Is anyone into this? Pyrros perhaps? If so can you recommend a book or website or online course which is good for someone who knows a bit of probability and statistics theory?

Thanx @ulf bro. Back in my day I was superb. In my UNIV, probabilities I, we (compu science) took together with the math department. On the final exam, only two ppl passed from the whole univ (CS + maths) : me (8.5/10) and another guy from maths dept with 5.5 ... yeah.... those were the yearz of my glory ... Yep, big data, stats, DBs, this is my thing. I wanna progress not stay in this funking job I am till I die. Too bad in greco collony there are not many opportunities.

aha I used to be a PhD candidate for data mining, machine learning, AI. Nowdays, datamining is not so popular as a term. Anyways. I am sure you can find tons of material online. Now the buzz word of choice is BigData, any freaking psychologist is using it without having a clue.
BTW, what I noticed with greek scientists/doctors. They *are* good. But they are lousy as far as their communication skills are concerned.

I was recently at one data science conference and I can tell you what I heard (I'm not data scientist) is that its rather big job market in cities such as Berlin or London. It still didn't reach us here, and I'd wait to see the hype cycle pass, but I need to know more about it as I'm not math PhD such as you but what I graduated is something similar yet different (in popular terms - computational engineering) and we had no such subject. By the way, this is the reason I gave up on my PhD, when I saw how poor our masters program was.

Hey @ulf , I also dumped my PhD when I met my (current - Slavic) wife , some 20 yrs ago. But computer science is more Math-related than elektrotehnika, which is more traditional electrical-engineering, which was transformed into computer-engineering some decades ago. But its a hype. Language R, python, nosql, etc are all related.
I see it in my work. This is truly needed, but it takes determination to acquire the skills and dedication. Someone cannot do 10 jobs at once and be efficient with all of them. (greko style)

I was talking of this: I would wait for positive and negative peaks to end. Right now job market hit positive peak, but as many businesses understand that they actually don't need data scientists to finish their tasks, they'll switch back to more traditional means and the job market for data scientists will enter the negative peak. In the end it will reach the straight line(plateau of productivity) as the need for this kind of job becomes more clear to employers. Still, as a computational engineer I think this area should be part of any computer related engineering/science program. PS. When it comes to efficiency I don't believe you can be efficient even if you are working on one same job but two different projects in parallel, not to mention more than one type of job.

I cannot believe the madness of my programmers, one of them wants to work on 3 projects at once and usually he screws up with all of them. The worst kind of quality. But hey, I have no power over them and in end wins "friendship" and "good heart". Yeah Greeko Management in GreColony.

Well, what you described is just junior programmers way of thinking, but I understand your point, project management is tough job especially when you have no say over who you'd hire.

I had a say back then when they got hired but we became "pals", I have no say regarding appraisals, salary raise, any evaluation, all those are unknown words in Grecolony . Basically Greco management is 100% at primitive-level , I hear stories from a friend of mine who got hired in Albania that even Albos are more organized .
And those guys of mine are no juniors at all, born in 1985 is not so junior.
But I myself I aint no angel. I am supposed to do management work but I have fortified my castle around my database and send away any enemy that could come close. That is, I put job security (being in my 50s) higher than playing this boring role, for which I have no tools at all. Greco businees

This kind of job sounds like a burden. Anyway, age is not relevant, a person could be at junior level even regardless of the date they're born. Its the knowledge they possess and environment they've previously worked what matters. I've interviewed some guys who had more than 10 years of software development experience and I decided to hire someone without any professional experience just because they proved to be better fit.

Almost a year later. I can say I found and taught myself quite a lot about machine learning since I've started this thread. I've been messing with different models in regression, classification, and even a bit about neural networks. The last one I plan to perfect more after my newest project, as the neural networks should be studied as a field of its own. I found out I could use it almost in any area where you're suppose to make some sort of prediction. From basketball (and/or other sports) to game development. Really use cases are enournous.

i did some neural nets in my univ years in Crete in 1991 IIRC. Cool yearz... I and another girl programmed some neural nets to recognize numbers in bitmap images. It was the years of SUN, suntools, sunview, gcc, just when X came into place. Yeah... pre www and http .. those wre the yearz of the early net...

I'm assuming feedforward neural network. Did you used sigmoid or perceptron activation function back then? (or perhaps a third kind?)

Ulf it was 30 years ago. I barely remember anything. If feedforward is the simplest kind, I guess that was it. But it was cool, first time I came across some professional C code. I was quite good, but emotionally unstable, thrash metal music and girls (who didn't love me) appealed much more to me than maths or computers. That said, I would not leave the workstation, no matter if it was 03:00 in the morning until my program would work flawlessly, no discounts on this front.

It depends on the kind of your business. I can assist you on bookkeeping services for small businesses online in UK You can unwind since Osome will handle all of your concerns and offer you with a competent business secretary.
