that pops into existence when a new human is born, it's just a continuation-- and elaboration-- of the same exact physical and chemical processes that take place in non-living systems.

>I've been thinking about this for some time now: all computers is made out of semiconductors (which aren't computers).

Hey /sci/.
The other day I had a shower thought about IQ-tests, and I thought I'd ask here, in case someone knew the answer.

Afaik, IQ-tests are normalized around 100, so that "the average" person will have about 100 IQ, and some will have more, some less.
But at what scale is it normalized?

I mean, if you normalize it country-wide then you cannot document potential differences in IQ across country-borders, because each country will average 100.

The best thing would be normalizing across the globe, but that would require standardized testing across the world.

And also, it would fail to adress that things like language-structure affects your way of thinking, so that a test authored by an arabic professor might favor naturally arab-speaking people, and handicap others, even after being translated competently.

So how the fuck does IQ get compared in any meaningful way, across cultural divides, and large geographic areas?
And at what scale does the "100-score" so to speak, get set?

Pic unrelated.

>So how the fuck does IQ get compared in any meaningful way, across cultural divides, and large geographic areas?

...by their scores.

The normalization is just convenience. The real global average could be 120 or 75; either way doesn't matter.
>>
>>8635642
>>8635642
The point is that the test is not a test of "absolute" intelligence. It's a test of comparable intelligence.
The average score is set to be 100.

So if Country 1 tests 1500 citizens, and then figures out how well they did on that test, they would call the average test performance '100', and then define their distribution based on that.

If country 2 did the same with their own test, the average would again be 100, and comparing the two countries citizens would be difficult.

Everyone in country 1 might potentially score 150 by the standards of country 2s test, but both countries have an "average" IQ of 100, because it is defined as the average score.

So whether we call it 75 or 120 doesn't matter, but how we normalize it across large geographical areas absolutely does.
>>
>>8635667
You're assuming that each country sets their own scale.

There are various IQ tests, all already defined and normalized by the group or person who made them. It's done. The comparison is always in relation to their definition base, and that's why they are comparable no matter where you are.

Hi sci, I have a problem I need help solving.

I have a given set of data [2, 4, 5, 7, 10] and the expected value or the mean of E(x) = 6. How would I get the probabilities of each value in this set based on this formula E(x) = 2 * P(2) + 4 * P(4) + 5 * P(5) + 7 * P(7) + 10 * P(10) or E(X) = Xi * P(Xi), P(Xi) is the probability for a given X

>>
P(X=5)=P(X=7)=1/2
P(X=anything else)=0

You're welcome.
>>
Also

P(X=2)=P(X=10)=1/2
P(X=anything else)=0

You're welcome.
>>
Hmm..

The thing is I need a formula to generate this models dynamically, meaning the values in the set are always changing and I can't use a static model

I completed a pure math degree. Enjoyed it. Recently stumbled across some areas of CS that interest me (Cryptography & Data Engineering). I like to formalize my studies (aka mathematicize these areas) to the extent that my interest in these particular areas differ a bit from regular CSfolks.

I don't quite relate to "Security Engineers" and my interest in Cryptography relate a bit with Algebraist and Number Theorist but differ wrt to applications.

Anyone else similar? Where do mathematicians like us fit if we have an interest in CS?

No problem. I am also quite interested in that area as on top of majoring mathematics, I do a lot of programming and am interested in mixing the two. That said, I still don't have a degree and I am just sophomore so maybe I'll have to wait before I do some serious work there. I'd like my senior thesis to be something in this field but I'll have to see.

Graduated last year with a bachelors in nuclear engineering.
I currently work as a physicist, and am interested in going back to school for a masters (just coursework, no thesis), in either physics, applied physics, nuclear engineering, or medical physics.

I live/work in Georgia, so Tech is the likely choice.
Any recs on what I should major in? I work for a medical device company that develops and manufactures brachytherapy seeds, and other associated products.

Also any insight into whether I should study on campus or take online classes?
Not sure about medical physics, it sounds great and I'd like to learn more about the medical side and treatment planning, etc but idk if I want to do the hospital rotation for two years.

Anyone have any experience with medical physics that could tell me a little more about what it's like and how your experience went?

Also will answer any questions about brachytherapy, radiation, etc.

See if your company will pay for your Masters. I cannot speak for MS degrees in your field but Tech has an online CS masters that is popular.

Also, just throwing out look at NCSU for their nuclear engineering department. They are a top 10 school in the field. But Tech probably makes more sense if you want to stay local.
>>
>>8635569
Yeah a few guys I did undergrad with are at NC State for grad school. If I still lived up north (I did undergrad at Purdue) I'd just go to Michigan and be done with it.

I know Tech has an online Med Phys program and then the clinical rotation, but I have to look more into what else they offer online.

My boss got his PhD from Tech so I'm going to talk with him about it too.

There's also Emory to consider.

Do a masters or PhD in materials science and then go work in fusion

It'll be enjoyable and it's an industry which is now rapidly expanding in order to get fusion by 2050~. There's high demand for jobs especially in fusion research and lots of money
