r - GBM multinomial distribution, how to use predict() to get predicted class? -


i using multinomial distribution gbm package in r. when use predict function, series of values:

5.086328 -4.738346 -8.492738 -5.980720 -4.351102 -4.738044 -3.220387 -4.732654

but want probability of each class occurring. how recover probabilities? thank you.

take @ ?predict.gbm, you'll see there "type" parameter function. try out predict(<gbm object>, <new data>, type="response").

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array?
