estimados, ajusté una superficie de respuesta con el paquete "rsm" de R y hago un grafico 2D de la superficie de respuesta con contour(), pero como el argumento de esta función es la superficie de respuesta ajustada y ésta se ha ajustado codificando las variables, de acuerdo a la recomendación de la documentación del pa...

...do los paquetes "caret" y "nnet". He probado las siguientes opciones: NN.1 <- train(R ~ V1 + V2, data = DATOS.Codificados, method = "nnet", maxit = 10000, tuneGrid = SIZE.DECAY, trace = F, linout = TRUE) donde R² = 0.9936, y AAD = 4.87 %, pero la forma de la superficie de respuesta es muy irregular, nada parecida al modelo obtenido con "rsm". NN.2 <- train(R ~ V1 + V2 + V1:V2, data = DATOS.Codificados, method = "nnet", maxit = 10000, tuneGrid = SIZE.DECAY, trace = F, linout = TRUE) donde R² = 0.9936, y AAD = 4.87 %, pero la forma d...

¡Hola a todos! Tengo el siguiente data.frame: p <- data.frame(id=c(1:6),cara=c(1,0,0,1,0,0),anterior=c(0,1,2,0,4,5),siguiente=c(2,3,0,5,6,0),superficie=c(1,2,0,1,2,0)) En realidad es muchísimo más grande, pero creo que las primeras filas servirán para explicar mi problema. El data.frame contiene los puntos de intersección entre fotones y superficies. Dichos puntos están identificados con el campo "id". Por otro lado, el campo "si...

Hola compañeros de la lista. Estoy aprendiendo a usar el paquete "rsm" para superficies de respuesta. Siguiendo este ejemplo todo va bien, hasta que trato de obtener el valor máximo predicho para la variable de respuesta en los valores de x1 y x2 estimados. ------------------------------------------------------------- library("rsm") ChemReact CR <- coded.data(ChemRea...

...para ajustar un modelo mixto. Tengo varias variables en mi data.frame, unas son a nivel individual y otras a nivel de comarcas. Listo algunas. ingre_6 : Ingresos (nivel individual) iscs_a : un indicador sintético resumen de otras variables, calculado mediante componentes principales. sau_com : superficie agraria útil de cada una de las comarcas. cod_com : código de cada comarca. 44 en total Quiero incluir sau_com como predictor a nivel de comarcas, pero no sé si también tengo que meterlo a nivel individual yo hago. library(lme4) mod.ingr <- lmer(ingre_6 ~ iscs_a + (sau_com | cod_com) , dat...

...ed. This allows the full attributes of a file to be stored without having to have the daemon actually running as root. -dit(bf(filter)) The "filter" option allows you to specify a space-separated -list of filter rules that the daemon will not allow to be read or written. -This is only superficially equivalent to the client specifying these -patterns with the bf(--filter) option. Only one "filter" option may be -specified, but it may contain as many rules as you like, including -merge-file rules. Note that per-directory merge-file rules do not provide +dit(bf(filter)) The daemo...

I completely agree with John here - we had a case a few years ago where someone spent ages refactoring their algorithm to be iterative and was surprised that it became slower (with the MS compiler). Looking at the assembly, it was using p...

...ATLAB (la última vez que había usado este programa fue en 1999). ¿Alguno de vosotros ha trabajado en R? ¿Podríais hacerme alguna recomendación de funciones o librerías a probar? Lo que querría es: 1. Calcular el NURBS de una nube de puntos. 2. Determinar las distancias mínimas de otros puntos a la superficie NURBS creada. saludos y muchas gracias, Fernando [[alternative HTML version deleted]]

I am new to LLVM but have perused the code alongside using llvm-gcc and CLANG to build ARM EABI objects. Based on this superficial analysis it appears that LLVM currently does not support the ARM Exception Handling ABI (as defined under the EABI). Can anyone comment on whether plans are in place to remedy this? I did see the discussion regarding work on the MC for ARM. Will this work include emitting the exception handling...

Hi, With the new llvm-mc code for disassembling, what is the recommended way to disassemble the final code produced by a JIT compiler backend? (Eg. in the toy.cpp example from the tutorial). I can get the void* for the final code, but I don't know its length - superficially at least it appears I need to know the length to disassemble it as a buffer? Thanks b.

Hello David Chisnall, John McCall, David Blaikie and other people who may concern > If your teachers are really making this sort of superficial generalization, > they're doing you a disservice. This hit my head. Actually I didn't test the performance of those two, the iteration and the recursion, at all. And in this field of study, testing is very much important, I believe. And the '''tail call optimization'&...

This is not a trivial question, and I'll let others chip in. Superficially, you'd think so and it might make sense in the long run, but you have to consider why it wasn't there in the first place. It may be that it didn't need to (in which case, it's ok to move), or it may be that the design of MC needed those headers to be more private (in which case...

...s used: > > - simplification of infinity/NaN expressions > > - combination with FMA introduction Well no, my comment also applied to the FMA introduction. Stephen was a bit hesitant about what to call the x * (y + 1) --> x * y + x FMA-introducing transform on the grounds that it superficially only seems to improve the precision at which the expression is evaluated. My point was that this very same transform can introduce very significant, qualitative differences in the result when inf is involved.

Just thought I would mention that there is a new O'Reilly book out, "Developing Bioinformatics Computer Skills", which is ok, pretty superficial about some things but at least it lets you know what is happening and where. R gets a few pages in there, 394-396, mostly nice press and accurate except that Bill Venables (hi Bill) may be surprised to find out that he is a member of the core development team. Robert ps: they also have an Xgobi...

I think the conceptual issues have largely been sorted out, it is mostly that it is *much* harder to deduce norecurse than it might seem like superficially.
