deep classification network with "logsig layer" instead of softmaxLayer

Hello,

I want to create a deep classification net, but my classes aren't mutually exclusive (what sofmaxlayer do).

Is it possible to define a non mutually exclusive classification layer (i.e., a data can be in more than one class)?

One way to do it, it would be with a logsig function in the classification layer, instead of a softmax, but I have no idea how to acomplish that....
