Hi R help, I run my data in nnet with skip layer, factor response (with 0 & 1 values) and explicitly put softmax=T to compare the result of the default nnet with no softmax specification. I assume this should give me the same result. I got the result the default one, but not the softmax version and I got the error message that I did not quite understand.
test6.nn.skipT.softm.Yfac <- nnet(Yfac~ X1 +.. +X8, skip=T, size=0, softmax=T, data = train.set) Error in nnet.default(x, y, w, entropy = TRUE, ...) : no weights to fit In addition: Warning messages: 1: In if (softmax) { : the condition has length > 1 and only the first element will be used 2: In if (skip) net <- add.net(net, seq(1, net$n[1]), seq(1 + net$n[1] + : the condition has length > 1 and only the first element will be used When I specify the weights (0.1 just for a try) test6.nn.skipT.softm.Yfac <- nnet(Yfac~ X1 +.. +X8, skip=T, size=0, weights= 0.1, softmax=T, data = train.set) I got another error message: Error in model.frame.default(formula = Yfac ~ HusYEduc + AgeRespd + muslimat + : variable lengths differ (found for '(weights)') ----------------- Q: Does softmax apply to two-category response? What is softmax require?
