Re: Do you agree with Yann LeCun about Deep Learning being dead and "Differentiable programming" being the next hot thin

Not sure why say it's not relevant in finance. It's very relevant.  There was a huge body of work being on adjoint differentiation in quant finance a fairly long time ago. Many major IBs have such features in their systems.  For once, it feels like quant finance was significantly front running the M...

Re: Machine Learning and the physical sciences

Looks like a very biased review by a bunch of people who assimilate the physical sciences as being condensed matter physics... Pretty much. There is a large number of fields forming part of physical sciences where I can see this sh!t being useful, too. Did you mean a Bayesian network or a Bayesian n...

Re: Quantlib design and usage

So, a couple of observations... FWIW... At a high level, what strikes me as odd is that the library mixes up the 'what' of financial engineering with the 'how' at the very deepest level. There is way too much run time logic based into the basic class structure, much more than is desirable. Even 15 y...

Re: EOM rule subtleties in the swap market

No I think you are right actually. I was just checking in Bloomberg for you and fonud empirically that there any short front stub less than 7 days gets folded into the first coupon period. I then found that this is what opengamma strata call smart_initial. Have a look http://strata.opengamma.io/apid...

Re: EOM rule subtleties in the swap market

I assume you care about the 1M floating leg? Start with 1/30/2019, which being a good business day is the swap effective date. Add 13M unadjusted, which takes you to 2/29/2020. Now backwards roll out an unadjusted swap schedule assuming end-of-month roll. That gives you 13 periods. Finally adjust t...

Quantlib design and usage

I have had to turn my attention towards quantlib lately, in view of using it as a base for a system in a buy-side context, that is able to handle both valuation, risk, pnl as well as research in time series and scenario context. One important question I am trying to answer for myself, is how I shoul...

Re: convexity adjustment

bearish: ehnt It depends what you call a convexity adjustment.  If you define it as the adjustment that needs to be made to the expected value when valueing the index of interest under a measure other than the index's natural measure, then the convexity adjustment can be of either sign. This is a me...

swaption implied vol under CSA discounting

What is the current market practice on the dealer side for quoted european swaption premiums or implied volatilities under various CSA discounting schemes.  Specifically, in terms of the underlying swap.

commercial quant analytics library

Hi, 

please recommend a commercial quant analytics library for use on the buy side mostly with linear (some non-linear) fixed income.

Should have fairly cutting edge curves building technology.

Needs to have an API.

Thanks very much!

Re: Quantitative methods in magic

Applications of maths and computers in magic are still undervalued. To start with https://arxiv.org/abs/1709.03803
Why do you think it's so bad? do you mean the execution of the authors is bad or do you mean the whole approach is just idiotic?
