let's data has both numeric & catagoricial feature, , i've created xgboost model using gblinear. i've analyzed xgboost model xgb.importance, how can express categorical variable weights? while xgboost considered black box model, can understand feature importance (for both categorical , numeric) averaging gain of each feature split , trees. this represented in graph below. # feature real names names <- dimnames(trainmatrix)[[2]] # compute feature importance matrix importance_matrix <- xgb.importance(names, model = bst) # nice graph xgb.plot.importance(importance_matrix[1:10,]) in feature importance above, can see first 10 important features. this function gives color each bar. k-means clustering applied group each feature importance. alternately, represented in tree diagram (see link above).

i've been learning boost asio recently, udp. familiar basics, had question regarding how udp handles incoming messages. in tutorial (see source code here: http://www.boost.org/doc/libs/1_54_0/doc/html/boost_asio/tutorial/tutdaytime6/src.html ), udp server operates (very pseudo-code): startreceive(){ async_receive(boost::bind(handler),...other params); } handler(){ dostufftodatareceived(); startreceive(); //start receiving process on again allow receive more data } my question is, if data arrives server during time in "dostufftodatareceived()", before startreceives on again, data lost, or sit there , wait startreceive happen again , retrieved? thanks! udp stack has buffer, data in above example wouldn't lost. note however, udp allowed drop packets under various circumstances. so, throughput of udp server grows, timings of dostufftodatareceived might become more critical.
