| @Dave Map[f, {{1, 2}, {7, 2}, {5, 4}},{1}] results in the expression {f[{1,2}],f[{7,2}],f[{5,4}]} which is not the same as the result of evaluating f @@ # & /@ {{1, 2}, {7, 2}, {5, 4}} which says to Map the function f onto the heads of each of... |
| Hi Peter In answer to your query about Radial Basis Function (RBF) networks, the Classify function, see http://reference.wolfram.com/language/ref/Classify.html has the Option Method->"SupportVectorMachine" which now has a sub-method... |
| I have not been able to do anything with these functions. For instance removeStaffLines has undefined functions imageMin and imageMax. But there is a reference to SegNet and its GitHub source file at... |
| There is the MATH-TWS package by Jonathan Kinlay which connects Mathematica and IB's TWS trading system and which was described in the Wolfram Community site at https://community.wolfram.com/groups/-/m/t/1527021 Michael Kelly WRI |
| Diego You may find this affine wealth model that was outlined recently in Scientific American by Boghosian et al very interesting: https://www.scientificamerican.com/article/is-inequality-inevitable/. The original published article is also... |
| Thanks Diego for this analysis, it is very instructive. However as you point out at the beginning this depends upon a voluntary effort by nearly 18000 law enforcement agencies. I did a similar analysis in 2015 related to the number of black deaths by... |
| Thanks William for the detailed explanation. I appreciate it. If it is still ok, I would like a copy of your code so that I can play around with it many Thanks Michael |
| roseRingsetCF might be defined something like? roseRingsetCF=Compile[{{\[Theta], _Real},{r, _Real},{\[Theta]0, _Real},{d, _Real},{n, _Integer},{\[Alpha], _Real}},Module[{t1,t2},(*2 part composite curve*)t1=Sec[2 ArcTan[Cot[n... |
| Igor Thanks again for an interesting post. You may be interested that Will Shaw did something similar in evaluating zero coupon and yield curves in his book "Modeling Financial Derivatives with Mathematica". Is it possible that you could also... |
| Thanks very much Igor for this second explanation. I strongly appreciate your going into the details here. Your comment that "Although I use the same notation, the process for the inverted FX rate is different and it results in a different Ito SDE... |
