英文:
Define parameter1 as 1 - parameter2 using R paradox package
问题
我想要使用paradox包将parameter1定义为1 - parameter2。这意味着parameter1依赖于parameter2（我认为depends参数在这里不起作用）。
这是我的研究空间：
search_space = ps(
# 数据预处理
interaction_branch.selection = p_fct(levels = c("nop_filter", "modelmatrix")),
winsorizesimple.probs_high = p_fct(levels = c("0.99", "0.98", "0.97")),
winsorizesimple.probs_low = p_dbl(lower = 0, upper = 1),
# ranger
ranger.ranger.max.depth = p_fct(levels = c(2L, 10L)),
ranger.ranger.splitrule = p_fct(levels = c("gini", "extratrees")),
ranger.ranger.mtry.ratio = p_dbl(0.5, 1),
# kknn
kknn.kknn.k = p_int(1, 10),
# 额外的转换
.extra_trafo = function(x, param_set) {
winsorizesimple.probs_high = switch(
x$winsorizesimple.probs_high,
"0.99" = 0.99,
"0.98" = 0.98,
"0.97" = 0.97
)
x$winsorizesimple.probs_low = 1 - winsorizesimple.probs_high
x
}
)
输出如下：
interaction_branch.selection winsorizesimple.probs_high winsorizesimple.probs_low ranger.ranger.max.depth ranger.ranger.splitrule ranger.ranger.mtry.ratio kknn.kknn.k
1: nop_filter 0.99 0.01 2 gini 0.5000000 1
2: nop_filter 0.99 0.01 2 gini 0.5000000 4
3: nop_filter 0.99 0.01 2 gini 0.5000000 7
4: nop_filter 0.99 0.01 2 gini 0.5000000 10
5: nop_filter 0.99 0.01 2 gini 0.6666667 1

我理解你的需求是将winsorizesimple.probs_low从-1更改为0.01，因此这是更正后的输出。希望这对你有帮助，不需要重新生成示例。
英文:
I want to define parameter1 as 1 - parameter2 using paradox package.
That is parameter 1 depends on parameter 2 (depends argument doesn't help here I suppose).
Here is my reserach space:
search_space = ps(
# preprocessing
interaction_branch.selection = p_fct(levels = c("nop_filter", "modelmatrix")),
winsorizesimple.probs_high = p_fct(levels = c("0.99", "0.98", "0.97")),
winsorizesimple.probs_low = p_dbl(lower = 0, upper = 1),
# ranger
ranger.ranger.max.depth = p_fct(levels = c(2L, 10L)),
ranger.ranger.splitrule = p_fct(levels = c("gini", "extratrees")),
ranger.ranger.mtry.ratio = p_dbl(0.5, 1),
# kknn
kknn.kknn.k = p_int(1, 10),
# extra transformations
.extra_trafo = function(x, param_set) {
winsorizesimple.probs_high = switch(
x$winsorizesimple.probs_high,
"0.99" = 0.99,
"0.98" = 0.98,
"0.97" = 0.97
)
x$winsorizesimple.probs_low = 1 - winsorizesimple.probs_high
x
}
)
The ooutput is:
interaction_branch.selection winsorizesimple.probs_high winsorizesimple.probs_low ranger.ranger.max.depth ranger.ranger.splitrule ranger.ranger.mtry.ratio
1: nop_filter 0.99 -1 2 gini 0.5000000
2: nop_filter 0.99 -1 2 gini 0.5000000
3: nop_filter 0.99 -1 2 gini 0.5000000
4: nop_filter 0.99 -1 2 gini 0.5000000
5: nop_filter 0.99 -1 2 gini 0.6666667

I winsorizesimple.probs_high1 is 0.97, winsorizesimple.probs_low should be 0.03.
Hope you can help without reprex.
