Re: [Math] Catching RuntimeException
Le 06/10/2011 22:36, Gilles Sadowski a écrit : Hello. Hi Gilles, In the code in the following classes BaseMultiStartMultivariateRealOptimizer BaseMultiStartMultivariateVectorialOptimizer there is a catch(RuntimeException e) This contradicts the statement (in UnivariateRealFunction) stating that user-defined exceptions are never caught by CM. Not really. The exceptions are catch in order to allow a retry, which is the exact purpose of multi-start. If everything fails, the last exception is rethrown. OK. How to deactivate the CheckStyle warning? We can use checkstyle filters. I have fixed these as of r1179947. Thanks for spotting this.

On Thu, Oct 06, 2011 at 07:52:55PM -0500, Greg Sterijevski wrote: If you really think about, all of the decomposition classes should be handled by factories. The decompositions all seem to occur in the constructor. Everything else is derived from those results, so one could argue that the actual decomposition code could be written very procedurally and put into the factory as a static private method. The returned class from the factory would be nothing more than a container of the results and methods to get the data and derivatives of the data. Sorry, but I don't see the logical link between all calculations occur in the constructor and factories. That's why I had been expecting a real example that would clearly show that the current applications of the decomposition classes could be more elegantly and/or efficiently be dealt with in a design based on factories.

Re: [MATH] Re: Pivoting QR Decomposition: Take Two!
Hi. Yes, this application would be similar to the ones you nixed. It would be a factory returning an abstract class, with the appropriate methods throwing exceptions (like getRank for the non-pivoting version-as Ted mentions in a later entry in this blog). As Ted asks, what is the issue with this? What I'm asking is: What is the issue with 2 concrete classes (and possibly an abstract base class, if there is some code to share)? The issue is that the different classes are really an implementation detail from the user's point of view. What they care about is rank-revealing or not. They don't really care about pivoting except insofar as they know that is how rank revealing QR is done. OK, then the pivoting implementation should preferrably be in a class named RankRevealingQRDecomposition? It can be done with multiple classes, but just as java collections and now guava provide constructors that hide implementation details but expose user details, I think that this is good practice elsewhere as well. I agree. The question is to identify the interesting specifics. In this case, if getRank() is interesting, it should not be the result of an implementation detail that, if not present, would generate an exception. For example, if you say Maps.newHashMap(), do you *really* care which hash table implementation you get? No. But this case is not the same since the user will choose one or the other implementation based on his knowledge that he will be able to obtain, or not, something from getRank(). Having * one class per implementation, or * 2 implementations in the same class and selecting one or the other by passing a boolean, is exactly the same for the user. For the developer, I contend that it is tidier to separate the algorithms along class boundaries. [As Ted pointed out, the CM design is not based around factories (which is fine IMO until proven otherwise); changing that would require a strong argument and should lead to a complete revision of the basic layout of the library, in order to be consistent. Maybe for 4.0 :-).] Sure. Whatever. (checking out) To stretch the argument, why not create a UniversalDecomposition class with all the methods in it: Because that is just a straw man argument that isn't directed toward making things better. Just because an extreme form isn't right doesn't mean that moving that direction isn't a good idea. To paraphrase, I would like to find a minimum of (x-1)^2. Starting at 0, I could say that moving to 0.5 is good. You could say that the value is much larger at 20 and therefore moving to 0.5 is a bad idea. getCholeskyL() getLuL() getLuU() getLuP() getQrQ() getQrR() getQrH() getSvdU() getSvdS() getSvdV() ... and throw UnsupportedOperationException as necessary? Most of the Java world got past this many years ago. I'd be interested by a pointer. I'm all for CM to be state-of-the-art but it should be done in an orderly fashion lest someone dropping in some months/years from now will not be able to figure out what were the guiding principles in the design. If the design is coherent, it will be easier to modify it globally to adopt a new paradigm. On the other hand, if the library uses mixed coding styles, it will become extremely difficult to figure out why one style was used here and another there, and if it was done on purpose or just on a whim of the programmer.

/** - * Sinc function. + * Sinc function, defined by precode + * + * sinc(x) = 1 if abs(x) 1e-9; + * sin(x) / x; otherwise + * /code/pre I would not document the first part of the alternative since it is an implementation detail. 1e-9 was chosen just because, with double precision, the function value will be indistinguishable from 1. Strictly speaking it is not part of the definition of sinc. [This part of the implementation could even be removed if it is deemed that we lose more time doing the check than we gain when the user asks the value of points below 1e-9.] Also, there probably should not be a ; after the statements. If it a) makes a difference in the returned result and b) is correct (up to double equality), I don't understand what you write here. What I meant above is: For values 1e-9, it does not make a difference at double precision whether the computation is done in full (sin(x) / x) or by assigning 1 directly. I think we should leave the check in Yes, of course; the suggestion to remove it was a mistake (see below). and document it. We should always document top-coding or other departures from the formulas we define things by. I don't see why give a wrong definition since it makes no difference. The definition of sinc is[1]: sinc(x) = sin(x) / x To compute it, care must be taken to not divide by zero, thus the simplest operational definition is[2]: sinc(x) = 1 if x = 0 sin(x) / x otherwise The one in CM is an efficiency improvement (to avoid evaluation of a sine and a division when the result is indistinguishable from the known result). The rationale for the shortcut could be a code comment, but as a user-level comment, it is confusing. Gilles I am fine changing the semicolons (which are being used as punctuation) to commas or even dropping them altogether.
