    Nvidia site in deep machine learning is (predominantly) on image recognition. In this domain the deep learning (i.e. convolutional neural networks with many hidden layers) really kicks ass. In financial area the deep learning seems to be more hype that a breakthru technology (IMO). For instance...

    Investing (vs. Speculating) in ETFs

    Not every single trade but generally I do not spare comments, that's why I have a badge "Guter Kommunikator". It depends. The decisions are both technically and fundamentally (micro- and macro-economically) based. I also try to cut losses quickly.

    Investing (vs. Speculating) in ETFs

    Hi, often investing in an fund means trusting the fund manager and relying on funds historical performance (which, however, does not imply good future performance). And of course you should be more specific on what you mean with ETF. This term is indeed often used for the funds that just...

    With or without recruiters

    It may really depend on your location but for the German market the answer is definitely without. First of all many "headhunters" are just CV-pickers and they even publish fake job-ads (they need a big CV database to attract customers). Second, the candidates that come via recruiters are more...

    What do you Pros do? Time Series Analysis

    You are welcome and thank you for your interest to my book. I hardly discuss time series analysis in it (otherwise a target audience would be much narrower) but I do show how to engage the power of R (all scripts can be downloaded here: http://www.yetanotherquant.com/rcode.zip)

    What do you Pros do? Time Series Analysis

    If you don't like cats, likely, you just cannot cook them properly! :D R is a great tool with a great amount of (not always great) packages. As to fitting a time series model to the real data, it is both art and science. Don't expect to learn it from profs that never dealt with real-world...

    Would like to verify current concept of Quantitative Researchers and Quant PM's

    >I was surprised that you said BSc. is enough. Just to make it clear. I, myself, have an MSc (was necessarily to to make it in Germany in order to get a work permit there). I also have written (though not defended) a Ph.D. thesis because I love researching. I needed an advanced and complex...

    Would like to verify current concept of Quantitative Researchers and Quant PM's

    Don't put too much hope on Msc and Ph.D. Ph. D. (unless done parallel to job) is a waste of time, Msc. will not hurt (but if you are going to trade only primary assets - stocks, bonds, commodities - not derivatives, BSc. is enough). And - practice, practice, practice! Start building your track...

    Best way to hire new quants without recruiters

    Neither qualified employees like them. I, for one, encountered several times a situation, as I tell a "head hunter" about my experience with interest rate modeling and then she asked whether I have knowledge in fixed income. How about publishing a job-ad on this forum, on...

    Do you believe markets are efficient?

    BTW, yesterday I was again better than market. Most of "experts" believed that the Supermario would not shock the market. My idea was: ok, to be on the safe side I sell and after his report I buy back. I did buy back but at much better prices ;)

    Electricity, Power price hedging

    Hi Sebastjan, I do. It is a job of supplier, i.e. of your employer. A distributor (if you mean Netzbetreiteber/network operator) is technically responsible for a smooth supply of the end-customer (even if a supplies, i.e. your company) reserves (nominates) a not (perfectly) correct amount of...

    CFA vs FRM vs PRM for Hedge Fund

    1. and 2. - yes but I highly doubt the power of 3. and 4. (I mean 3. and 4. may help and definitely won't hurt but do not expect too much from them)
